|Nexus 7 slow when less than 3GB free||Paul.Cahill||9/9/12 7:36 PM|
Many are finding the Nexus 7 runs very slowly if the storage has less than 3GB remaining. Benchmarks show that I/O speeds drop sharply especially for writes.
I have opened a case with Asus. Could others please do the same if they are having this problem. The Nexus 7 does appear in the dropdown if you choose product type eeepc.
There is an issue with the 16GB Nexus 7 that many people are finding.
If this tablet is filled up with files, e.g. video or music files, until there is less than 3GB free, the tablet dramatically slows down. Apps are very slow to load. The interface becomes jerky.
Benchmarks show very slow sequential and random writes. This appears to be the cause of the issue. The only solution appears to be a factory reset. However the problem will come back.

Deleting files to free up space does not help. Only a reset will. This is with 5GB free having been down to 2GB free.

|Re: Nexus 7 slow when less than 3GB free||Kumnaa||9/10/12 4:18 AM|
I also have this issue. It only appeared once my Nexus had less that 2gb left (I had just finished uploading my music to it) but removing data to free up 8gb again didn't resolve the problem.
I've not done any benchmarking but purely from a usability view point Facebook and Chrome are the biggest indicators of an issue (at least for me). They both frequently report they've stopped with the option of 'Wait', 'Report' and 'Close' if you hit 'Wait' (once or sometimes twice) the app will finish loading and work as normal. Sometimes there will be a pause as it's loading once you're in the app (the spinning circle freezes and the 'Wait' dialog reappears) but after a while it resumes as normal.

I've just run Androbench and these are my results:
Nexus 7 16GB
Sequential Read 20.67MB/s
Sequential Write 0.44MB/s
Random Read 7.46MB/s 1911.07 IOPS(4k)
Random Write 0.05MB/s 14.52 IOPS(4k)
I don't know what they were before the issue arose but my Read speeds are comparable to the Galaxy Tab but my write speeds are the same as Paul.Cahill's. I have a working Nexus 7 at home that I will run the same test on tonight.

|Re: Nexus 7 slow when less than 3GB free||Salty Wagyu||9/10/12 5:45 AM|
Also had same issues as OP when device was filled up, freeing up space did not fix this so I had to flash a google factory image and start over again.
Some of the issues I had:
1. Google Play downloading updates - it would start off very slowly, perhaps 15KB/sec for roughly ten seconds before going to the max speed of my connection (~500KB/sec) per download.
2. Apps being unresponsive, delays in swiping up/down a page. The Wait/Close box would often come up, I chose wait and the app is eventually responsive again.
3. The Brightness gesture in Dice Player was also slow to react. The Volume gesture is however instantaneous.
4. Poor I/O score in Quadrant, the average is about ~1750 but I was scoring anywhere between 1000-1150 - https://dl.dropbox.com/u/12843960/Screenshot_2012-09-06-12-41-56.png I did not know about Androbench at the time so I don't have any results to share. The score went back up to 1764 after erasing and then flashing factory image.
I am now using a USB OTG cable to access video content I want to watch instead of putting it on the device to avoid filling up and causing poor I/O again. But I don't want this to be a permanent solution.
I have to ask, is Android cleaning out dirty blocks in the freespace areas of the NAND? I have a slight suspicion dirty blocks is the cause, as this reminds me of the past where first generation SSDs on Desktop PCs slowed down if they weren't cleaned. But I could be wrong.
|Re: Nexus 7 slow when less than 3GB free||mmaestro||9/10/12 7:23 AM|
I also saw this issue. It seems to be compounded by background push processes - I've seen it made worse by Out of Milk, Facebook, Currents, and Play Magazines, as well as other apps (but those were the most obvious). I/O drops through the floor and deleting items from the N7 doesn't restore I/O back, all that will fix it is a factory reset. The N7 becomes almost unusable with the lag present.
It seems likely that this is poor/nonexistant garbage collection in the NAND, given that deleting files does not fix the problem.

|Re: Nexus 7 slow when less than 3GB free||smacman||9/10/12 6:05 PM|
Same problem here. My 16GB Nexus 7 has literally become unusable ever since my free storage fell below 3GB. Much like others, I have freed up space but the lag remains.
|Re: Nexus 7 slow when less than 3GB free||smac3||9/11/12 3:50 AM|
Also experiencing the exact same issue after reaching less than 2Gb of free space.
|Re: Nexus 7 slow when less than 3GB free||sizov||9/11/12 6:32 AM|
same problem here. oedererd an exchange, but seems that it happens to all tablets which have <3Gb of free storage and there's no way to solve issue without factory reset
|Re: Nexus 7 slow when less than 3GB free||Paul.Cahill||9/11/12 10:14 PM|
I and maybe others have managed to get an article published on The Register.
However the commentards have missed the issue and think that owners are bleating that they only have 13GB and not 16GB or that it runs slow when 99% full.
Please comment on the article that write performance is still a tenth of what it should be, even when the file system is cleared down so that lots of space is free.
|Re: Nexus 7 slow when less than 3GB free||M.B.||9/13/12 6:05 AM|
I'm having this same issue on my 16gb Nexus 7, only I started seeing the huge lag/write issues after my remaining space dipped below 5gb. I immediately deleted the newest apps I downloaded and lots of music/games/photos, but the lag remains. Apparently the only way to fix it is to factory reset and never let your available space dip below a certain threshold (although apparently that number isn't exact, since some people don't see differences in performance until they get to 3gb or 2gb and I started seeing it as soon as I went below 5gb.)
This is ridiculous. 16gb is actually only 12 or 13gb of usable space right out of the box, and now I can't use 5gb of that remaining space because this lag is so bad it's making the Nexus 7 unusable and I don't want to have to keep factory restoring and wiping/re-adding everything if it happens again in the future, so unless I use an OTG SD card my shiny new Nexus is only good for 7-8gb of space?
Some media device. I have over 1.5gb of ebooks and comics alone. I guess I shouldn't expect to be able to read lots of books or play more than a few games or have a few gb of music and save a single movie and still be able to browse web pages or open apps without them force closing or grinding to a halt, how silly of me. Wish I'd known about this issue before I purchased. If only a 32gb version was available, I wouldn't have hit this stupid I/O breaking level of internal memory usage and could still use my tablet as a tablet.
I hope they can fix this with an update, because having to limit myself to 8gb of space or factory resetting every time I go over that limit isn't going to cut it.
|Re: Nexus 7 slow when less than 3GB free||Paul||9/13/12 10:39 AM|

|Re: Nexus 7 slow when less than 3GB free||lordlad||9/14/12 1:22 AM|
Hi Paul, thanks for reply. I've ever to 'fix' this by disabling fsync(). However, this shouldn't be needed (and i kinda worry for data integrity now).....
If the problem is really due to the hardware (poor IO performance of the Flash), then i would actually prefer Asus/google to at least inform us about this so that the community can devise a solution rather than firing on blanks right now...
Thanks in advance.
|Re: Nexus 7 slow when less than 3GB free||Nexx9||9/14/12 1:49 AM|
Same here. It started a week ago when I had 2G left, on my 8G from GPlay.
I'm amazed G hasn't said anything yet.
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||9/14/12 3:06 AM|
I'm thinking this is a hardware issue with sub-optimal units produced to meet launch demand (let's face it, it's hardly the first indication we've got that Asus cut corners). I'd appreciate if people popped the back off their tablet and looked at the build date and serial info printed on the inside of the plate.
Build date 2012/05/26
|Re: Nexus 7 slow when less than 3GB free||Charles Knight||9/14/12 3:38 AM|
Wouldn't we void our warranty by doing so?
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||9/14/12 5:33 AM|
There aren't any warranty seal in place so you can do so without any problems. Just don't go jamming screwdrivers into the motherboard while you do so.
|Re: Nexus 7 slow when less than 3GB free||dwoolley||9/14/12 8:32 AM|
Same scenario for me...slowness after n7 almost at capacity solved only by reset. One additional item I noticed while investigating was my cache reported itself as 2GB using ES File manager however individual apps reported far less.
|Re: Nexus 7 slow when less than 3GB free||mmaestro||9/14/12 8:38 AM|
One thing that I've noticed that I wonder if it's related is when I go to apps in settings, my used storage is initially reported as far higher than it actually is, and then over a few seconds it drops down to the volume of storage that's actually being used. I don't have slowdown right now after a previous factory reset, but I'm using ~4GB of space, however when I go look at apps, it initially reports ~6GB in use, and then drops down. I wonder if that misreporting of used space could be part of the problem?
|Re: Nexus 7 slow when less than 3GB free||Paul||9/14/12 2:14 PM|
Would a couple of you who are experiencing this problem be interested in helping us out by sending your Nexus 7 to us while it's experiencing the problem? We can send you an replacement before you ship your current unit to us so you wouldn't be without a tablet. If you are interested, please reply to this post (no need to post any contact info -- I can get that from your forum profile) and I'll have a shipping specialist get in touch with you with further instructions.
|Re: Nexus 7 slow when less than 3GB free||whoisrabbit||9/14/12 3:00 PM|
I am also experiencing this problem...Would there be a fix for it later that we will be able to get? Otherwise even with a replacement unit, this problem is gonna show up again very soon.
|Re: Nexus 7 slow when less than 3GB free||burnduck||9/14/12 5:02 PM|
I have an unit which has been repeatedly exhibiting this issue after 2 factory resets (I am the first one to post Androbench results on XDA with a side-by-side comparison picture), I am willing to ship the device to you but I purchase the unit through PCWorld in the UK, will that be an issue?

I have a unit that has this issue, that persists through factory resets, and sd card wipes. I have no qualms with giving you the unit as is.
Speeds can be seen here: http://code.google.com/p/android/issues/detail?id=37258#c27 I have also taken other screen captures of the unit.
|Re: Nexus 7 slow when less than 3GB free||burnduck||9/14/12 7:03 PM|
Just adding to that this issue is highly reproducible on my Nexus 7. I've done 2 factory data resets, first time by the FDR button, the second time by reflashing the stock rom, and I'm still encountering the "lag" or slow write I/O after certain period of usage. It is now at a point where the Force Close dialogue comes up as soon as the table is turned on and was still in the lock screen.
Pretty sure this is the unit you will need and really hope it's going to help since I like this little tablet a lot.
|Re: Nexus 7 slow when less than 3GB free||Dr. Cognitive||9/14/12 7:22 PM|
I would love to. I get incredible lag and I have plenty of free space. If I do anything requiring I/O, this thing basically is dead in the water.
|Re: Nexus 7 slow when less than 3GB free||frescagod||9/14/12 7:23 PM|
my N7 slowed down after a week, numerous reboots would not fix it, so i factory reset and it was fine again. fast forward a couple weeks and it lagged again. this time, i tooled around a bit and cleared 144MB out of chrome's cache in manage apps, rebooted, and the lag went away. i'm wondering if that is the cause?

16gb Nexus 7 ordered direct from Google Play in the UK, still having the issue after a full factory reset. By all means take it off my hands because it's about as useful as a £60 Chinese import at the moment.
|Re: Nexus 7 slow when less than 3GB free||bgilstein||9/14/12 10:16 PM|
Thanks for taking interest Paul, as we've been dealing with this for weeks over on xda with what felt like no sign of interest from the big G. I would be willing to send in my N7 if you need anyone else. I live in Santa Cruz and know a member of the Google Earth team if that would help speed up the process of switching out the tablets. Running stock Jelly Bean un-rooted.
|Re: Nexus 7 slow when less than 3GB free||Jyve||9/15/12 12:02 AM|

|Re: Nexus 7 slow when less than 3GB free||Kumnaa||9/15/12 12:05 AM|
You're welcome to take mine but being UK based that probably isn't as practical as taking a US based tablet
|Re: Nexus 7 slow when less than 3GB free||Nexx9||9/15/12 2:49 AM|

|Re: Nexus 7 slow when less than 3GB free||Levianco||9/15/12 3:00 AM|
You can have my tablet as well. Current storage capacity is at 1.37gb. I also had to disable HW overlays cause I couldn't watch almost any video without the screen turning off.
|Re: Nexus 7 slow when less than 3GB free||ghost5||9/15/12 3:58 AM|
I will send mine off. Rooted but with stock Rom. 5gb off free space. At times it's almost unusable especially if apps are updating. I live in the UK.
|Re: Nexus 7 slow when less than 3GB free||terry082||9/15/12 10:53 AM|
I'm willing to send my laggy Nexus 7 for your investigation (if you don't mind my device being rooted)
I get the problem since day 2 after my purchase, when the free space is still 11GB...
I did factory reset as well as flashing the whole stock image for many many times. Each time would solve the problem temporarily for a day or two, then it lags again...
Really hopes it's just a software problem... not due to the use of crappy chips
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||9/15/12 2:37 PM|
If you don't mind UK shipping costs I'd be happy to send mine off. Would you want it wiped/ reset or "as is"?

So I've been wondering about the above. Just a very weird thing, and I started seeing some slowdown the week after putting a couple of movies on my N7 in preparation for a trip. Went into apps, and again, it showed about 2.5gb more storage used than was actually in use, then dropped down. I took a look at things, and it seems the discrepancy is cache files. In my case, over 2gb cache for Google Music, and over 300mb for Chrome. After deleting those, storage seems to report correctly, and my lag has greatly diminished, perhaps even gone (I guess it might be a place effect).
Maybe the way the N7 is reporting space that can be written to is being messed up by a large cache? Can someone else go through their apps and see if they can replicate my experience?

Yep, I've run into this "lag" problem as well. Filled up my device with movies, games with large games files, and syncing of JustReader and Currents for viewing content offline. Write speeds went in the toilet, and even after deleting much of this content and turning off Current and JustReader, write speeds never fully recovered. Did a Factory Reset, and back to butter-y goodness. Now making sure I don't exceed 8 GB of disk use, and turned off all syncing apps (like JustReader and Currents). Google/NVidia/ASUS, hope you come up with a software fix. My last tablet was a Samsung 8.9" with Honeycomb, and I never had this problem.

i would be willing to swap out now, especially if there are C9O units out there. a few people on the XDA forums have said their C9Os are much better than their initial C6O and C7Os. i've experienced massive slowdowns, and now my screen is lifting badly on the left.

Thanks to the many volunteers. I should have mentioned in my original request that we can only swap units purchased through the Google Play Store.

Ah, I bought mine at retail in the UK (HMV, for what it's worth). I'll have to sit this out until there's some kind of feedback about where this fault is coming from, and confirmation that if I swap for an newer unit it won't have the same problems. I've already had to take one back when the screen started coming off and I don't feel like spending an hour arguing the toss with the staff there just to wind up with another defective unit.

