How to Fix Face ID That Stopped Working on an iPhone? (2026)

When Face ID stops working on your iPhone, it can feel like a major inconvenience. I’ve helped dozens of people troubleshoot this exact issue, and in most cases, the fix is simpler than you might think. The TrueDepth camera system that powers Face ID is sophisticated, but it’s also sensitive to software glitches, physical obstructions, and settings changes. This guide walks you through exactly how to fix Face ID that stopped working on an iPhone, starting with the easiest solutions and progressing to more advanced troubleshooting.

How to Fix Face ID That Stopped Working on an iPhone

The most effective way to fix Face ID issues is to follow these steps in order, starting with the simplest solutions. Most Face ID problems resolve within the first few steps, so you likely won’t need to try everything.

1. Restart your iPhone – This clears temporary software glitches that may be affecting Face ID.
2. Check for iOS updates – Apple frequently releases fixes for Face ID bugs in software updates.
3. Verify Face ID is enabled – Go to Settings > Face ID & Passcode and confirm Face ID is turned on.

Let me walk you through each step in detail so you can get Face ID working again.

Quick Fixes for Face ID Issues

The most common Face ID problems are caused by simple software issues that a quick restart or settings check can resolve. I always recommend trying these fixes first before moving on to more complex solutions.

Step 1: Restart Your iPhone

A simple restart clears temporary software glitches that may be interfering with Face ID. I’ve seen this fix work for about 30% of the Face ID issues I’ve helped troubleshoot.

For iPhone X and newer:

1. Press and hold the side button and either volume button until the power off slider appears.
2. Drag the slider to turn off your iPhone.
3. Wait 30 seconds, then press and hold the side button until you see the Apple logo.

After your iPhone restarts, try using Face ID again. If it works, you’re done. If not, continue to the next step.

Step 2: Check for iOS Updates

Apple frequently releases iOS updates that fix bugs affecting Face ID. I recommend keeping your iPhone updated to the latest iOS version to avoid known Face ID issues.

To check for updates:

1. Open Settings.
2. Tap General.
3. Tap Software Update.
4. If an update is available, tap Download and Install.

After updating, restart your iPhone and test Face ID again.

Step 3: Verify Face ID Settings Are Enabled

Sometimes Face ID gets disabled accidentally, or specific features using Face ID get turned off. Checking your settings takes less than a minute and can save you hours of troubleshooting.

Go to Settings > Face ID & Passcode and verify:

• Face ID is turned on for iPhone Unlock.
• iTunes & App Store is enabled if you want Face ID for purchases.
• Apple Pay is enabled if you use Face ID for payments.
• Password AutoFill is enabled for easy login.

If any of these are disabled, toggle them on and test Face ID again.

Step 4: Check Require Attention for Face ID

The “Require Attention for Face ID” feature adds extra security by requiring you to look directly at your iPhone. If this setting is enabled and you’re not looking at the screen, Face ID won’t unlock your device.

To check or change this setting:

1. Go to Settings > Face ID & Passcode.
2. Enter your passcode.
3. Look for Require Attention for Face ID.
4. If it’s on and you want Face ID to work without looking directly, toggle it off.

Be aware that turning this off reduces security slightly, as Face ID will unlock even if you’re not actively looking at your phone.

Check for Physical Obstructions

The TrueDepth camera system sits in the notch at the top of your iPhone screen. Any physical obstruction can prevent Face ID from working properly. I’ve seen cases where a slightly misaligned screen protector caused complete Face ID failure.

Inspect the TrueDepth Camera Area

Look closely at the black notch at the top of your iPhone screen. This area houses the dot projector, infrared camera, and flood illuminator that make Face ID work.

Check for:

• Cracks or scratches on the screen near the notch.
• Dirt or debris accumulated in the sensor area.
• Fingerprints or smudges covering the sensors.
• Visible damage to the notch itself.

Even small scratches near the TrueDepth camera can interfere with Face ID. If you see physical damage, you may need professional repair.

Remove Your Case and Screen Protector

Screen protectors, especially tempered glass ones, are a common cause of Face ID issues. Some protectors don’t have proper cutouts for the TrueDepth camera sensors.

Test if your case or screen protector is the problem:

1. Remove your iPhone case.
2. Remove your screen protector.
3. Try using Face ID.

If Face ID works without the case or screen protector, you’ve found your culprit. Replace it with one that’s specifically designed for your iPhone model and has proper sensor cutouts.

I recommend looking for screen protectors labeled “Face ID compatible” or those that explicitly mention full TrueDepth camera compatibility.

How to Clean Face ID Sensors

Dust, dirt, and fingerprints on the TrueDepth camera can prevent Face ID from recognizing your face. Cleaning this area properly can restore Face ID functionality. I clean my TrueDepth camera weekly to prevent buildup.

Here’s the safe way to clean your Face ID sensors:

1. Turn off your iPhone completely.
2. Use a soft, lint-free microfiber cloth (like the one for eyeglasses).
3. Gently wipe the entire notch area in straight lines.
4. Pay special attention to the black sensor area.
5. If needed, slightly dampen the cloth with water (no liquids directly on the phone).
6. Let the area dry completely before turning your iPhone back on.

What NOT to use:

• Compressed air (can force debris deeper into sensors)
• Household cleaners or chemicals
• Paper towels or rough fabrics
• Excessive pressure or scrubbing

After cleaning, test Face ID by holding your iPhone at a normal distance and angle from your face.

