How to Fix iPhone 16 Pro Face ID Broken After iOS 18.6.2

Several iPhone 16 Pro users report that Face ID has stopped working or become unreliable after a software update. These troubleshooting steps address the most common causes of Face ID failures.

Fix #1: Re-Register Face ID

Face ID data on the iPhone 16 Pro can become corrupted after an update. Resetting it forces a fresh enrollment.

1. Go to Settings > Face ID & Passcode.
2. Enter your passcode.
3. Tap Reset Face ID.
4. Tap Set Up Face ID and follow the on-screen instructions to enroll your face again.

Fix #2: Clean the TrueDepth Camera

Dirt, oil, or screen protector edges covering the TrueDepth camera array above the display can block Face ID.

1. Use a clean, lint-free cloth to wipe the top of the screen where the front camera and sensors are located.
2. If you have a screen protector, make sure it is not covering the sensor area.

Fix #3: Force Restart

A force restart can resolve temporary Face ID sensor failures.

1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Press and hold the Side button until the Apple logo appears.

Fix #4: Update iOS

Apple has fixed Face ID bugs in past iOS updates.

1. Go to Settings > General > Software Update.
2. Install any available update.

Fix #5: Reset All Settings

If Face ID broke after an update, resetting all settings can restore it without erasing data.

1. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.

Fix #6: Contact Apple Support

If Face ID still does not work after a factory reset and fresh Face ID enrollment, the TrueDepth camera module may be faulty. Visit an Apple Store for hardware diagnostics.
