Today I experienced a new first. The charge status is showing, but the USB debug and mount options are not showing up! Charging shows as "charging (USB)" and the taskbar and lock screen indicators show charging. It shuts down normally and the on-screen charge indicator shows up charging as it should. When I unplug it and plug it back in, it still properly shows the charge indicator as it should and doesn't turn the phone on.
The indicator seems to now be showing properly all the time and not reverting back to how it was when I unplug and plug it back in (at least for now). But the USB debug and mount options are never showing up.
