My samsung A51 is asking finger print sensor calibration needed. What to do?

Please remove all fingerprints, wipe the cache partition, and then register again. Subsequently, conduct a thorough inspection.

I am trying to register my fingerprint for the first time and it was saying fingerprint sensor need calibration.

Please ensure your data is backed up, then perform a factory reset on your device. Subsequently, re-register your fingerprint. This should resolve the issue.

Factory reset on new device? Are you sure?
