iPhone 4 Screen is unresponsive after replacement
I recently replaced my touchscreen on my iPhone 4 following the guide on here since it was dropped and the glass was cracked. After it's been replaced the LCD works but the touch sensor doesn't work. Is there any reason for this to happen?
When I tried putting back the old screen the screen worked sporadically. I was only able to swipe the lock screen a few times however this was not the case before i opened it. I had a problem with a screw missing but i dont think that should be the problem. I even reassembled at least 3-4 times to make sure the ribbon cables were all intact. This is an iPhone 4 Verizon version.
