I cracked my iphone screen and had it replaced by a professional. The earpiece was really low so I opened it up to try to fix it myself. I took off the cables #1, #2, and #3. I couldn't fix the earpiece so put it back together, and had a tough time replacing the digitizer #3 cable...I bent it a little. Now when I am on a call the screen will not lock and I always press mute with my face. Did I do this or did the digitizer break when the screen broke? I need to know if this was my fault or the guy that fixed it initially didn't actually fix it.
