4 NFC and apple pay problems
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
Это хороший вопрос?

After reconnecting all 3 of the connectors shown in the screenshot the NFC function worked. I still don't know which one of these was the problem but it seems that the connection was not passing the signal through. For anyone wondering how to test NFC I use NFC tags which I write to using a compatible phone and then just tap the top of the phones to see if the tag gets picked up.
