All of the scanned fingerprints are gone and when I try to scan new, I go through the scanning procedure but at the and I receive Error message and option to cancel or retry. The fingerprint sensor test has passed succesfully.

Sailfish version? Tried to update system reboot etc? Have you done something that could've caused this? I would suggest that you try to give as specific information as you can :)

SFOS 2.2.0.29. I tried reboot. I.have the.latest update. I noticed that fingerprint stopped while normal dayly use. I.checked with CSD and tried to add finger.print several times. It looks like the sensor is OK but the wizard cannot add and activate the feature.

I have seen this in Android. Solution is to delete the fingerprint database and reboot (I guess restarting aliendalvik could work). While not having tested this on SFOS, its very likely the same issue. Try this: Locate /data/system/user/0/fpdata/ and delete the file user.db

The fingetprint has never worked in alien dalvik for me. If this was trouble with my device please provide some help to fix it. It will be great if I can use the fingerprint in android apps.

Hi @shults, how many saved fingerprints were there before you tried to add a new one?
