So i was playing angry birds and after about 20 minutes it started acting weird like my touch wasn't being recognized slightly. Eventually it actually froze and no touches were recognized. I ended up having to pull my battery.. nothing reflashed the rom, and even tried to reflash my old UD.. nothing.. my screen does not respond. everything else works, i can hold the power button down and move through the options with the D-pad, but no touch screen. anyone have any ideas what might be wrong?
