I've had my phone for months now. About a month ago i dropped it, but nothing seemed wrong till now. The minute the screen locks it just freezes and stay black, when I swipe it I can hear it unlock so i'm guessing it's kind of working but just stays black. After a million clicks on the lock/unlock button it eventually gives up and TA-DA the screen appears (or when i switch it off and back on). I'm out of town right now for another month so can't really go to the company, so can I do anything about it?
