my phone charging was stopped . i sent it to one of the technical shops to fix it . after he fixed it the tap to pay stopped working . is it related or not ? and how i can fix it . i think its something in hardware not software
The NFC antenna was likely disconnected or broken and just needs replacing. It is a super cheap part and is relatively easy to install. iFixit doesn’t sell them but you can find them on places like eBay for cheap.