Paul, as I said above mine seems to be operating fine right now, although I did get some slowdown over the weekend that I was able to fix by clearing cache. But I'm still concerned given I need to manage my device to avoid seeing this slowdown. Will we hear from you here if it turns out this is a hardware issue that requires RMA and can't be fixed by a software update?

|Re: Nexus 7 slow when less than 3GB free||Dr. Digital||9/17/12 11:43 AM|
With the models that will be shipped back to Google, is there specific ways you want the tablet to be shipped back to you? Left in it's current state, FDR'ed/Stock, Current Rom/Kernel, etc? I am assuming that the devices will be wiped once they arrive anyways, or that this information would be present in the RMA e-mails that get sent once everything comes together.
|Re: Nexus 7 slow when less than 3GB free||amf101||9/17/12 2:29 PM|
As there is no external storage, are people not factoring in the space needed for the OS and cache? The SD card is virtual.
|Re: Nexus 7 slow when less than 3GB free||Paul||9/17/12 2:37 PM|
Good question GH0. We'd prefer it if you returned the devices as-is, in the middle of experiencing the problem, and with no screen lock. That will give us devices exactly as you're experiencing the issue to investigate. We will reset them after we're finished investigating.
We'll understand if you're uncomfortable sending us a device that's signed in to your account without the security features enabled. As an alternative, you could send us the tablet but first remove all of your accounts from Settings > Accounts.
If you're not comfortable with either of those options, you can factory data reset the tablet before sending it to us. I'm pretty sure that I've seen at least a few people comment that resetting permanently fixed the issue for them, so from a troubleshooting perspective resetting isn't ideal for the investigation.
|Re: Nexus 7 slow when less than 3GB free||Salty Wagyu||9/17/12 3:31 PM|
For those that are unable to send it back to Google for them to investigate (retail buyers for instance), could you try clearing out your app cache and see if this resolves the lag? Would recommend an app cache cleaner app to speed up the process as doing it manually for each app in the Applications menu could take a while!
Some of the folk over at XDA seem to think it helps, would test this myself but I already flashed a factory image and started over last week. Regardless, I've set it up to clean out my cache every 3 days from now on.
|Re: Nexus 7 slow when less than 3GB free||M.B.||9/17/12 4:00 PM|
I've cleared the cache and while it sped up some aspects of the tablet, overall it's still the laggiest Android device I've ever used at this point, when it used to be the speediest. Deleting apps, removing large media files, clearing cache and removing sync accounts doesn't put a dent in the slow writing speeds. Ever since I crossed an invisible storage threshold the tablet's performance has decreased considerably, and nothing I do to resolve the issue can bring it back to normal again.
I've got about 6GB available for internal storage at this point and I've cleared the cache for all my apps but it's still taking 10-30 seconds to open emails, load webpages, load the app drawer, etc. It's taking 4-5 minutes to start up after a shutdown, which is also taking noticeably longer than it used to. I can barely download apps at this point. It took about 5 minutes to even download a cache cleaning app to test out. My wifi signal is fine, a GNex using the same access point is able to DL at normal speed, and it was able to download the exact same app in seconds sitting next to the struggling 7.
I'm going to factory reset this evening after backing everything up, but while Paul mentions seeing people say that this "permanently" fixed the issue, that's not what I've seen on XDA and elsewhere. I've seen people posting that the issue returns as soon as they start filling up the full capacity of the tablet again, and many people are simply trying to avoid the "event horizon" storage threshold that lead to the lagginess in the first place, so they aren't pushing any boundaries to see if the symptoms return. I'll probably be in the second camp until an actual fix is found, but it's disappointing that my threshold seemed to be 4gb+ instead of 2-3 like most people's.
All I know is that my tablet has been flawless since purchase, and I had about 5gb to spare. Then I loaded approx. 800mb of songs (a single playlist) and immediately started encountering slow download times, apps taking 10-30 seconds to open, and restarts taking minutes more than they used to. That means just to be safe, after I reset I'm going to leave at least 6gb of internal storage free in order to avoid the lag. That's a real bummer because up until now my 7 was a flawless buttery speed machine. It made my GNex look absolutely slow in comparison. Now the GNex is running circles around the 7. And I need every inch of that 16gb, too, since I was moving from a tablet that had 32 and have already pared my media down, so not having access to that final 5-6gb 'just in case' it breaks the I/O again is a huge limitation.
Unfortunately I don't feel comfortable sending in a non-wiped tablet with any of my information on it, so right now I'm just taking the "reset and don't use the 7 to it's full potential" route. I hope some useful information comes from those with broken tablets who are willing to send them in.

I totally agree with you, quite a lot of us just passively avoiding putting too much information in the device just to avoid turning it into a useless brick.
Adding to that I have specifically tested the device after reset and re-flash by going beyond the so called 3GB limit (if there is such a specific limit), and I managed to reproduce the issue not just once but thrice on my device. While some might think they have got an I/O issue which might turn out to be something else so a reset helped permanently, but those who is suffering from I/O issue definitely need a better fix than constant reset, or take care not to fill up the tablet to a certain limit.
|Re: Nexus 7 slow when less than 3GB free||burnduck||9/17/12 4:19 PM|
The way i did that was to pin music from Google Music until it is full. It grinds the device to a halt everytime I do it, even after I cleared the cache of Google Music and rebooted the device.
|Re: Nexus 7 slow when less than 3GB free||kevmartin||9/17/12 4:28 PM|
Same issue here - glad to see Google is on it.
|Re: Nexus 7 slow when less than 3GB free||Siebes||9/17/12 7:34 PM|
I have the same issue on my Nexus 7 as well. Major slow down as soon as I filled it up with music. I've since deleted a bunch of the music, but it is still super sluggish.
Swiping sometimes doesn't work at all and I have to re-swipe a few times to get it to recognize.
Speed tests from speedtest.net are really slow and inconsistent and write speeds are poor via AndroBench.
I am going to try the factory reset tonight to see if I can get my tablet back in order.

|Re: Nexus 7 slow when less than 3GB free||waxsta||9/18/12 3:43 AM|
Ok. Just did a factory reset yesterday and added apps. Everything went super fast. I have performed two tests. One with 5GB free and another with 962MB free. I have attached my results. In short with 5 GB free after the reset the SW speeds were good around 10MB/s+ however with 962MB free SW is less than 1MB/s!
|Re: Nexus 7 slow when less than 3GB free||kevmartin||9/18/12 3:52 AM|
Can anyone suggest a way to do the factory reset without losing all the apps/settings/etc? I assumed a backup app would do the trick, but they seem to be pitched at devices that are rooted and/or have an SD Card to backup to.
I have not rooted my Nexus7 and have no desire to. And of course it doesn't have an SD card.
Any guidance would be appreciated. Thanks.
|Re: Nexus 7 slow when less than 3GB free||burnduck||9/18/12 4:11 AM|
I did a backup with the nexus toolkit software, which utilizes the backup feature in JB, mind you that can take a long time like more than 3 hours to backup then another 3 hours to restore.
|Re: Nexus 7 slow when less than 3GB free||kevmartin||9/18/12 4:59 AM|
Thanks. I thought the Nexus toolkit software roots the phone though. I really know nothing about the whole rooting thing and would prefer to avoid doing that at all costs. I just want my tablet to work properly and automatically get any updates that are released, and don't want to put time into any learning curve of rooting, custom roms, etc etc. If there is no other option I'll just reset it and lose settings etc - it's not that big a deal to set everything up again I guess.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||9/18/12 5:24 AM|
as burnduck said "Nexus Root Toolkit" doesnt need root to backup. You just need to read what the software tells you to do.
|Re: Nexus 7 slow when less than 3GB free||Psyclingeek||9/18/12 12:52 PM|
HI Paul -
I am willing to send my N7 in for repair/ analysis. For reference, I had loaded it up with app, photos, movies and had ~2.5GB free, the processing speed ground to a crawl routinely. I performed a factory reset last night, it is now lightly loaded and flying like brand new.
Hope that helps,
|Re: Nexus 7 slow when less than 3GB free||LEDominator||9/18/12 4:45 PM|
I have the same issue as well.
|Re: Nexus 7 slow when less than 3GB free||JGT||9/18/12 10:37 PM|
I reset mine after I saw that you had several volunteers. Then I got the emails for the return :-(
So, in the spirit of testing, I've loaded it up with podcasts, music, apps, and videos as before. No slow-down yet (nice to have it back the way I remember!). I'll see if I can get it to do a repeat, at which point I'll send it in, unless you still want it to have a look under the hood.
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/19/12 12:09 AM|
I can confirm that resetting does not permanently fix the issue.

When did you buy your tablet and if so, did you buy it online directly from Google? Maybe they fixed the problem and you've got a fresh tablet with the solution in it.
|Re: Nexus 7 slow when less than 3GB free||JGT||9/19/12 9:02 AM|
How long did it take to show up again? Mine has been loaded up for a day now without a hitch.

Also having this problem. Tablet is pretty much unusable.
Willing to trade or do any sort of debugging required to get this functional again.
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/19/12 9:38 AM|
Just got a replacement nexus 7 a few hours ago. Apparently this is the new batch, the serial number starts with C80K.
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||9/19/12 9:47 AM|
I got my Nexus 7 (16gb model) mid August. It was flying until this weekend when I went on my first plane trip with it. I loaded it up with music bringing it to 1.99 gigs free. It slowed to a crawl, VERY unresponsive even after hard reset. I deleted items until it was 5 gigs free, it's a LITTLE faster but still way slower than it was before I loaded it up, not near as nice to use, unimpressive performance. I had not brought it below 5 gigs free before the trip. If you need someone to send one in I will send mine along. I have not done a factory reset yet, was hoping a fix would come along so I would not have to reload apps, but would be happy to go ahead and send my Nexus in and reload the replacement tab to help get the problem fixed.
|Re: Nexus 7 slow when less than 3GB free||M.B.||9/19/12 10:37 AM|
I reset my tablet and so far all the symptoms of lag have disappeared, so it's at least back to normal temporarily until we get a more permanent fix. I've been slowly filling it up with content again and have about 7gb free at the moment with no issues. But I don't plan on dipping below 5-6 in order to avoid the slow speeds creeping up again. Waxsta mentioned that s/he has a C80K tablet that isn't exhibiting the symptoms even when almost completely full. Just to toss more info out there, my affected unit is a C70. It would be interesting to see if other people with C80 serials are immune to the I/O bug.

I have been testing my n7 quite vigorously and wanted to keep everyone informed of my findings.

We need people to confirm their Android version number to be absolutely sure. Model C80K Storage free 326MB Still running smooth. SW 5.81MB/s
|Re: Nexus 7 slow when less than 3GB free||scorpeeon||9/20/12 4:26 AM|
Just done 8 tests one after another and got pretty inconsistent results. I have around 4 GB of free storage at the moment but also had lower storage before.
The SEQ WR values int the 8 tests were: 0.8 MB/s, 7.11 MB/s, 10.23 MB/s, 3.02 MB/s, 0.52 MB/s, 10.31 MB/s, 0.51 MB/s, 2.93 MB/s.
Not quite sure if these results are normal.
Done the same test on my Galaxy S (GT-I9000) too (but it takes pretty long to complete there, at the beginning of test it even says that it's file system does not support DIRECT_IO so it will take long time, and it really does something called "purge buffer cache" before every test which lasts pretty long), there out of 4 tests i got these results for SEQ WR: 5.62 MB/s, 5.46 MB/s, 5.61 MB/s, 5.57 MB/s. These look like to be much more consistent.
I have 16 GB Nexus 7 running 4.1.1.
|Re: Nexus 7 slow when less than 3GB free||musicformymuse||9/20/12 5:55 AM|
hmm so the new nexus tablet with the serial numbers starting with C80K doesn't have the 'slow down' problem?
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/20/12 8:16 AM|
Noe. Some people have reported issues on the C80K too. I am trying to get more people to test without updating Anroid 4.1.1. I have a C80K on Android 4.1. There is a possibility that the update to the operating system causes the issue. However I have a hunch and just speculating based on my own experience so far. It would be good to get more people to test this and report back.
|Re: Nexus 7 slow when less than 3GB free||GarryH||9/20/12 11:53 AM|
I just did a test on my Nexus 7 which was bought last night with a serial code starting with C8OKBC. The remaining space is 1.2GB. AndroBench shows 20.34MB/S on read and 6.8MB/S on Write. The OS is 4.1.1 the latest one.
It seems this is a hardware issue on the pervious batches.
|Re: Nexus 7 slow when less than 3GB free||Dan Mile||9/20/12 5:13 PM|
I'll be happy to return mine as device is pretty much useless.
I started experiencing the slow down about a week ago - free space = 2.7GB.

|Re: Nexus 7 slow when less than 3GB free||phlegmish||9/21/12 5:10 AM|
The issue affects the Nexus 7 so everybody has version 4.1.
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/21/12 8:57 AM|
Google released an update to Android 4.1 at the time of the Nexus 7 release. As soon as people switched the device on for the first time they were/ are prompted to install the latest 'system update' after which the Android version becomes 4.1.1. I am on 4.1 and have been testing my tablet thoroughly. So far I have not experienced the slow down. This is my third Nexus 7, it has a different model number to my previous ones ( Serial number begins with C80K other two tablets that were faulty started with C70K).
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/21/12 9:34 AM|

Mine just started lagging after I installed the game Horn, which took me down below 5GB. I've uninstalled enough apps to take me above 7GB, but the lag remains. I'd be willing to send mine in, but I had to go through a few to get one with a good screen (good whites, no yellow tint, no dead pixels), and I'd hate to get stuck with a problematic unit. I'd be willing to send mine in after I can inspect the replacement to make sure it's as good as the one I have.
|Re: Nexus 7 slow when less than 3GB free||VesNL||9/21/12 2:40 PM|
For the people still offering their tablets up for "testing", please read Paul's post from a while back
Thanks to the many volunteers. I should have mentioned in my original request that we can only swap units purchased through the Google Play Store. I think we have more that enough volunteers, I'll pass your info over to my colleagues in the Google Play Store and they'll reach out to a few of the volunteers.

