A dirty screen protector edge or a quick reboot can fix many Face ID glitches.
- Clean the front camera and sensor area gently.
- Restart the iPhone 16.
- Unlock it and test Face ID again.
Method 2: Check Face ID settings
The update may have changed Face ID permissions for unlock, App Store, or apps.
- Open Settings > Face ID & Passcode.
- Make sure Face ID is enabled for the features you use.
- Confirm no Screen Time restrictions are blocking it.
Method 3: Add an alternate appearance or set up Face ID again
Rebuilding the face model often fixes update-related recognition failures.
- Open Settings > Face ID & Passcode.
- Tap Reset Face ID.
- Set Face ID up again in normal indoor lighting.
Method 4: Turn off Attention Aware Features temporarily
If Face ID works inconsistently, attention detection may be the part failing.
