How to Fix iOS 17/18 Face ID Not Working [iOS 17.5, iOS 17.6 Included]

Part 1. Why is My Face ID Suddenly Not Working on My iPhone?

Some people may ask "why is my face id not working?" There are a few common reasons why Face ID may suddenly stop working on your iPhone running iOS 17/18/17.1/17.2/17.3/17.4:

• Software bugs or glitches after upgrading to iOS 18/17/17.1/17.2/17.3/17.4/17.5
• The TrueDepth camera has been blocked or obstructed
• Face ID has been temporarily disabled after too many failed attempts
• Changes to your facial appearance are interfering with Face ID recognition
• Hardware issues with the TrueDepth camera system

Most Face ID problems after upgrading to iOS 18/17/17.1/17.2/17.3/17.4/17.5 are likely caused by software bugs or glitches that can be fixed by troubleshooting the device. Hardware issues with the TrueDepth camera are less common.

Part 2. How Do You Fix Face ID When It Doesn't Work?

Solution 1. Check Supported Devices

Face ID requires specific iPhone and iPad models to work properly. Make sure you have a supported device before troubleshooting further.

Follow these steps to check if your device supports Face ID:

• Verify you have an iPhone X or newer. Face ID is only available on iPhone X and later models. Older iPhones like the iPhone 8 do not have Face ID capabilities.
• For masking wearing support, you need an iPhone 12, 13, 14 or 15 model. Only iPhone 12, 13, 14 and 15 models can unlock with Face ID while wearing a mask.
• For iPads, Face ID is only supported on iPad Pro 11-inch, 11-inch 2nd gen, and iPad Pro 12.9-inch 3rd and 4th gen models.
• Check that you have updated to at least iOS 12 which first introduced Face ID.
• If you have an older unsupported iPhone or iPad model, Face ID will not be available. You will need to use a passcode instead of Face ID.

Solution 2. Verify Face ID Settings

Double check that Face ID is properly set up and enabled in your device settings. Incorrect settings could prevent Face ID from working.

Follow these steps to fix face ID not working on iOS 17/18:

• 1. Open Settings and tap Face ID & Passcode.
• 2. Check if you see the "Reset Face ID" option. If so, Face ID is already set up. If not, you may need to set up Face ID from this menu.
• 3. Ensure the Face ID toggles are enabled for iPhone Unlock, iTunes & App Store, Apple Pay, and Password AutoFill.
• 4. Toggle these on if they were disabled. Proper Face ID functionality requires these settings to be on.
• 5. Tap Reset Face ID if available and re-register your face data. This can clear up issues from a faulty face registration. Ensure you are using a face angle that Face ID recognizes during setup.