I have a 16 gigabyte Nexus as well. mine has started running on godly slow when I reach down to 1 gigabyte of free flash. I'm a little ticked off that its running so slow. I'm thinking this is a hardware defect and a major recall is in order. I just did a andro benchmark and I have very similar memory performance scores. This sucks...

|Re: Nexus 7 slow when less than 3GB free||HaiColon||9/25/12 12:50 AM|
It might take a long time for Google to fix this. They still haven't even fixed the screen flicker (in low brightness) problem and that's been reported months ago with people being told to send in their device just to get a replacement with the same problem or in some cases worse. So for now, I think you should really consider doing a factory reset instead of waiting. It's very quick and easy, the downside is that you loose all of your data, so make a backup first if you need to. I did a factory reset and my tablet is fast again. I don't think it completely solves the problem because the random write speeds are still a bit low according to AndroBench, but the tablet is noticeably faster and usable again.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||9/25/12 9:39 AM|
I wonder if a custom ROM alleviates the problem? Like using CM10?
I didn't want to lose my warranty to try it so I'm still on stock.
I called up Asus and they gave me the spiel that when you get low on space things slow down. They said its the same thing as a computer would do if low on space. I told them that on a PC you can delete some data and that fixes the issue. However I told them even when I free up space on the N7 it makes no impact. They seemed a bit perplexed by this. The last thing they told me to do was go into apps and clear the browser caches. I already did a factory reset so that won't help. Next time my N7 runs slow again I told them I will try it. I told them I feel uneasy about loading down my tablet again to try.will see. So far my nexus remains at 8gb free no slowdown yet. I hope this issue gets resolved because the 8gb users aren't having this issue. This leads me to a hardware issue on the 16gb platform. :-(
|Re: Nexus 7 slow when less than 3GB free||McChen||9/25/12 4:43 PM|
I am also having this same problem with my 16gb nexus 7. I loaded a bunch of movies and dipped below 1.5GB free space and the lag was horrible. I freed up space, now 5.5GB free, but the lag remains. I will probably have to factory reset it at some point, it's almost unusable.
I think the problem is likely that TRIM is broken, so when all the blocks are written, write operations have to then erase the block before writing, taking a very long time. Rather than having 'pre-erased' blocks that a TRIM background process would provide. If this is the case, then there is no specific space limit that people must keep free and it is a matter of time before this affects everyone. If you copy lots of big files like movies, you will dirty up the blocks much faster. But even if you don't, general use of the tablet will create dirty blocks as you browse the web, etc. It may take longer, but eventually all the blocks will become dirty. This may be why people are seeing this at different points.
The question is whether this is a hardware or software issue. Hopefully it is just a software issue with the trimming process. Worst case, it would be a hardware limitation with the flash storage, where either TRIM is broken or even worse ,TRIM was never implemented in the first place. I remember some of the early SSDs did not support TRIM in the hardware and neither did XP and eventually the drive and OS would become very laggy much like what we are seeing here. I can't imagine people are making SSDs or flash without TRIM support these days.
The earlier poster who rolled back to 4.1 and didn't see the issue is possibly a sign that it is a software issue. Perhaps they could upgrade to 4.1.1 as a test to see if the issue comes back?
|Re: Nexus 7 slow when less than 3GB free||Liang Sun||9/26/12 9:49 AM|
You idea is very good!
I have updated my Nexus 7 at the very time when I received it.
And I am also having this same problem.
The SEQ WR decreased to 0.4 when the storage was below 3GB.
As someone said that this problem may be caused by the Android 4.1.1 update, I try to rollback my Nexus 7 to 4.1
Below is the Androbench test results:
SEQ RD 23.83 MB/s

|Re: Nexus 7 slow when less than 3GB free||Liang Sun||9/26/12 10:03 AM|
Then I found something interesting:
I turn off my Nexus 7 and turn on it 10 min later.
And I have test with Androbench for 5 times
Here are the results (only SEQ WR)
SEQ WR 2.27 MB/s
SEQ WR 2.44 MB/s
SEQ WR 11.63 MB/s
SEQ WR 5.41 MB/s
SEQ WR 8.40 MB/s
So I think the TRIM has done its work on the background in Android 4.1
And I do not feel the system response is slow.
So my be a Temporary solutions can be rollback the Nexus 7 to Android 4.1.
The Factory image is JRN84D.
The Factory image of Android 4.1.1 is JRO03D.
I hope my tests can help you to deeper your understanding of this problem.
|Re: Nexus 7 slow when less than 3GB free||McChen||9/26/12 3:59 PM|
thanks liang for the report....it matches up with what another poster was saying....4.1 is OK, but 4.1.1 is broken (TRIM function most likely). things are starting to point to a software issue, which is better than having a hardware issue I suppose. sounds like a software regression bug. you would think something like this would be caught in QA stress testing.
How did you rollback to 4.1? The Google Developers page only provides the 4.1.1 factory image, I can't find 4.1
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||9/26/12 4:55 PM|
Yeah how do you rollback to 4.1? Id like to know too.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||9/27/12 1:24 AM|
This is the 4.1 Nexus 7 Factory Image, I checked MD5 and the codes matches.
Here's another one http://d-h.st/Gja from dev-host
I wont explain how to do it here, there are lot of howto and remember that factory images wipe everything.
Im sure there are some roms in xda with 4.1, maybe a stock one too to be flashed with cwm
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/27/12 7:35 AM|
I believe the person that many people are referring to might be me. I will tell my story again from the beginning for the benefit of people who haven't had a chance to read my original post/ posts.
I am now on my 3rd Nexus 7 Tablet.
Tablet 1: Serial number beginning C70K
I originally bought my first Nexus Tablet about a month ago. It worked like a dream. Fast responsive speeds with nothing to complain about expect the dodgy looking screen lift issue that I ignored for about a week. Anyway the moment I first booted it up I was prompted with a system update message to upgrade to Android 4.1.1. I thought since they have just launched the device this update must have critical host critical updates. So I blindly updated which was painless and relatively fast. For the week I had it, it was great. Then I started to load fill it up with movies and lots of games. Eventually it started to slow down. At this point I didn't know about bench marking the storage so I didn't perform any kinds of tests. However after a week of light usage it started becoming quite obvious that the screen wanted to separate from the rest of the device and live a life of independence. So I decided that I would return the device and get a replacement since the tablet is so damn cool.
Tablet 2: Serial number beginning C70K
After inspecting the new tablet and being relatively happy with the screen (although I did notice a slight screen lift) I decided that I wasn't going to be too picky if the screen remained the way it was when I first opened the box. Again upon first booting up the device I was prompted to perform a system update, so I happily pressed Install. So here I am happily skipping along getting comfortable with my brand spanking new tablet and continued to install lots of games and movies onto it. About a few days into having this new tablet I started to notice SERIOUS lag, and I mean SERIOUS. Gestures would not register correctly, apps would load very slowly and even the desktop icons would sometimes take time to appear! After reading up online I realised that this was a common issue that many people were experiencing. I then stumbled upon androbench. After performing a few runs on the tool it became obvious that the issue was the sequential writing speeds that had fallen around 0.5MB/ s. I then set out to perform thorough tests varying the remaining storage space and recording the test results. I could not get my device back to normal speeds even after removing almost everything. In the end I decided to do a factory reset to see if it would resolve the issue, however in the back of my mind this was a nonsensical solution since if I would have to maintain a 3GB buffer for the operating system to use for paging I virtually had an 8GB device given the fact that a few GB are already taken up by the operating system itself. So after the factory reset speeds were better, however not optimum. Again I tested the device by filling it up again and once again I was in the dilemma of sluggish performance. I reset the device back to factory defaults and returned it to the store.
Tablet 3: Serial number beginning C80K
So I went back to the store to return my 2nd Nexus, promising myself that I would give it back and wait for something better to come out like the iPad mini although if rumours hold true the resolution will be rubbish. During my conversation with the sales person at the store I was informed that many people had been returning these for similar reasons. In the end I started having second thoughts, "maybe there is a good batch out there". So I asked the sales staff to check their stock for a new device once again. He came back from the stock room with a box that had the serial number C80K... So I took a deep breathe and thought I will try this one for the last time before finally giving up. I took the chance and rushed off home. My first observation upon opening the box was that the screen was fixed completely flush against the side bezel identically on both sides of the tablet, surely this was a good sign and different to both of my previous tablets. So I booted the device up for the first time (well third technically) and was presented once again with the system update prompt. I decided to ignore the prompt until I had tested the device very very thoroughly. So I filled it up from the very beginning with just movies, combination of photos files and movies, apps...etc. The device ran flawlessly in every scenario! Write speeds were never under 1MB/s, and the tablet ran (and still runs) beautifully.
I currently have less than a GB free and I get an average of 8MB/s sequential write speeds. I have attached my benchmark screenshots to this post. I have many many results stored in the Androbench app itself but do not know how to access them (taking screenshots is very long considering the fact that I have over 30 test results).
So my personal observation is that the culprit is most likely the Android 4.1.1 system update. However I have yet to see more people provide test results that have not yet fallen into the trap of updating immediately after booting up the device for the first time. Seeing the severity of the issue first hand I must say this issue must be resolved immediately. The way I see it, resolving this issue is basically the difference between the Nexus 7 being a big paperweight to a real competitor in the 7 inch Tablet market space.

I truly hope it is the 4.1.1 update. Then that can easily be resolved. I had to exchange my device 3 times to Walmart because of the screen lift issue, it was a stressful ordeal and very disappointing to have to exchange it 3 times for that defect.
All my devices did have the immediate 4.1.1 update and I did all of them. All the devices I exchanged are C60 models. I never knew about the slowdown until about a month ago. Apps would stop responding and was getting really laggy. I heard about a slowdown issue and did the androbench, sure enough I get the same scores as everyone else. Don't get me wrong, I love this tablet. I'm just a bit upset with the quality control issues. If I was going to launch a first time product and make an impressive device that trumps all others in its class I would rigorously test it to be sure it is flawless befor launch.

thanks for the 4.1 image link....i am seriously considering rolling back to see if it helps as my tablet as it is nearly unusable at times, it's a horrible experience. when i first got my tablet it was ripping fast, now it is a device that i hate to use. i hope google pushes out a fix quickly for this, i'd hate to see this issue drag out. this is not really the nexus experience that I anticipated and i'm waiting to see how well google support responds. if the nexus brand is to mean anything, google really must go above and beyond in listening to customer issues and responding quickly.
waxsta....has the nexus 7 been stable on 4.1? and has it forced you to upgrade to 4.1.1 at any point? i remember some android firmwares would not let you put off system upgrades indefinitely, at some point it would automatically install.
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/27/12 12:31 PM|
Android 4.1 has been perfectly stable. I haven't been forced to update of course but I do get regular reminders to upgrade every now and then which are pretty annoying. Apparently to disable the notification you have to root your tablet, which is something that I want to avoid doing for now. So in short the answer to your question is I always get an option that says update later which I select and am not reminded to update for about 5 minutes or until I lock the tablet.

No problem at all Freedom ITA I'm just glad I can provide some guidance on an issue that I also suffered from.
@McChen I have attached a screen shot of the system update prompt.

Custom rom doesn't help. Running cm10 and have too keep free space above 5gig or else.
|Re: Nexus 7 slow when less than 3GB free||burnduck||9/27/12 4:02 PM|
Do you think you'll ever be updating to 4.1.1 on your C80K just to scientifically prove it's got something to do with the OS update?
|Re: Nexus 7 slow when less than 3GB free||BoomAM||9/27/12 10:48 PM|
Unfortunately I have the problem too, I checked the same thing on my Galaxy Nexus and the problem exists on that too, in regards to IO write issues, the problem isn't as severe though so in usage it still feels perfectly fine.
Both running 4.1.1
Does anyone know if this new F firmware that's on some devices fixes it? Is it even available as an OTA?
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/27/12 11:46 PM|
I did think about it but I don't know how to downgrade so until do some research into it I will not be updating.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||9/28/12 1:22 AM|
Downgraded to 4.1 and filling the baby with some food...
mainly MB :) Ill let you guys know something sometime
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||9/28/12 2:01 AM|
That cm10 version you've used, is it based on 4.1.1?
|Re: Nexus 7 slow when less than 3GB free||A.Marosvolgyi||9/28/12 2:06 AM|
i just did the same. back to 4.1
mine is C8O series, sot it exists on this serial too.
i'll keep everyone posted.
|Re: Nexus 7 slow when less than 3GB free||andybak||9/28/12 5:42 AM|
Just had this infuriating email from 'Audrey' on the Google Play support team a week after explaining the issue carefully and pointing them at this discussion:
"It sounds like you're having an issue with the functionality of the device when the space gets down to 3GB. This is the first we've heard of this issue. It is not a known issue."
She didn't even seem to acknowledge the existance of this thread or the participation of a Google staff member in it. And that reply took a week! I feel quite angry...
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/28/12 6:56 AM|
A.Marosvolgyi and FreedomITA
How did you downgrade? Do you have a step by step guide? I am just curious in case I feel adventurous in the future and am willing to risk updating.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||9/28/12 7:47 AM|
There is a good tool to downgrade, but remember that it wipes everything ( "sd" too).
There are two ways for flashing the 4.1 factory image (I have posted the link before).
1. Fastboot there is a howto on google developers site https://developers.google.com/android/nexus/images
Its a lil bit tricky not so difficult but... depends on you. You have to use cmd.
2. Nexus Root Toolkit 1.5.3 so you can first install drivers,change your model type (model of the device and the rom you have)
Then use the "Flash Stock" button, then flag "Other/Browse,,,," and "I downloaded a factory image myself that I would like to use instead" too.
Press ok and then browse on ur desktop the factory image.... then follow instructions.
Charge your nexus 7 and follow every single step reading everything... dont press ok ok ok ok ok enter enter enter...

|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||9/28/12 9:13 AM|
Wow! That sucks! Looks like the ol'
"Deny it even if it's true" spiel. Sounds like they know about it but don't want to get into a costly way to fix the issue? (Assuming its related to a hardware issue that pops up in 4.1.1)
|Re: Nexus 7 slow when less than 3GB free||A.Marosvolgyi||9/28/12 9:46 AM|
yeah i wrote one today to XDA, the LAG thrad, here it comes.
My device(16GB) is just one week old, i got it from argos/london. Its serial starting with C8O, so its still present at newer series too.
The "lag issue" was started two days ago, internal storage free space accidently dropped under 1GB. Deleting things did not work in my case.
Looks like its a TRIM related software bug in 4.1.1,
Here is what i've done to repair it(hopefully it will be okay until they repair the issue.
ATTENTION! Follow this guide your own risk, I am in no way responsible for anything you do to your tablet period.
1.Backup, backup, backup!
2.Download/unzip stock 4.1 from here: http://www.android-advice.com/file-d...y-8b0bd791.tgz or http://d-h.st/Gja (thanks for the links to FreedomITA
3.Download/install android SDK from here: http://www.google.hu/url?sa=t&rct=j&...Q8wQiLzoOFdGlg
4.Follow this guide, dont forget to hit the thanks button! When you reach step 6, watch change the .zip name to your actual zip! http://forum.xda-developers.com/show....php?t=1781250
5.Root with this (rooting with toolbox v2.0 not sure its a good idea, because its made for 4.1.1)
Looks like in 4.1 the issue is not present, but i'm not 100% sure.
Dont update to 4.1.1! The updater will bother you pretty often, but simply click to install it later.
Hope this helps.

|Re: Nexus 7 slow when less than 3GB free||Shitiz Garg||9/29/12 6:06 AM|
I was wondering, is there any disadvantages of 4.1 when compared to 4.1.1? As in did you feel its performance was worse (when your 4.1.1 was mint and working without any I/O lags)?
|Re: Nexus 7 slow when less than 3GB free||A.Marosvolgyi||9/29/12 6:15 AM|
i really dont, i dont even know what they did in 4.1.1 compare to 4.1 :)
|Re: Nexus 7 slow when less than 3GB free||waxsta||9/29/12 2:45 PM|
The release in formation seems very vague. However I do recall that sequential write performance was better in 4.1.1 when running benchmarks, however that advantage becomes obsolete when you factor in the slow performance issues.
I have attached the information that comes up when you select more details following the system update prompt.

