Nexus 4 kitkat - bluetooth problem - worst sathish $kumar 11/23/13 5:27 AM
I have Bluetooth speakers. I have 2 problems.

1. When connected, volume set to maximum always. If you reduce volume, goto volume settings & do nothing.. Again volume set to maximum.


YouTube goes to TV mode. Not able to see videos in nexus7 or nexus 4 clearly.

Re: Nexus 4 kitkat - bluetooth problem - worst bitt3n 11/23/13 2:07 PM
I have this same problem. It's horrible. Attempting to lower volume via the bluetooth device or the onscreen slider does nothing. The slider goes down but the sound doesn't, and then the slider goes back to maximum. Makes headphones unusable.
Re: Nexus 4 kitkat - bluetooth problem - worst Seanwil12 11/24/13 8:44 PM
I have the same issues! Need a fix...
Re: Nexus 4 kitkat - bluetooth problem - worst DString 11/25/13 5:20 AM
Same issue, needs to be fixed ASAP.
Re: Nexus 4 kitkat - bluetooth problem - worst triniprodigy 11/25/13 7:18 AM
Same issue here as well.
Re: Nexus 4 kitkat - bluetooth problem - worst Michael J Graves 11/25/13 10:57 AM
I have the same trouble, in my case using Nexus4 and Plantronics Voyager Legend headset.

Incidentally, the problem does not occur on Nexus7 (2012) running KitKat.
Re: Nexus 4 kitkat - bluetooth problem - worst Andrei Lupsa 11/26/13 1:14 AM
I have Nexus7 (2012) Kitkat and LG Tone+ HBS-730 and I have problem with volume.
It is not always maxed, I can change it, but..
Min volume is too loud.
And changing volume is unpredictable, sometimes it jumps to max.
Before KitKat update it was ok.
Re: Nexus 4 kitkat - bluetooth problem - worst Jonathan Y 2000 11/26/13 9:49 AM
exactly the same issue with LG Tone+ HBS 730, used to work fine with 4.3, but after kitkat upgrade volume is set to max always and render the headset unusable.

google, please fix the issue ASAP.
Re: Nexus 4 kitkat - bluetooth problem - worst Serge van Neck 11/26/13 9:58 PM
Having the exact same symptoms after 4.4 update. LG HBS 730.
Re: Nexus 4 kitkat - bluetooth problem - worst Natxo Hernández García 11/27/13 1:39 AM
Same with Nexus 4 and SBH50. I have disable notifications because they can be harmful.
Re: Nexus 4 kitkat - bluetooth problem - worst Fred_2 11/27/13 5:04 AM
Same volume issue for me !!!!
With Android 4.4, I cannot adjust the volume of my bluetooth speaker from my Nexus 4.
The sound is at the maximum level. Crazy !
It was working fine with Android 4.3...
Please correct this bug. I cannot use my speaker anymore :(
Thanks
Re: Nexus 4 kitkat - bluetooth problem - worst burningburnt 11/27/13 9:48 AM
I'm having the same problem on Nexus 4. The problem arose after upgrading to KitKat. if I try to adjust the volume via the buttons the volume resets to max.  oddly if I slide the volume in the screen it stays. Audio sounds terrible at all volumes though.
Re: Nexus 4 kitkat - bluetooth problem - worst Frank Langeveld 11/27/13 2:15 PM
Problem after upgrade to kitkat with Nexus4 and plantronics headset ledgend: they disconnect during call after about 2 minutes.

It looks like we have 2 slightly different problems in this thread:
1. Volume issue with bluetooth speakers
2. connection issue with bluetooth headset 
Re: Nexus 4 kitkat - bluetooth problem - worst Courtney Armstrong 11/27/13 2:54 PM
Having issues also with connection to Bluetooth in my car. When I'm on a call it randomly disconnects and reconnects, quite frequently.

YouTube videos I cannot watch because it wants to pair to my TV or something and screne goes dark.

Re: Nexus 4 kitkat - bluetooth problem - worst Lisa MacDougall 11/27/13 3:44 PM
Yes, my Nexus 7 (first edition) now has the same problem. Volume jumps to highest volume with blue tooth iHome speaker. No control over the volume using the side button ever since updating to 4.4.
Re: Nexus 4 kitkat - bluetooth problem - worst quinncy hinton 11/27/13 4:12 PM
Boom. WTF Bomb all over my nexus. I was going to buy a new speaker because mine is old. Its just my nexus. Lol
Re: Nexus 4 kitkat - bluetooth problem - worst Jay35 11/27/13 6:16 PM
Along the same lines, there's an issue on Android 4.3 where the speakerphone volume has a bug where it is often on full blast max volume even when the volume slider is at its lowest possible point. This generally makes the speakerphone unusable as the voices are all distorted and it sounds like the speaker may break. Going into Settings and adjusting volume there does not fix it either.
Re: Nexus 4 kitkat - bluetooth problem - worst Fabiano Engler Neto 11/27/13 10:05 PM
Same here. It renders bluetooth sound basic unusable in many cases.. If you depend on bluetooth headset to work all day, DON'T update to kitkat! Please fix asap, this is major for too many ppl!
Re: Nexus 4 kitkat - bluetooth problem - worst Maximilian Waldner 11/28/13 11:55 AM
Same for me. Bluetooth disconnects constantly on Nexus 4.
Re: Nexus 4 kitkat - bluetooth problem - worst bigboibob 11/28/13 12:33 PM
same here, nexus 4 with 4.4 connecting to JBL charge bluetooth speaker, volume is too loud, buttons or slider do nothing

Re: Nexus 4 kitkat - bluetooth problem - worst Peter Petkov 11/29/13 8:29 AM
I'm having the disconnect issue, but it happens every one minute. I think i've changed phone display sleep settings from 2 to 1 minute. Maybe this is the thing which breaks the connection.

Also if I keep phone in my hand and touch the screen every 20-30 second, BT does not disconnect at all.
I believe the old dialer had separate settings about when to sleep and turn display off while on a call.
Re: Nexus 4 kitkat - bluetooth problem - worst Tom Stefanac 11/29/13 9:09 AM
I'm having the exact same problem with my Plantronics Pro Voyager HD headset as well as my cars built in bluetooth. Prior to upgrading my Nexus 4 to KitKat I could leave the Bluetooth on any device connected for hours if not days without issue and I could carry on conversations for hours at a time until the Bluetooth battery died.

At present the phone is completely unusable in the car, I have to keep pressing the headset connect/end call button and make it search for the phone in order to reconnect during the call.

There have also been strange instances where buzzing and clicking noises in the Bluetooth are heard in the middle of a phone call as I assume it loses the encryption key.

In fact Kitkat is so bad as far as the upgrade on the Nexus 4 that I'm thinking of rolling back to 4.3 just so I can get the Bluetooth working again.

Re: Nexus 4 kitkat - bluetooth problem - worst nexus4ph 11/29/13 9:51 AM
Same problem here. Plus, volume adjustment isnt working quite well. Every time im adjusting the volume, my phone suddenly mutes.
Re: Nexus 4 kitkat - bluetooth problem - worst Chris-M 11/29/13 10:42 AM
Same.... Cannot use for work now.
1. Randomly disconnects headset
2. Volume maxed
3. Had issue with screen going black and not recovering (when bluetooth disconnected as above)

This type of issue should not get through testing.
If this isn't fixed quickly how can anyone trust Google phones. These updates are just too flaky.

Re: Nexus 4 kitkat - bluetooth problem - worst Homer Dong 11/30/13 7:03 AM
Ditto for the connection issue, once it's gone, the only way to get Bluetooth back on would be restart the phone. Quick fix please.

Re: Nexus 4 kitkat - bluetooth problem - worst Jeff Pristelski 11/30/13 9:02 AM
Same problem here. But I noticed that it only affects some apps.  Volume control in Google Music works, but pandora does not.
Re: Nexus 5 BT problem... dad2593 11/30/13 1:03 PM
Same issue...volume toggle has no effect on Bluetooth music device with kit Kat. Resorted to older phone to play music to Bluetooth device. Fix, please!!!

I've started a google/android dev team bug ticket with the Bluetooth issue (see link above), hopefully this will become high priority.

The more feedback and reaponses on the ticket, the more pressing it will become.

I forgot the volume issue, so please add that in if you respond.

The same volume issue on Sound Blaster SBX20 bluetooth speaker.
Re: Nexus 4 kitkat - bluetooth problem - worst Emir Kaymakoglu 12/1/13 1:09 PM
Same here. Bluetooth volume control doesn't work for my Nexus 4 (KitKat 4.4)
This is the biggest deal breaker so far!
Re: Nexus 4 kitkat - bluetooth problem - worst Moshe Kline 12/2/13 5:21 AM
Same here with Nexus 4, Kit Kat to JBL Charge- but it does work with earphones!
Re: Nexus 4 kitkat - bluetooth problem - worst Paul 12/2/13 11:20 AM
Thanks for letting us know about your experiences with Bluetooth volume and staying connected. We're investigating these issues.
Re: Nexus 4 kitkat - bluetooth problem - worst Tom Stefanac 12/2/13 5:39 PM
Paul, can you accept this ticket?

https://code.google.com/p/android/issues/detail?id=63056

Re: Nexus 4 kitkat - bluetooth problem - worst Paul 12/3/13 1:09 PM
Tom, the Android Issue Tracker you linked to is for Android's open-source code only, not its expression on any particular device. The Android Open Source folks don't generally comment on device-specific issues (their time is pretty focused on the open source side of Android). This forum is a good place to share your feedback about Nexus devices; I assure you I have checked in with my colleagues and the Bluetooth volume & connection issue discussed in this thread is being looked into.
Re: Nexus 4 kitkat - bluetooth problem - worst Tom Stefanac 12/3/13 1:37 PM
Thanks Paul,

I figured the issue tracker was a good start since I'm pretty sure the bluetooth issue is a problem directly with the BTS / BTA and something that's directly involved with the OS source code when the low power feature kicks in. Thanks for responding.

Having Bluetooth connection issues after kitkat installation with my Nexus 4
Re: Nexus 4 kitkat - bluetooth problem - worst E. Uzun 12/4/13 12:15 AM
After the kitkat update, the bluetooth on my nexus 4 is unusable at best. It keeps dropping every 20-30seconds during phone calls in my car and drives me crazy... Also the volume controls don't work for bluetooth. The connection drops are a real deal breaker as you cannot have any phone calls in the car or with a Bluetooth headset anymore...

It is hard to believe that Google  pushed an OTA update to so many devices without even testing the basic bluetooth functionality once...
Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 12/4/13 12:57 AM
Nexus 4, which I sideloaded to factory image KRT16S (not OTA) and now experiencing random disconnects with a Sony Ericsson MW600 headset I use to listen to music.  It reconnects instantly but it's really annoying. 4.3 didn't have this problem.  It can disconnect after 30 seconds or 20 minutes.  Volume controls seem to be ok for me.
Re: Nexus 4 kitkat - bluetooth problem - worst Paul Branchaud 12/4/13 6:27 AM
Over the last few weeks, I've been experiencing a similar problem: I use a profile manager app to switch my N4 to "driving mode", which turns on the Bluetooth and GPS. My car (2012 Mazda 5 if it makes any difference) pairs with the phone and I can play audio no problem, but if I have the radio on and I make or receive a call, it will drop out (back to radio) briefly (~3-5 seconds) and return. If the call continues for any amount or time, there is generally another drop out and return to function.
 
Prior to the KitKat update, I can think of only one or two times that I had lost BT connection in my car; since KitKat, I can pretty much count on every call dropping out at least once. I'm going to try an app that specializes in keeping the BT connection alive, but this is hardly an optimal solution. I am considering the N5, but if it has BT issues, I'll be waiting to see if it gets fixed.
Re: Nexus 4 kitkat - bluetooth problem - worst cesar morales 12/4/13 8:17 AM
Same problem with LG Tone HBS730 and HBS700... Hurts me ears! But my EXOGEAR Bluetooth speaker works just fine... Have no issues with volume control.
Re: Nexus 4 kitkat - bluetooth problem - worst Anton Sakharov 12/4/13 10:42 PM
Google Support proposed to do factory reset and then reinstall 4.4
I really do not want to do this without knowing if it will fix it.
Re: Nexus 4 kitkat - bluetooth problem - worst Serge van Neck 12/4/13 10:58 PM
I think I just found a fix. I had unpaired my LG HBS730 from my Nexus 7 because the volume problem made it useless, but then I thought, what if it just needs to re-pair under KitKat? So I tried this tonight, and the volume is OK now.

So my suggestion is, if you had a bluetooth device paired before the KitKat upgrade and it started misbehaving, unpair it, reboot your device, and re-pair.
Re: Nexus 4 kitkat - bluetooth problem - worst Anton Sakharov 12/4/13 11:01 PM
Not sure about the volume issue (wife's phone didn't have that issue)
but I did reconnect after 4.4 upgrade and Bluetooth still disconnects after 60-90 seconds and reconnects in 10 seconds, but only my wife's on 2012 pilot. Mine on 2012 CRV works.

Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 12/6/13 6:08 AM
Updated my Nexus 4 to 4.4.1 and so far so good my bluetooth issues have gone away.  I just hope it stays that way!
Re: Nexus 4 kitkat - bluetooth problem - worst rynobyte 12/6/13 10:16 AM
Love the HBS 730!  Works much better with Nexus 4 than my iphone 5 until now. I maintain two phones daily - 1 work, 2 personal. 
Re: Nexus 4 kitkat - bluetooth problem - worst Steve Morse 12/6/13 1:24 PM
Exact same for me with the LG Tone+ on both my Nexus 4 and 7 (2012).  Google, I really hope you're listening.

I bought Nexus devices because I love stock Android and wanted to get away from the modding community.  This has me considering installing Cyanogenmod.
Re: Nexus 4 kitkat - bluetooth problem - worst chrismartintx 12/6/13 2:57 PM
4.4.1 fixed it
Re: Nexus 4 kitkat - bluetooth problem - worst Steve Morse 12/6/13 3:23 PM
I believe you're speaking in the wrong tense.  There is no 4.4.1 currently available for the devices I mention.  Furthermore, I don't believe it has begun to roll out for the Nexus 5 yet either.  So it hasn't "fixed" anything.  Hopefully you're right and it WILL fix these issues as soon as it's released... whenever that happens.

Re: Nexus 4 kitkat - bluetooth problem - worst Marta Lopes 12/7/13 11:40 AM
HEY! I'm a total noob when it comes to adb and other stuff... But my Nexus 4 is FULL OF BUGS, always disconnecting, cant take a picture without the phone going off, cant go to internet, cant turn the bluetooth on, cant send messages, no service, sometimes i cant even turn the phone on.... HOW CAN I INSTALL 4.4.1? Please explain me. I desperately need it.
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 12/7/13 1:11 PM
nope I'm on 4.4.1 on my nexus 4. I get 5-10,mins and the connectivity is gone. only way to fix the problem is a reboot. in the car or any other Bluetooth connections
Nexus 4 kitkat - bluetooth problem - worst oscar maldonado 12/9/13 9:15 AM
I recently update my nexus 4 with 4.4 to 4.4.1 via sideload thinking that Google might have fix the Bluetooth audio problem but is still there. When I was on 4.4 I did a factory reset to fix the issue but after using the phone for a while the problem still persist and that's the same story on 4.4.1 I used to love my phone. What's wrong with Google, nexus 4 owners wait longer than other devices for the update even the moto x got it first. And even that 4.4.1 is available this issue that is the worst I've been experience haven't been fix.

Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 12/9/13 10:55 AM
Unfortunately, it looks like the 4.4.1 update didn't solve the disconnection issue, at least for me. I'm still experiencing the problem and will be rolling back to 4.3 for now. Hopefully a fix will be forthcoming.

Here's an extract of logcat during a disconnect in the hopes that it may be of some help for any Google employees looking over this topic. I'd be happy to do testing of fixes, if there are any possibilities.

steve.... downloaded it from a google server and sideloaded via adb... looked legit to me.  i have a nexus 4, a device you mentioned.  it did fix my volume problem.  there are no connection problems for me.  i have a jawbone era, lg tone+ headphones, car has pioneer deh-6400bt and belkin bluetooth receiver for my home stereo.  all devices connect and hold a connection until i kill it... typically several hours.  phone calls, music apps, podcast apps, etc all work fine.  so no, i am not speaking in the wrong tense.
Re: Nexus 4 kitkat - bluetooth problem - worst burningburnt 12/9/13 6:38 PM

My phone received an update today to 4.4.2 which I didn't even know existed.  It resolved my problem with bluetooth connections and volume control.

4.4 worked fine with Bluetooth for me. 4.4.2 is when I started having connection problems. Buy a Nexus and become a beta tester. Fix it Google!
Re: Nexus 4 kitkat - bluetooth problem - worst burningburnt 12/10/13 5:54 PM
Looks like I spoke too soon.  Listening to pandora today bluetooth cut out and reconnected itself several times.  The volume problem appears to have been eliminated though.

Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 12/11/13 1:33 AM
Nexus 4 with 4.4 had issues of intermittent disconnect/reconnect when listening to music. The short time I had 4.4.1 the issues didn't reoccur. With 4.4.2 they may have come back :-( I have now re-paired (rebooting phone after removing the pair) and not had time to retest it. Please bring back 4.3-style BT!!
Re: Nexus 4 kitkat - bluetooth problem - worst Natxo Hernández García 12/11/13 7:05 AM
4.4.2 update doesn´t fix my bluetooth problems.
Re: Nexus 4 kitkat - bluetooth problem - worst Hoshinya 12/11/13 11:32 AM
I have no problem with my volume control or it automatically disconnecting. The only problems I have with my nexus 4_4.4 is when I turn my Bluetooth off I can't hear an any sound when someone text,call, alerm going off, I have to reset my phone to restore the sound.My next and pervious button on my Bluetooth doesn't work either. Sometimes I would accidently hit the call button while listening to music and it brings up the voice command. When I close it the music seem to sound low even when the volume on the Bluetooth is at maximum. I would close the app  and bring up it again and got play I will hear the same song playing at 2 different volume.. And different time. I hit pause and the low volume song keeps playing. I'm not sure if this is all the BT problem but I will keep testing to see if there are any more bugs to find.
Re: Nexus 4 kitkat - bluetooth problem - worst Ofir Zwebner 12/11/13 11:38 AM

Re: Nexus 4 kitkat - bluetooth problem - worst John Gortney 12/11/13 1:10 PM
In addition to the OP's BT issue, I'm having several others on my Nexus 4 since the 4.4 update. In summary:

-Bluetooth failure. Auto toggles off during audio streaming
    Cannot toggle back when connected to Pioneer DEH-X6500BT
-Maps:  Very unhappy with update. What happened to labs?? I loved the +/- buttons for zoom in/out. Pinch to zoom is awful compared to the +/-. The map scale, once toggled on, is only visible when zooming in/out, but should always be visible. Can't believe they dropped turn by turn from the map  view ( with arrows to move to previous/next turn). No, I do not want to enter Navigation mode to enable turn by turn. The new UI is just awful.
-Receiving photos via MMS: not receiving any photos via MMS, principally from iPhones
-Chrome Browser: trouble loading many pages
-Battery: huge drains during minimal use. On regular work day I could get to 5pm at 60% battery, but since 4.4 I'm logging 30% at 3:30pm (despite same usage).

Hi everyone,

I wanted to update you to let you know that we're still investigating the Bluetooth connection problems mentioned in this thread. You're probably aware that the Android 4.4.2 update that is currently rolling out to Nexus devices; it does not contain any changes to Bluetooth behavior.
Re: Nexus 4 kitkat - bluetooth problem - worst Viking Xu 12/11/13 5:20 PM
no change after ota 4.4.2, bluetooth crashes and never comes up until restarting N4.
Re: Nexus 4 kitkat - bluetooth problem - worst John Snowz 12/11/13 6:26 PM
It most certainly does, bluetooth stops working and isn't able to be turned on again. You can restart the nexus 4 to have it back only for a few minutes. I'm rolling back on this bug-ridden update.
Re: Nexus 4 kitkat - bluetooth problem - worst Anton Sakharov 12/11/13 6:29 PM
@Google - why did you make .1 and .2 updates without addressing bluetooth issue.
You should be catering first to Nexus 4 users and only then to Nexus 5, otherwise we will never go to 5 but will go to competitors.
Re: Nexus 4 kitkat - bluetooth problem - worst Deniz Yorukoglu 12/11/13 6:29 PM
I'm also having Bluetooth issues with the newest update (I noticed it with 4.4.2, but might have been present with 4.4.1. 

After connecting via Bluetooth for a few minutes, it crashes and can't be turned on until a restart, I believe the problem appears when the user walks away from a wireless connection spot and enters a new one. I stopped having the problem after disabling wireless (which is of course not a good long term solution).
Re: Nexus 4 kitkat - bluetooth problem - worst Sam Schorr 12/11/13 6:31 PM
This seems odd.  I had never had a bluetooth issue before, but as soon as I got the ota 4.4.2, bluetooth turns itself off after a few minutes and will not turn back on until I reboot the phone.  Then, it will still only stay on for a few minutes again.

Re: Nexus 4 kitkat - bluetooth problem - worst Deniz Yorukoglu 12/11/13 6:52 PM
Yes, I meant wifi. I use my nexus to listen to music on the go. It appears that the problem disappears when I turn off my wifi.

I also rechecked when wifi on, and changed floors, but it didn't crash this time, yet. But I updated all my apps in the mean time. Maybe one of the apps is causing the issue if not updated?
Re: Nexus 4 kitkat - bluetooth problem - worst Vince Anido 12/11/13 6:53 PM
Thanks for letting us know Paul. I'm sure everyone on this thread would be happy to hear you guys are looking into it.

Now we just need to find a way to make everyone read your posts before they spam this thread with more complaints.

Have the same issue with disconnecting, plus Deniz Yorukoglu's issue with Bluetooth crashing and no chance to enable it without reboot on Nexus 4, Android 4.4.2
Re: Nexus 4 kitkat - bluetooth problem - worst cesar morales 12/12/13 7:03 AM
4.2.2 fixed my problem... I never had connection issues strictly volume issues. No new issues so far.
Re: Nexus 4 kitkat - bluetooth problem - worst Joel Sidwell 12/12/13 7:16 AM
I disabled wifi while using Bluetooth and this seems to have stopped the disconnect issue that required the phone to be restarted... For now

Re: Nexus 4 kitkat - bluetooth problem - worst tomsag 12/12/13 9:48 AM
On 4.4.2 it's obvious - turn WiFi off and you can use Bluetooth. It's a bug.
Re: Nexus 4 kitkat - bluetooth problem - worst wreckanoid 12/12/13 11:53 AM
I also have this issue.  Nexus 4 with 4.4.2. KitKat Not rooted.  Not running Tasker or any 'battery saver' apps. at all.  Using GoLauncher.  Bluetooth seems to switch to 'off' when leaving a wifi network (or maybe even a 3G connection) and then I have to restart the phone if I enter a different network in order to get Bluetooth working again.   This has never happened on previous versions of Android.  Most frustrating considering I have a Pebble watch.
 Paul from Google above states that there are no Bluetooth changes in 4.4.2 so this is a bit of a mystery to me.  Perhaps some sort of incompatibility with a certain app I have installed.  On we go....

 On the bright side, WhatsApp now works again!  There must have been some ART improvements in 4.4.2.  Good work, Google.  ;-)

P.S....   Just to confuse the issue..  after B'tooth misbehaving on a daily basis (having to re-start the phone to get it going) since 4.2.2 was installed, over the last thirty-six hours it hasn't shut down once.  Weird.
Re: Nexus 4 kitkat - bluetooth problem - worst Brian Lancaster 12/12/13 12:05 PM

I have the exact same issues. Bluetooth randomly disconnects and then after 30 seconds or so reconnects. Sometimes once, sometimes multiple times during a call. 

 Nexus 4, Plantronics headset. I use my headset every day 3-7 hours. This is KILLING me. I have tried to un-pair, restart, and re-pair the bluetooth connection, did not work. Ready to try a factory reset... Pulling my hair out, MAJOR bug for me as this is absolutely critical for my work. 
Re: Nexus 4 kitkat - bluetooth problem - worst Rick_W 12/12/13 7:49 PM
I read over code.google.com that someone came up with the following steps:

wifi
advanced
wifi frequency Band set to 2,4GHz

I followed the steps and was able to have a normal conversation with my Nexus 4 was paired with my Jawbone headset. I have not tried streaming yet.

Re: Nexus 4 kitkat - bluetooth problem - worst chauvetp 12/12/13 10:00 PM
There definitely seem to be bluetooth issues with 4.4.2 that were not in 4.4.1.  If bluetooth was not changed then some related portion was changed.

As others have described, my bluetooth goes out and can only be reenabled (for a short time) with a reboot. Nexus 4 user here as well.

Re: Nexus 4 kitkat - bluetooth problem - worst tomsag 12/13/13 12:25 AM
Solved the same problem with turning WiFi off. Since then I do not have any problems with my Headset.
Try it.
Re: Nexus 4 kitkat - bluetooth problem - worst Peter Petkov 12/13/13 12:49 AM

Re: Nexus 4 kitkat - bluetooth problem - worst O. L. 12/13/13 1:43 AM
Excellent.

This is apparently true for the Bluetooth Low Energy stack as well.

I have been running a Bluetooth Low Energy application that would disconnect after something like 3 to 40 minutes on 4.4.0. Switched off wifi when I saw your message yesterday and have been running continuously since.
Re: Nexus 4 kitkat - bluetooth problem - worst frederic fernandes 12/13/13 2:42 AM
it's still amazing to read what google helper say, I had a problem with the bluetooth on my nexus 4 with the latest 4.3, and google told me so the reason for the loss of connection with my car came from the firmware of my car.

I waited for the update to 4.4, and it's strange because I have'nt the problem with the bluetooth connection with my car. Today with 4.4.2, I have again a problem with the bluetooth but now it's with my headset.
And
the google answer is that "the bluetooth will although they have not done anything at this level" and maybe the must it's turn off wifi when you want to use this bluetooth.
other than that everything was working fine.
asshole.
Re: Nexus 4 kitkat - bluetooth problem - worst MIshaMsk 12/13/13 2:47 AM
I did have problems with bluetooth when using it with my car before 4.3 but it was just bad and noisy rather than disconnecting. At those time disabling wifi helped too. I've already forgot about it but know reading this thread it seems that current connection issue have the same root. Will try to turn off wifi though this is inappropriate and inconvenient solution anyway. 
Re: Nexus 4 kitkat - bluetooth problem - worst Andrew S Taylor 12/13/13 2:56 AM

Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 12/13/13 2:58 AM
Nexus 4 with 4.4.2. I've still experienced disconnects when listening to music through a bluetooth headset with wifi set to 2.4 only.
Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 12/13/13 3:01 AM
Forgot to mention. Had my first BT lockup the other day while wifi was on and set to auto.  Had to reset the phone to get BT to switch back on.
Re: Nexus 4 kitkat - bluetooth problem - worst sleeper692 12/13/13 6:22 AM
I have 4.2.2 on N7 2013. I had no problems using A2DP Bluetooth headphones until the 4.2.2 update. After the update, the bluetooth will stream music to my headphones for anywhere from 5 to 20 minutes then the BT shuts down on the tablet and will not turn back on. I have rebooted and each time it hooks back up immediately only to shut down a while later. It is a very frustrating thing to happen while commuting on public transportation.
Re: Nexus 4 kitkat - bluetooth problem - worst Scott Hartman 12/13/13 8:37 AM
Have the same problem in my 2013 Honda Pilot.  Will disconnect and reconnect very frequently during a call.
Nexus 4 running 4.4.2
Re: Nexus 4 kitkat - bluetooth problem - worst uniqueadventures 12/13/13 8:59 AM
I have also noticed that it isn't just my Bluetooth that is broken but I can't get a GPS signal anymore either. (Nexus 4 android 4.4.2 everything seemed to be fine before... Oddly my nexus 7 which has also updated to 4.4.2 has shown no issues...)

Thanks Google.  Your update has broken my phone. I have no idea when it will work as it should again. Please at least make some sort of announcement or response to this thread to say you are trying to fix it and give an approx. timescale ?

Re: Nexus 4 kitkat - bluetooth problem - worst Alex Sh... 12/13/13 9:06 AM
The same problem. BT drops connection or switched off by itself and then impossible to turn it on without reboot.
Fixed it by flashing old radio from 4.4. Now testing. So far no issues.

Can confirm - 24 hours with old radio (from 4.4), and no problem so far.
Re: Nexus 4 kitkat - bluetooth problem - worst Paul Branchaud 12/14/13 7:13 AM
I finally received the 4.4.2 update, and taking a hint from a previous poster, I changed my "driving" profile to disable wifi, and I had my first uninterrupted conversation in over a month. After the 4.4.2 update, my "driving" profile was a little sporadic on turning Bluetooth on, but after restarting the phone, everything seems to be working fine now.
Re: Nexus 4 kitkat - bluetooth problem - worst Ido N 12/14/13 9:30 AM
Hi Paul,

As you probably know the Nexus 5 has similar Bluetooth connectivity problem.
I previously wrote  a post (Nexus group/nexus 5 bluetooth problem) about the problem to connect my nexus 5 to Toyota Yaris hybrid or to BMW x3. Other nexus 5 users wrote about the problem with other car types. No official response from Google so far.

I actually purchased 2 devices of nexus 5: one for me and one for my brother.
Interestingly, only my device has the Bluetooth problem !  unstable connection/pairing (in 2 car types) - it connects for a few seconds and than lose connection.
This problem started with 4.4 and continued with 4.4.2, we tried factory reset or safe mode - but nothing solves the problem!
(My brother device stably connect with no issues/problems before and after the 4.4.2 update).

I wonder if its an hardware problem (so how can  I replace the device?) or a software bug (so when its going to be fixed? why only some devices suffer from it?) 
 
Thank you,
Ido

Re: Nexus 4 kitkat - bluetooth problem - worst Vince Anido 12/14/13 7:42 PM
The workaround of limiting the WiFi band to 2.4ghz seems to have done the trick for me as well. A nice stop gap for those having issues.
Re: Nexus 4 kitkat - bluetooth problem - worst Yiannis Stavroulas 12/14/13 11:42 PM
I get the disconnection issue every 1-2 minutes when I talk on the car with my plantronics Backbeat go 2, and bt shuts down sometimes too. When on my office, I experience no problem but I don't know if it's not moving, being on 2g or being on wifi that solves it.

