My S7 has stopped accepting fingerprint. This happens to all of us at some point the phone won't unlock for whatever reason, the message comes up saying try again in 30 secs then it works. This is not the case I've kept trying and each time the waiting time increases and the phone won't unlock. I'm currently waiting for 60 mins to be up so I can try again. I tried turning the phone off and on again I used my pattern when the phone had restarted by the wait time was still there. Anyone have any ideas on how to get the phone to unlock once the time is up. I have both my thumbprints on it but so far they hasn't worked.
