The LG G2 battery doesn't come out so not like it got loose. I have tested it by sitting on the desk lightly and checking it later to STILL find it turned off. So I know I'm not bumping it. I have tried an app killer to kill apps before turning off the screen but it still seems to happen. The phone is still relatively new so I doubt it's hardware, I baby my phones.
Any ideas for ways to make it STAY on without flashing a new rom? Or maybe ideas for how to diagnose what is shutting it down?
(I am looking for ideas and useable feedback, please don't respond that my phone has hardware issues and needs to be replaced!)
