Today I dropped my phone from about chest level. And when I picked it up the screen wouldn't turn back on. There are no any cracks on the screen and all of the touch stuff still works, what i mean is when the phone is on i can still unlock and scroll down i can feel it vibrate when I do so. I have tried pulling the battery and restarting and nothing will help. Does anyone else have any idea of whats wrong or how to fix it.?