Interestingly, using my older Samsung bt, I think it's hm 6540, works fine in the car.

I got this all after upgrading ota from 4.4 to 4.4.2 on nexus 4.

Google guys, is there a workaround like using 2g or disabling wifi? Needless to say this is critical for all of us that use the mobile in the car. We're going to get fined eventually. Please provide a fix now.

Re: Nexus 4 kitkat - bluetooth problem - worst Giuseppe Violante 12/15/13 12:44 AM
I have a slight different problem, since upgrading to 4.4.2 while connecting to my car bluetooth device i can not hear and talk to people any more. The only way is to turn bluetooth off and use speaker phone...annoying as hell
Re: Nexus 4 kitkat - bluetooth problem - worst Calum Lawson 12/15/13 2:33 PM
I've only started to experience problems since 4.4.2. Bluetooth will shut down on the phone and cannot be restarted. I've tried a variety of things, enable and disable Aeroplane mode, switch to 2.4Ghz wi-fi only, switching wi-fi off but none of them have any effect. The only solution is to re-start the phone.

Obviously something has been pushed out that's unstable and causing us issues. Fix soon please Google, it's very frustrating having to power cycle my phone a couple of times a day just to be able to use it with my Ford's built-in BT for music and calls.
Re: Nexus 4 kitkat - bluetooth problem - worst Vince Anido 12/15/13 2:59 PM
Ugh - scratch that. Just had a drop.

Perhaps it's "less bad" with this work around? I can't say for sure. Perhaps it's just that I feel like I'm doing something, rather than just waiting.

No concern if I use an application android official.

Re: Nexus 4 kitkat - bluetooth problem - worst Yiannis Stavroulas 12/17/13 5:06 AM
Update: It looks like shutting down WiFi does the trick. As soon as I disable it, the bluetooth connection becomes stable. I have only done an hour of testing, but no disconnections experienced at all, so maybe some of you people want to try it. It may be an affordable workaround until we get a fix, which I hope will be soon.

Hi Paul,

Was something changed to bluetooth in 4.4.1? My Nexus 4 went straight from 4.4 to 4.4.2. Until thuis update bluetooth was working fine. Now it disables after some time and the only way to get it working again is rebooting the phone.

My Nexus 4 running 4.4.2 also randomly disconnects from my car's bluetooth (a Motorola Roadster) and sometimes reconnects. However, when it does not reconnect I need to reboot the phone and then it works again. Very annoying and kinda makes bluetooth useless for me.
Re: Nexus 4 kitkat - bluetooth problem - worst Fiefster 12/18/13 12:02 AM
Nexus 4 running 4.4.2 has unstable bluetooth as well. Random disconnection and BT will not turn on again until reboot. Has only started since upgrade to KitKat.

Bluetooth dropping for me as well, only during phone calls though. Music streaming is fine for hours, but once I make a call, after about 20-30 secs, bluetooth is dropped. Really annoying, I dont use it frequently, so I dont know whether it was 4.4.1 or 4.4.2 The first kitkat had no problem in that area for me...

Re: Nexus 4 kitkat - bluetooth problem - worst peyush agarwal 12/19/13 1:22 AM
My nexus 4 was fine with Jelly Bean. When OTA KitKat installed first, my working bluetooth pairing with plantronics M50 earpiece stopped working completely. I gave up, then eventually got 4.4.2 OTA upgrade, and it began to work again. Until today, when I discovered BT not connecting, then discovered the BT was turned off on the phone and I could not turn it on. I slide it, it fights for 2 seconds then slides back to off.

Google, can you please fix this? We just can't deal with such high level of instability with the updates.
Re: Nexus 4 kitkat - bluetooth problem - worst Woscht supp 12/19/13 10:06 PM
Have the same problems as mentioned above. Also a clean flash with the current factory image did not solve my problems.
When the Bluetooth connection is lost, i have to power oft and on again to reconnect.
Also the handsfree profile is not working with my car or headset, only a2dp music streaming.
When i activate the handsfree profile in the device settings, a2dp will not work any longer ;-(

Re: Nexus 4 kitkat - bluetooth problem - worst Olivier Coma 12/20/13 1:33 PM
Hi Paul,

Are you sure you are still investigating ? It's been more than one week that the migration from 4.4.0 to 4.4.2 causes bluetooth disconnections to pretty much every Nexus 4 user... Don't you have Nexus 4 at Google ? I am a software developer and I wonder if you figure out well what happens to a product / company, which name is different from Google, when such huge and evident problems / regressions occurr ! The product / company will just disappear ! And Google does what for its customers ? Nothing at all. No communication, no update, nothing. Just a word to say there is no change into 4.4.2. But compare to what ? 4.4.1 ? It sounds like Nexus 4 was not concerned by 4.4.1. And the bluetooth was working in 4.4.0... So if there was no change between 4.4.2 and 4.4.1, you have to compare the development branches 4.4.0 and 4.4.2, it is obvious, no ? I am very frustrated against Google. The Nexus 4 is the last Google phone I buy for sure because there is no support at all... If you are not able to support phones -> don't provide new Android releases for them. The minimum you could do is to explain how to switch back to 4.4.0 or to 4.3.0 without having to reinstall everything on the phone. Is it possible at least ?

Regards,

Re: Nexus 4 kitkat - bluetooth problem - worst Ansgarr 12/20/13 1:40 PM
I started experiencing this issue with the OTA drop of Android 4.4.0-- although, I do agree that the support for this bug has been severely lacking.

I've also tried contacting the Nexus support center, but the support person did not provide any details on a bug fix. Instead he suggested the common fixes (e.g. reboot phone, unpair and re-pair bluetooth devices, etc.)
Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 12/20/13 3:24 PM
Olivier,

I'm not Paul, nor am I a Google employee, but perhaps I can at least answer a few things for you with my knowledge. Firstly, Bluetooth issues were present in 4.4.0 (KRT16O and KRT16S), I know I experienced them. Secondly, based on the comments I've read here, it seems there are several different issues with Bluetooth and they are manifesting differently. That makes it much more complex of a problem than it might otherwise be. I'm suspecting some interactions with the radio firmware that was updated along with 4.4.0 and 4.4.2 and the OS itself, but I don't have much to back that up.

As for rolling back to 4.3, that's difficult to do without a factory reset. You can certainly try, but it'll require you to have an unlocked bootloader. If you don't have this already, the unlock will wipe your phone. If you're unlocked, grab the 4.3 factory image and look at the contents of the flash-all script (bat or sh). Run those commands manually, but on the last line, the one with the "update", don't use the -w switch. You'll need to clear the cache and dalvik cache at the very least before doing a bootup or you're looking at major problems booting. You may also have some applications that updated to 4.4-specific apks you'll need to re-install. Have fun if you decide to downgrade without a wipe.

Note that you can use Clockworkmod Helium (http://www.clockworkmod.com/carbon) to backup your applications with our without root before you do those steps. I recommend using it or Titanium Backup (needs root) to be safe. Alternatively, you can also use adb backup.


All,

The best solution to the problem that I was having (BT connection drops randomly then re-connects) is to disable the 5GHz WiFi band. It's not enough to disable WiFi temporarily unless you also disable "scanning always available". The much easier alternative is to force 2.4GHz. In the WiFi Settings, tap on the overlow icon at the bottom right. Choose "Advanced" from the popup menu. In the next screen, choose the "Wi-Fi frequency band" option and select "2.4 GHz only". Doing this, I was able to have a succesful 35 minute conversation without any drops.
Re: Nexus 4 kitkat - bluetooth problem - worst vylum 12/22/13 6:23 AM
Hi Youngmug,

I am definitively going to try your force Wi-Fi band tip, I will post here whether it works for me too.

Thank you!

Re: Nexus 4 kitkat - bluetooth problem - worst DaveMorgan 12/22/13 9:33 AM
Disabling the WIFI (including the "always scanning") does nothing to help. I have a few devices that just will not keep a connection to my phone. As far as handsfree goes, this is a safety issue. I need to be on the latest OS because I am a dev. 

It's very frustrating considering how much money I've spent on Nexus devices in the past. I wish they would just let me trade in my N4 for a N5 with a little upcharge (assuming they tested bluetooth on the N5).
Re: Nexus 4 kitkat - bluetooth problem - worst Olivier Coma 12/22/13 12:04 PM
Thank you for your answer Youngmug,

I tried your solution and it worked fine but not all day long. The bluetooth works better with your recommendations (e.g. the bluetooth worked well for a couple of hours instead of a couple of minutes on my phone), but it did not solve all the bluetooth problems on my phone. Thanks also for your explanations for rolling back. Well, it seems to be more secure to do a factory reset, so I think I will do this in a couple of days if nothing is done from Google...

Regards,

Re: Nexus 4 kitkat - bluetooth problem - worst Damon Lane 12/22/13 2:01 PM
I have similar problem with playing music causing the bluetooth on my phone (Nexus 4)  to crash. Tried a factory reset and things have improved. I seem to be able to make calls through bluetooth without problems, but as soon as I try to play music it crashes and I have to restart the phone in order to get it back.

Not impressed by the way if anyone at Google is listening - which, judging by the silence, they are not.
Re: Nexus 4 kitkat - bluetooth problem - worst Sonar98 12/23/13 2:34 AM
Yesterday I flashed the radio image from 4.4 on my 4.4.2 nexus 4.
The Bluetooth problems seems to have vanished.

Unfortunately I had to wipe everything on my phone because the bootloader was locked.

I hope Google will do something quickly. It is killing me.

This makes me think that just some of the Bluetooth profiles have issues, not all of them. Unfortunately CTP is a really important one if you want to use your phone for calling people :) 
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 12/23/13 8:12 PM
Google rep, I know its Christmas and chances are no one is there but do you happen to have an update? . Also noticed today that my N4 will not connect to my ODBII reader via Bluetooth. it connects and drops instantly. this is my fist first experience with your OS and device, hope this is not a normal thing.
Re: Nexus 4 kitkat - bluetooth problem - worst Brandon Fleming 12/24/13 10:52 AM
Same here. Disconnects constantly then reconnects and repeat cycle... 4.4.2 on Nexus 4
Re: Nexus 4 kitkat - bluetooth problem - worst CadetD1 12/26/13 9:57 AM
OK, so I am not crazy. Something definitely broke when I went from 4.4 to 4.4.3. 
Same problem here. (Among other bugs introduced by that release). 
Re: Nexus 4 kitkat - bluetooth problem - worst Yogi Sadhwani 12/26/13 11:14 AM
I success fully downgraded to 4.3 Jellybean and guys its working flawlessly with my car, headphones and sound bar. No crashing caller app no buggy music player I also turned off the 4.4 upgrade notification by holding on the notification for 3 sec.
Re: Nexus 4 kitkat - bluetooth problem - worst vylum 12/27/13 5:36 AM
I don't know why but it seems to be getting worse by day. Now regular calls don't even work. Radio signal to provider is dropped at least every hour and after dialing I get disconnected before the wait signal sets in. This is really disappointing. I got a nexus for fast updates, I did not realize that I was buying myself into a test panel!

Next phone will be htc, no more nexus for me!

Re: Nexus 4 kitkat - bluetooth problem - worst John Tedder 12/27/13 6:50 AM
When the Google guys have finished their Christmas celebrations I suggest they admit that this has got them beat and issue a reverse upgrade (downgrade?) back to 4.3 there's not much we can't live without in 4.4 and it seems plenty we could do without. has anyone asked LG what they think about all this? 
Re: Nexus 4 kitkat - bluetooth problem - worst dbkc397 12/27/13 6:53 AM
We'll keep in mind if you are going to go to another device. All android OS is Google. So going from Nexus to HTC is still having to endure poor or incomplete updates from Google. Sounds like going back to 4.3 is the way to go. At least until sometime next year when 4.4 is finally fixed. Thanks Google!!!
Re: Nexus 4 kitkat - bluetooth problem - worst wembly81 12/27/13 5:42 PM
Is anyone also having wifi issues? The bluetooth issue started when it was updated to kitkat, and the phone would intermittently turn bluetooth off and it wouldn't come back on.

Now it SAYS it's on, but it's not working at all. And wifi isn't working at all either.  It shows available networks, appears to connect, but I never get an icon at the top of the screen. Not sure what to do.
Re: Nexus 4 kitkat - bluetooth problem - worst sleeper692 12/27/13 11:26 PM
I've seen a couple of minor wifi connection problems.  I've only had it happen a couple of times over the last couple of days (of heavy use) but I have had my N7/13 disconnect from my home wifi then reset and reconnect.  I didn't have to reboot or reset anything.  It simply reconnected on its own.  I thought it might be my router.  I was using Chromecast at the time so maybe there is something buggy with that setup.  Anyway, yes, I've seen indications of wifi trouble but it hasn't been anywhere near the problem the BT is.  If my wifi dropped connection like BT I'd be at the post office sending the tablet back.
Re: Nexus 4 kitkat - bluetooth problem - worst Jack Franzen 12/28/13 2:20 AM
Good job collecting data everyone. The last thing we want to hear is niche car problems. The current and most important issue is that Bluetooth will shut down and remain that way until the phone or tablet is restarted. The 2.4 GHz and WiFi off 'fixes' don't work. the dual band WiFi and ability to use the internet are pretty important to me anyways.

Here's some data:

When this problem occurs, I open up play music before the restart and it shows that gmusic is still registering the device. Maybe gmusic is causing this but probably not. Anyways here's a clue!

Edit: here is the list of the 6 services and process that all start when I try to enable Bluetooth. When it fails these processes all shut down. 7 seems like an awful lot to be starting up all at once

Re: Nexus 4 kitkat - bluetooth problem - worst Olivier Coma 12/28/13 2:32 AM
The only solution I found to solve the bluetooth problem was to roll back to 4.4. It was the first time I tried to do that, it took me a couple of hours, but now I can use my phone normally (i.e with bluetooth in the car). I followed this tutorial and all happened well : http://www.droidviews.com/how-to-downgrade-firmware-on-google-nexus-devices All the data wiped out but at least I can use my phone now !

Re: Nexus 4 kitkat - bluetooth problem - worst Alex Sh... 12/28/13 10:06 AM

Unfortunately yes.
But honestly speaking what they can say? Paul already said that Google is working on this issue. And the fix (hopely) will be as part of next upgrade. But since politics of Google is to keep next upgrades in secret they will not say anything. Moreover, since the problem in radio part it is very likely that Google is waiting for this fix from Qualcomm, and Qualcomm, as usually, is very slow in this. Moreover, basing on previous experience the chance that Qualcomm will fix it from first shot is about 50/50... This is a world of Nexus. Nothing to do.

Re: Nexus 4 kitkat - bluetooth problem - worst Sonar98 1/4/14 7:32 AM
Like I said before I reverted back to 4.4 after bluetooth problems with 4.4.2.

I just returned from a skiing holiday.
I used my Nexus 4 connected to a Nokia bluetooth headset as a music player all day.
And my smartwatch (Pebble) was connected to my Nexus too.
With the 4.4 KitKat everything worked like a charm.

So Paul, it must be something that has changed with the update from 4.4 to 4.4.2.

Re: Nexus 4 kitkat - bluetooth problem - worst Arie Oster 1/6/14 4:29 AM
I have similar issues.
after upgrade to 4.4.2 the BT disconnected from the platronics headset and disabled. the only way out of this mode is reboot. It is happening twice a day.

Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 1/6/14 7:35 AM
Hi,
 
I found this information on another discussion.  I have followed it and I have not had any further BT problems so far.  I did have ONE of the conditions I call the 'unresponsive black screen' (where the phone appears to have shut off and requires two resets to recover) but my Bluetooth has been working perfectly for almost a week now and I have used it for both phone calls and to listen to music in the car. 
 
One more action I took was that I removed the SIM from the Nexus 4 (I had swapped phones to my old Galaxy Nexus due to the serious problems I was having with Bluetooth).  When I did the wipe data cache procedure below the phone did not have a SIM.  I reinserted it afterward.  Not sure if that was a factor or not, but wanted to mention it in case it is important.
 
Here is exactly what I did (including the SIM removal):
 
1. Shut down the phone
 
2. Remove the SIM
 
3. Restart the phone
 
4. Do a forced shut off by holding the Power button and shutting the phone down and restarting the device
 
5. Clean the cache partition:
 
  •         Hold the Power button for 2 seconds and select Power Off.
  •         Press and hold the Volume Up and the Volume Down and Power keys at the same time for about 10 seconds.
  •         An image of an Android lying on its back will appear.
  •         Press the Volume Down key twice until "Recovery mode" appears on the screen.
  •         Press the Power key to restart in "Recovery mode."
  •         An image of an Android with a red triangle will appear.
  •         While holding down the Power key, tap the Volume Up key.
  •         The Android System Recovery screen will appear. Release all keys.
  •         Use the Volume keys to scroll to "wipe data cache partition" and press the Power key to select.
        The phone will restart.

6. Shut down the phone.

7. Reinsert the SIM.

8. Restart the phone.

Hopefully this will help others.

Good Luck

Bluetooth switching off .Only happened after updating to KitKat .
Re: Nexus 4 kitkat - bluetooth problem - worst johnny_rottenbiller 1/6/14 9:00 AM
Having the same problem: my bluetooth headset disconnects fully at every 2 minutes or so.
Fully disconnects mean: headset goes deaf, I can hear the person talking a few seconds later on the phone, then reconnects again in the headset.
Usually means I loose about 10 seconds on the headset.
Any fix for this?
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 1/6/14 10:37 AM
The phone just froze again.  Same symptom: black screen, not pingable on my wifi LAN, basically a brick.   Recovery requires two hold-downs of the power button.  I believe the first power button hold turns off the phone and the second one does a cold boot.  This started after upgrading to 4.4 and 4.4.2.
Re: Nexus 4 kitkat - bluetooth problem - worst max tsai 1/6/14 7:39 PM
I have the exact same problem on my nexus 4 with 4.4.2 version. Bluetooth drop every few minutes. Google should start taking this issue more seriously, because it might cause an accident when people try to reconnect their Bluetooth while driving. 
Re: Nexus 4 kitkat - bluetooth problem - worst dongyun 1/6/14 9:39 PM
My nexus 4 with 4.4.2 refuses to turn on bluetooth. After reboot, it struggles to turn on with grayish blue color on BT symbol for a while and turns on. But, after sometime in BT speaker connection, BT is suddenly off and manual turn-on does not work. Waiting for fix patch from google.

Identical behavior with my Nexus 4 running 4.4.2.

The temporary solution is to deactivate your wifi while using the Bluetooth. I am sure that google is working on it.

@tiszavolgyi
You do not have to downgrade everything. Do it only for radio. I'm using radio from 4.4 for 3+ week without any problems.

BTW, to whom who want to downgrade radio but do not want to lost data and apps by unlocking boot-loader.
Try to backup your phone first using Helium. It does not require ROOT permission but only connection to PC.
I did not test it yet, but people from XDA saying that it is doing the job. Will test it on my wife's phone before unlock it.

Hi Alex,
Thank you, but could you please explain what do you mean under: "You do not have to downgrade everything. Do it only for radio."

Thank you in advance!
Re: Nexus 4 kitkat - bluetooth problem - worst Alex Sh... 1/7/14 2:48 PM

What do mean by "radio"?

The phone firmware contains a several parts like: bootloader, radio(actually drivers), boot(kernel) and system(ROM). In case of KitKat 4.4.2 the broken part is "radio".
So you can flash only this small part (take it from 4.4.0 factory image) and everything will work.

I had the same problem with Bluetooth failing when connecting my Nexus 4 to my car. Would work for a short time then drop out and had to restart phone to get Bluetooth switched on again.

I tried switching off 5GHz and switching off Wi-Fi completely but problem persisted.

I switched off NFC (settings->more) and it's been stable for the last few days.

Again, for me the music profile is working properly only the CTP is not. More about BT profiles: http://en.wikipedia.org/wiki/Bluetooth_profile

also I can confirm that music transfer by bluetooth not having disconnections
Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 1/15/14 7:58 AM
I have the same exact problem on both a 2009 and 2012 Honda Civic with Bluetooth Handsfree. Bluetooth on my Nexus 4 with KitKat constantly cuts out during calls, and also often turns off requiring a phone reboot to turn bluetooth back on. 
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 1/15/14 9:42 AM
Jamie NYC: Did you try wiping the data cache using the procedure I posted above in this discussion?  If not, I suggest you do so.  I have not had a single Bluetooth problem since I did it and it has been over two weeks.  I have still had two occurrences of the phone going dark and requiring two long-presses of the power button to restart it, but I have had absolutely no problem with my Bluetooth in the car since the wipe of the cache.
Re: Nexus 4 kitkat - bluetooth problem - worst tiszavolgyi 1/15/14 11:01 AM

Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 1/15/14 11:32 AM
I've just tried this, as per your posted suggestion and also suggested by Google customer service. I'll give it a try and report back in a day or so.
Re: Nexus 4 kitkat - bluetooth problem - worst patricia demri 1/16/14 12:36 PM
Same hère! Bluetooth constantly disconnects + battery lasts a max of 8 hours...is there a way to fix those bugs?
Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 1/17/14 11:11 AM
Posting again with latest news:

Google Customer Service advised rebooting into "safemode" to troubleshoot without third-party apps running -- this suggestion did not help. The original problem on my Nexus 4 of bluetooth switching off and only switching back on after a reboot has returned, so essentially both problems I have are not solved.

To recap, since upgrading to KitKat:
  1. Bluetooth randomly turns off and will not turn on unless phone is rebooted
  2. Bluetooth connectivity consistently cuts off during handsfree calls every 1-2 minutes and then reconnects after 2-5 seconds.
Rebooting in safemode actually created a new problem for me, as some widget apps I had loaded with customized data were reset to default, and now I have to spend additional time setting up the custom data again.

Problem not solved. What can Google do to fix these Android fails?
Nexus 4 kitkat - bluetooth problem - worst zkummer2359 1/18/14 9:11 PM
Ever since 4.4.2 I have terrible distortion on BT calls and disconnect at random.  Also cannot place calls by Bluetooth anymore because quality is so bad no app can figure out what I am saying.  This is total crap...my phone was working perfectly before Google forced this update on me, now my most used features are dead...and for what?  No new features I've noticed, slower performance, and the GUI isn't as nice. I appreciate that Google wants to help Ubuntu by sending customers to them...but they don't make a version for the S3, so why are they doing this to the S3???  For the first time EVER I wish I had an iPhone!!!  Heck, my old flip phone was better than this!

Add me to the list. I've only just realized I had a software problem and not a headset problem. In fact I just bought a new BT headset thinking the old one was crapped out. Now I see it was the phone's software.

Google, you there? Reassign whoever is working on this and give it to somebody that knows how to sort it out before someone gets killed f*cking with their phone on the freeway.

Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 1/27/14 10:27 AM
Many many Nexus 4 owners have been posting about the same Bluetooth problems for about 2 months now.  Can someone from Google please post a reply describing Google's position on this and what is being done to address the problem?  I think many of us would be very happy to go back to Jelly Bean 4.3 and leave it at that.  The changes I have observed in my N4 since KitKat have made it worse than it was on 4.3 and I am not talking about problems, just the functional changes.  For example, now I cannot tell from the color of the WiFi and mobile network status symbols whether I have Internet connectivity.  It used to be on 4.3 that if the symbols were not BLUE, i.e. GREY, it meant there was a connectivity problem.  Now it is grey all the time and I can't tell.

Back to the topic at hand:

To be clear and reiterate...  Please can somebody from Google give us some information about what, if anything, is being done or will be done to correct this serious problem with our handsets?

Thanks in advance.....

I'm also suffering the same Bluetooth issue as you describe since updating my Nexus 4 to Android 4.4.2.

I listen to audio using Bluetooth for a few hours each day and the Bluetooth service will often crash and then not work until the device is rebooted. I have identified that it occurs more frequently when Bluetooth and WiFi are enabled at the same time.

I read a previous suggestion about disabling WiFi when it's not in active use and this has solved the Bluetooth issue for me. It's a PITA but at least I don't have to reboot my Nexus 4 twice a day!

Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 1/28/14 6:58 AM
It appears toggling between wifi and bluetooth on/off is essentially the solution of the moment.

Google customer service has suggested I do a complete factory reset; I'm skeptical and hesitant. First they told me to clear the cache, which didn't work, then to boot in safe mode, which didn't work, and now their advice is remeniscent of a Windows tech suggesting a reinstall. I am not going there (yet). Any brave souls out there who want to give a factory reset a try...?

Google also informed me that because my 1 year-old Nexus 4 is out of warranty that I should contact the manufacturer, LG, because Google has no additional means of helping. 

Please reply if you've tried the factory reset. Thanks.
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 1/28/14 7:29 AM
If there were a decent way to back up apps, settings, etc., so that a factory reset is not so traumatic (like with the iPhone), I might try it, but I am with Jamie NYC, a factory reset would cost me hours to recover and I also do not believe it will be effective in resolving this problem.

This confirms what we have observed over the past two months, that Google has turned its back on this problem, shoving it over to LG (how do you say 'fuggetaboudit' in Korean?).  At this point, I think it's time to think about a formal class action.  We have all been damaged by this software upgrade.  No effective action has been taken nor does it appear that it will be taken.  Unless there is some complicating factor I don't know about, offering us the option to roll back to 4.3 would be an effective way to resolve this but we have not been given this option.  Google has been silent here.

What next?

I am also having the random BT disconnects issue using my Nexus 4 with Android 4.4.2.  The bluetooth connection to my headphones drops periodically (every few minutes sometimes) and, a few times a day, bluetooth just shuts off entirely and cannot be turned back on without a reboot.  

  
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 2/1/14 10:15 AM
Happened two times yesterday.  I listened to podcasts all the way to work, no problem (about 30 minute commute) then when I went to the car to go home, noticed the Bluetooth was dead.  I shut down and restarted the phone and it only lasted about 5 minutes before the Bluetooth again went off requiring another restart.  Additionally, as I have mentioned before, the battery life of the phone is about 4-6 hours shorter than before.  Now it runs out of battery before I am ready to put it back on the charger for the night.  Google: If I can be of assistance to you in identifying the cause(s) of these problems, please let me know.  I'd really like to have my old phone back.

Did someone (you?) post how to do a radio 'roolback' (I assume you mean rollback)?  I did a search for both 'radio roolback' and 'radio rollback' and found nothing.

YES, I would try a 'radio rollback' with appropriate instructions.  If it fixes the problem I will be gone.

Since you know of this post, please point me to it.

Thank you.

If I follow the section for the just the 4.4 radio files, will that do it?

Thanks.

@therealzeldar  

Found this: http://freedupthoughts.com/2013/11/how-to-flash-android-4-4-kitkat-factory-images-on-the-nexus-4.html
If I follow the section for the just the 4.4 radio files, will that do it?

Yes,
you need only these commands:

fastboot devices
fastboot oem unlock
fastboot reboot-bootloader
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.84.img
fastboot reboot

the second and third commands you need only if your did not unlocked it before.
and don't lock it after that. keep the bootloader unlocked because you have to flash original radio back before installing next update from Google. otherwise OTA will fail.

and I hope you understand that only you are responsible for what you are doing ;)





 

Re: Nexus 4 kitkat - bluetooth problem - worst Zeldar 2/2/14 6:01 PM
I tried flashing the 4.4 radio image into 4.4.2.  The process seemed to work fine, but I had some other problems afterward....  When I would leave my house, and go elsewhere with the wifi on, the phone would show still being connected to my home SSID (even though I was miles from my home WiFi).  All connectivity was then broken.  If I disabled and re-enabled wifi, it would clear the condition and I could access the Internet via my mobile data.  During my short test period, the Bluetooth did not fail, but the other problem caused me to re-flash the 4.3 Jelly Bean code back on the phone.  Now I get the annoyance of having the 4.4 KitKat update notification wanting to install, but I assume the phone Bluetooth will behave properly again.  I will ignore the update unless Google comes out with an update past 4.4.2.  By the way, IMHO Helium backup is a fairly mediocre solution for backup of your phone.  If you don't back up the apps and photos off the phone (on Google Drive or another cloud or use a rooted backup such as Titanium, you stand to spend quite a bit of time making yourself whole afterward and MAKE SURE all of your photos are safe.  I lost mine.  Backing up on the Nexus 4's internal storage will be wiped out when you do any fastboot operations.

Anyway, I am back to 4.3 and will report back after verifying that everything is working properly again.
Re: Nexus 4 kitkat - bluetooth problem - worst telm43 2/3/14 5:13 AM
My Nexus 4 had the same problem. Since installing Android Assistant( either free or buy) from Google Play I have had no further problems with Bluetooth!

Always use this app to open and close Bluetooth.

Re: Nexus 4 kitkat - bluetooth problem - worst Ed Couto 2/4/14 4:45 AM
I have the same problem in my Nexus 4. In a call at my car, the bluetooth connect, disconnect and reconnect again. All of this after the 4.4 KitKat. How do I proceed? How can I reinstall the Kit Kat from a computer as I used to do in my old Xperia PC Suite? Help me.
Re: Nexus 4 kitkat - bluetooth problem - worst Acropole 2/4/14 4:50 AM
I was using my phone with the blue tooth connecetd with the WIFI disconnected. I have installed Android Assisant and I have done tests yesterday with the WIFI connected and I used my bluetooth, phone and listening music for at least 2 hours and no issue. I think on my side the problem is solved
Re: Nexus 4 kitkat - bluetooth problem - worst Justin Strate 2/4/14 7:38 PM
I flashed my phone back to 4.3 using the instructions below. Sometimes they are a bit spacey but it worked.

Ill try it out in the car Thursday and report back but chances are it will work based on previous posts.

Re: Nexus 4 kitkat - bluetooth problem - worst Acropole 2/4/14 7:45 PM
I am confirming that with Android assistant it has solved the issue. Talk time over 4 hours today with bluetooth and wifi acivated and no issue and disconnection

I am sticking to this
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 2/4/14 9:41 PM
My phone has been working better since I flashed 4.3 back on it two days ago.  I have had one spontaneous reboot while I was using a bar code scanner, but otherwise no Bluetooth failures or glitches.  I have listened to Bluetooth for a total of 4 hours now with no issues.  Battery life is better too.  Just remember that if you unlock the bootloader to load another ROM, it WILL erase everything on the phone.  Until Google releases a fix for KitKat on the Nexus 4, I am going to stick with 4.3.
Re: Nexus 4 kitkat - bluetooth problem - worst cricketsarah 2/4/14 11:15 PM

Re: Nexus 4 kitkat - bluetooth problem - worst Olle Lindberg 2/5/14 1:11 AM
For me bluetooth stops working when the phone automatically connects the Wifi arriving at work. If connecting to a new wifi while using bluetooth is the problem, that could explain why some people seem to have less problems with wifi always turned off.
Re: Nexus 4 kitkat - bluetooth problem - worst Handaloo 2/5/14 8:52 AM
I'm having the same issue. 

