Hi there and welcome
When you restart you always need to first input your security code, that you set up when you setup the fingerprint.
Once you do it the first time after a restart, then you can go back to using your fingerprint again.
What happens when you enter in the password?
The password ***** ***** from Samsung, its the password ***** entered directly on the phone when you set up the fingerprint scan.
Do you recall what this was?
The only other work around is a full reset of the phone, as the reason for this lock is to protect the data.
If you do not recall the password ***** you need to reset the phone.
This will remove all data from the phone and return it to new, but there is no way to avoid this.
To do the reset, please do the following.
The phone is then returned to new , wiping all data not backed up online, so you can then set up the phone again.
But you will need to do this if you cannot remember the password ***** unlock it.
If there was a way to get around the security, it would be known very quickly and resolved. They had a work around with the S2, which was patched within a few days, now they have made it that no one can get around it due to the way the encryption is implemented.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
