Edit: I panicked, went to open a support ticket for FP4, and read that maybe Safe Mode could fix the problem. I rebooted into SM, the sensor was working ok, rebooted in normal mode again, and it’s working again. I have no idea what might have happened.
Today I rebooted my Fairphone 4 and this materialized a software update that somehow was pending (I was not aware of it, nor do I remember when was the last time I had turned it off). As a result, the fingerprint sensor has stopped working: my finger is still saved in the phone, but the sensor will just not reach. This means that I can’t access some critical banking features.
The phone has been working perfectly fine for half a year, until today.
How can I debug or troubleshoot this issue myself?
Hi astrojuanlu and welcome to the community forum.
Don’t worry, the best questions are those that come with their own answers
Glad it’s working again!
Thanks for sharing this unpleasant experience.
Glad that it works again.
TL; DR : restart your phone once more after migrating to Android 12 !
Exact same issue here : after installing this exact same system update, I was surprised to notice that my fingerprint sensor is not working anymore
It wouldn’t unlock the phone, or even vibrate when I press my finger …
A single “regular” restart of the phone and now it works again !
A bit frightening, but really not that serious in the end
