Why iPhone screen has lines and dead pixels after screen replacement?
Hi, I have an iPhone 4S that was recently dropped and the screen got cracked. Everything was working, just the digitizer was cracked.. I got a new display and after the reassembly the screen had various lines, which were flickering, but the phone itself was working, I could get calls, talk with Siri, use camera, but I couldn't see anything because of the background and by the way there were like some pixels that were out. After I figured out I can't see threw the screen, I putted back the first, cracked screen into and everything was working. Can you tell me is it the new screen problem or is it something else that I could have done with the new screen?
Thanks in advance.
Here is the picture of what I get: https://www.dropbox.com/s/ki4fap367038gy...
