I've had problems with my battery, but nothing else. Figured out that I just needed to change the charger. So I've had no problems for about a month. Tonight, while using my phone it would just randomly turn off, and then the lock button wasn't working. The only "reaction" I would get is my phone asking me if I wanted to turn it off. Later (about four hours of turning it back on every ten minutes) I was sending a text and my phone went glitchy and turned off. I tried turning it on, no sign. Took the battery out and put it back in a few times. Still nothing. Plugged it in to charge and it started charging, finally the power button let me turn it on. But again, the phone keeps shutting off, and the battery isn't low.
