Today i dropped my s3 (indoors), the back cover came off and the battery fell out. I put the battery back in and tried to turn it on, i heard it turning on and the blue LED light came on but nothing showed up on the screen. it turned on and i tried unlocking it and i could feel it vibrating but no picture. i can hear it when i get messages and the light comes on and when it rings, the phone vibrates and i can answer. everything works but i just get a black screen. the screen was already smashed and you can see underneath the screen in some places. Thanks, Harvey. PS: PLEASE HELP ME IT'S URGENT!!!
