Display and touch doesn't work
Hi, i have a problem with my iphone 4 gsm. after a fall the screen went black and it broke. I replaced the display (I've tried 3-4 of them) but the problem is that you see a central oval clearer and the rest black with some lines and halos but no system image. There is something that probably should not be. help me please. thank you
