What do i do about this now, i had os 4.5 now 4.2 again and my phone is still radomly shutting off. to turn it back on i have to pull out and put back in the battery...........what do i do whats going on should i ask the ATT rep forum
it was alt+left shift+h it will bring up a help screen with all the info you need.
Why did you go from 4.5 to 4.2? What programs do you have installed on the device now? Any themes that might not be for your exact os/device?
I'd return the phone, if still under warranty. Then when I get the new one... Leave it be. No OS upgrades, I'd even be tempted to say do not install any 3rd party apps at all.
