I have the same problem here. It's the second time I replaced my iphone 5 screen, and last time it worked perfectly fine. But this time, I broke the copper receivers, the two parts literally just became two separate parts, so I ordered a new flexible cable with camera, and put it in, and tried to loose the screw, but still no luck. Tried to align the receivers and the two golden connectors on the square piece, but no luck again.
It's so annoying that you can't hear anything from it when making calls. Anyone can help with it?
many thanks.
