Chosen Solution
I replaced my iPhone SE into a clear plastic custom housing shell that i bought online. For picture reference on what i’m even talking about, here is a photo. Everything on the phone functions perfectly, except for the NFC antenna. I didn’t notice this for many months because i rarely ever use apple pay. But i just decided to today and failed to get it working. Everything else on the flex cable works perfectly (volume rockers, mute switch, flash, power button, & vibrator), but nfc doesn’t seem to function at all. Does having a plastic shell inhibit the ability to use NFC? Did i not move a certain part over? Any ideas on how to trouble shoot?
I replaced the housing on my iPhone SE and ran into the same problem — Apple Pay didn’t work. After a lot of troubleshooting, I realized that the NFC antenna contact was misaligned. This is an old post. I’m posting my solution to spare the next person who runs into this from the headache. The offending contact is here:
The circled screw secures the NFC antenna (built into the power button flex cable) to the motherboard. Note the small, metal, inverted “J” coming out of the left side of the screw. That exposed piece of metal, pictured here:
Needs to make contact with the motherboard pad pictured here:
(Ignore the highlights around the two chips. We’re looking at the line on the top left of this photo.) It’s very easy to either place the motherboard on top of the ribbon or to screw the surfaces together sideways, resulting in poor contact between the two components. Good luck!
The NFC antenna is connected to the Power Button Flex. [Dead link removed] You may have either damaged the flex, connected it improperly or there is an issue with your replacement housing. Generally speaking, the housing is part of the antenna. If all your other antenna’s work, then it may just be one of the first to options above.
elahd Thanks dude. (I use online translator) Your instuction helped me. The reason for the breakdown was different. Under the NFC connector, near the battery, a sealing parallon has fallen. And modern NFC contact block stopped working. I cleaned the contact under the bolt (unscrewed from the board, back to the thread retainer) and restored the contact on the connector. NFC is working again.
Other instructions on the Internet did not correspond to reality. Good luck.
