How To Fix Touch ID Failed Error On iPhone

This is another issue with some of the Touch ID enabled iPhones!

The Touch ID failed error message has already started haunting many iPhone 5s and iPhone 6 users. The feature works great for some time, and then suddenly stops functioning properly without prior notification.

And when you try to setup a new Touch ID fingerprint, it displays the error message that you don’t want to see on your iPhone. It’s also an annoying process to start over again, as it doesn’t even let you complete the fingerprint registration with your own fingerprints.

So, how do you tackle this problem? Is there any possible fix to it? Let’s find out now.

Note – For those who’re facing different Touch ID problems, you may go through this post that revolves around possible causes and fixes.

Touch ID Failed Error

In case you’re wondering about the error message, here’s how it appears on some iPhone devices –

This basically means that the technology or device is not accepting your fingerprint registration on iOS platform.

When you see this type of message on your screen, it becomes confusing and frustrating, especially for those users who’re not so used to handling such errors on smartphones.

Well, there are a few things that you can try to resolve this issue. We’ll discuss them below.

1. Update iOS Software

That’s the first thing you should do when you come across any software issues on iOS devices. It’s better to keep your iPhone updated with latest software version.

For this particular case, many users had reported Touch ID failed error with iOS 8 update. However, new releases have apparently fixed it for some of those users.

If you haven’t downloaded it yet, Apple has already released lots of major software updates now. Just go to the ‘Settings’ app and download it for your device.

2. Touch ID Error Fix

It’s not an official fix to this problem, but it does seem to have worked on lots of iPhone devices. So, there is no harm in trying out for your phone.

Please take a look at the steps below and follow them as suggested.

1. Open the ‘Settings’ app on your iPhone and select ‘Touch ID and Passcode’ from available options.

2. Enter your Passcode if any.

3. Disable the ‘iPhone Unlock’ and ‘iTunes & App Store’ options.

4. Restart your iPhone by pressing Home and Power buttons simultaneously.

5. Now, open the ‘Settings’ app again and head over to ‘Touch ID and Passcode’ option.

6. Enable the ‘iPhone Unlock’ and ‘iTunes & App Store’ options.

7. Enter your iTunes Store password when asked.

8. Once you’re done with these steps, you can start adding your new fingerprints as explained below.

3. Setup Touch ID Properly

If you somehow manage to get through the fingerprint process, please do it correctly.

Here’s how to setup your Touch ID on iPhone –

Steps to follow:

1. Open the ‘Touch ID and Passcode’ menu from ‘Settings’ app.

2. Tap on the ‘Add a Fingerprint…’ option.

3. Place your clean finger on the Home Button as requested by Touch ID feature.

4. Place and Lift the finger as per screen instructions so that it can detect and register your fingerprint correctly.

If you don’t do it properly, you’ll get the following error message. Just select OK and continue with the same process.

5. Then, you will be asked to adjust your finger for grip detection.

In this step, you should try to cover all the edges of your finger that do require while using the fingerprint feature. You should also exert a bit of pressure on this button, which helps in recognizing your finger grip.

6. Enter the iTunes Store password if any. This will help you make App Store purchases with fingerprint technology.

7. Close the ‘Settings’ app and restart your iPhone. Try to unlock it using the same registered finger.

Done. Now, that’s how you should setup your Touch ID on iPhone!

Multiple Fingerprints Setup

This is an important step for your Touch ID feature.

Don’t just rely on one fingerprint to access your iPhone! It will make things more difficult later if you can’t unlock the device using Touch ID.

Apple has provided multiple fingerprints setup under Touch ID and Passcode option. So, do use it and add more fingerprints according to your preference.

Multiple fingerprints also allow the sensor technology to understand your finger pressure, grip & touch. Ultimately, this information is used to improve and process previously collected data.

Coming back to the Touch ID failed error, it could also arise due to several other reasons that may not be associated with iOS software. I’ll list some of these reasons below.

  • Water/Coffee spilled on the phone.
  • Your phone was exposed to moisture for a long time.
  • Your phone was exposed to excess heat/fire or any other extreme conditions.
  • Home Button is not functional or damaged.
  • Battery/Screen/Camera Replacement
  • Logic board/Flex cables damaged.

If you’ve experienced these issues before, your phone needs immediate attention from Apple’s support team. Please find an Apple Store near your place and let them examine your faulty device.

So, that’s pretty much about the Touch Failed issue. In case you’ve figured out any other solution, do let me know in the comments.
