Troubleshooting the Fingerprint scanner
My Xperia X fingerprint scanner stopped working and I'd like to trouble shoot it to figure out if it's a hardware or software issue.
I read all about the 5-print limitation here, to the best of my knowledge I did not surpass that limit before the scanner stopped working, I did attempt to enroll a finger after that which for sure was beyond 5 fingers.
As far as I can tell from systemctl the daemon seems to be working and journalctl does not show any errors.
So:
Can you please give a trouble-shooting procedure?
Is it possible to reset what fingers are enrolled?
Thanks

Update:
I used the below procedure to reset the fingerprints enrolled, I enrolled 4 fingers after which everything was working fine for a day.
Today the fingerprint sensor again stopped working
systemctl status sailfish-fpd
showed that the service had crashed, a restart did not help.
After device reboot the configuration interface listed no enrolled fingers and I was able to enroll 1 finger after which the 5+ behavior happened (unable to enroll another finger). The re-enrolled finger works while the previously enrolled fingers do not, sadly reboot means that the previous logs seem to not have been preserved as far as I can tell but next time this happens I will first get logs of the failed service.

Update 2:
Well that didn't survive long (less then 5 hours), daemon crashed after manual restart no enrolled fingers are shown.
Here are some logs:

Incidentally CSD runs its' check against the sailfish-fpd daemon so I'm not sure to what extent it can truly check for a hardware issue.
