Cleaned screen, everything works except the proximity sensor.
So I had some dust under my iPhone's screen and after some problems with the home button refusing to work, I've got it all working again. I just realized that when making a call, the screen will not turn off which leads me to believe that the Cable #3 isn't in correctly. I'm curious though, how is this possible when I'm able to call people and hear them? Doesn't Cable 3 handle all that? Any ideas for a fix?
