[Android Central Question]

I have did everything I can think of to stop it. but nothing seems to be working..

Impending hardware failure? Back up your personal data while you still can, in case it is that.

It sounds like either a loose connection or the screen is about to go bad. As belodion said, back everything up now while you still can.
