I took an iPhone SE generation three to Apple Store to replace battery and they broke the NFC functionality in a way that passed their simple diagnostic tool but failed to work in the real world. I had to go back and reset the phone and upgrade my IOS so they could troubleshoot it (the phone menu for setting appointments does not allow you to pick repair broke NFC funny enough) and they were nice enough to give me a new iPhone SE to replace we proved it was broken. But that was kind of worrisome and put me off any kind of Apple self repair for something they still make.