Walk to work from London Bridge to Tower Hill in London and some days it will disconnect upto 3 times (like this morning) and required a total reboot to get bluetooth back on. 

Highly frustrating ! 

I've considered going back to 4.3 to see if the issue fixes things, but it seems according to above it does! Will wait for more feedback. 

Have Google shown any signs of knowing about this issue?

Re: Nexus 4 kitkat - bluetooth problem - worst Carlos da Cunha e Silva 2/5/14 11:12 AM
Yes, they are aware and there's even a bug report for it on the android forum. Unfortunately it doesn't get high priority since it's a device bug. I posted a while ago a link to an article with more background information. From all the workarounds posted on this forum, I found the radio downgrade the most promising, it doesn't require a full factory reset of your phone. But until now I saw only one person who successfully did it and one who reported that it caused other issues.
It's very frustrating and I think most people on this forum share the same feeling. Google replied once or twice on this forum that they're working on it.
Re: Nexus 4 kitkat - bluetooth problem - worst Craig Wentzel-Siva 2/5/14 11:38 AM
I have absolutely NO problems after flashing a ROM that uses the 4.4.2 kernel.
Everybody complaining and that has thrown their hands up in despair needs to go get a locked down device and submit.
This is a developer's device, and the rest of the world has fixed this issue.
Do yourselves a favor... Qiut waiting for Google to fix a hardware issue when 5-10 minutes of using Google search will solve your problems.
That is the fix!
By the way, those concerned about OTA.
It's irrelevant with the AOSP platform, because any update will be incorporated into a flashable ROM as soon as it is deemed beneficial.

Good luck,all.

Signing out!

Re: Nexus 4 kitkat - bluetooth problem - worst Vince Anido 2/5/14 11:43 AM
I feel that this bug has been punted to the next version of Android. Assuming the stick to their 6 month cycle, we should see something around April.

I can only assume that this is because of the testing required in another point update, and they feel too few people are having the issue to warrant a separate testing cycle.

Ah well...at least it's not that much longer to wait...
Re: Nexus 4 kitkat - bluetooth problem - worst Toslut95 2/5/14 11:52 AM
Hi. I managed to get Bluetooth to work on my Nexus 4 after upgrade to Kitkat by doing a factory reset. Try it!
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 2/5/14 12:10 PM
If your bootloader isn't unlocked, I don't believe you can flash anything on the phone.  Unlocking the bootloader wipes the phone.  So you can only reflash the radio without erasing the phone if you have unlocked the bootloader some time in the past.  Also, if you lock the bootloader again, you're back at the point where unlocking it will erase the phone again.
Re: Nexus 4 kitkat - bluetooth problem - worst Nexus4OwnerDude 2/5/14 2:03 PM
These kinds of replies make me laugh. We're not allowed to raise an issue if someone finds a way to resolve it by means that require a developers skill set? I must have missed that bit of fine print on the Google site when I purchased the phone. I'm pretty sure Google expected more than just those well versed in flashing ROM's for mobile devices to purchase their phones. This kind of attitude just drives the majority of consumers away and you will end up having to buy a different product when Google can no longer can justify making them for a market that is simply too small (developers only, really?). I'm no technical idiot but I still really don't want to wipe my device clean or render it useless because I don't fully understand what I'm doing.

Pardon my ignorance here but if the fix is in the kernel why doesn't Google simply push out an update? Would that be a huge deal for them? You make it sound pretty simple.
Re: Nexus 4 kitkat - bluetooth problem - worst David McFadyen 2/5/14 2:26 PM
I thought it was just my Nexus 4 that was experiencing this issue. Sometimes the BT can work for about 20 minutes, then switches itself off. It can only reconnect after restarting. I was going to get a Nexus 5 soon but don't think I'll bother.
Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 2/5/14 4:34 PM
Okay, so everyone that's been following this issue, if you haven't already, go read the nice writeup on this issue over at AndroidPolice: http://www.androidpolice.com/2013/12/28/bug-watch-many-nexus-devices-still-suffer-from-assorted-bluetooth-issues/

Personally, my guess is similar to the article author's: there is likely something up with the newer radio drivers for the chipset. There may also be some issues in Android 4.4 as well that are triggering the problem. If part of the issue is with the radio firmware, Google may have to wait on Qualcomm to fix things or they may have to work around the bugs. In such a case, I wouldn't be surprised if they wait for the next point release. Of course, that's all speculation as Google hasn't said much beyond that they were working on the issue. (An update would be really nice, Google!)

So, to try and solve the issue, here is a summary of the options you can take from easiest to most difficult/disruptive:
  1. Unpair and repair the BT devices. Some people have said this seems to fix things.
  2. Disable 5gHz WiFi by setting to 2.4gHz only (Settings -> Wi-Fi -> menu -> Advanced -> Wi-Fi frequency band). This has worked very well for me on the Nexus 4.
  3. Turn off WiFi completely when using Bluetooth. Remember to also uncheck "Scanning always available" from the advanced menu.
  4. Do a factory reset just to make sure that there wasn't some weird BT setting that was corrupting things. You can backup your apps and data without root using tools such as ClockworkMod Helium (http://www.clockworkmod.com/carbon) or plain old adb backup.
  5. Revert to Android 4.3 using a factory image. You'll need to have an unlocked bootloader, so be sure to back up all your data, including SD card if you have to unlock it.

For the more daring, you can try messing with downgrading the radio firmware and kernel.

Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 2/6/14 9:52 PM
Yes.  Thanks to YoungMug for his cogent summary of the courses of action to try to prevent the KitKat Bluetooth crash problem. Thanks also to everyone who provided their anecdotal and empirical inputs that allowed this information to be collected, organized and presented.  I had the same Bluetooth symptoms on my phone back when it had 4.2.  It was fixed in 4.2.2 and 4.3. Somehow the coding that resolved this problem must have gotten removed or modified in the latest KitKat causing the same Bluetooth symptoms to return.

I have also flashed my phone back to 4.3 and it is working normally again.  Why wouldn't it?   It was working fine before the KitKat OTA.
Re: Nexus 4 kitkat - bluetooth problem - worst Tiziano Fagni 2/7/14 3:14 AM
With my Nexus 4 I had issues during bluetooth calls while driving my car. By changing the settings of Wifi (to only 2.4 Ghz frequency) as suggested in  http://www.androidpolice.com/2013/12/28/bug-watch-many-nexus-devices-still-suffer-from-assorted-bluetooth-issues/,  the frequent bluetooth disconnections have gone away and now everything seems to work correctly.
Re: Nexus 4 kitkat - bluetooth problem - worst craigster_zero 2/7/14 11:14 PM
Disabling WiFi makes the bluetooth headset usable for me.  Its not a happy situation, but its far better than nothing.

I have the same problem with my Nexus 4 and Plantronics Voyager Pro+ headset: the headset will be disconnected after 30 sec to 3 min of conversation.  sometimes i hear a buzzing sound for ~20 sec from the headset before it disconnects.  unlike some others, Bluetooth is not disabled.  i'm able to reconnect by pushing the headset button usually used to hangup or make a call.

For those who are thinking the problem is bluetooth in my car, it's not.  i have a '97 BMW and it doesn't have any Bluetooth.

Some folks have WiFi also has problems and that disabling WiFI allows Bluetooth to work and vice versa.  That solved the most immediate problem for me.
Re: Nexus 4 kitkat - bluetooth problem - worst Alex Sh... 2/9/14 10:08 AM
Did an experiment and installed latest "broken" .98 radio and Cyanogenmod 11. No problems so far. BT, WiFi, everything is working perfect. So, looks like the problem is not in the radio, but in ugly stock rom. Will stick to the CM11. At least this community is providing a nice support in their forums, and fixes are coming quickly (+ more features) :)

Nexus 4 kitkat - bluetooth problem - worst Matthew Gully 2/9/14 12:56 PM
My friend had the same issues with the Bluetooth.

After reading many posts and blogs saying that it might be an issue with conflicting WiFi signals we installed an app called FXR WiFi fix and rescue, ran it and followed the on screen instructions and rebooted the device.

THIS DID FIX THE PROBLEM AS OF THE TIME OF POSTING!

I hope someone finds this helpful and it fixes there problem too.

This is exactly why Google couldn't care less. Even if you believe they aren't screwing things up on purpose, it is inexcusable for Android to not operate properly on a device that is supposedly manufactured for Google. If they're not testing on the Nexus, what are they testing on?

The hilarious part to me is that on my Nexus 4, the instant the Bluetooth dies, Google Music starts playing Johnny Cash. WTF? Now I disabled Google Music; next will it email all my contacts Johnny Cash lyrics?

When my Bluetooth dies there's no way to get it back without turning the phone off and on again (thanks for not providing a reboot option, you geniuses). I've turned off 5 GHz Wifi but I'm afraid I'm not willing to do what Youngmug suggested. 
Re: Nexus 4 kitkat - bluetooth problem - worst Pierre-Alexandre Sicart 2/25/14 5:11 PM
Turning off just 5 GHz doesn't work. Turning Wi-Fi off entirely does work, but now I'm facing surcharges because Google+ used half of my monthly 3G quota in under a week, even though I haven't ever used it! (And that's with the "don't back up photos when not on Wi-Fi" and "don't back up videos when not on Wi-Fi" options selected.) When BT goes dead, the only option is to turn off the phone entirely. What a mess. And what a spiteful silence from Google. 
Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 2/25/14 5:22 PM
Itsa, I've seen dropped bluetooth cause spontaneous audio playback a few times, sometimes with a different audio player. I've also seen it happen with wired headphones, so I don't think it's a Bluetooth-specific issue.

Pierre-Alexandre, The 5gHz "trick" seems to work on some devices, but not others. The only thing I can think is that it's due to different chip revisions. My baseband version shows as "M9615A-CEFWMAZM-2.0.1700.98. Is yours different?

Google, did mention they were investigating the issue, but they certainly have been quiet lately. A shame too, since I really don't want to use Samsung when I upgrade as I really don't like the physical buttons nor TouchWiz. HTC is interesting, but I'm not thrilled with their "skin" either. It sure would be nice for a minor update to know this issue hasn't been forgotten. Maybe even I will have to look at options outside Android for my next device, even though I really don't want to.

For now, I might try using CM11 with the older radio that at least one other person reported as a working option. Couldn't hurt and only takes the time for a backup and restore...

for what its worth, I've noticed about the same thing on my handset experiencing the Bluetooth problems that are solved by disabled WiFi -- the music player starts spontaneously (i don't use it at all so it wasn't me!).

but that's not a big issue -- unlike dropping my Bluetooth headset connection while i'm in the middle of a voice call!

Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 2/26/14 7:59 AM
Finally gave waiting for the people at Google to get their act together.  A few months ago I decided to give Android a try. Figured a Nexus device would be supported and get updates quickly like I used to on my Apple device. After having nothing but problems since updating to Kitkat,  now I can definitely say this experience left me well with "a bad taste in my mouth" The Nexus 4 was(I have killed it) my first nexus device and definitely the last.  Google does not post any updates on their bug fixes and for such a big company they leave people out in the cold.  As of 5 minutes ago I officially took a hammer to that piece of trash Nexus and walked over to my local Apple Store dropped my $$ and got an iPhone 5s.  At least with Apple I get updates and something as simple as Bluetooth connectivity works.   For the rest of you good luck and god speed. At least now I wont be pulled over and given a fine because im holding my handset while I drive, I can use my handsfree with no issues in my car.
 
P.S. Google you will get the remains of the nexus 4 in the mail soon, please give it a proper burial on your end.

My baseband is M9615A-CEFWMAZM-2.0.1700.84 , the 5Ghz trick did not work for me.

I've been plenty happy after flashing back to 4.3 with only minimal issues (that I had at that version before anyway).

I've never had a flawless smartphone (Apple or Android) so I guess this doesn't get under my skin as bad as some others.

Re: Nexus 4 kitkat - bluetooth problem - worst iomme 2/26/14 8:41 AM
I don't think that going back to 4.3 is a solution. 4.4 was solving issues from 4.3, for example an issue related to Google Services that were draining battery so that I was forced me to restart the device every day. As somebody was saying previously, if we had a restart feature everything would be easier
Re: Nexus 4 kitkat - bluetooth problem - worst Justin Strate 2/26/14 8:46 AM
I think it depends on if you had issues or not. My Google Play Services works fine and my battery lasts all day on 4.3.

That being said, between work and home I have ample access to chargers if I need them and would rather have Bluetooth working for me than more battery life (if it was an issue)

I was pretty sure Google Services was updated separately from the OS (app is here) so its possible you wont have any issues after flashing to 4.3 and then making sure all your apps are updated.
Re: Nexus 4 kitkat - bluetooth problem - worst Homer Dong 2/26/14 8:48 AM

Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 2/26/14 8:50 AM
To flash the factory images for the Nexus devices, follow the instructions at http://www.androidpolice.com/2013/11/14/android-4-4-kitkat-factory-images-and-binaries-are-up-for-nexus-4-all-variants-of-nexus-7-2012-and-2013-and-nexus-10/

Yes, they are for 4.4. Just substitute 4.3 and you'll be fine. It's the exact same steps. Follow the process, read everything carefully and it will be very difficult to permanently break the device.

Some things to keep in mind:
  • You will need to wipe your phone completely, so don't do the edit in step 3 of the instructions. If you do the edit, you'll go into a boot loop when you try to turn on the device and will need to factory reset it anyway.
  • Your phone bootloader must be unlocked to do this. You can tell by the little lock icon at the bottom on the "google logo" screen when you first turn on the phone. Don't see one? It's locked and you'll need to do the unlock. You can re-lock when you're done if you would like. If you "rooted" the phone, you're probably unlocked.
  • You will lose data. There isn't much way to avoid this. Use a tool like Helium to backup applications and their data, it doesn't need root access. You can also use "adb backup" directly. If you have to unlock the bootloader, backup your data partition (/sdcard) manually as that will be wiped.

Ed, hope you don't mind Apple not saying much either. They're kinda known for their secrecy. Heck, the latest SSL security issue for OS X had no communication until the update was pushed out. It's just trading one silence for another.
Re: Nexus 4 kitkat - bluetooth problem - worst Justin Strate 2/26/14 9:10 AM

Exactly. + In case of Nexus you have a huge range of custom roms and you are free to flash anything you want to, including ubuntu ;). But with an iPhone you are limited and if something doesn't work - you are stuck. (+ double $$$ for the same functionality or even worst)
Re: Nexus 4 kitkat - bluetooth problem - worst iomme 2/26/14 9:21 AM
The problem I had in 4.3 (a known issue) was that after more or less 24 hours, Google Services started draining battery, that's why it was necessary to restart the phone. In my case it wasn't even possible to use slow charger because the phone was consuming more energy than the charger was supplying. With 4.4 the problem had been fixed; it might be that the fix was back-ported to 4.3
Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 2/26/14 9:22 AM
Justin, flash-all.bat (along with flash-all.sh) is inside the zip you download of the factory image. Don't use any other one.