Nexus 7 limited warranty
The Nexus 7 is manufactured by ASUSTeK Computer Inc. ASUS provides a limited 12 month warranty for the Nexus 7. Please refer to the warranty card in the Nexus 7 packaging or review ASUS' limited warranty details.

Give them a break, those answering your call probably don't even have a nexus 7 themselves so wouldn't have read this support forum, before the engineering has done this investigation and come back as official they have to be really careful with what they say.
|Re: Nexus 7 slow when less than 3GB free||Erica Renee Miller||9/30/12 8:00 AM|
Hey Paul from google why dont you be useful and help me get a phone number or email address from someone at google with the ability to help me . I bought and paid for two google nexus tablets had to send them both back.. GOOGLE AS MY TABLETS AND MONEY AND ARE NOWTelling me to go AWAY..!!!!!!!!!! i HAVE SENT many emails and talked to the useless people at the google play support by phone they all say if i could help i would but your CASE IS CLOSED.. THEN HANG UP ON ME..
what does all this mean.. case closed and to go away .. wtf
My google experience
I pre ordered the google nexus 7 on the day the went on sale. One week after they started shipping i sent google a email asking them when mine would ship. I was told within a week. Two weeks later i call them to see what is up. As at this point my account was charged for the device. They tell me shipping any day. Two days later i see on my wallet account as google nexus 16 gb ORDER CANCELED BY SELLER.
So i call google back and ask what is up. they said it was a computer issue. And that i would have to reorder. At this time they where backorderd for up to 4-6 weeks on the 8 gb . OUT OF STOCK ON 16. So i ordered the 8 gb version. After a week i received it. Two weeks later i start seeing lines on the screen when you hold it on the left side of the screen as well as the screen moving.
I CALL GOOGLE BACK . they tell me that I can send it back and DO A advance replacmeent exchange. I tell them im not having my money put on hold. I will send it back in a few weeks and just reorder another device when they receive it.
So i decided to just order the device and send this back into them when i receive the new device. .
Its now the end of Aug the new device comes in the mail . It comes in with a CRACKED SCREEN . SO not 30 minutes after usp drops the device off i call GOOGLE YET AGAIN. TO GET A RMA for the brand new replacement device. I GET THAT JUST FINE.Send google this device that i only had for 30 minutes in my posession. still at this time holding on the original device as its still working . you just cant push on the left side of screen. GOOGLE Recieved the device on the 5th of september. Since then i have had several phone calls and exchange of emails. Being told that the device i sent them back was the original device and they WOULD NOT ISSUE A REFUND OR REPLACE THE DEVICE. STATING THAT i would have to prove what device i sent in. They have it so i have no way of doing so . Other then they can see what device is being used and connected to my google wallet. They understand and can see this so im told. But still refuse to help me in any way. So now today on 9/27 I contact them for the last time and demand i get a RMA to send the original device back to them as proof that it was not the one they keep saying they have. SO NOW GOOGLE HAS ALL OF MY MONEY BOTH OF MY DEVICES . AND COULD CARE LESS ABOUT ME AS A CUSTOMER
|Re: Nexus 7 slow when less than 3GB free||WebmastuhB||9/30/12 6:34 PM|
I am in no way affiliated with Google, but I sense your anger. I've been in similar, frustrating situations with other companies. Here's what I would do if I were you.
Document everything in a well crafted letter. Use short, easy to read bullet points. Avoid grammatical & spelling mistakes. Keep emotion out of it, no one cares. Eliminate "diarrhea of the pen" and keep the letter short and to the point.
You have a point to make - you paid for two Nexus tablets, and you don't have them. Don't add in a lot of crap that muddles this point - none of that stuff matters. Talk about when you were first charged for tablet 1; be explicit about the date. Mention when you received tablet 1, what happened when you opened the box, why it was a problem, who you talked to, and how and when you returned it. Mention specifically when you were charged again, and when you received tablet 2, and what you did from that point. Mention each time you talked with customer support and what was said.
Be clear at the end of the letter as to what you want (ie. refund both charges/refund one charge, send me a new tablet/etc).
Post the letter on a blog (with sensitive information blocked out). Email the letter to customer support. Post the letter here. Print the letter on nice paper, sign it, send it to people at Google using snail mail. Wait for a response. Give it some legitimate time.
If you fail to get an adequate response, you could go to Gizmodo/Reddit/The Consumerist/other tech forums and places like that and make sure they are aware of your issues. You could also find some specific forums somewhere filled with people who already hate Google/Android and you could post copies of the letter there.
Make another attempt to contact Google via email or phone. Document all of this.
If you fail to receive an adequate response, you should call your bank and have the charges removed. After all, you were charged for two tablets, and you do not have them, correct? If this is the case, and Google has failed to rectify the situation, and you can document all of it, your bank will not charge you.
My guess is Google will correct this problem long before this point. After all, the cost of two tablets is nothing to them. Cut them some slack - they are a search engine company and rarely sell actual tangible products. Its new turf for them, they are bound to make a few goofs.
|Re: Nexus 7 slow when less than 3GB free||garpunkal||10/1/12 12:11 AM|

|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/1/12 8:28 AM|
....no idea guys.... when I was with 4.1.1 with less then 1.5 gb free the N7 became unusable, trust me and Google please read this:
unusable, I couldnt even write an email cause the keyboard was laggy. I tried to flash a rom over without freeing the space. No go.
Factory resetted the N7....good, finally, everything was ok (I remember that the reset cleans everything)
Then Ive decided to downgrade to 4.1, and I started to fill the space with everything...
1 gb left everything looks good! Let's go further...
...until N7 wrote me: free space is ending (500 mb)
ok Lets bench:
Seq wr: 0.42 mb ....ouch... BUT the N7 was not bad as the first time, I can do quite everything, apps take 2/3 seconds to start
Seq wr: 8.3 mb what?
another one... mmm random writing stuck... ok:
0.72 et cetera-
But the device is not "slow".
No idea guys... the first thing is to suggest to change the benchmark software. Does antutu has a test for our problem?
|Re: Nexus 7 slow when less than 3GB free||Dr. Digital||10/1/12 8:33 AM|
I was wondering what the rma policy is for these devices we recieved are? I woke up to the replacement tablet doing some odd things and then attempted to try to find any deadspots because I was having some issues with some games recognizing my finger.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/1/12 9:45 AM|
The "marked as complete" is really an artifact of how these forums work, garpunkal. We know this issue is still evident out there and we're still working on it.
On long forum threads like this I've found it helpful to put the most recent important information right at the beginning of the thread where newcomers can find it quickly -- that way they don't have to dig through a bunch of replies looking for official updates. The only method I have available of pinning a reply at the beginning of a thread is to mark it as complete. Please be assured that I'll update this thread and pin that update when there's important new information.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/1/12 9:49 AM|
GH0 you can contact Google Play directly to let them know about the issue you're experiencing. If they indicate that your tablet should be replaced they can send you a replacement. Replacement tablets are sent in advance of you returning a device with a problem so you're never without a tablet.
If I may ask a favor, I'd appreciate it if you help keep this thread on-topic about the issue with slow performance when running low on memory. There are a lot of people on this thread that are only interested in that issue and I'd prefer to not let this topic drift. Thank you.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/1/12 11:00 AM|

|Re: Nexus 7 slow when less than 3GB free||Dr. Digital||10/1/12 12:35 PM|
Sorry I should have been more clear. This was a question about the device that I received as a replacement for the device that I sent to Google about this issue. Which is why I asked here. Sorry about that.

GH0 thanks for clarifying. Do you mean you received a replacement device and it has touch input issues? Bummer! If you contact the Google Play team they should be able to assist you with an RMA for that device.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/1/12 1:12 PM|
I believe this has been reliably reproduced on at least one tablet by the team, rob0t, which is very helpful to the investigation.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/1/12 1:14 PM|

I have been following this thread since it began and I have brought a Nexus 7 (C80 series) from Argos here in the UK.
i love the device but am afraid to fill the memory due to the conversation in this thread, do we know if this would be a hardware or software related error as of yet and if hardware should we be sending our devices fro replacement to ASUS?

4.1, 1 day of Testing No go.
Downgrading doesn't help, issue is still present
Not as bad as 4.1.1 but the lag and unresponsiveness is evident
|Re: Nexus 7 slow when less than 3GB free||waxsta||10/2/12 5:08 AM|
Could you post your Androbench benchmark results?
Could you also give an example of the lag? E.g. steps to reproduce a persistent issue?
|Re: Nexus 7 slow when less than 3GB free||waxsta||10/2/12 5:10 AM|
Here are my results after having 1.91 GB free.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/2/12 7:27 AM|
4.1.1 lag was huge: example? Writing an email or text, 1) I write an entire word, 2) Nexus 7 shows me the first letter than it stucks and when I have finished writing the second word it writes in one shot the first and the second word.
4.1 not that bad it just take some time to load an app or open an app. Much better...
Now Ill show you 3 benches with 2 giga left... (I had 500 mb and then I delet something) on 4.1
Thats strange... I think androbench doesnt like my N7....too different values.
Antutu gives me similar scores.
Updating to 4.1.1
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/2/12 7:40 AM|
4.1.1 nothing changed.... everything is quite smooth. Bench gives me high and low scores.
I couldnt replicate the same lag as the first time.
I can just say that the first time I turned on my N7 updated to 4.1.1 filled with games and apps and the problem appeared and it was a big problem.
Tried to start with 4.1 and filling with gb, everything was "quite smooth" not superspeed as always but not that bad (take some sec to start apps and sometime a lil lag)
Upgraded to 4.1.1 not bad
|Re: Nexus 7 slow when less than 3GB free||AsgardTech||10/2/12 8:26 AM|
Sorry for my English (Google Translate). I am Russian
Which found no solution to the problem with the brakes card.
In the first set 4.1. In 4.1.1 when there is less than 3 GB of memory terrible brakes. In 4.1 but there is no such rate jumps from 0.1mb \ s to 10Mb \ s
The second we get root, put a custom recovery.
Third flash custom kernel that's http://rootzwiki.com/topic/31344-kernel011ap33160ghz-quaduvcifsutf-8powerhallinux-3x-hybridsep-25/ (there by default Block I / O: Deadline, no permanent relief to the memory card that is e off fsync). I flash [CFS] (Mainline Edition Max@1.4 GHz Quad, GPU @ 512 MHz). Moderate acceleration to 1.4Gtsa.
In the end, the system works fine even when crowded the entire memory. It does not solve the problem of hardware, if you can change the warranty I advise to do so. But for those who bought in the hope ebey useful.
Myself until I test, scored the eyeballs all about. Deleted again scored. Everything is OK. Applications are running smoothly, the desktop of a miracle does not brake when the orientation. I want to drive on a torrent and loaded fs ....

|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/2/12 11:30 AM|
Ok since reverting to 4.1 doesnt fix it, I think its safe to say its a hardware issue. Next step: Recall on Nexus 7 16GB. Don't know why the 8GB units are free of this issue.
It's up to Google/Asus now to man up and fix it. I hope they take care of us and do the right thing.

I don't think it effects all N7 devices, just a lot of them. I did a factory reset for the third time since owning my N7 last night due to lag and I had more than 7 GB remaining.
I was offered to replace through warranty but don't want to go through the process if all devices suffer from this issue.

|Re: Nexus 7 slow when less than 3GB free||waxsta||10/2/12 2:29 PM|
I believe the 8GB Nexus has different flash memory I think it is Kingston where as the 16GB memory from a different manufacturer. I will try to find some links to back up my claim.
|Re: Nexus 7 slow when less than 3GB free||Felipe Ortega||10/2/12 2:40 PM|
It does, Anandtech had a write up. I purchased a 8GB model to test. I may have to dump the 16GB. Which is a shame.
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/2/12 2:55 PM|
I just called support for two issues. One of the issues was this slow down business. I was told that Google is aware of it and is working on it, and that Jelly Bean 4.1.6 is being rolled out on Oct. 6th to address this issue as well as other issues.
My other issue is that my credit card has not been refunded for a Nexus 7 I refused shipment on from the original June time frame. WTF? Support was very helpful this time, but Google seems to need a little practice in this line! LOL!
|Re: Nexus 7 slow when less than 3GB free||Micah Stewart||10/2/12 3:12 PM|
That's weird because it makes it sound like all 16GB devices are affected when support specifically told me that wasn't the case.
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/2/12 3:20 PM|
Does anyone know for certain what exactly is going on? An update may target only affected devices, and some or all might be affected. But the Google support guy knowing about it and about a scheduled update to address it is awesome news as I am getting quite frustrated with using the tablet. I didn't want to do a refresh if possible so will try and hold off as long as possible.

