Hi guys. I have a really strange problem. Today my phone dropped from my desk with the screen faced down. I picked the phone and i saw the screen went black. After a while some lines appeared and then after i removed the battery and reinserted it the screen was back to normal. The only problem now is that each time i unlock my phone there is a delay (black screen) and a kind of flickering and then the phone is ok. If i lock and unlock it constantly it stops doing this. If i let it for one minute and try to unlock it the same happens. Do you have any idea what's wrong ? I have never faced something like this. Usually when the screen brakes is has constant lines or constant flickering. Not only when unlocking the phone. Please share your ideas.
