Tackled in this post is a problem with Touch ID that suddenly stops working after installing the latest update to iOS 11, the iOS version 11.4.1. Read on to find out what options to try on should you too ended up facing the same post-update dilemma on the same device.

How To Fix iPhone 7 Touch ID Not Working After Installing iOS Version 11.4.1

First solution: Check and ensure that Touch ID is enabled on your iPhone 7

Your iPhone settings might have been automatically altered or overridden by the new update, thus it’s possible that Touch ID feature was turned off. To make sure this isn’t what’s causing you this trouble, check your iPhone’s Touch ID settings with these steps:

  1. Tap Settings from the Home screen.
  2. Tap Touch ID & Passcode.
  3. Scroll to iPhone Unlock and iTunes & App Store options and make sure they are enabled.

If these options are already enabled, try to turn them off for a few seconds and then turn on again. This trick can help refresh the Touch ID feature and possibly get it back to work as intended.

Second solution: Soft reset/reboot your iPhone 7

Minor software glitches that are triggered by the recent update installation can also halt other features on your device including Touch ID recognition. To clear this out, performing a soft reset or reboot after an update is recommended. If you haven’t done this yet, then follow these steps to soft reset your iPhone 7:

  1. Press and hold the Side/Power button until the Slide to Power Off command appears.
  2. Drag the slider to the right to turn your iPhone completely off.
  3. After 30 seconds, press and hold the Power button until the Apple logo appears and then release.

This won’t delete any data you’ve stored on the internal memory, thus you won’t lose critical information in the process. A soft reset is also a way of clearing cache from the internal memory  including temporary data that were corrupted from the update.

Third solution: Reset all settings on your iPhone 7

Invalid system settings are also among the possible reasons as to why Touch ID may have failed to work. Should the new update quashed your iPhone settings and prevented the feature from carrying out its usual functions, then that should be rectified by this reset. To restore system settings on your iPhone 7 to their original or default values, follow these steps:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset All Settings from the given options.
  5. If prompted, enter your passcode to continue.

Your iPhone should restart by itself when the reset is finished. Then you can start configuring your device and enable features according to your previous preferences, before the problem surfaced. Make sure Touch ID is turned on or activated.

Fourth solution: Reset and restore your iPhone 7 to its factory defaults

A master reset or factory reset can be considered among the last options to try if none of the previous methods is able to offer an ultimate solution. This will wipe everything from your iPhone system including data and information stored on the internal memory. Tough bugs and fatal system errors that might have inflicted troubles particularly on Touch ID will also be cleared in this reset. Should you wish to proceed, back up all your important data for safekeeping and then continue with these steps:

  1. Tap Settings.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Erase All Content and Settings.
  5. If prompted, enter your device passcode to continue.
  6. Then tap the option to confirm reset.

Allow your device to finish resetting. The reset process can take longer depending on the number of files you’ve stored on the phone. Once the reset is complete, your iPhone will restart automatically. As soon as it has completely restarted, you can proceed with the initial setup process. This is when you’ll setup and enable necessary features including Touch ID on your device. Enroll the fingerprint(s) you want to use then test to see if it’s working when done.

Fifth solution: Restore your iPhone 7 through iTunes

If a factory reset should fail to fix the problem or Touch ID is still not working on your iPhone 7, then you can continue to troubleshoot more intricate system issues and this time try a recovery mode restore. This will put your device in a recovery state and then allows it to be restored through iTunes. To get this done, you will need to secure a computer either a Windows PC or Mac, with a later or latest OS and iTunes software installed. Once you’re all set, follow these steps to restore your iPhone 7 in recovery mode:

  1. Connect your iPhone to your computer using the supplied USB connector or Lightning cable and then open iTunes.
  2. While your iPhone is connected, do a force restart by pressing and holding on the Side/Power button and Volume Down button simultaneously for a while. Do not release the buttons when the Apple logo appears because you will need to put your device in recovery mode. You can release the buttons as soon as you see the Connect to iTunes screen.
  3. When prompted with the option to Update or Restore, select Restore.
  4. Wait while iTunes attempts to reinstall iOS and download the software for your device. The download usually takes 15 minutes.  If the download exceeds 15 minutes, your iPhone will exit the Connect to iTunes screen. If that happens, just let the download finish and then go back to the previous steps to get to the Connect to iTunes screen and enter recovery mode again.

Once the recovery mode restore is completed, you can set up your device as new. Follow the same instructions to set up Touch ID and enroll the fingerprints you want to use.

Another option you may consider resorting to if ever a recovery mode restore would fail to resolve the issue is a DFU mode restore. It’s regarded as the deepest type of system restore you can do on an iPhone. It allows your device to be restored and repaired through iTunes even when the operating system is totally corrupted.
