My mytouch4g keeps taking me back to the lock screen. It is happening repeatedly. I have also noticed that when the phone is locked, the screen keeps lighting up. Also, I am constantly asked if I want to power off my phone when I am using it. It has gotten very bad. I tried to hard reset and that didn't help. I don't know what else to do?!?!?!?! please help
I agree.. sounds like power button issues. Is the button still nice and springy or does it not move down much at all? A few of the production units had this issue. If its under warranty I would take advantage of that before its too late. If not... try a repair shop?
