Step #8. Now add Fingerprint.

Before you go for the new Fingerprint addition, take care of the following:

  • First off, ensure that your finger/s is/are clean and dry.
  • Put your finger properly so that the Home Button is covered entirely.
  • Never tap quickly.
  • Never press down hard.
  • Control your finger’s movement while Touch ID is scanning.
  • Ensure that your finger touches the metal ring around the Home button.
  • Ensure that mobile case/cover and/or screen guard doesn’t cover the Home button or the ring.
  • If the Home button smudged with lotions, sweat, moisture, oil OR if your finger is cut or dry, you may not be able to add your fingerprint.
  • If you add more than one fingerprints, Touch ID may take a little more time to identify your finger.
  • Touch ID will not work for purchases in case Require Password is set Immediately. (Settings → Touch ID & Passcode → Require Passcode)
  • Always clean the Home button with a lint-free cloth.
  • Finally, launch Settings app, go to Touch ID & Passcode and check that your iPhone Unlock and iTunes & App Store are toggled ON.

If the issue persists, you can for “Reset All Settings”. Go to Settings → General → Reset → Reset All Settings.

  1. 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………!

    • 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…
