First solution: Turn Touch ID off and then on again.
The Touch ID feature might have been experiencing minor glitches following the update thus, it stopped working. To clear out minor software glitches, try turning off Touch ID shortly and then turn on again. Here’s how it’s done:
- Tap Settings from the Home screen.
- Tap Touch ID & Passcode.
- Scroll to iPhone Unlock and iTunes & App Store options then toggle the switch to turn these options off and on again.
This trick has been proven effective by other iPhone owners who have dealt with the same issue when using Touch ID. Give it a try and see if it will yield to a positive result. If it doesn’t work on your end, then continue to troubleshoot and try the other applicable solutions.
Second solution: Reboot/soft reset your iPhone 7 Plus.
This is another simple yet very effective solution to minor software errors including those that are transpiring after an iOS update implementation. Restarting your iPhone not only refreshes the operating system but also dumps errant cache from the internal memory that might have caused conflict to other functions like Touch ID. To soft reset/restart your iPhone 7 Plus, follow these steps:
- Press and hold the Side/Power button until the Slide to Power Off command appears.
- Drag the slider to the right to turn your iPhone completely off.
- After 30 seconds, press and hold the Power button until the Apple logo appears and then release.
This won’t delete any personal information you saved on the phone storage, so there’s no need to create backups.
Third solution: Reset all settings on your iPhone 7 Plus.
Your iPhone settings might have been automatically overridden by the new iOS update and eventually resulted to an error. To rectify it, you can revert your iPhone settings back to their original or default values. This can be done through a system settings reset on your iPhone 7 Plus. Here’s how:
- Tap Settings from the Home screen.
- Tap General.
- Scroll to and tap Reset.
- Select Reset All Settings from the given options.
- If prompted, enter your passcode to continue.
- Then tap the option to confirm all settings reset.
Your device will then start deleting the current settings and then restore the defaults. Any erroneous configuration will likewise be cleared in the process. After the reset, you will need to enable options and features you want to use on your device.
Fourth solution: Master reset/factory reset your iPhone 7 Plus.
A master reset or factory reset can be considered among the last options to further troubleshoot more complex system issues on the phone that might have hindered the Touch ID from working. This will wipe everything from your iPhone including your personal information stored on the phone’s internal storage. Before you proceed, back up all critical data for safekeeping. Then follow these steps to master reset or factory reset your iPhone 7 Plus through settings:
- Tap Settings.
- Tap General.
- Scroll to and tap Reset.
- Select the option to Erase All Content and Settings.
- If prompted, enter your device passcode to continue.
- Then tap the option to confirm reset.
Allow your device to complete the entire reset process and then restore the factory defaults. It will restart by itself when the reset is done. As soon as it’s finished booting up, you can continue with the initial device setup process. Don’t forget to set up Touch ID and register fingerprints you want to use.
Fifth solution: Restore your iPhone 7 Plus in recovery mode through iTunes.
If a factory reset/master reset failed to fix the problem and Touch ID is still not working on your iPhone 7 Plus, then you can resort to a recovery mode restore. This will put your device in a recovery state and then restore iOS using iTunes. Here’s how it’s done:
- Connect your iPhone to your computer using the supplied USB connector or Lightning cable and then open iTunes.
- 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.
- When prompted with the option to Update or Restore, select Restore.
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.
You may opt to give a DFU mode restore a shot if Touch ID is still not working on your iPhone 7 Plus after performing a recovery mode restore. This will put your iPhone in a state where it’s still able to communicate with iTunes on a computer even when the operating system isn’t loading. A more detailed walkthrough on how to carry out a DFU mode restore on an iPhone 7 Plus is mapped out on the tutorials section of this site. If you need to know the steps, navigate to the iPhone 7 Plus troubleshooting page then go to the tutorials section and find the topic header.
For other options and more advanced troubleshooting methods, contact your carrier’s tech support. You can also escalate the problem to Apple Support so they can make further assessments and if necessary, develop a fix patch.
If none of these helps, then you may have to consider opting for service. Your device might have obtained some sort of physical or liquid damage from prior incidents of dropping or liquid exposure. While the symptoms might have started to occur following an iOS update installation, it doesn’t always mean that the update is to blame. To find out if the problem is attributed to a damaged hardware, have your iPhone checked by an authorized technician at the Genius bar.
