Touch ID has suddenly stopped working on your iPhone 6/6 Plus and you are looking for some quick solutions to make it work again? You might also be willing to find out why the fingerprint identity sensor has refused to function as usual. If you are on my expected line, then go through these solutions to cut the chase right away.

Coming back to the question as to why Touch ID may not be working on your iPhone, I would say you might have to blame sweat, liquid or even improper placement of finger. Though I won't rule out software glitch as well.

Touch ID Not Working on iPhone

When iPhone 6(s)/6(s) Plus Touch ID Not Working…

Before we provide you any solution to your Touch ID problem, just imagine what makes your Touch ID fail or when Touch ID fails to work.

Calibrating Fingerprint Properly

One of the first mistakes happens when you calibrate the fingerprint. Even though the iPhone 6 or 6 Plus sends you a message that your finger has been calibrated successfully, there are some chances that the calibration is not done perfectly.

When you calibrate, hold your iPhone as you’d normally hold. Don’t hold it “perfectly” because that’s not how you hold it during normal use. Then, calibrate the finger.

While calibrating, please ensure that you put your fingers in all possible positions including edges & tips of your fingers; all parts of your finger should be scanned. Also, ensure that your finger touches the metal ring around the Home button. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring. If it does, remove the case or screen protector and try again.

This will help you later when you use your fingerprint to unlock your iPhone 6 or 6 Plus.

No Damp Screens or Fingers

In other cases, dampness, moisture, sweat, cold – all of this plays a role in preventing the TouchID from working correctly. This happens both ways: if your finger is damp or if the home button has some moisture over it.

Touch Lightly

Apply less force when touching the Home button of your device.

Keep Your Finger Dry

Make sure to keep your fingers clean and dry.

Clean Home Button

Use a smooth cloth to clean the Home button and your finger and try again.

Do not Cover Home Button

Ensure that screen protector or case doesn't cover up the Home button of your device.

Register Finger Properly

Your finger must be properly touching the capacitive metal ring and the Home button. Make sure to keep your finger at one place at the time of authentication.

  • feroz

    i did all steps no use after update ios 9.1

  • Thank you, resetting the iPhone helped with the fingerprint problem as well as the stuck front camera problem, thanks !

  • EdFromTheTop

    I meant 6 plus. So sorry.

  • EdFromTheTop

    I need clarification, please. I changed a cracked screen on an iPhone 6 on which everything was previously working fine. After the change the home button no longer functions. I understand that is a separate issue from my main question which is as follows. I have read that if one replaces the shield ad attached home button cable, the fingerprint ID will no longer function because the original home button is uniqueto the logic board. Is there no way to restore fingerprint ID after having to change the home button, which I will apparently have to do as the original is no longer working? Any insight will be greatly appreciated. Thank you.

      I have the same problem. What have you done?

    • sania sharfunnisa

      I am facing the same problem. Please let me know the details

        I had to replace my cracked screen too. By doing that, I damaged the flexcable that connects the Home-Button with the LCD Shield Backplate. So I ordered a new LCD Backplate, mounted it and everything worked fine. If you did not damage the Home Button or the connector on the Home Buttons side but the Backplate, you can order one, its cheap. But beware: My Home Button and Touch ID worked perfect for 2 month, now suddenly the Touch ID only works about 1 time of 10. And it becomes worse, I have no clue what could be the reason.

      • Sperr Gebiet

        I just reopened my iPhone and ‘rechecked’ the connection between Home Button and Backshieldplate (just by pressing gentle on it, not by de- and reconnecting it). Luckily it did the job, probably it was just some contact not working properly. I hope that will last longer than 2 month now.
