Hi, have you been facing this problem where your Samsung Galaxy Fingerprint not working again when you want to use it unlock your device? Don't worry this will fix it.
To fix the issue, I recommended you to go to setting, click on Apps and select show system apps using the doted menu.
Now select fingerprint and click on disable
After clicking on the disable, turn your device off and turn it on again, at this moment your fingerprint will start working again like before.