It really is aggravating to read about this annoying 3-month old problem I've been experiencing on the Nexus 4 with KitKat, Bluetooth and Wi-Fi still not being addressed properly by Google.

On my Nexus 4, I have to completely disable WiFi whenever I get in the car to prevent my car's BT connection dropping every couple of minutes during a call. What is strange is that the BT connection drops, and reconnects automagically like the BT radio just cuts out for a moment, and then comes back on and reconnects with the car. The call itself doesn't get dropped.

I tried a variety of things described in this thread including wiping the device cache and setting the WiFi to 2.4Ghz only. And the only thing that seems to have worked so far is to completely turn off WiFi completely whenever I need to use BT. Terribly inconvenient.

At least it is working for you without Wifi. I tried everything mentioned in this forum, but nothing seems to be work for me. :((( 

I am also really disappointed with this. I advised many of my friends to use Android phones (especially Nexus) instead of iOS, they hate me already... I cannot believe they are not able to fix it in 3 months... 

I do not want to downgrade to 4.3, because I just do not want to spend another two days to set up everything I have, install all the applications, connections etc... If I would know months ago that I won't be able to use BT for more than 3 months, maybe I would downgraded. Really hard to decide to do it or not now, I am sure if I do it, they will fix this problem in a few days. This used to happen with me...

Had anyone switched the android runtime to ART, because since I did that I no longer have any problems with Bluetooth using it every day for around two months
Re: 5Ghz WiFi off did not work, WiFi off completely has been working so far... Terry Sykes 3/13/14 2:18 AM

Yesterday I gave up on waiting for Google to fix these issues. After reading several successful reports of users downgrading the radio I decided to give it a try. It seems to have worked for me, no more disconnects or bluetooth crashes (so far). I have noticed no unwanted side effects of the downgrade. If you want to try this yourself you need to have unlocked your bootloader (this is already done if you have rooted your phone).  If your bootloader is locked then you may want to wait for the official fix as the unlock procedure will wipe your phone!

If your bootloader is unlocked:-
1. Install the Android Drivers and SDK
2. Download baseband or factory images that contain baseband you want (I got mine from http://d-h.st/cIJ which is from Nexus 4 Android 4.3)
3. Copy the modem.img file in the zip from the above link to the platform tools folder (default is C:\adt-bundle-windows-x86\sdk\platform-tools)
4. Open cmd in platform tools folder by shift + right click and selecting open command prompt here
5. Connect phone to computer and check if its connected by typing 'fastboot devices'
6. If it lists the device, flash radio by typing 'fastboot flash radio modem.img'
7. Reboot the phone by typing 'fastboot reboot'

If your phone is rooted you could try a simpler method using a new app called Nexus 4 Modem Flasher in the Google Play store - you'll want to choose stock radio version 0.84. I can't vouch for this simpler method as I only learned of it after I had done the manual method.

As ever, please note the usual disclaimer - if your have issues or brick your phone don't come yelling at me. You do this entirely at your own risk.

Hope this helps!

After your suggestion I tried this also but unfortunately this made no difference to me. The only method that reliable works for me is to always switch off the wi-fi when connecting to the BT in my car.

I realize that I could roll back the radio to an earlier version, but I'm hopeful (but getting increasingly disapointed) of a proper fix coming from Google that doesn't require me to do this. 

Come on Google, do't let us (your paying customers) down, this has gone on for far too long now!! 
Re: Nexus 4 kitkat - bluetooth problem - worst paul asdagi 3/18/14 7:04 PM
Yep same issue but mainly when on a call and screen locks...shortly before disconnect you hear what sounds like DTMF tones.

Re: Nexus 4 kitkat - bluetooth problem - worst Nexus4OwnerDude 3/19/14 10:35 PM
I have a Plantronics Voyager BT headset and I disable all WiFi when I am mobile (in the car) and have had no disconnect problems with my Nexus 4 which I have not rooted or otherwise tweaked. I turn WiFi on when I return to my office. I can use both WiFi and BT as long as I do not change locations. This confirms for me that it is the changing of WiFi or searching for WiFi that interferes with the BT connections but I'm not an expert here and really it doesn't matter to me. I just need it to work. I don't use WiFi in the car anyway.

The only problem is when I forget to turn off WiFi when in the car and I have to stop to turn it off. I've tried doing it while driving and it's just stupid and not worth the risk. It will be nice to see an update that fixes this sooner than later.

Re: Nexus 4 kitkat - bluetooth problem - worst Chris_Harvey 4/1/14 5:36 PM
Same problem here.. HBS730 and a Nexus 4, worked perfectly when I used to run CyanogenMod 10 and prior, as soon as I went to CM11 I started having in call issues which drove me to reloading my phone to Google stock 4.4.2.  Sadly the time wasted reloading was all for nothing, seems to be related to 4.4 as mentioned here.. I am very hands on in my line of work, sucks now that my bluetooth semi works, no problem with playing music though..
Re: Nexus 4 kitkat - bluetooth problem - worst Justin Strate 4/2/14 6:34 AM
I've been running stock 4.3 for awhile and over the past 2 weeks dropouts on phone calls have become more common. I can't tell if its the combined use of Pandora at the time or something else.

I will be avoiding Pandora use in the car for the next 2 weeks and see if it helps.

Strange issues but still better than 4.4 overall.
Re: Nexus 4 kitkat - bluetooth problem - worst chunnih 4/4/14 3:38 PM
i was having the same problem with the Bluetooth on my Nexus 4, I rebooted it and turn on the blue on the cell and paired it with the truck radio, and its working, don't really know what i did but
its working now, i don't dare turn it off, have the cell charging and i still can hear the music from the truck, at least something is going right for me today,  im happy,  good luck

Re: Nexus 4 kitkat - bluetooth problem - worst Ansgarr 4/17/14 1:15 PM
Paul,

Can you provide an update on when this bluetooth connectivity issue will be patched?

Since this issue has been opened since November 2013 without resolution from Google, I'm beginning to wonder if a solution will be provided at all.
Re: Nexus 4 kitkat - bluetooth problem - worst NW Dave 4/25/14 4:54 PM
Same problem here. Only solution that has worked for me is disconnecting WiFi before starting Bluetooth. Used to work fine.

Apparently, the coding skill at Google does not exist. Or worse, the skills are there, but they don't care.

Re: Nexus 5 kitkat - bluetooth problem - worst Renaud T 4/29/14 6:22 AM
I am also having the bluetooth disconnects issue using my brand new Nexus 5 with my car phone kit. Android version is 4.4.2. The bluetooth connection to the car kit drops after 30 seconds and most of the time doesn't reconnect at all. It happens few times that it reconnected after 5 seconds. The car kit used to work perfectly well with other Android phones.

Needless to say that it is very annoying...

Re: Nexus 5 kitkat - bluetooth problem - worst dbkc397 4/29/14 7:57 AM
This is due to the 4.4.2 Kit Kat upgrade. The Bluetooth does not work reliably in this version. I have a Nexus 4 and I had to flash it back to 4.3 in order to make it work as it should. After I updated to Kit Kat it broke the bluetooth and I was never able to get it to work reliably again until I flashed it back to 4.3. Google has completely dropped the ball and has not offered any fixes or updates. They don't even acknowledge that this is an issue. After Im done with this phone, Im going to an IPhone and will never look back to Android again. I considered the Galaxy S5, but after I heard that it was running Kit Kat, ..... No Way!  I want a phone that works. Not one that is sold to me then not supported at all. Like Google has done to me. They have just gotten to big and just dont care anymore. Not that Apple has not gotten to big, but at least I could take the Iphone into an Apple store and get support. Unlike Google who has isolated themselves from every user in order to not provide support for their inferior products

@dbkc397
If you are expecting for better support from Apple - you will be very surprised how bad is it. Them have the same problems as in Google and Apple store will treat you in same way as google support is doing via phone. You will get standard solutions like, restart, reset, send it back. Nothing more. But going with Apple and joinin the army of hamsters fans you will pay double for a crappy jailed device, you will hooked with extortionate paid services, you will lost many features and flexibilities and your device will looks like an ugly brick, even if you put it into case with rhinestones. But no one can stop you, everyone learns from their mistakes.

Re: Nexus 5 kitkat - bluetooth problem - worst Nexus4OwnerDude 4/29/14 10:28 AM
Talk smack all you want about Apple devices. About how their support is no good and so on. Where do I take my Google phone for support? T_Mobile? Come on. These devices and the entire industry is facing an increasingly difficult task of keeping all the moving parts working together. It's amazing any of it works when you think about it. Look how many companies, organizations and developers are involved. Still it is very frustrating. I'm one of those that initially liked my Nexus phone. It appears to offer a hell of a lot for the money. But I will say that I'm tired of things not working when I need them most. IN THE CAR WHEN I'M DRIVING. I can make anything work when sitting at my desk. I'm just no longer a Google customer it seems. Who cares right?

So what does a Nexus customer like me do? I don't really want to go back to the iPhone. I could try a Galaxy S5 but I don't like idea of having more Android pain and suffering. I had almost no pain with my last iPhone until the little button started to give up. The software worked. It was wasn't the fastest phone, or the best display or anything else but it always worked in the ways I needed it to. I never had to think about breaking it out of jail, rooting it, or otherwise screwing with the thing. I really just wanted something that worked but different than all the other "hamsters" had. I love innovation. Problem is all the other hamsters can at least use their phones and navigate to their destinations 99% of the time without wanting to pitch their phone out the window of the car.

But wait, maybe I'm just a dumbass that should find an old flip phone and paper map. Hmmm, that sounds so good right now. I could toss out 10 power adapters and stop spending time every week looking for new Apps that fix problems on my phone, tablets and BT headsets. How long before we can't get ice out of our refrigerators because the last release of the OS is f'ed up?
Re: Nexus 5 kitkat - bluetooth problem - worst Alex Sh... 4/29/14 10:57 AM
It is really funny. People buying developer phone in order to get latest updates for cheap and then blaming the Google in their wrong decision.Yes, Nexus is developer phone, and since it gets first OS updates it may also receive bugs. If you do not want that - do not take Nexus. Samsung, LG and many others have tons of good and stable devices. But if you does - you should know what and how to do in case of problems. Nexus by itself is flashing frendly devices, so flash something else. In my case i moved to CM11 and more than happy.
Re: Nexus 5 kitkat - bluetooth problem - worst Nexus4OwnerDude 4/29/14 11:38 AM
Yes, Alex. So I've heard. I bought a Developer's phone. I do wish it had been marketed as such.

Google Nexus 4 - The Developer's Phone

I don't think I would have bought it at any price knowing that. Oh well. That is really my biggest complaint here is that I bought a Dev phone and was either too stupid to figure that out or maybe it was not as obvious as it should be. I want anyone buying a Google phone to fully understand that they may need to be WILLING and ABLE to play developer with it. I'm betting a lot of their phone customers don't know that. It's a good device for those that do have the inclination. As I think about it I probably have nothing to lose at this point. I could slam 4.3 on it and if I fail I go buy a new phone. Worse case I'm without a phone for a day or two. Time to stop whining and fix it or move on. Alex, thank you for kick in the pants.
Re: Nexus 5 kitkat - bluetooth problem - worst Alex Sh... 4/29/14 11:52 AM
@Nexus4OwnerDude
Oh, sorry if i made you upset. I'm the same customer like you. And initially i also complained on service and phone. But then started to play with ROMs and found it is not so terrible as looks. Moreover i got many extra features that stock ROM doesn't provide. So, if you already descided to go on this way, dont go back, dont install 4.3, try with CyanogenMod 11. It is the same 4.4.2, but with all bug fixed plus some extra. Good luck.
Re: Nexus 5 kitkat - bluetooth problem - worst Nexus4OwnerDude 4/29/14 2:19 PM
Not upset just venting my frustration. I appreciate your views. In fact my phone is now running CyanogenMod for the Nexus 4!!! I backed up my photos but the rest I can recover from the cloud. So far so good. I liked all the stuff I read about Cyanogen and the fact that they provided an installer was all I needed to convince me to try it. Congrats to all the people that work on that. It is slick and worked very well. Maybe I can keep the old Google phone after all. Ha.

Tomorrow I will find out if things work any better on a long drive I have to make. Fingers crossed. Thanks Alex for suggesting the Cyanogen at just the right time.
Re: Nexus 5 kitkat - bluetooth problem - worst tiszavolgyi 4/29/14 3:27 PM
Hi AlexNexus4OwnerDude,

Do you have the same Bluetooth issue after installing the CyanogenMod? I am just hesitating to install it or not, since 4.4.3. suppose to come soon...

Thank you!
Re: Nexus 5 kitkat - bluetooth problem - worst Nexus4OwnerDude 4/29/14 3:57 PM
I will tell you later this week. Should be able to report on this by Thursday. I will test by leaving my WiFi enabled as I will travel the same roads that have previously been a problem.

The other nice thing I noticed about my Cyanogen install is that all my Google Play apps are automatically being reinstalled. It's still pulling them down. Nice that I didn't have to do them one by one. It steps you through your Google account stuff assuming you have one. It really was very smooth. I expect I will have some things I have to deal with though but it won't be rooting and unlocking by following various postings from all over the internet.
Re: Nexus 5 kitkat - bluetooth problem - worst tiszavolgyi 4/29/14 4:42 PM
Thanks a lot, appreciate your feedback! I am really curious Bluetooth disconnecting issue when you make a call. This is my biggest problem, the music works fine for me most of the time. Usually it is disconnecting just in every 20-30 min with music, while during phone calls almost in every minute.

Thanks again!

Re: Nexus 5 kitkat - bluetooth problem - worst Alex Sh... 4/29/14 4:45 PM
I'm using BT in car, two parallel connections, one is to car itself for call only ((my car is old Mazda 5 supports only calls over BT)) and second connection to BT adapter connected to AUX, for a music. Both are working for no problem everyday for 20-40 min trips. WIFI in car switched automatically to AccessPoint mode (by profile), so my daughter connects to my phone from her Nexus7.
But before i switched to CM11 the BT connection was dropped every time, every 2-5 minutes and can not be enabled without reboot.
Re: Nexus 5 kitkat - bluetooth problem - worst tiszavolgyi 4/29/14 5:02 PM
Thanks a lot, it is convinced me, I am going to install it ASAP :) Will report if it works for me as well. 
Re: Nexus 5 kitkat - bluetooth problem - worst Nexus4OwnerDude 5/1/14 1:52 PM
I tested yesterday and I still have the same BT connect/disconnect problem with WiFi enabled. I had to turn WiFi off. Oh well. I am otherwise pleased with the CyanogenMod OS. I've not thrown my phone out yet. The voice dialer worked better. A lot better. I'll see how it goes on my return trip before I make a final decision. If all I have to live with is disabling WiFi in the car I can do that. I just need navigation and BT to work properly. If it gets fixed with the next release great. If not, I will move on.
Re: Nexus 5 kitkat - bluetooth problem - worst Alex Sh... 5/1/14 2:19 PM
@Nexus4OwnerDude,

Ohh, very sorry to hear this.
But if it works for you with WIFI disabled and you are using BT only in Car, you can configure it to turn off WIFI when BT connects and turn on when disconnects automatically , using profiles.

