As of about a week ago, my phone has started acting up and freezing on me. I never really had this problem before and just blew it off, took the battery out and restarted it. I have always had problems with the phone rebooting itself. Ever since the first day I had the phone. Yesterday was the worst, the phone would go in my pocket, sit for a little while, and then when I pulled it out and tried to unlock it via the button, I would only get a black screen and no response from any of the touch buttons on the bottom. I could tell the screen was on because there was a sight amount of light coming off the screen, but I would have to pull the battery out to try it again. It seems like the frozen apps are causing the black screen problem, but I don't know what is causing the auto reboots. Any help would be appreciated. I have also read that dead pixels on the screen could be the mark of a bad phone. I have one. What should I do???
