Hi my nexus has been working great until a couple days ago when it has decided to not go into deep sleep because the screen continously goes on and off because it thinks it is being plugged in to charge. This is absolutely killing my battery and I don't know what has changed with the phone for it to start this. I was originally on AOKP M4 when it started and wiped everything to see if something went wrong but it kept going. Since then I've tried different roms and different kernels but it wont stop. I've had my phone since launch day and didn't get insurance so any suggestions?
