Ok, so, I was using my phone when the screen froze up. I turned the screen off then turned it back on. It didn't go to the passcode screen, but it went to the page I was a t before, but the screen was all dark and stuff and I couldn't do anything. It has doone this a couple times before and I took the battery out and put it back in and it worked fine. That didn't happen this time.I tried to turn it on but it won't turn on. Yes, I've charged it, taken battery out a few times, and waited hours. Nothing seems to work. I've done the power and volume pressing thing too. Please please please help!! :''(
