    Since the inception of the fingerprint scanner, I have never had a phone work correctly with the fingerprint scanner. I now have a 6+ and once again the fingerprint scanner works for a few times then it stops functioning completely and I go back to keying in the passcode. Am I the only one that’s experiencing this. Is there a fix? I would love to hear your thoughts………!
    Thanks…….!

      You are not the only one actually i am using iPhone 5S for over a year now (have 2 pieces) .. its a sensor which doesnt respond quickly as it should do. Then its your fingerprint if you install your thumb impression twice or thrice it will help the sensor to recognize immediately (though it works for me) and sometimes it becomes totally unresponsive that iPhone asks for a passcode to unlock the phone. Right?

        The easiest way around this is to enter one of you fingerprint multiple times. for example, my Right Thumb Print is enter 4 times as different fingerprint entry. Now I never had any problems using the fingerprint Scanner. like so, Right Thumb Print is Fingerprint 1, Fingerprint 2, Fingerprint 3 and Fingerprint 4 all are my right Thumb Print. hope this helps…
