A few weeks ago, I installed the Card emulator app, to read a nfc tag of mine. After playing a bit with the app, I uninstalled it. Right after that, I went into nfc settings to check everything was ok (the app was enabling/disabling nfc on it's own, without my interaction).

And it's not ok ! If I toggle on nfc, the switch seems to be enabled but greyed out, and becomes disabled after a few seconds (it then stays greyed out, so I cannot interact with it). The "default payment app" was set to "card emulator" when the app was installed, and greyed out. With the app disabled, this settings is now set to "not installed", but still greyed out... nfc settings

My phone is a Huawei P9 Lite (VNS-L31) running Android 7.0 Nougat (Stock ROM) rooted with Magisk 17.1 and TWRP 3.1.1-1.

I found the app's log : logs

Last lines of each section are interesting : service call nfc 6,7 or 8 didn't work, it seems the app couldn't restart NFC or something like that... I also have all the app configuration files if needed.

Have you got any ideas to make the nfc functionality working again ?
