I always re-register my finger print due to permanent burns on my fingers which causes issues. Don't ask it's too personal but the finger print scanner stops working entirely at 47%
Thank you for sharing this! Please also send an error report through Samsung Members app so that the developers can take a look at what may be the cause
I did have the same problem, it took me many attempts to register the thumb print, and I try to add the same print in each of the four slots. Gave up trying a few times.
