Just a quick question. Recently repaired the back glass of 11 however damaged the wireless charging coil. Ordered a new one and installed. Now Apple pay is not working so NFC is not working either. I just wanted to know if the coil is the NFC problem? Or is it the flex cable at the top of the phone that’s the problem? Thanks Update (11/17/2020) Any idea which one it is? There are 3 connectors coming from 3 different antennas at the top. I have highlighted them
It’s at the top of the phone, usually around the camera.
The NFC antenna is frequently mislabeled as Bluetooth on vendor sites. It is generally mounted between the camera module and the housing. It’s difficult to find pictures of it in place due its positioning in the housing, but it’s this one mounted into the side of the chassis here. It is the one with the screw on the inside of the camera cutout. In nearly all iPhones it will use the standoff which goes into the board near the camera as a grounding point.
