This is an old post but I had the same issue and it turned out I had the camera/speaker/home button cable (this is the cable at the top of the phone) placed incorrectly. I didn’t think it would snap in but it did for me. Anyway once I turned it around it worked perfectly. When you snap it in make sure the cable going out of the connector towards the bottom of the phone.