Go to Settings->Profiles.
Create profile "Car IN", edit it, put check mark near Wi-Fi, press on it and select "Disable" -> "OK"
From bottom menu select Trigger option (middle option, the icon looks like map pointer), then select your car's BT profile, and choose "On connect".

Create another profile "Car OUT", edit it, put check mark near Wi-Fi, press on it and select "Enable"->"OK"
Then select Trigger option, select your car's BT profile, and choose "On disconnect".

So now your WIFI will be enbled in opposite to BT and vice versa.
Hope it will help.

I agreed with opinion of the users. I have connected my Jabra Superem and its has the following issues.
1- connection and disconnect by it self.
2- Phone it self turn off the blue tooth and when you try to switch on it doesn't respond. The only option to turn off and switch on and after the issue remain.
3- Software/ hardware is not mature and no response from both the companies.
Bad ethics

I configured my phone to turn of wifi when BT connects to my BMW. I does not disconnect any more, but people hear me breaking up all the time. I called myself with wireless phone over BT, and I can confirm that my voice disappears after few seconds, then comes back and then off again. I am pissed big time.

Re: Nexus 4 kitkat - bluetooth problem - worst ukHAIRYMAN 5/10/14 2:28 PM
Hi guys
I am on my third new tablet in two weeks. Two nexus 10s and now a Samsung galaxy tab pro 8.4 . I returned the first 10 due to slow erratic Wi Fi  and no bluetooth connection possible after kit kat upgrade  it was fine on jellybean tried a second one (fool) same scenario.  Samsung support said  after thesecond nexus 10 under no circumstance should you allow auto updates to kit kat or the  connectivity will go!! Kit is not recommended for older devices. Both were brand new out of the box nexus 10s!
So I got a Samsung galaxy tab pro 8.4 which  has a fantastic screen the same as the nexus 10 but is a better size for me.
Also it came supplied with kitkat so I assumed  ( fool) it would have fully approved for firmware/hardware compatability.

No real surprise but tab pro 8.4 has the brand wifi issues as nexus 10.
I have tried all the above with three routers and two phones on BT. I only get erratic wifi at 12 maps maximum at very short range ( same or next room to routers. Tried bt and wifi separately  as I understand there are issues with running them together. They don't work properly separately, , in fact BT only ran once for me.

Nexus 10s worked fine on 4.2.1 and kitkat is the culprit.wifi connected at 20th on 5 or 2.4 get  after kit barely manages 12meg and cuts out.
 
All Google helpline says is reboot, reset and send back.

At least Samsung helpline are honest and sat kit kat is dangerous to install on nexus 10.

I AM A VERY  VERY UNHAPPY GOOGLE SAMSUNG CUSTOMER. I am awaiting a refund on the second nexus 10 and will be taking the lovely to handle and look at tab pro 8.4 back to John Lewis for a refund.
Google surely has the resources to fix these sort of problems in days not mounths , they make Microsoft look superb.

Is there any chance of a fix for this universal Samsung / kit kat issue.

An  I-pad mini retina looks like the option  at about the same cost or maybe Ishould save money and aggravation and get an older 2012 nexus 7 which seem solid due to older android version.

Any ideas anyone!!!  
This has been a terrible introduction to tablet computing for me , I wish I had stuck to my android gingerbread Sony phone and windows pc.

My three year old sony phone manages 72 meg connections on all three routers at 20mtre range whereas the kitkat based nexus and tab pro struggles even at 4 try range.

Regards

Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 5/10/14 4:03 PM

Re: Nexus 4 kitkat - bluetooth problem - worst ukHAIRYMAN 5/11/14 12:41 PM
I cannot even get my bluetooth to connect more than one time in three. I even tried it with the Wi Fi  off it was no better. The wifi only connects at slow speed with any router on 2.4 or 5 ghz . Both nexus 10s were the same and now the galaxy tab pro is the same. Must be defective software as there are thousands of posts on many forums with kit kat connectivity faults.
I don't know which Wat to go return the tab as defective or hope a kit kat upgrade is due soon. It looks like kit kat has been defective since 2013 though. It's now May 2014 and one of the largest it companies cannot fix these faults.

Strange that the product team still does not recognize the importance of this fix. To me it looks like they just don't care. Count how many people have posted their comments here - I bet there will be hundreds... 

I managed to solve this issue by updating my phone's firmware to Cyanogenmod. The latest version (v 11) works great, I've never experienced any connection drops in 3 months and I'm using it daily. Hope this might help someone.
Re: Nexus 4 kitkat - bluetooth problem - worst Calum Lawson 5/12/14 12:59 AM
This has me concerned, I expected that the numerous issue posted here about a bug that was introduced was going to be resolved in the much anticipated 4.4.3 update that, by all accounts, is imminent. One of the touted fixes that this contains is fixes for various Bluetooth issues.

Whilst I realise that until 4.4.3 does arrive there will be no official confirmation of its contents, I'm now concerned that this bus hasn't even been considered for a fix, let alone fixed by the product team.

Nearly 6 months with a fault that isn't just one that only occasionally manifests itself, but is one that can almost be made to occur at will and no prospect of a fix doesn't seem like the level of service we should be expecting from Google. It's almost as if there is no desire to fix it and they'll simply let it slip to the end of the "18 months worth of updates" that gets quoted.
Re: Nexus 4 kitkat - bluetooth problem - worst tiszavolgyi 5/12/14 12:56 PM
After waiting months for a solution I decided to install Cyanogenmod as it was suggested by few users. Be honest I was not happy about it, it is always dangerous to change your ROM and most of the times it is a headache, something always go wrong. I WAS REALLY SURPRISED HOW EASY WAS TO INSTALL CYANOGENMOD, nothing went wrong and finally I am able to use Bluetooth without problem in the last few days. I need to test it out if it is working well with wifi connection as well, I will report about it. 

Actually I am really satisfied with this ROM, more customization, everythings run well so far, I do not have any issue at all.
Re: Nexus 4 kitkat - bluetooth problem - worst Nebojsa Zdravkovic 5/12/14 10:54 PM
Good for you - I tried installing CM11 and I got stuck in a bootloop. I also heard other people having random failures on various phones with CM11. So please, do some more testing before declaring victory.
Re: Nexus 4 kitkat - bluetooth problem - worst ukHAIRYMAN 5/12/14 11:19 PM
Hi Callum thanks for the reply I have looked at the forums here and elsewhereand concluded there is a major fault with Kit Kat with most hardware regarding the BT and WiFI . With current Samsung tablets there are reported WiFi bt antenna faults with it placed right next to the place you holthem in portrait. You therefore absorb the radio signal with yr hand. Try xda website. Sorry I cant cut and paste the link with my old tiny smartphone, which works fine on android 2.3.4 with WiFi at 72m connection at 20 metre range.
My the two nexus 10s I tried failed beyond 5mtrs range on WiFi when upgraded to 4.4.2. I tried a Samsung tab pro 8.4 just the same even though it came with 4.4.2 as standard.
Most other make forums for other makes report bt and WiFi issues with kk.

I phoned Samsung tech assist a few times their only solution was to collect it from my home

Re: Nexus 4 kitkat - bluetooth problem - worst ukHAIRYMAN 5/12/14 11:35 PM
Sorry hit the post button on me tiny phone!
All Samsung suggested was to collect it and fix it, good on them but bear in mind I had already had two other Samsung tablets in three weeks with the same issue when tried on three diff routers. Also bt wouldnt work at all with WiFi turned on at the same time.
 I have therefore returned the tab pro as it was still in the UK return time limit for goods brought on the net ( distace selling regulations) plus I had little faith in samsungs fix. A prevoius call to S resulted in them saying you should never upgrade to kk on jb units due to the huge number of calls generated reporting errors. A sudden outbreak of candour!
I loved the tab pro the screen and size was great but a tablet without good bt or WiFi is like a house without a front or back door.

I really think kk and a lot of hardware dont work properly. Bear in mind my three tablets tried were all new and had no third party apps installed. I had turned off various

Re: Nexus 4 kitkat - bluetooth problem - worst ukHAIRYMAN 5/13/14 10:30 AM
Sorry to break this post into bits but I have a busy schedule. I really liked the Samsung tab pro but these seem to have the same hardware firmware issue as nexux10s . Has anyone has anyone any recommendations for a fairly highend android midi size tablet that just works.
 also has anyone else had manufacturers saying not to upgrade the os as it might cause failures as Samsung said to me.
Regards
Re: Nexus 4 kitkat - bluetooth problem - worst charlie#nexus4 5/18/14 5:35 PM
I also have a similar problem too. I have a bluetooth headset which works perfectly fine before upgrading to KItkat. 
After upgrade, my nexus 4 disconnect bluetooth connection in the middle of any point and switch to built-in speaker ( no particular pattern has been found what point of usage drops the connection )  and do not turn back on unless I manually turn off my phone completely and restart it again. 
please fix this.. it really bothers so much!!!!!!!!

Re: Nexus 4 kitkat - bluetooth problem - worst cricketsarah 5/19/14 5:17 AM
I now have the problem that if I switch the wifi off to use bluetooth, I then can't switch it back on without restarting the phone.  Therefore, I'm incurring more data charges because I don't realise I haven't reconnected.  Come on google - we have 2 nexus 4's and a nexus 7 in this house, do you really want to lose our business because I'm close to going back to apple, which I really don't want to do, SO SORT IT OUT!!
Re: Nexus 4 kitkat - bluetooth problem - worst Roliza Mascarenhas 5/19/14 12:52 PM
Did you find a solution to your blue tooth problem? Ive been facing the same problem with blue tooth when I drive?
Re: Nexus 4 kitkat - bluetooth problem - worst Roliza Mascarenhas 5/19/14 12:56 PM
Hi Claire,

I wanted to check if there was any fix to the blue tooth issue that people are experiencing? I am faced with the same issue and it is frustrating?


Re: Nexus 4 kitkat - bluetooth problem - worst Devan Barwood 5/22/14 11:02 PM
Experiencing the same issue.

My whole car system crashes and goes into safe mode.
Re: Nexus 4 kitkat - bluetooth problem - worst Terry Sykes 6/4/14 2:07 AM
I upgraded my Nexus 4 to 4.4.3 but still experience bluetooth dropouts :(
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/4/14 12:34 PM
This is very disappointing to hear.  Did you load the official 4.4.3 release?  I also have a Nexus 4 that I downgraded to 4.3 several months ago.  I have been anxiously awaiting 4.4.3 in hopes it would fix the Bluetooth problem.  If it does not, then what problems does it fix?  Bluetooth drops requiring a restart is the most serious flaw I observed in 4.4.2.
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/4/14 1:01 PM
If anyone else is willing to load 4.4.3 on your Nexus 4, please report back on your results with the Bluetooth.  It would be good to get additional data points.  Thanks.
Re: Nexus 4 kitkat - bluetooth problem - worst Sonar98 6/4/14 1:10 PM
I too had the bluetooth problems. I downgrade to 4.4 and everything was working fine again.
Later I reinstalled the 4.4.2 OTA update again and my bluetooth kept working without problems.

I just installed the 4.4.3 update and it looks like it is still working fine for me.
Re: Nexus 4 kitkat - bluetooth problem - worst Calum Lawson 6/5/14 1:02 AM
My phone updated OTA from 4.4.2 to 4.4.3 yesterday evening, I then had to do a two trip in the car and the phone never once dropped the Bluetooth connection to the car durig the journey, likewise on my journey into work this morning, no drop out. Previously I was having to use the workaround of switching off wi-fi when a Bluetooth connection was being made.

It's looking promising so far.
Re: Nexus 4 kitkat - bluetooth problem - worst Bert De Haes 6/5/14 1:16 AM
Same for me after the update. Before, with  bluetooth and Wifi on, it crashed when both were used. After update, I tried again : no crash yet ...


Re: Nexus 4 kitkat - bluetooth problem - worst Paul Younghusband 6/5/14 4:38 AM
OK,  seems they have fixed the problem. I will do the update now and try it out in the car on the way home.
Re: Nexus 4 kitkat - bluetooth problem - worst Acropole 6/5/14 5:13 AM
Same thing on Fido. After they had release the update no more droped calls.
Re: Nexus 4 kitkat - bluetooth problem - worst Claire L. P. 6/5/14 10:22 AM

Hi everyone,


We appreciate your patience regarding this issue. As it turns out, a new update to the Android OS recently started rolling out; unfortunately, this release will not address this specific issue.


We realize that this issue is not going away, and please know that it is still on our radar. We hope that a future update will address it.


If you haven’t done so already, please read through this thread to determine if there are other workarounds or users’ suggestions that can help you out in the meantime.


Thank you again for your patience,

Claire & Paul

Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/5/14 11:19 AM
"We hope that a future update will address it."  OMG!  You HOPE a future update will address it?!  I am ashamed for Google and LG.  We have been waiting for over 6 months for a fix to this problem.  This is inexcusable.  I must ask myself if I can ever trust an Android update again.  This is disgusting and disgraceful.
Re: Nexus 4 kitkat - bluetooth problem - worst Ansgarr 6/5/14 11:37 AM
I've come to realize that Google & LG have abandoned support for the Nexus 4. There's no other excuse for leaving this kind of bug around for this long.
Re: Nexus 4 kitkat - bluetooth problem - worst Paul Younghusband 6/5/14 11:47 AM
Well blow me down, Google have really hit rock bottom now. I bought the Nexus 4 because it was a Google phone and would get the OTA updates first and with no Network providers branding which usually screws things up. Boy was I wrong, I feel I have been left out in the cold by Google, oh, and after updating to 4.4.2 I'm not getting the 4.4.3 update as some on here have :(

Seems like its time to jump ship and go the IOS route, at least Apple fix things pretty quickly. Anyone want to buy a Nexus 4 with the latest OS that doesn't work properly.
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 6/5/14 1:22 PM
4.4.3 same issue. WiFi on BT on using the phone while driving it disconnects and reconnects every few seconds. No longer crashes. Nexus 4.
Re: Nexus 4 kitkat - bluetooth problem - worst cricketsarah 6/5/14 2:01 PM
It's shocking that they think we can be fobbed off with such a flippant remark.  The problem is, it's only people who use bluetooth regularly that have major problems - my husband and daughter have a nexus 4 and 7 and because they don't use bluetooth they have no issues and think they are brilliant.  I, on the other hand, use bluetooth every day and have no end of problems.  Trying to remember to switch off wifi before I get in the car, switch wifi back on when out, is a nightmare - most of the time I forget and have incurred loads more data charges because I forget to do it.  It doesn't matter that there may be apps to help manage it - I SHOULDN'T HAVE TO DO IT!  I feel like most of you, we have been completely forgotten and they don't seem to give a hoot about the fact that most of us will go back to apple because of this.  

Well done Google, great customer service.
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/5/14 2:47 PM
I can honestly say that since I flashed my phone back to 4.3, I have had no Bluetooth problems, and I use Bluetooth almost every day.  I have, however, had occasional problems with phantom WiFi connections that can be fixed by going in and out of Airplane mode, and very occasionally, I get a black screen after a voice call that does require a power button hold down and restart.  Both of these incidences are very infrequent minor annoyances compared to the major Bluetooth problems with 4.4.2.  I guess my phone will be staying at 4.3 until I get my new Windows Phone or iPhone and sell the Nexus 4 on eBay.
Re: Nexus 4 kitkat - bluetooth problem - worst Mark Hogan 6/6/14 9:52 AM
Along with everyone else I am stunned that there is just "hope" for a fix in the future.