What kind of flash memory is in the 16 GB anyways? Mabey its the cheaper MLC memory that's slower and inferior to SLC type. Mabey the 8GB Nexus 7 uses expensive SLC Kingston flash chips and the 16GB version uses the junky cheaper slow MLC chips? If so we got jipped. I hope not.....
|Re: Nexus 7 slow when less than 3GB free||Nicholas Burress||10/3/12 12:00 AM|
I thought I'd chime in saying I'm having the same issue. Hopefully, the new software will fix the issue. Can we confirm the release of 4.1.6?
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/3/12 1:53 AM|
@mjflynt really? who told you about the 4.1.6 and the oct 6th date? Thats an awesome news
|Re: Nexus 7 slow when less than 3GB free||oneofbillions||10/3/12 5:03 AM|
That awesome 25cent sale has caused my Nexus 7 16GB model to also slow to a crawl. Just adding my voice ;)
|Re: Nexus 7 slow when less than 3GB free||Benjo_1||10/3/12 9:24 AM|
It appears the problem for many people may be linked to Google Currents. My 16gb model had also been suffering from slowdown for similar reasons to what was posted on this thread. After identifying that the error was related to the read/write speeds I did some searches for potential fixes and managed to find this on youtube;
For me all it took to fix the problem was to disable background syncs in Google Currents (as shown in the video) and even without rebooting my Nexus 7 is currently showing the same read/write speeds as new devices and is much more responsive.
|Re: Nexus 7 slow when less than 3GB free||Nicholas Burress||10/3/12 10:05 AM|
Is your storage below 3GB with the same results???
|Re: Nexus 7 slow when less than 3GB free||burnduck||10/3/12 10:19 AM|
Current might have made it worse by syncing and queueing to writing to the eMMC, but the cause behind it is down to the slow write speed when the storage is almost full
|Re: Nexus 7 slow when less than 3GB free||burnduck||10/3/12 10:22 AM|
I believe it's some kind of eMMC package? It's even printed on the outside on my Nexus 7 box on the specs sticker. (16GB EMMC)
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/3/12 10:36 PM|
A Google support guy named Dennis.
|Re: Nexus 7 slow when less than 3GB free||David Combes||10/4/12 1:31 AM|
I also have this problem. Totally stock tablet, not rooted or flashed. I think it affects all tablets, it's just a gradual degradation in performance that only really becomes noticeable when it gets really bad.
My storage went below perhaps 2 gig when I installed a large app (Horn). It's since been very unresponsive, often reporting apps as unresponsive. I tested with Androbench, and found my speeds were at the bottom end of those reported (SEQ WR 0.38 MB/s, RND WR 15.17 IOPS).
It's not great, and I really don't want to have to start setting it up all over again. I would really love an over the air update to make the problem go away.
|Re: Nexus 7 slow when less than 3GB free||MiscFiles||10/4/12 3:16 AM|
I am having the same problem as others have reported since installing a couple of large games (Dark Knight Returns and Horn) on my stock, unrooted 16GB Nexus 7. The device feels extremely sluggish, misses touch gestures, shows Force Close / Wait dialogs, and takes much longer than usual to start up. Many games are now unplayable.
AndroBench gives me the following:
I bought the Nexus 7 after using a cheap Arnova 10 G2 because I wanted THE Google tablet. I was highly impressed at first, but the device is borderline unusable in its current state. Very disappointing. I hope Google/Asus can either rectify the problem in software or replace my tablet with one that works properly.
|Re: Nexus 7 slow when less than 3GB free||Benjo_1||10/4/12 4:54 AM|
Yes my storage is currently at 2.96gb and my read/write speeds are back to normal. I haven't tested if the issue will re-occur but for me simply turning off background syncs in google currents cleared everything up right away.
For the record prior to doing the Google Currents fix my results under Androbench were as follows;
SEQ RD 13.4 MB/s
SEQ WR: 0.5 MB/s
RND RD: 1494.39 IOPS(4K)
RNG WR; 59.03 IOPS (4K)
Immediately after turning of background syncs I got;
SEQ RD 27.53 MB/s
SEQ WR: 5.7 MB/s
RND RD: 1899.02 IOPS(4K)
RNG WR; 38.06 IOPS (4K)
|Re: Nexus 7 slow when less than 3GB free||CharlieKF||10/4/12 5:43 AM|
Having the same issue as others. Have turned off background synching of Currents and will see what happens... and hoping for the 4.1.6 update this week to resolve the issue fully.
This is basically a "me too," I guess, but wanted to add my voice to the chorus to allow Google to get a sense of how many folks there are having issues.
|Re: Nexus 7 slow when less than 3GB free||762x51||10/4/12 6:24 AM|
I too have this seriously annoying issue. All started after letting my free space drop to under 3gb. Unfortunately, I cannot seem to get performance back no matter what I do. I have done a factory reset, wiped internal storage, wiped cache and dalvik in recovery, and completely set up the tablet again with minimal apps. Still the issue persists. Wondering if I should just RMA at this point.....
|Re: Nexus 7 slow when less than 3GB free||backlund||10/4/12 9:41 AM|
I too have had this happen on 16GB N7. I have fixed it twice by factory resetting, reinstalling, etc. Last night it hit my device for the 3rd time, but this time I still have over 8GB of space free. WTF?!?! I rebooted multiple times, cleared all caches, but nothing helps. Looks like I'm going to be doing my 3rd full reset again. I'm not sure what Google's official stance is on rooting, etc., but if it wasn't for Titanium Backup, I would have sold or returned my N7 due to having to factory reset the device this many times and losing game data, etc.
I really hope that Oct. 6th - 4.1.6 comment is true, but doesn't it seem a bit odd that an update would release on a Saturday?
|Re: Nexus 7 slow when less than 3GB free||Nassor||10/4/12 10:30 AM|
Same problem here. Disabling background sync in Currents & making sure i have at least 3GB of free space helped, but performance is still not as good as before.
|Re: Nexus 7 slow when less than 3GB free||DigitalPic||10/4/12 10:41 AM|
I did this as well and noticed *some* improvement, but nowhere near what it originally was... i hope an OTA will indeed fix this.
|Re: Nexus 7 slow when less than 3GB free||MiscFiles||10/4/12 12:59 PM|
I've just switched off background sync in Currents, cleared caches and uninstalled Horn and a couple of other apps I don't use. I now have 4.63GB remaining. After rebooting, I ran AndroBench and got even worse figures than before:
Sequential Read: 2.13 MB/s
Sequential Write: 0.08 MB/s
Random Read: 0.26 MB/s, 67.72 IOPS(4K)
Random Write: 0.01 MB/s, 4.33 IOPS(4K)
SQLite Insert: 2.44 TPS, 122.87 sec
SQLite Update: 2.23 TPS, 134.37 sec
SQLite Delete: 2.07 TPS, 144.7 sec
|Re: Nexus 7 slow when less than 3GB free||daern||10/5/12 3:16 AM|
Sorry, but another "me too": 4.1.1, filled to < 1GB free. Virtually unusable now. Waiting for the (hoped for) release this weekend and if not got by Sunday, will factory reset.
Anyone heard any more news about possible fix rollout schedule?
|Re: Nexus 7 slow when less than 3GB free||pouyan1||10/5/12 12:04 PM|
Had thesam issue. Had to do factory reset and all is back to normal.
This 4.1.6 sounds a bit suspicious. What happened to 4.1.2 through 4.1.5 ?
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/5/12 2:28 PM|
I just spoke with a rep named Jon. He wouldn't even confirm there was any problem. He kept saying this was the first he heard about it until I specifically mentioned that it affects the 16 gig models of the Nexus 7. It was as if I had to mention that "16 gig model" part like a code word before there was any acknowledgement of this problem.Then he was, "oh yeah, I have heard of that, but I haven't heard of any update." He put me on hold to research it out a little, and when he came back he told me that they are "working on it" and that an update is in the works to address multiple issues including this one. Almost identical to what the other guy, Dennis, told me - except Dennis gave dates and versions of an update.
So Jon went from no problems to multiple problems in one call, and he denied any knowledge of a specific forthcoming update. So, I have no choice but to do a factory reset at this point as I need my Nexus 7 in class next week. At this point, I have nothing but regret in dealing with this tablet. I have paid for two of them and only have one which fails to work. The other one was refused on delivery yet Google has failed to return my purchase price. They got the return three months ago.
I mentioned to Jon that I thought this should not be a regular update waiting for some normal update schedule as many people basically have useless brick on their hands. This needs an immediate fix, and barring that due to Google not knowing how to fix it, then they need to send out one of those pesky communications they hate to send letting people know what is going on. This can only get worse, I think. Where is Steve Jobs when you need him to deny a problem? Why isn't this a news story like "AntennaGate?"
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||10/5/12 3:16 PM|
I was wondering the same thing. This should be in the news. You see tons of glowing reviews of this tablet, but there is no mention of this. Its a serious problem that prevents you from using the storage space you paid an extra $50 for. I can barely use this tablet anymore, even typing takes forever. I love Google, but I would not have purchased this tablet if I knew that this tablet would come to a screeching halt after only a few weeks of using it. If there was some media coverage maybe Google would move their @$$ on this. We'll see if we get the update this weekend. If not, maybe we should start emailing some media outlets about the "amazing Google tablet."
|Nexus 7 slow when less than 3GB free||Masupilami||10/5/12 11:39 PM|
Count me in, mine is slow as hell. I'm praying for a fix soon...
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/6/12 2:50 AM|
That's sad.... We have a Nexus device, a Pure Google Device, The Google Tablet with a huge problem, many (most?) are affected and no one in Google said something officially.
Except a Google Emplyee who just said "Thanks for the reports everyone, we're investigating."
more than 1 month ago... I've never expected this.
249 billion dollars cap company 50000 employees.
Google? Are you there? Can you say something? Will you fix this problem? When? We've paid this tablet and it becomes pretty unusable...
Paul are you there? What about this looooong investigation?
Dont want to be rude but.....
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/6/12 2:52 AM|
FInally did the factory reset and while the tablet performs better it is still slow and misses keystrokes. The Androbench is still horrible although improved in some areas. In others it hasn't changed much at all. Tragic! I tried to return in at Sam's Club today as I thought there was a 90 return. But they are only 30 days so am stuck going through Asus for this. God help me! I'm about to throw in the towel.
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||10/6/12 6:39 AM|
Paul, are you still taking trade ins? I can click on Chrome's icon, go get my cell phone, unlock it, open chrome, do a Google search and load a website before my Nexus 7 can get chrome open. Its insane. This tablet is completely useless. Please update us as to what is going on and what Google is doing to fix it.
Fly, just buy a brand new Nexus 7 at Sam's, take the new tablet out, throw your old tablet in the box and return it to Sam's for a refund. At least you'll have a tablet that will run quickly for a little while. Hopefully an update really is coming...
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/6/12 7:00 AM|
I've actually returned my launch unit to the store (this is my third Nexus, the first one had a screen which deeply disliked being attached to the rest of the tablet) and got a new C90K model. Hopefully it'll not suffer the same fate as the old one, but I'm still very, very reluctant to fill this over the death limit and find out...
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/6/12 7:02 AM|
Oh yeah, FYI C90Ks ship with 4.1.1 on them.
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/6/12 7:26 AM|
This isn't like antennagate because it doesn't affect all the devices and isn't easily replicatable on all units (and a quick straw poll of people I know with them suggests it's not actually very common).
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/6/12 7:55 AM|
Im sure it affects most of the devices out there, and remember that there are so many people who dont fill the space so much and sometimes the problem is not so heavy (so people could say yes its slow but its ok) and there are tons of people who doesnt know this group or google groups in general.
Not easy to replicate? This the most easy problem to be replicated I have ever seen. Just fill the space storage with everything.
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||10/6/12 8:25 AM|
Colin, if you decide to test out your new Nexus 7 and it doesn't slow down when you fill it up, would you please let us all know. So far it doesn't seem like the C80K devices have been any better, but I haven't seen any posts from anyone with a C90K serial number. If the problem has been fixed at least there is hope that we can trade our bricks in for real, working Nexis 7s.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/6/12 9:28 AM|
Anyone here have a C60? Just curious.
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||10/6/12 12:04 PM|
C70 here. Well, its past noon in Cali and still no update. Not looking good.
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||10/6/12 1:53 PM|
Just called customer service. Like the representatives that many others have talked to, this one said he had never heard of this problem. I'm sorry to say, I really don't think a fix for this is in the works. I told him about all the different forums discussing this issue, this google group, and the article by The Register (http://www.theregister.co.uk/2012/09/11/nexus_7/) and I told him about my benchmark results. My random write speed is now 14.97 operations per second -- normal for Nexus 7 is listed on AndroBench as 8306.81 operations per second, so I've got 0.18% of the random write speed I should have... a SLIGHT slow down). He made no promises of an upcoming fix.
They're going to send me a replacement 16GB model and if it has similar problems, he said I could downgrade to the 8GB Nexus 7. If I can't use every last GB of storage, then why did I pay an extra $50 for the extra room? Might as well get my $50 back and go for the smaller-capacity device, right? 8GB seems so small though... :(
|Re: Nexus 7 slow when less than 3GB free||Chris Roemmich||10/6/12 3:38 PM|
Mine is slow as heck too. AndroBench write scores are horrid like everyone else here.
|Re: Nexus 7 slow when less than 3GB free||mjflynt||10/6/12 3:53 PM|
Google and Asus are definitely aware of the problem. Asus guy wanted me to do a refresh as the OS "became corrupted in memory" - yeah, ok. He acted like it was happening a lot and knew the remedy right away. And two of the three Google guys knew about it, but one I had to coax a little to get him to admit it. The one that didn't know about it probably needed coaxing too, but I gave none to him. I have the C60 model. I refreshed and it does prefrom better on the interface, but the benchmarks are still quite awful. I think the problem night recure sooner than it took to first manifest so am not excited to reload this thing at all.
How does buying another one at Sam's Club and returning this on in the box work? Don't they check serial numbers on the device?
|Re: Nexus 7 slow when less than 3GB free||Masupilami||10/6/12 5:34 PM|
Is there any update on this problem? Or shall i just replace my Nexus
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/7/12 9:19 AM|
Worth pointing out that, out of the box, benchmark scores for the c90K were still at the wonky side of ass awful, but daily usage is mmuch better.
|Re: Nexus 7 slow when less than 3GB free||jbird92113||10/7/12 12:01 PM|
I have been reading an interesting article about a new android version 4.2 that is going to be released in the next few weeks. I wonder if the fixes will beincluded.
|Re: Nexus 7 slow when less than 3GB free||McChen||10/7/12 1:52 PM|
apparently the newer nexus 7's are shipping with an updated 4.1.1 build, JRO03S. i wonder if this has a fix for the storage lag issue. it's not available as an OTA yet, though someone has made the image available for the adventurous. http://www.theandroidsoul.com/update-nexus-7-to-jro03s-latest-android-4-1-1-jelly-bean-build/. hopefully this will be pushed as an OTA soon
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/8/12 4:21 AM|
I've got one of the units with the new build, but there's no way in hell I'm going to fill it up and find out if it resolves the issue.
|Re: Nexus 7 slow when less than 3GB free||Cliff Coleman||10/8/12 5:28 AM|
Good thinking. Never fill up that extra space that you paid for.
|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/8/12 7:13 AM|
Can't say I'm ecstatic about it, no.
|Re: Nexus 7 slow when less than 3GB free||David Combes||10/8/12 7:23 AM|
So can Google provide us with an update on progress. I finally ended up wiping my device, and surprise surprise the lag has gone away. Can Google indicate when they are going to fix this?
|Re: Nexus 7 slow when less than 3GB free||RoboCuz||10/8/12 8:10 AM|
Hey Paul, is there any chance you or someone else at Google can update the specific #37258 issue that is created? It seemed that was a correct official place to go to report the issue, but it hasn't seen any response from Google. Is that the right place for everyone to go to star, and highlight the number of people having this problem? One thing I am hoping to help, is make sure Google is aware of the extent of the problem, since I see various places where it is showing up, either in the news, or in various forums, and I am not sure if people understand the BEST place to inform Google of the issue, not the existence of it, but highlighting the extent of it, so they (you) can realize the scope of how many customers are being affected. The second concern or thing I am trying to fix, where should people be watching to see if/when something is being done? Here? The issue page mentioned above? I am just trying to understand the best way to engage your company, since there are a number of different locations that seem to be mentioning it that feel sort of official, and not sure which is the right one; trying to cross link properly, I guess :)
|Re: Nexus 7 slow when less than 3GB free||MiscFiles||10/8/12 8:49 AM|
I've reported this problem to Google. The woman I spoke to (Stephanie) said that she had not heard of this issue, or any proposed software fix. She recommended trying a Factory Reset, and if that didn't work ordering a refund/replacement from my retailer (eBuyer in the UK). She said that she would pass the issue on.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/8/12 8:52 AM|
Its October 8th 2011. Do you know where your 4.1.6 update is?
Oh yeah, I have a new issue where my "n" key lost sensitivity and its annoying. I have to go back and type it in. Grrrr!
|Re: Nexus 7 slow when less than 3GB free||garpunkal||10/8/12 8:58 AM|
getting a little bit fed up of no feedback... all we want is an answer to whether this is a software/hardware fix and whether google/asus are going to do something about it really :(
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/8/12 9:28 AM|
I think we should write to the bosses Vic Andy and Hugo about this problem on G+...

