How to Fix iPhone Face ID Not Working

Step by step

1. 2 min

   Clean the TrueDepth camera system

   Use a clean, dry microfiber cloth to gently wipe the notch area at the top of your iPhone screen. Remove any dirt, makeup, or screen protector residue from the front-facing camera and infrared sensors. Avoid using liquids or compressed air.

   Note: Face ID uses invisible infrared light, so even transparent smudges can block recognition.

   Check Face ID settings and requirements

   Open Settings > Face ID & Passcode and enter your passcode. Verify that iPhone Unlock is enabled. Ensure you're holding the phone 10-20 inches from your face in portrait orientation with eyes open and looking directly at the screen.

   Note: Face ID works best in normal lighting conditions and may struggle in complete darkness or very bright sunlight.

   Reset Face ID completely

   Add an alternate appearance

   Return to Settings > Face ID & Passcode and tap Set Up an Alternate Appearance. Scan your face again, this time with any accessories you frequently wear like glasses, hats, or masks. This improves recognition accuracy across different looks.

   Note: The alternate appearance feature can also help if your appearance has changed significantly since the original setup.

   Contact Apple Support for hardware issues

   If Face ID still fails after software troubleshooting, the TrueDepth camera system may have hardware damage. Use the Apple Support app or visit apple.com/support to schedule a diagnostic appointment at an Apple Store or authorized service provider.

   Note: Face ID hardware repairs typically require replacing the entire front camera module and must be performed by Apple to maintain security features.
