Acrd, Feb 23, 2018 : Yesterday I tried unlocking my phone normally (fingerprint scanner) though it didn't work. I have multiple fingers scanned so I tried on them too, still didn't work.. my fingers didn't get recognized. Rebooted the phone and entered my pin , locked the phone and it worked again normally. Thought that was it , its a one-time glitch and it would not happen again but about 15 Min ago the same thing happend. Rebooting the phone fixed the issue. Is this a bug? It's very annoying. Only had the phone since the 12th of Jan.
