Fingerprints lost after updating or restarting the phone

Vijay Chauhan

If your fingerprints are lost after updating and while registering again ,it says that the fingerprints are already registered .   Want to troubleshoot this.   Just go on pattern lock and change that to swipe or none .  After this , again set the same or different pattern whatever you want.  And finally go to fingerprint lock and add the fingerprints.     That much simple .  Isn't it.