|Re: Nexus 7 slow when less than 3GB free||Micah Stewart||10/8/12 11:53 AM|
Maybe Google will let us trade in our bunk 16gb devices for the 32gb devices coming out later this month.
|Re: Nexus 7 slow when less than 3GB free||RoboCuz||10/8/12 12:24 PM|
That would be one way to make an unhappy customer (me) turn into a happy customer (me); a bump from a broken 16 GB to a working 32 GB would let me forget the hours of pain resetting and restoring my pad repeatedly....much as I hate to say it, it would work on me. I guess everyone has a price, that would be mine :)
|Re: Nexus 7 slow when less than 3GB free||Paul||10/8/12 1:12 PM|
Google is still working on this. To be clear, the JRO03S build doesn't include any changes that affect this issue.
|Re: Nexus 7 slow when less than 3GB free||Chris Roemmich||10/8/12 1:16 PM|
|Re: Nexus 7 slow when less than 3GB free||Paul||10/8/12 1:19 PM|
The code site is one place we check for bug reports, as is this forum. I'd like to reiterate that we are aware of this problem and are investigating. We are also aware that this is affecting 16GB owners.
We don't typically update the bug report page, but I will certainly update this thread when there's new information to share.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/8/12 1:29 PM|
Oh thank you Paul this is what we were waiting for, you guys are aware of the problem and working on it! Take your time guys and thank you for this update!
|Re: Nexus 7 slow when less than 3GB free||Chris Roemmich||10/8/12 1:45 PM|
I just wiped mine.. it's slower now, lol.. time to image and hope it fixes it.
I called support about an hour ago. The tech said he was aware of the problem and has reported it to the dev team, but didn't have much to say other than that. Paul just responded above saying he will update this forum as news becomes available.
|Re: Nexus 7 slow when less than 3GB free||Cliff Coleman||10/8/12 1:51 PM|
Thank you for the update Paul. I am guess that there's little chance of getting a time frame for a fix?
|Re: Nexus 7 slow when less than 3GB free||IwanZ||10/8/12 1:56 PM|
I also wiped my device and it was faster. So I was curios if the performance will stay if I fill up the device. So I filled it up that I only had 1 MB left, then deleted 130MB and started androbench. After that I deleted another 5 GB, restarted the device and ran the benchmark again. The results are:
Who every asks himself if the issues reoccurs: YES it does!
btw. can anyone post the benchmark, how the device should perform? I think my device is still not as fast as it should be even just after the factory reset.
|Re: Nexus 7 slow when less than 3GB free||Bill Vinson||10/8/12 3:36 PM|
Thank you, Paul! It makes a huge difference to know that Google is aware of it & looking into this... I've been lurking here & accidentally allowed myself to run low on space (I shouldn't have to care but knew of this issue) & now I'm just hoping for a fix...
|Re: Nexus 7 slow when less than 3GB free||Paul||10/8/12 4:24 PM|
I've posted on this thread many times FreedomITA, including a post stickied on the very first page with the most important update. :-)
Be sure to skim these longer sorts of threads and look for posts by people with the Google Employee badge or the Top Contributor badge for posts from Google or forum volunteers.
|Re: Nexus 7 slow when less than 3GB free||phlegmish||10/8/12 5:39 PM|
I guess you can't tell us if it is hardware or software related.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/9/12 3:06 AM|
OT Sorry everyone
Sorry Paul, I knew it but I wrote that post because we (consumers)are usually accustomed to bad services by many companies,
especially about warranties... many time we've heard "sure we'll take care of you because of this problem", "we'll fix it",
"we'll release an updated for your phone by...for free" "we'll repair your device for free" and then... silence or "we are sorry but..."
I know its not your fault...
Never had a problem with google after buying a n1 ns gnex n7... this is the first time and Im sure you guys REALLY think different and
work better than others.
|Re: Nexus 7 slow when less than 3GB free||Sebastian Geisler||10/9/12 3:11 AM|

|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||10/9/12 4:58 AM|
Cheers Paul, thanks for checking in. I think people need to be sensible about this, don't expect a fix to arrive in a matter of days. Software development just doesn't work that fast unless you're cutting corners.
|Re: Nexus 7 slow when less than 3GB free||Filippo Corti||10/9/12 7:18 AM|
I think that a both side sensible approach is a good compromise. :)

Google Announces The Android 4.1.2 Update - Being Released To AOSP Today
|Re: Nexus 7 slow when less than 3GB free||burnduck||10/9/12 10:14 AM|
Android Police just reported android 4.1.2 being released and mentioned something about the PMU on the N7.
I'd assume it's not really related to the issue we are facing but maybe some community rom enthusiast might want to try it out?

|Re: Nexus 7 slow when less than 3GB free||Chris Roemmich||10/9/12 12:33 PM|
No worries... doesn't seem to have fixed it.
|Re: Nexus 7 slow when less than 3GB free||rob0t||10/9/12 1:35 PM|
A full test will probably require a factory reset with the new version...
|Re: Nexus 7 slow when less than 3GB free||RoboCuz||10/9/12 1:52 PM|
I agree, a full reset is probably needed for the test, but my initial impressions are NOT GOOD. I got the update, and I now have lag AGAIN, as if I went over the limit, even though I still have just under 5 GB free (4.96). So the update seemed to trigger the issue, even though I had enough space available. Sigh. Now I need to do a factory reset just to get back to my old performance from before the update. I hope others have better luck....

It does appear that /something/ has changed that has improved write speeds (on my device, at least). Device seems snappier to me - some apps were taking *minutes* to load before!
I will wait for a few days for final opinion though. Would be nice to get confirmation that this release is targeting this issue though.

I've been following this thread for weeks. I have a C70 model (stock) and it's quite horrible for performance. It has gotten to the point that I rarely use the tablet. I think there are many others out there with this problem but are just watching and waiting. I know of 8 others with the problem.
I'm optimistic that 4.1.2 might increase the write speeds and help mitigate the terrible performance. I'll post my read and write times pre and post update as others have done once I receive my update.
I worry that if the issue is not mitigated or long lasting, that all of us will be without support for even longer. While a friendly posting on the forum is helpful, I think everyone wants an official response.

Did you reset your device before updating? or did you simply update? It would be good to know in case what you are seeing in the benchmarks results may not necassarily reflect the Android update but the factory reset.
|Re: Nexus 7 slow when less than 3GB free||McChen||10/10/12 2:42 AM|
I've been testing 4.1.2 on my nexus 7 which has no mods whatsoever, pure stock, unrooted. so far the signs are encouraging. from the changelog, it appears that there were device specific changes to the nexus 7, enabling TRIM to work. Previously on 4.1.1 I had filled my device to about 1GB free space left and it began to lag horribly. I cleared some space to about 5GB free, no change. Deleted more to 9GB free, a little bit better maybe, but still pretty laggy. Verified with Androbench that write speeds were the culprit. Was getting about .5 MB/s sequential write and 18 IOPS on random writes. Updated to 4.1.2 and right after the update, ran Androbench. Speeds were horrible in everything both read and write, I think the OS must have been doing stuff in the background. Let it sit for about 15-20 mins to finish doing whatever it was doing and re-ran Androbench. Scores were now back to where they were with 4.1.1, good read, but horrible write still. What I found that it takes time for the performance to restore. I am guessing that TRIM is happening in the background, but I don't know under exactly what conditions the OS begins to do this or how fast it happens. I tested after about an hour, then an hour after that. It got faster each time. I left it with the screen off and charging, figuring that is most likely when the OS would think it is idle and being to TRIM in the background. I am now at 10.3MB/s seq wr and about 60 IOPS for rnd wr and the tablet is much faster and not laggy any more. I still have about 9GB free on the device. I'll let it sit a bit longer to make sure the TRIM fully completes and then bench again. The TRIMing doesn't appear to happen that quickly, it takes a few hours at least it seems. I also then need to fill the device up again and re-test. But things are looking good so far!
|Re: Nexus 7 slow when less than 3GB free||McChen||10/10/12 3:01 AM|
another thing that i was thinking of.....i'm not sure how trim really works on linux/android. Like if the OS will just periodically go and clear unused blocks of previously deleted files? or does it only trigger when a file is deleted, so it would be better to copy some large files to the tablet then delete them. perhaps my results were just a result of a small amount of cleared blocks as the OS creates and deletes things through normal usage (sync, etc.) some more testing is in order...
|Re: Nexus 7 slow when less than 3GB free||MeGuinness||10/10/12 4:50 AM|
the update as definitely speeded up the n7,after running androbench it is clear some work as been done to solve the problem,......it seems to works!!!
|Re: Nexus 7 slow when less than 3GB free||McChen||10/10/12 4:51 AM|
i copied over like 7GB of files to my device and then deleted them to make sure TRIM was triggered. that really opened up the performance even more. random writes are 120+ IOPS, and the SQLite and Macro scores improved massively as well (I only have a vague idea what those represent, documentation doesn't really give details). when the device was nearly full, I did bench it and it was really slow and laggy (expected). also copying files over MTP was very slow and the transfer seemed to crap out a lot, requiring restarts (also expected) but now if i fill the device again, it should transfer much faster and stay fast after I did the initial clearing. I haven't done that yet, the testing continues, but i'm so happy to see my tablet back to the performance I remember when i first got it, it hasn't been that way for awhile now!

This has affected my 16GB Nexus 7, now. I am very disappointed in the lack of response to this problem that is rendering your tablets USELESS! If I could return it for a refund, I would, but I am stuck with a $250 papeweight.

|Re: Nexus 7 slow when less than 3GB free||waxsta||10/10/12 9:06 AM|
Try the Anroid 4.1.2 update. I would imagine that you should get a prompt to install it. I am hearing that it fixes this issue.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 10:32 AM|
I still didnt have the prompt for it, so I did some research and learned how to get it on there manually.
I have a Nexus 16GB, I've always kept it above around...5GB to avoid this issue since I heard about it right after purchasing. Going to push my luck now and see if 4.1.2 really does fix said problem. If not, looks like I'm gonna hafta restore.
I hope this is the end of this, because I'm going to be really perturbed otherwise. This is my first Android device so I'm not exactly feeling wowed.

|Re: Nexus 7 slow when less than 3GB free||burnduck||10/10/12 12:41 PM|
Write speed seems to be still pretty horrible when storage is full, but it's now recoverable by deleting and freeing up space.
It is nonetheless a workaround but not ideal.
One thing I have noticed is that the tablet seem to be freeing up space from somewhere when the storage space is full. At one point I thought I have filled up the whole tablet, went back to settings and there was one more GB to go.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 1:12 PM|
Those are the same results I'm getting. Fill it up to capacity and its unusable. Fill it up to ~4GB remaining and it works fine.
I feel like it's probably a hardware issue, and work arounds are all we're going to get. It's been going on for months now and it's a pretty big deal so it'd probably have been fixed by now if it could. Just a lot of posturing going on.

