iPhone 6s Apple Pay working intermittently.
iPhone 6s Apple Pay fails to work consistently after mild contact with water during rain.
iPhone housing has been replaced with aftermarket housing 3 months ago, but Wifi Bluetooth all works. Apple Pay worked reliably until contact with water.
So, is it a problem with the housing, pin connectors, cables or logic board itself? Is it possible that the NFC IC is broken? All other features of the iPhone works.
What is the best step to do now? Replace the housing, ribbon or NFC IC?
Is this a good question?
