Hi, @mick51. That's very strange indeed. Are you able to share a photo showing the error message that you are encountering when trying to input your fingerprint?
Additionally, please can you let me know whether you have reached out to any of our Support Teams to help ensure that you regain access to all of the features and functions of your phone again?:
That's certainly an anomaly @mick51 🤔
Will your phone allow a Factory Reset as a last resort or perhaps seek to use a Samsung Service Centre.
I wish you all the best with this

The advice I offer is my own and does not represent Samsung’s position.