|Re: Nexus 7 slow when less than 3GB free||Paul||10/10/12 1:39 PM|
As you may have heard, Android 4.1.2 has started rolling out. This update includes a fix for 16GB Nexus 7s which may experience slower performance when running out of storage space. Android 4.1.2 is being distributed via over-the-air (OTA) update over the next several days; if your tablet hasn't received it yet please be patient.
If you're experiencing this issue and installing the update doesn't immediately resolve the it for you, I have a couple of recommendations. You can fill the device's memory up and then remove a few megabytes worth of data. Alternatively, you can reset the device (Settings > Backup & reset > Factory data reset) the tablet. After you've done either of these you should be able to re-fill the tablet's memory as much as you like without encountering this issue again.
I'd like to thank everyone on this thread who reported this problem, and especially those who helped us troubleshoot the issue. Your assistance is greatly appreciated.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 1:42 PM|
Not working for me. On 4.1.2 with a C80 build, if I fill up, no matter what I do it remains chuggy as all get out until I remove several gigs of files.
I also tried a factory reset, same deal. 0.80 write when below 2 or 3 gigs.
|Alex Hensley||10/10/12 1:44 PM||<This message has been deleted.>|
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 2:04 PM|
Actually... its behaving oddly.
Let me share my experience:
I fill it up, as it starts to hit capacity, it slows to to a complete crawl and becomes unresponsive. I can go in, and test it, and the speeds are way down.
Then I delete some files, random, small files, few MP3s, some stuff like that, and it's speed suddenly returns, ok nice.
Then I put something else back on it? Speed back down until I start some erases again.
I am highly confused.
|Re: Nexus 7 slow when less than 3GB free||disparkys||10/10/12 2:26 PM|
First of all hi everyone!So question, does that mean that I have to reset my nexus in order to get it to go fast again? Also, did everyone get their update? Cause nothing yet for me :(
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 2:38 PM|
No, you can just erase some files. The fix seems fairly hodgepodge in that if you start to fill it up, it can stutter and slowdown with poor write speeds, but if you remove those files all is well again.
Seems more like a temporary work around, but by Googles recent grand declaration of it being fixed, I'm not too confident I'll ever get the data I space I paid for.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/10/12 3:07 PM|
Hey Alex, instead of deleting just a few files delete several GB worth (like, at least 3). After that it shouldn't slow down even if you fill it close to capacity.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 3:27 PM|
Well, I've already wiped it as part of my attempts, but I'll try again with just typical file movement.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 5:09 PM|
No good, kept trying to remove large files and replace them with slightly smaller, as well as reboot the device, etc.
Just flips between bouts of being OK and bouts of chugging, stuttering, delayed opens, etc. Ran a few bench marks, often dipped into around ~0.5 seq write.
I dunno what else to say, it seems very random, based off of adding and removing things from the memory. I've been playing with it all day, I did a full reboot, I've tried everything and it's driving me crazy.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 5:14 PM|
A full restore, I mean.
My read always seems ok, but it's the write. At it's normal its around 9-11, when it wants to throw a hissy fit it sinks to 0.5 or below
|Re: Nexus 7 slow when less than 3GB free||Jim DeArras||10/10/12 5:37 PM|
Thanks, that fixed it!
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 7:27 PM|
Did another reset, filled it back up, same deal. Horrible write speeds slowing down the whole OS.
27.7 seq read
0.49 seq write
7.12 ran read
0.03 ran write, haha

|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/10/12 8:02 PM|
Personally, I never had any issues pre-4.1.2 because I kept above the 3GB threshold this thread warned about
Post-4.1.2, I went ahead and filled up, and it looks like that's simply a no-no regardless. Seems like a hardware issue that cannot be fixed. Well, you get what you pay for, I guess. =/
|Re: Nexus 7 slow when less than 3GB free||McChen||10/10/12 8:29 PM|
after upgrading to 4.1.2, i filled my device completely, with less than 1MB free space. i deleted about half a gig and benched. pretty laggy and slow, where i was with 4.1.1. deleted another half gig, so at 1GB free space. performance much better, passable. deleted another gig, giving me 2GB free space. performance back at full. so performance does seem to still tail down as you fill up the device, somewhere below 2GB is where it starts to affect the device, down to 1GB was still livable. but somewhere below 1GB it gets pretty frustrating. things are definitely improved though and performance can be restored by deleting files, unlike 4.1.1 where once you hit the lag, deleting files didn't restore performance.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/11/12 5:09 AM|
Trying my tests again this morning, same results as you, McChen.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/11/12 6:35 AM|
Oddly, it seems to be working now.
I think, based on what I'm reading, part of my issue is that rather than clearing a block of data, I decided to go right for the format to fix it up and when I did the barrage of fresh device sync stuff in conjunction with running benchmarks and a full disks was throwing the OS off.
I'm new to Android, but that's the guess I'm weathering. I'm at 120ish megs remaining and running at full speed, so I can't complain. Just hope it stays this way, will go about my normal routine and post an update if I have any problems or in a few days.
|Re: Nexus 7 slow when less than 3GB free||jbird92113||10/11/12 8:21 AM|
Did you do a full factory data reset?
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/11/12 1:02 PM|
I did, but I don't think it actually had much consequence on anything.

Curious if people in the US still haven't received the update?
|Re: Nexus 7 slow when less than 3GB free||burnduck||10/12/12 4:27 AM|
I believe android OS frees up spaces from cache files, the more data you put into the storage, the more frequent the freeing operation is, so I assume that would degrade performance to certain extent.

|Re: Nexus 7 slow when less than 3GB free||JGT||10/12/12 2:33 PM|
I sent my N7 in from the original group of volunteers. I now have my replacement, which seems to be working fine (speed-wise). I have updated it to 4.1.2 also.
The only difference I have noticed, however, is that the case I bought - which has an embedded magnet to wake/sleep the device - no longer works very well. I managed to get it to work with a more powerful magnet, but even then it's not consistent. Did something else in the hardware/software change related to this?
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/12/12 8:35 PM|
I'm in the US and didn't get the update so I went manual install. So far so good. Tablet seems ok for the moment other then the fact I have to re-type the "n" key because of some strange sensitivity issues on that key.
|Re: Nexus 7 slow when less than 3GB free||bargun||10/14/12 12:40 PM|
I am losing faith in google products. My nexus7 is unusable now, s3 phone doesn’t work well with GV, vizio co-star is full of bugs.
I was making fun of overpriced apple products but now i am spending hours on the internet to solve the issues with google.
|Re: Nexus 7 slow when less than 3GB free||Paul||10/15/12 10:09 AM|
I'm not aware of any changes to the magnet system JGT.
|Re: Nexus 7 slow when less than 3GB free||may1||10/16/12 10:26 PM|
Unfortunately, the OTA update DID NOT solve the problem for me. What is worrying is that even if I reset the device (both from the OS and the hard reset), storage performace remains very low; here are AndroBench micro -benchmark results post hard-reset:
SEQ RD: 12.43mb/s
SEQ WR: 5.76mb/s
RND RD: 973.42 IOPS (4K)
RND WR: 84.27 IOPS (4K)
Needless to say, my device remains laggy even after resetting, and downloading from google play is taking more time (5gb worth of download is taking more than 12hrs and counting, on a 10mbps connection).
|Re: Nexus 7 slow when less than 3GB free||Paul||10/17/12 1:41 PM|
Most of the feedback I've seen in this forum and other communities is that the update did address the problem, may1. If you received the update and your tablet still has performance issues, it's possible that you're experiencing similar-sounding symptoms from an unrelated issue and I recommend contacting Google Play about a warranty replacement.
|Re: Nexus 7 slow when less than 3GB free||may1||10/18/12 8:07 AM|
Thanks for the reply. Do you know what the unrelated issue is, and is the standard nexus7 a global warranty? I purchased the unit in the UK, but I live in Japan...
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/18/12 10:43 AM|
Just a heads up if you missed Paul's updated, after the update it was just a tiny bit faster, but after I deleted about 4 gigs to get about 9 gigs free it started flying again even when I filled it back up with data, so if you got the update but did not delete a few gigs that is what I had to do to get it fast again
|Re: Nexus 7 slow when less than 3GB free||Paul||10/18/12 11:33 AM|
I do not know what the issue is. The warranty applies in the country you purchased it from; you'll have to claim your warranty through the UK.
|Re: Nexus 7 slow when less than 3GB free||Alex Hensley||10/18/12 2:43 PM|
I've seen about a 50/50 split, with a lot of people claiming they've fixed it not doing total fills.
This is where I am, and a good friend as well. This is my first Android product in general and I'm sadly very annoyed by this issue.
Will probably just have to jump back on the ol iPad bus next cycle, I've spent about 5 hours working on this issue and my good graces are spent.
|Re: Nexus 7 slow when less than 3GB free||Jim DeArras||10/19/12 6:34 AM|
This was a total fix for mine. Went from a paperweight to the tablet I originally bought.
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/19/12 6:42 AM|
After you upgraded to the new software did you then go and delete at least 3 gigs of data? After I applied the update it was not faster, but then based on Paul's advice I deleted about 3-4 gigs and it started flying again like new, I then filled it up to about only 1 gig free and it's still flying at full speed, but again, to get there after the update I HAD to delete at least 3-4 gigs (Tried only 1 gig at first but that was not enough)
|Re: Nexus 7 slow when less than 3GB free||IwanZ||10/19/12 7:36 AM|
I also had the problem and the update did not solve it. I reset the device, then filled it up and deleted 10GB (so it was almost empty again), but the Random Write was at 0.02MB/s, which is not acceptable.
So I called Google Support to get the RMA and replace my product. Let's see if the second one does not have the issue.
|Re: Nexus 7 slow when less than 3GB free||Jim DeArras||10/19/12 9:05 AM|
It does take a while to recover. The SSD has to erase all the deleted files, and that is a slow process for a large deletion. Give it a day or two, and you'll be surprised.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/20/12 11:54 AM|
What to know whats pissing me off? 32GB Nexus 7. Thats what. I just bought my 16GB Nexus 7 only a couple months ago. Now there is a 32GB Nexus 7 for the same price! WTF? This pretty much pisses off all of us who adopted the 16GB version. I dont care about a 25$ credit that came with the unit. It's nothing compared to DOUBLE the space. Whats worst yet, 16GB versions will be PHASED OUT! WTF?! This makes me cringe at buying another google branded product if they are going to pull tactics like this! Cheating customers is NOT good business practice! I'm so pissed right now!
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/20/12 12:10 PM|
If you wait more months I bet another improved version comes out.
If you wait a year I bet a new generation of Nexus 7 comes out.
Welcome to buying tech products.
|Re: Nexus 7 slow when less than 3GB free||IwanZ||10/20/12 12:24 PM|
I agree to SoverignKnight. The first product is only 2 months old and there is a new Generation available? That's just tooo fast and realy not a great strategy for people who bought it. I feel like a stupid beta tester without agreement. The new version is with enhanced features on Basis of the issues we faced.
|Re: Nexus 7 slow when less than 3GB free||disparkys||10/20/12 12:27 PM|
@rsplatpc 2 months isn't exactly the same as a year. Especially when they haven't started even worldwide distribution.
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/20/12 12:28 PM|
What enhanced features are included except more storage?
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/20/12 12:33 PM|
If you wait there will always be a better product, Google is doing this to fight the iPad mini that is coming out, they need to place their tablet with more storage than the iPad mini for the same price, they would not have released a version of the tablet with more storage for the same price if Apple was not coming out with the iPad mini, this is Google fighting for market place, not screwing over consumers, try calling Google when the 32gb is released for the same price on the 29th and asking if you can trade up and see what they say.
|Re: Nexus 7 slow when less than 3GB free||disparkys||10/20/12 12:39 PM|
They'll say yeah right, and laugh out loud. Who in their right mind trade in a used "inferior" product with a new one? They might (best case scenario) give £10 market credit. Which is actually worse than nothing.

I think what is the key points here is #1) 16GB phased out. Replaced in only a couple of months?! What the hell?! The Warranty hasnt past even 6 months yet! They might as well just forget it ever exsisted. #2) SAME PRICE. I'd understand if it was $300.00, but same price? That's an insult. I sure hope Google/Asus is going to put a trade up program in place. I understand having to raise the stakes because of that POS ipad mini.. but pissing off customers WITHOUT thinking this through and as to what impact it would have on customers who just bought the 16GB version.. well thats definately not consumer friendly.
|Re: Nexus 7 slow when less than 3GB free||Paul.Cahill||10/20/12 6:20 PM|
How about as a gesture of goodwill, Google enable mounting USB sticks in OTG mode so users don't have to root and install stickmount.
|Re: Nexus 7 slow when less than 3GB free||rsplatpc||10/20/12 6:45 PM|
I like my 16gb Nexus 7 very much, that is why I bought it, all tech products come with buyers remorse, I use a 99 cent OTG cable and a $20 64gb flash drive and put all the media I need when I'm traveling on it and it works perfectly with Nexus Media Importer, so when I need it to be it's a 80GB tablet to me when I want it to be :-)
|Re: Nexus 7 slow when less than 3GB free||IwanZ||10/20/12 11:44 PM|
Mounting USB devices without root would be great! This is the only reason to root my device. But it is another topic. I do not want to put other devices on that mini and quite unstable slot! I think it will break after some months. So having the storage in the device would be the best option to keep the nexus alive for more than one year.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/21/12 9:09 AM|
I agree. That just seems like a cumbersome, risky solution. #1 rooting voids warranty. #2 Far to easy to break the USB port this way and also wears the USB port out faster changing between charging and USB stick. I'd rather Google/Asus do a trade up program for the 32gb version. That would definitely make allot of 16gb N7 customers excited and happy.
|Re: Nexus 7 slow when less than 3GB free||kevmartin||10/21/12 1:35 PM|
A trade up program sounds wonderful but is totally unrealistic. There is a perfectly good option available for trading up. It's called eBay.
|Re: Nexus 7 slow when less than 3GB free||SovereignKnight||10/22/12 3:01 AM|
All this means is I should avoid buying Google branded devices if they pull stunts like this. To phase out and abandon a product already within 3 months means that you can't have any confidence in that device. I understand 6 months, but 3 months?! I'm getting a Samsung next time. I'll get an SD slot AND I know all get a device that isn't replaced with another at the same price in a mear 3 months! Not even Nvidia has a refresh of a video card at the same price in 3 months!
|Re: Nexus 7 slow when less than 3GB free||IwanZ||10/31/12 1:03 PM|
I got the replacement device and unfortunately this one is not really faster. I attached some results from anrdobench:
1. Pic 4._Screenshot_after-reset-emptied-storage.png
This benchmark was taken with my old device with 4.1.2 after filling up the storage and deleting around 7GB
2. Pic 1. Neuer Nexus nach einschalten.png
Taken when the device arrived without putting any data into with with android 4.1
3. Pic 4. Neuer Nexus 10gb frei Versuch 2.png
Taken after filling up the device and removing 10GB with Android 4.1.2
I ran all the results multiple times, but there was not really an improvement! I think I have to call Google Support again. It is getting on my nervs. I thought I bought a nice fast device, but this one is just slow. HD videos are not always played smoothly and gaming is also not really fun.

|Re: Nexus 7 slow when less than 3GB free||IwanZ||11/1/12 10:00 AM|
well I tried it as well, but my performance did not come back. Deleting apps, rebooting and having around 10GB free space did not help.
What is for you acceptable performance? 127IOPS is not really great for random write, that is around 0.5MB/s. Of course compared to my 0.4MB/s (106IOPS) which is a difference of 25% compared my to yours.
If you checkout the ranking, then the performance of both our tables is very very very very bad!
@Paul: What numbers shall the tablet have? I hate it to guess.
|Re: Nexus 7 slow when less than 3GB free||mmaestro||11/1/12 10:21 AM|
127IOPS, 0.5MB/s for Random writes is pretty normal on the Nexus 7. Ignore what you see in the rankings: those numbers are almost meaningless because so many people are tweaking their N7s, using ramdisks, and fiddling with caching and the like.
If your sequential writes are in the range of 10MB/s and your random writes are over 110IOPS, you're probably doing OK.
It seems like the problems were caused by flawed garbage collection. The patch fixed that, but it didn't tell the system where garbage collection which previously should have been performed but hadn't been should occur. You can fix that issue by filling your storage and then deleting the contents, or using an application to get the same effect. I used Forever Gone to get the effect (it may cause a hang/crash when you really start getting low on storage - if it does, just restart and continue). I have seen some reports of the lag returning after a few weeks. Running Forever Gone again seems to fix the problem yet again, but given the way flash storage doesn't like repeated writes, if you find yourself having to do this repeatedly I'd RMA. FWIW, I ran Forever Gone once, it fixed my lag issue, and it hasn't returned since.
|Re: Nexus 7 slow when less than 3GB free||JGT||11/16/12 9:05 AM|
Now that 4.2 is rolling out, a few people have noticed slowdowns on the N7 (including me, with a replaced device).
Anyone else notice this? Should it be moved to a new thread?
|Re: Nexus 7 slow when less than 3GB free||smac3||11/21/12 2:24 AM|
This issue has started to creep back again on (4.2).
I have tried all of the suggestions barring the following:
"Alternatively, you can reset the device (Settings > Backup & reset > Factory data reset) the tablet. After you've done either of these you should be able to re-fill the tablet's memory as much as you like without encountering this issue again."
I am a bit reluctant to do this because it may be a waste of time if it fails to resolve the problem. Has the reset this worked for others?

|Re: Nexus 7 slow when less than 3GB free||Colin Whiteside||11/27/12 6:15 AM|
I'm another one who's running into this again after the 4.2 update. Could someone please check Asus actually included the fix in the 4.2 firmware update?
|Re: Nexus 7 slow when less than 3GB free||McChen||11/27/12 6:37 AM|
I had the storage slowdown problem with 4.1 that the 4.1.2 update fixed. Then my tablet got slow again with 4.2. I tried clearing the cache as some have suggested, but that didn't make any difference. I eventually found that turning on rotation lock fixed it. Please let me know if this also works for anyone else.
I also notice that if you have multiple users, the tablet can get slow if both users have processes running. I think it's because the system is just running more things, so CPU, IO and RAM have to be shared. But if you have multiple users, the user processes only startup when you login for the first time. So if you only login to one user, it won't affect the tablet. But once you login to the other users, I can't find any way to log them out, other than rebooting.