This is a fundamental safety feature. It is illegal in most countries to touch your phone when driving and this is the feature that allows you to comply with the law. Every time it drops brings the risk that the user will (by habit) reach for their phone to see what's wrong. Is this an upsell to the driverless car or maybe a hint that things will break and they only hope to fix them so you have to buy the latest car? This isn't the feature I would have put in the "hope to fix" list if I were trying to build user confidence in legal compliance & safety.

For over 50% of my contract with the network my phone will be missing a vital feature or I have to stay on 4.3. Does that also mean I then miss security updates such as heartbleed fixes as the phone is nagging me to update? Looking forward to upgrade time but I don't think Android will be top of my list!

Re: Nexus 4 kitkat - bluetooth problem - worst Youngmug 6/6/14 10:38 AM
I think Google's response most likely hints that this isn't so much a problem with Android as perhaps an interaction with the firmware from Qualcomm. I wish them luck on fixing that, if Qualcomm still supports that SoC.

Mark Hogan, I totally agree that it's a safety issue, and I hope that Google can figure out how to make a fix for those still experiencing issues. For Heartbleed, that shouldn't affect 4.3 for the N4 as Heartbeats are disabled (last I checked). You can download the Blueboox Heartbleed Scanner in the Play Store to check (and it scans for vulnerable apps too).

Sadly, I really can't add much more as my N4 took a tumble a week ago and the screen broke (I wouldn't mind if Google could get that fixed for me somehow). I can only hope that Google will provide a better indication of where the actual problem lies so everyone can at least understand why a fix is taking so long, and that they continue something like the Nexus program where a nice device can be offered at a really good price.
Re: Nexus 4 kitkat - bluetooth problem - worst Desverger 6/6/14 11:26 AM
I can't believe Google hasn't made this a top priority. Like some have stated, this is a safety issue. This tells me that Google doesn't take safety seriously. This is very interesting considering that Google has just recently been granted license to test their fully automated vehicles in the state of California. I think we should petition the state to reconsider this decision as it's clear Google doesn't care so much about safety. We as N4 owners need to add comments about Google's clear lack of interest in safety on all online articles that discuss Google's automated vehicles. Perhaps if they are publicly embarrassed Page or Brin will take notice and make this a priority. Very disappointing.
Re: Nexus 4 kitkat - bluetooth problem - worst Bruce Byrne 6/7/14 11:03 AM
So Claire and Paul are saying that Google's efforts for some of their most trusting consumers, those who chose the only pure Google experience Android phone, the Nexus 4, is "we hope we might have some time to pay attention to your little 70 mile-per-hour problem." Should they need more staff, some recently-former General Motors executives are now available. I'd be less snarky if they'd be more up front with  decision process that has deprecated this problem. Is the problem universal for all N4s?
Re: Nexus 4 kitkat - bluetooth problem - worst Nebojsa Zdravkovic 6/7/14 2:03 PM

I am using trigger app to switch off Wi-Fi while in the car. This brought
up another issue - after some time, wifi stops connecting to any ap and again I need to resort to reboot. This os and phone are a bad joke.
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 6/8/14 7:17 PM
Google wont fix this for a simple reason. the nexus 4 is at or about to hit that magical 18 months on the market.  As far as the big G is concerned the Nexus 4 is a dead device, hence the nice way of telling us to take a hike. :-( this was my first and last android device.  At least with Apple they support their devices for 3 years. 
 
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/8/14 10:27 PM
I don't think it's too much to ask that Google and LG at least 'leave' us with a properly functioning and patched device when it is 'up to date' with the last version it will get.

I expect this problem to be fixed before they declare end of support for the Nexus 4.

Re: Nexus 4 kitkat - bluetooth problem - worst tomsag 6/8/14 11:21 PM
Everything seems to be fixed. Just install Android 4.4.3 and forget the
Bluetooth problems.
Finally!

(have it installed for 3 days and all problems are not existent anymore)

Re: Nexus 4 kitkat - bluetooth problem - worst MIshaMsk 6/8/14 11:24 PM
This is embarrassing. Now I've finally lost all confidence in Google. It will cost me a lot of pain and money but I'm switching. -1 google fanboy. 
Re: Nexus 4 kitkat - bluetooth problem - worst cricketsarah 6/9/14 4:01 AM
I've now got the 4.4.3 upgrade - bluetooth appears to be working, but now the phone randomly switches off, and I no longer can use Sky go because it doesn't support the new upgrade.  What with Microsoft Exchange not working too, I have lost complete confidence in Google -  I would have bought the nexus 5, but I'm afraid it's back to the iphone for me.  Not that you care Google, but that's a whole families business you've just lost.

Re: Nexus 4 kitkat - bluetooth problem - worst Andrew Thong 6/9/14 1:13 PM
Workarounds aren't working on my end. Bluetooth and Wifi will crap out after a few days. I'd set up Tasker to reboot daily but it'll force close other apps and I'll need to root the phone as well.

I'm also beginning to think that the GPS is also affected. After BT/WiFi goes, I notice that the GPS start to become increasingly inaccurate till it eventually won't pinpoint my location. Noticed this on runs using Endomondo where it notifies me when it loses/recovers the GPS signal. As I continue my run the GPS goes dark longer before it simply never comes back. And these are runs that I've done plenty of times with no GPS issues whatsoever.

It's quite discouraging to see that there's no fix in sight- perhaps Google can give us a break on a trade-in and upgrade to a Nexus 5 (or its successor). That'd probably restore quite a bit of faith around here.
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 6/9/14 4:05 PM
In order for Google do do anything themagic words need to get dropped. Class Action Lawsuit. The issue makes the phone unsafe while operating a vehicle, does an accident need to happen or does a life need to be damaged and/or lost before the issue gets fixed?
Re: Nexus 4 kitkat - bluetooth problem - worst mattfiocchi 6/25/14 3:28 PM
Nexus 4. Since 4.3 update, I have not had the Bluetooth drop.  For me it was a Bluetooth headset that would often just cut out. Usually it would pick back up after a few seconds, but sometimes the bt would quit entirely and I'd have to reboot the phone. Anyway, for me setting the wifi frequency helped some, and disabling wifi was a hassle but did work.  The 4.3 update seems to have resolved things. Just got 4.4, and finally remembered to change wifi back to auto, so we shall see.
Re: Nexus 4 kitkat - bluetooth problem - worst Philippe LALANDE 6/26/14 2:17 AM
Same here. Nexus 4. Problem disappeared with 4.4.3.  Just got 4.4.4 installed. BT and Wifi work both well in alternance or simultaneously. Looks like the problem has been fixed for good.
Re: Nexus 4 kitkat - bluetooth problem - worst Jacob Park 6/26/14 12:11 PM
I can't connect to some devices I used to connect to (since the 4.4.2 update).  It seems to get worse with each update (4.4.4 can barely connect to anything now).
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 6/26/14 12:31 PM
Can somebody from Google weigh in on whether 4.4.4 addresses the Nexus 4 bluetooth problem introduced in 4.4.0-3?  Claire?

I am still running 4.3 until I get definitive confirmation the problem is fixed.
Re: Nexus 4 kitkat - bluetooth problem - worst Nauman Ahmad Nasir 7/4/14 10:20 AM
After the last software upgrade the Bluetooth disconnection is resolved. For the last three weeks I have very smooth connection with my mobile.
Re: Nexus 4 kitkat - bluetooth problem - worst Bruce Byrne 7/4/14 10:48 AM
I'm now on Android 4.4.4 on my Nexus 4, and so far I've not seen Bluetooth kicking out. But the behavior was always unpredictable. Clair, was this issue addressed or have I just been lucky?
Re: Nexus 4 kitkat - bluetooth problem - worst Bruce Byrne 7/4/14 10:48 AM
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 7/9/14 3:32 PM

Re: Nexus 4 kitkat - bluetooth problem - worst Zeldar 7/15/14 11:37 PM
I guess nobody at Google is watching this topic any more.  The 18 months is up and it's time for all of us to throw our misbehaving KitKat N4's in the drink and buy an N5, right?
Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 7/16/14 5:55 AM
the update never fixed my nexus 4, which just crapped out this week -- massively overheats, it fried 3 batteries. rip. shopping for an iPhone.
Re: Nexus 4 kitkat - bluetooth problem - worst Jacob Park 7/17/14 6:49 AM
Battery life is much shorter than it should be, me thinks...
Re: Nexus 4 kitkat - bluetooth problem - worst lgrider323 7/22/14 3:37 PM
I'm having the same issue.  My lg hbs 730 used to connect to my nexus 7 perfectly for a long time and now i can't even listen to music for more than a few minutes.  
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 7/23/14 9:19 AM
Google has obviously abandoned this thread, but I have to make one final comment.  If I ever consider buying another Android phone (which is not very likely), I must sadly say that I would only buy a Samsung-branded unlocked device.  Google's handling of this 'open, unlocked' phone has proven to be a total failure since KitKat.  Given the miserable handling of this serious issue, I would prefer to have a manufacturer vetting and fixing Android updates before they get loaded on my phone.  My Nexus 4 is on 4.3, which is the last update that worked satisfactorily. It has security flaws, but at least my Bluetooth works.
Re: Nexus 4 kitkat - bluetooth problem - worst Ed Guillen 7/23/14 9:56 AM
Again instead of complaing which is falling on deaf ears just drop the magical words. CLASS ACTION LAW SUIT.
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 7/23/14 11:01 AM
I am not an attorney.  If you are, then perhaps you can get one started?
Re: Nexus 4 kitkat - bluetooth problem - worst vylum 7/25/14 1:52 AM
Zeldar,

I don't think he is an attorney...

After someone yells two times to start a law suit to google, one might think he may be a representative of either MS or Apple. So a quick search (using google, not bing) and I found an Ed Guillen being a MS dev. (http://www.linkedin.com/pub/ed-guillen/b/8b0/9b8)
If it is the same person, at least he was righteousness enough to use his real name, which is a +1 from my side. I do wonder whether his first statement implying to own a nexus 4 is true though...

Still I share your frustration at google about this issue. Luckily I did seem not experience the problem anymore since the latest update, but still I find the service google showed here is inexcusable...

sincerely,

Willem Voogd
Re: Nexus 4 kitkat - bluetooth problem - worst Zeldar 7/25/14 5:28 AM
Willem,

I am encouraged by your post.  If what you are saying is that your Nexus 4 phone no longer has Bluetooth problems after loading the latest update, and assuming you DID have problems on 4.4.2, then perhaps I will try updating my phone to the latest ROM.  What version do you have on your phone?  Is it 4.4.4?  Also, did you have the problem where your Bluetooth would stop working and require a reboot to recover?

I was on 4.4.2 and re-flashed back to 4.3 after having terrible problems with Bluetooth.  I did not want to update again without definitive confirmation that the latest version fixes it.  It is a hassle to re-flash back to 4.3.  I don't care to do it again.

I wish Google would confirm or deny that the problem was addressed in 4.4.4 (or whatever version), but it seems Claire has disconnected from this thread and nobody else from Google is monitoring what customers are saying in this forum.

Thanks,

Norm
Re: Nexus 4 kitkat - bluetooth problem - worst Bruce Byrne 7/25/14 8:03 AM
Now running 4.4.4 on my Nexux 4, and Bluetooth connection to my car is at least improved, maybe fixed. My issue was that if WiFi was enabled,Bluetooth connection was irratically lost. Reestablishing connection required restarting phone, car and/or both. Since installing 4.4.4, connection has been reliable. Odd, how experience varies among us all.  Different hardware builds?  Combinations of interacting apps?  
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 7/25/14 2:21 PM
I never did try turning off the WiFi to prevent the Bluetooth problem.  I had already reflashed my phone back to 4.3 when that course of action was tested and recommended.  Sounds like you had the same problem when wifi was ebabled and it is fixed for you on 4.4.4.  Is your battery life OK?  I heard some rumblings about shortened battery life with 4.4.4.
Re: Nexus 4 kitkat - bluetooth problem - worst cricketsarah 7/25/14 3:58 PM
I think that the bluetooth issue was pretty much sorted with the 4.4.4 update, however battery life was still dreadful and it still didn't support Microsoft Exchange.  Was close to throwing in the bin, but then won a Sony Xperia Z2 in a raffle so happy days!  That runs 4.4.2 and has no problems whatsoever.  So bye bye Google, I won't be coming back!
Re: Nexus 4 kitkat - bluetooth problem - worst Bruce Byrne 7/25/14 4:00 PM
Battery life varies on tasks, of course, but for a middle aged phone, I can't complain. I'm a big fan of Agent https://play.google.com/store/apps/details?id=com.tryagent) which among a host of other things cools down power-hungry processes when the battery gets low.
Re: Nexus 4 kitkat - bluetooth problem - worst Acropole 7/25/14 9:19 PM
I tought it was fixed....but finaly still having the issue with the bluetooth even with kitkat 4.4.

I think the issue is coming from LG but as Google have made the decision to go with them, I think they should give a better support. Evety on I know who are with a samsung or any other Android seems to have no problems!!!
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 7/26/14 2:12 PM
Acropole,

Did you mean Android 4.4.4 or 4.4?

Thanks,

Re: Nexus 4 kitkat - bluetooth problem - worst Nebojsa Zdravkovic 8/8/14 12:37 AM
After update to 4.4.4, device now often goes into reset, on top of other pending issues. Way to go Google, you got me now seriously considering iPhone again. Not that you care anyway.
Re: Nexus 4 kitkat - bluetooth problem - worst Acropole 8/8/14 4:09 AM
I am done with Google and specially LG. Google you are not answering to any reply here and you seem to take us as granted. I am back to IPHONE and for long. I know apple is not perfect but no issue like this with no answers.

Good luck to other people with nexus (LG). I have a friend whos has a Samsung and he does not have problems but not usiing the bluetooth.

Other issues came out since 4.4.4. Reset oftenly, google maps very slow and have to remove all the updates to have it running clean and softly. Plus the bluetooth issue!!!! Enough for me

Thank you to people here for sharing
Re: Nexus 4 kitkat - bluetooth problem - worst Jamie NYC 8/8/14 6:54 AM
My Nexus 4 crapped out a few weeks ago -- it just overheats and fries the battery to the point of the red light of death. After replacing 3 batteries, it's officially retired. I REALLY REALLY wanted to wait for the larger iPhone, but fate would not cooperate. I just bought a used/like-new Nexus 5, and it's mostly great (although the camera still has shutter lag, and the phone crashes from intense video recording) but for $275 on eBay I'm just praying this thing will last a year or so. My Nexus 4, purchased brand new, lasted 20 months. R.I.P.
Re: Nexus 4 kitkat - bluetooth problem - worst therealzeldar 8/8/14 9:51 AM
Sounds like there are still problems with 4.4.4.  I think the best thing to do if you don't want to buy a new phone right away is to save all your photos and other objects and reflash back to 4.3 (which wipes the phone).  I do not have any real problems with 4.3.  No overheating, no bluetooth problems and I can generally get through the day without needing to charge the phone.  There are how-to's on the web that will walk you through the process.  Also, I must admit I really like the camera in this phone, particularly PhotoSphere, which makes replacing it a difficult process. However, after the abysmal performance Google support has shown us all here, my next phone will not be a Nexus.  iPhone or Samsung are most likely for my next device.
