Why won't anything show up on my screen
About a week and a half ago my friend hit my phone out of my hand and it dropped on the ground. When I picked it up it hadn't cracked or anything and it looked fine but when I pushed the home button green lines appeared on it and it just went black. It wasn't responding to anything until I tried charging it then it made all of the noises that a phone should make, but the screen won't turn on. Please help.
