This is probably the THIRD iPhone 8 or 8+ that has had this issue. Even though we were careful to remove the camera flex cable and the tape with it, and transfer it to the new LCD/Digitizer assembly, the earpiece REFUSES to work. The camera works just fine. I need assistance and answers. I have cleaned the contacts with alcohol. I have installed Kapton tape. I have switched out the piece with a new flex cable and new ear piece speaker. Yet, I know it worked BEFORE we took the phone apart. Suggestions on how to use the ORIGINAL flex cable?
