Could you send more data provided by the app NFC Logger (available on Storeman)?

After reboot, these messages have disappeared and NFC works again.

Same here with XA2 4.4.0.72, but unfortunately it doesn’t wirk better after reboot.
NFClogger return same message in top of topic…

Thanks for the original report @phklrz, and @mkz for sharing your experience. It’s unfortunate that the reboot didn’t address the problem for you. Given this, I’ve created an internal report about it and tagged it here as “tracked”.

Same here with XA2 DS running 4.5.0.21 and 4.5.0.24. Device won’t read NFC tags even after a fresh reboot.

Perhaps this topic should no longer be marked Solved?

## Log truncated:
## The previous four lines keep repeating every 650 ms or so.
## Nothing else is logged until I toggle NFC off from the top menu.