This is a reply to Paul from Google's post before:
Most of the feedback I've seen in this forum and other communities is that the update did address the problem, may1. If you received the update and your tablet still has performance issues, it's possible that you're experiencing similar-sounding symptoms from an unrelated issue and I recommend contacting Google Play about a warranty replacement."
MOST of the feedback on this forum says exactly the opposite. I personally feel that Google is not doing enough, if anything to admit this issue and sort it out REGARDLESS of where your warranty resides. This is a widely publicized and known issue to many users. I am not willing to send my device back to the US, at my expense, just to have the device returned with the same issue everyone is still experiencing.
Googling: Nexus 7 slow 3gb returns 129000 results!!! Telling people to disable Currents and other background tasks is just masking the issue.
If Google publicly states, either through yourself on this forum or any other means that they are FULLY AWARE of this issue and will issue a complete swap out for the latest version that has no screen falling off, slow charging and random reboot issues AND they will pay for shipping then I will accept that they done the consumer a decent service.
Anything short of that is not acceptable

Ruald, you may have missed my post from October 10th (a few days before the post you quoted) where I indicated that the main bug people in this thread are discussing is addressed in the Android 4.1.2 update. Please review that post for details, including suggestions if the issue isn't immediately resolved upon updating.
|Re: Nexus 7 slow when less than 3GB free||galapogos01||1/8/13 8:06 PM|
Can you advise us of the specific fix included in 4.1.2 that was supposed to address this? It appears many are still having the issue post the update.
It also appears the issue affects multiple devices which use the Tegra platform. http://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=37258
|Re: Nexus 7 slow when less than 3GB free||DocWhizzer||1/9/13 5:15 AM|
I just sent my Nexus 7 back to Google because of how slow it is. It did get slightly better after the update, but it's still nowhere near as fast as when I first got the device. It's somewhere between its speed when new and it's slowest speed, but is still very laggy, sometimes taking several second to open gmail or chrome. It's almost like they had it overclocked for the initial reviews when it came out and then the update slowed it back down so it would stop overheating and causing the glass to fall off. The replacement is just as slow. I've given up hope that it will ever be back to its original speed.
|Re: Nexus 7 slow when less than 3GB free||Prajith kv||2/13/13 9:53 PM|
real solution is to keep at least 3GB of storage free at all times. http://mobotalks.com/android/nexus-7-very-slow-performance-when-less-than-2-or-3gb-free-solution/

|Re: Nexus 7 slow when less than 3GB free||Molly Buck||2/18/13 1:00 PM|
I have the 16GB nexus 7 with update 4.2.2 and we still have this issue. About every 3 months we have to run a factory data reset, because once you go over the less than 3GB mark it doesn't matter if you delete the files or not, it's to later. The slow probem will not go away unless a factory reset is done. This is getting old!!! When is this going to be fixed? Or are we going to need to RMA the device in order to get this fixed?
|Re: Nexus 7 slow when less than 3GB free||MiscFiles||2/19/13 1:04 AM|

|Re: Nexus 7 slow when less than 3GB free||hurikhan77||3/11/13 12:31 PM|
Did anyone try the fstrim app from the app store to solve this problem? I've read about this in some forums and it sounds like it would really fix this specific problem. But it needs root and I don't want to jump through all the efforts of rooting my device until knowing that it will work.
So did anyone try it?
I'm also suffering from this problem. As soon as the device goes below 1 GB free storage it works slow as hell. And even if I free up storage it will never get back to the speed it had before. That is very disappointing. Clearing cache from the storage settings menu helps a little bit. Also formatting the cache partition helps a little bit. But it never got back to the speed I had before first hitting this "magic" storage barrier. I suppose even a factory reset won't really help as that "only" formats the storage but does not really reinitialize the flash memory.
Some forums say this is a known bug in some Nexus 7 kernel versions. So I think even if it is fixed now in an update, remnants of non-trimmed free flash space still occupy performance in my flash memory and the only way would be an fstrim to fix it. Why does Google not natively run that on a regular basis in the device?
|Re: Nexus 7 slow when less than 3GB free||hurikhan77||3/11/13 12:37 PM|
From what I learned about this problem from forums (flash trimming bug in some kernel versions of Nexus 7) this could really fix the problem by filling up all free space (so overwriting trimmed and untrimmed regions), then free this space again (which would - with a hopefully bug-fixed kernel - trim all this flash memory and make it available to the flash controller again as free space). Thanks for the link, I'm going to try it.
In the worst case (non-fixed kernel) it would slow down the device even more because the flash memory controller would have no trimmed free space available as the result.
|Re: Nexus 7 slow when less than 3GB free||a1exus||3/28/13 9:51 AM|

|Re: Nexus 7 slow when less than 3GB free||Freeman D||5/8/13 8:31 PM|
Posting my experience here with a 16 and 32gb model.
16 started to lag a bit, noticed screen bulge, and seeking. Did the qtip trick with no improvement, it got so slow i started messing around and found out I only got the 16gb not the 32 I wanted. Restored and back to the store. The 16gb model had a screw missing inside that did nothing to help with the bulging or squeaking.
Back home with the new one, I noticed it slowing down more and more with use, with 23gb left I ran forever gone and the whole tablet instantly started to run faster.
The new one did not start out with any screen bulge, but it appears it might slowly be happening.
|Re: Nexus 7 slow when less than 3GB free||Michael Guittar||5/13/13 7:22 PM|
I ran forever gone. No improvement. It takes about an hour to boot up, about 2 days to be usable after an app install. Unusable during app installs, which take about 1 hour.

I love you Paul and the company you work for. Please prove to me that I can continue to be proud of you guys. It pisses me off that I spent around 225$ for the 16 gig unit and I'm having a problem like this when the nexus 7 was so popular for its outstanding speeds in comparison to the other 200$ tabs out there as competition. If I was in control of Google and was assigned to this task, it would have been resolved a long time ago. So pull up your bootstraps and get on that horse and ride! Like starting now...... Thanks guy.

Hey Xandcraft? Stop threatening people because you are not gonna bully your way out of this. I'd like you to see and try filling a lawsuit (which I'm surprised you are able to spell), for a device that costs so little and yet you expect everything to be working better than expected. Grow up, and if you have the money for suing people, try investing them into buying a better tablet.
|Re: Nexus 7 slow when less than 3GB free||samw5||6/21/13 8:24 AM|
I think that's besides the point.
He's a pretty frustrated user trying to express his disappointment with the product. There is nothing wrong with that, no matter how strong the words can be or threats.
I think IMO it doesn't matter how cheap the product is, it's just supposed to be working well otherwise the vendor should be standing behind it. Price really should have little to do with it, it's just good customer practice.
I also think that enough people have expressed concerned about this particular issue for Google to maybe recognize the problem or at least try to look into it (I'm one of those unhappy users).
|Re: Nexus 7 slow when less than 3GB free||Ruald Andreae||6/21/13 8:44 AM|
Although I agree with your opinion that Xandcraft is being a bit childish I do have to say that your view on "investing to buy a better tablet" is just wrong. No matter what the cost of the device was, it's a "Quality" product from a reputable hardware vendor and a massive online service company who makes billions from us viewing adds on their tech, that claims to do xyz but only does z and we paid money for that product.
Telling us to just deal with it is ridiculous!
I also don't think Xandcraft is referring to himself suing Google personally as that will never work. He is referring to a class action lawsuit on a grand scale where we would all collectively stand as one and sue Google for providing a faulty device and not happily going out of their way to make it right. Like the many class actions against Apple for similar issues. This is not a threat, just an observation. I couldn't be bothered with something like that and honestly it shouldn't even get that far. If Google has any modicum of an idea of what the term "Customer Service" really means then none of us would be here complaining and we all would have had new tablet shipped to us happily. From my most recent experience with GoogleApps I have absolutely ZERO faith in Google's ability to provide anything close to customer service or a good customer experience. My DNS records were accidentally deleted by Google and ALL my services were down for FOURTEEN DAYS and having the worst customer experience I have ever encountered (and thats really bad coming from someone who lives in a 3rd world country). Being sent from one clueless tool to another clueless tool who does not understand the concept of providing regular updates and following up on their promises. Being told to contact a 3rd party myself, then being told by the 3rd party, no I must call google, again being told by google, call the 3rd party and, oh yeah you bet it, being ONCE AGAIN told to call Google and only after being completely and utterly down for 10 days did Google suddenly click, woops our bad and still took 4 days later to fix the problem.
So: TL;DR Google customer support is terrible and they don't care that it's terrible. Maybe they can have a moment of genuis and fix our problem now? Doubt it...
I'd like to add that I have also tried forever gone app and it has only slightly improved the lag. It has now gone from completely unusable to slightly annoying. The device is nowhere near the "buttery smoothness" that it was on day one and you know what I am NOT going to flash it once again. Flashing your device should not be the only solution, it's annoying, you have to run backups, and then the backup doesn't backup everything and then restore stuff badly, it's horrible.
I like the Nexus AOSP interface, I don't like any skinned interfaces and I don't like Apple products. I want a working device which does what it promised to do for the price I paid for it, no matter how "cheap" you think it is, $200 is not that cheap in my country so it's not the argument. The argument is, there are NUMEROUS people online complaining about the same thing. Numerous websites telling you how to tweak your Nexus to improve speed, just to make it usable, turning off currents, running forever gone, turning off this and that. NO, thats not what i bought. Here is just one such site:
The VERY first line says it all:
"Everyone seems to be complaining about their Nexus 7 tablets slowing down over time. Sure, this is anecdotal — but there are a lot of anecdotes."
From this forum alone and the amount of complaints I have seen this is FAR from anecdotal. 11,400,000 search results for Nexus 7 slow and 25,300 for the more specific "Nexus 7 slow" term. Don;t even get me started on the nexus slow charging problem (takes over 14 hours to fully charge my device from the original charger and cable and any other charger)
Google, something is WRONG, your loyal Nexus devotees are revolting and all you got is some dude named Paul giving advise here and there. Sorry not good enough. Recall, replace, get it sorted.
|Re: Nexus 7 slow when less than 3GB free||disparkys||6/21/13 9:14 AM|
Trust me, I know how frustrating Google support can be! If you scroll back, you'll notice that I was one of the first people to complain about this issue, but since Google is not responding, I'm not going to keep complaing and threatening about it.
You are right, it is not fair to the customers, but tell me a big company that has good customer support. The power is in our hands, we either return our devices back to the manufacturer (ASUS) since we have a 2 year quarantee on the product that is clearly malfunctioning, or when the next nexus device comes, we don't buy it! Until then, we can only advice the people that are interested in buying one, NOT TO!
(Irrelevant to the thread) Within the first month, my screen cracked and it took me a month and a half of back and forth between google and asus to get it replaced.
So if you feel like we should do something about this bug, I'm more than willing to help, but I'm tired of people threatening!
|Re: Nexus 7 slow when less than 3GB free||Ruald Andreae||6/21/13 10:06 AM|
This company for one:
and this is the best one:
"regarding customer service: Google Play customer service is horrible. There are several nice reps, but almost none of them actually follow through to resolve an issue with a return for refund (even from the "managers" that told me they would contact me with a follow up email and didn't, on more than one occasion). It took OVER A MONTH to receive my refund from Google after receiving two defective units and returning both, and that was after MANY phone calls and emails to them before I could get one person who finally truly took responsibility and followed through. If you order this directly from Google and have any issues, you may wait a very long time to get a refund, so you might want to go to a retail outlet to purchase instead, where you can actually get an immediate refund if needed. Google's customer service is nothing in comparison with Amazon's wonderful customer service, and that's a fact."
Almost exactly my experience with GoogleApps. No-one followed through on promises and no-one bother to take ownership of my issue and as a result my domain was down for 2 weeks. Got no refund, no good will from Google.
The proper way for Google to have handles this entire fiasco would be:
1. ADMIT THE PROBLEM
2. Release a fix (Allegedly this happened but the fix didn't fix anything until you apparently run some 3rd party tool to fix "the fix" that "the fix" fixed. WTFIX????)
3. Notify the users of the affected devices that a fix was released and include a simple app with the fix which does what forever gone does.
4. Gladly offer to collect and replace the device if the fix does not solve the problem without argument and delay.
nuff said. sort out your customer service or yeah, I vote with my feet.
|Re: Nexus 7 slow when less than 3GB free||Paul||6/21/13 10:51 AM|
The specific issue this thread addressed back in the fall of 2012 was fixed in the Android 4.1.2 update. If you're experiencing issues with a slow Nexus 7 as its memory fills up, please refer to my post where I walk through some steps to run through if your device is already on 4.1.2 and still experiencing this problem.
If you've tried those steps and are still experiencing a slow device when its memory is filling up it's very likely not related to the issue this thread originally covered, so I encourage you to discuss your concerns on a new thread.
To help cut down on confusion by any newcomers to this thread, I'm going to close this one to further replies.
