Fingerprint scanner does not work

[Alya08]

Help, please, solve the problem with the work of a fingerprint. When I try to register a new fingerprint, I get the error "Failed to register a fingerprint. Delete unnecessary data from the internal drive and try again", but the memory of my smartphone is clean.

Try as follows

Goto settings-apps & notifications-app info- tap 3 doors upper right corner-tap show system-find fingerprint-tap on it-tap on storage

Then clear cache and data.

Restart device

Set up your fingerprint scanner

O, a clean fingerprint scanner works better too.

 PS report back if this worked for you.
