I use an NFC-app (HID Mobile access) to open locked doors at my work. It has worked great for several years, and then it just stopped working a couple of weeks ago. My colleagues who don’t have fairphones don’t have the same problem. I followed all the steps at the Fairphone NFC troubleshooter page without luck. Does anyone here have any tips? Wouldn’t want to buy a new phone just because of the NFC.
