So my little guy accidently dropped my phone today. The back cover fell off when it landed. I put it back on right away and even took out the battery and put back in, but now the screen is predominantly black with little green specs or lines and then with some color at the bottom. Does anyone have any suggestions on how I can fix this, or if it can be fixed if I take it to a Verizon store. I just don't have the money to buy a new one. Please help!
