Weird NFC issue *Complex?*
I would really appreciate if anyone can help me out as this issue seems bizarre to me and something I have never encountered.
NFC only works on iPhone 13 when the display is lifted from housing. Once the top portion of the display is clipped in, NFC no longer functions! Like the display is a barrier to the signal?
History: the phone has had a housing replacement which includes wireless charging flex. I have tried swapping genuine NFC flex (near camera) same issue. Not a motherboard issue as installed it into complete phone and works fine. To me this seems like a housing issue? Can a housing be faulty? And other things it can be? I have scratches the metal connections where the flex is attached to the housing for better conductivity. Still nothing.
The original housing has spot welded metal extensions which touch with the metal part on the NFC flex, on the replacement this isn't present.
