I got the phone when it came out and haven't had an issue or complaint yet. But today my fingerprint scanner decides not to work. I reset the phone because that usually does the trick, but not this time. I yanked the battery, tried to reprogram my fingerprints and nothing. It's not even recognizing that I'm swiping either finger; ie I'm not getting the swiping too fast error or what not. Any suggestions or is my scanner kaput?
