How To Fix Touch ID Failed Error On iPhone

The Touch ID Failed error has now started haunting many new iPhone users.

The feature works great on these mobile phones for some time, and then suddenly stops functioning without any notification.

And when you try to setup a new Touch ID fingerprint, it displays the unfortunate error message on the iPhone’s screen. It’s also an annoying process to start over again each time, as it doesn’t even let you complete the fingerprint registration with your 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 the possible causes and fixes.

The Touch ID Failed Error

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

This error essentially 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 looks confusing and frustrating, especially for those who’re not so used to handling such errors on smartphones.

Well, there are a few things that you can try to fix the Touch ID failed error. We’ll discuss them below.

1. Update the iOS Software

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

Many users have noticed the Touch ID Failed error after updating their devices to iOS 8 update. However, the new software updates have apparently fixed the issue for some of those users.

If you haven’t downloaded the latest update yet, Apple has already released lots of updates in recent time. Just go to the ‘Settings’ app and download it on your device.

2. The 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 the Home and Power buttons simultaneously.

5. Now, open the ‘Settings’ app again and head over to the ‘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’ve completed these steps, you can start adding the fingerprints details as explained below.

3. Setup Touch ID Properly

It’s important to setup the Touch ID details correctly on iPhone devices. Here’s how to do it –

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 your finger as per the screen instructions. This action will help iPhone 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 the grip detection.

In this step, you should try to cover all the edges of your finger. 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 step will help you make App Store purchases using 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 the Touch ID on iPhone!

Multiple Fingerprints Setup

This one is an important step for the 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 choice.

Your fingerprints also allow the sensor technology to recognize the finger pressure, grip & touch. Ultimately, this information helps improve and process the previously collected data.

Coming back to the Touch ID error, you might come across several other reasons that may prompt this error. It doesn’t have to be related to the iOS software on your iPhone.

Here’s a list of some possible reasons –

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

If you’ve experienced these issues earlier, your phone needs an 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 us know in the comments.