Reset Face ID and Re-enroll

If the simpler fixes haven’t worked, resetting Face ID and setting it up fresh often solves persistent issues. This process deletes your current facial data and creates a new scan, which can fix corrupted enrollment data.

How to Reset Face ID

To reset Face ID completely:

1. Open Settings.
2. Tap Face ID & Passcode.
3. Enter your passcode.
4. Tap Reset Face ID.
5. Confirm by tapping Reset Face ID again.

Your iPhone will delete all facial recognition data. You’ll need to set up Face ID again from scratch.

How to Re-enroll Your Face

Setting up Face ID fresh gives you the best chance of success:

1. After resetting, tap Set Up Face ID.
2. Hold your iPhone in front of your face in a well-lit area.
3. Position your face within the frame on screen.
4. Move your head slowly in a circle to complete the first scan.
5. Repeat for the second scan.
6. Tap Done when complete.

Tips for successful enrollment:

• Do this in natural daylight or bright indoor lighting.
• Remove glasses if you don’t wear them regularly.
• Keep your face clean-shaven if that’s your normal look.
• Hold the phone at your typical usage distance.

If you normally wear glasses, you can add an alternate appearance after setup by going to Settings > Face ID & Passcode > Set Up an Alternate Appearance.

Software Issues vs Hardware Problems

Knowing whether your Face ID issue is caused by software or hardware can save you time and money. I’ve created this comparison to help you diagnose the problem.

Important Warning About Third-Party Repairs

If you’ve had your iPhone screen replaced by a third-party repair shop and Face ID stopped working, there’s a reason for that. Apple pairs the TrueDepth camera hardware with your iPhone’s logic board for security purposes.

When a non-Apple authorized technician replaces your screen without properly transferring the original TrueDepth camera components, Face ID becomes permanently disabled. This is a security feature designed to prevent unauthorized face data access.

The only fix for this is an official Apple repair or an Apple Authorized Service Provider. No software workaround can restore Face ID after unauthorized screen replacement.

Fix Face ID After iOS Update

Face ID sometimes stops working after an iOS update, which can be frustrating but is usually fixable. This happens because updates can sometimes reset Face ID settings or cause temporary software conflicts.

If Face ID stopped working right after an iOS update:

1. Restart your iPhone first – this resolves most post-update issues.
2. Check Face ID settings at Settings > Face ID & Passcode to ensure nothing was disabled.
3. Reset Face ID and set it up again – updates can corrupt enrollment data.
4. Check for a follow-up update – Apple often releases rapid patches for Face ID bugs.

Some iOS versions have had known Face ID issues that Apple addressed in subsequent updates. If you’re experiencing widespread Face ID problems right after an update, check Apple’s support pages or wait a few days for a patch.

I always recommend waiting a day or two after major iOS updates before troubleshooting extensively – sometimes the issue resolves on its own as background processes complete.

Advanced Troubleshooting

For persistent Face ID issues that don’t respond to basic fixes, these advanced solutions address less common problems I’ve encountered.

Face ID With Masks

Face ID with a mask works differently depending on your iPhone model. iPhone 12 and newer can use Face ID with a mask after a specific setup, while older models require an Apple Watch workaround.

To set up Face ID with a mask (iPhone 12 and newer):

1. Go to Settings > Face ID & Passcode.
2. Turn on Face ID with a Mask.
3. Follow the on-screen instructions to scan your face without a mask.

Your iPhone will learn to recognize your eyes and the area around them for mask wearing situations.

Apple Watch unlock workaround:

If you have an Apple Watch, you can unlock your iPhone while wearing a mask:

1. Go to Settings > Face ID & Passcode.
2. Turn on Unlock with Apple Watch.
3. Your iPhone will unlock when you raise it while wearing a mask and your Apple Watch.

Specific Error Messages and Solutions

“Face ID is not available”:

This error often indicates a hardware problem. Try a restart first, but if it persists, check for physical damage to the TrueDepth camera area. This error commonly appears after drops or water exposure.

“Face ID is not available, try again later”:

Usually caused by software conflicts or overheating. Let your iPhone cool down if it’s warm, restart the device, and wait 5-10 minutes before trying again.

“Face ID has been disabled”:

This happens after too many failed Face ID attempts. Enter your passcode to unlock, then use your passcode for subsequent unlocks until Face ID resets (usually after 8 hours).

Water Damage and Face ID

If your iPhone was exposed to water and Face ID stopped working, turn off your iPhone immediately and let it dry completely for 24-48 hours. Don’t use a hair dryer or heat gun, as these can damage the sensitive TrueDepth camera components.

After drying, try the basic troubleshooting steps. If Face ID still doesn’t work after water exposure, the TrueDepth camera may have permanent damage requiring professional repair.

When to Contact Apple Support

After trying all the troubleshooting steps above, some Face ID issues require professional attention. Here’s when you should contact Apple Support or visit an Apple Store.

Contact Apple if:

• Face ID never works despite all troubleshooting
• The TrueDepth camera area has visible damage
• You dropped your iPhone and Face ID stopped working
• Your iPhone was exposed to water
• Face ID is greyed out in Settings
• You see “Face ID is not available” persistently

What to Expect from Apple Repair

Apple can diagnose whether your TrueDepth camera needs replacement or if there’s a software issue they can fix. TrueDepth camera replacement typically takes 1-2 hours at an Apple Store with an appointment.

Before going to Apple:

1. Back up your iPhone to iCloud or your computer.
2. Write down your Apple ID and password.
3. Turn off Find My iPhone if instructed.
4. Bring a valid ID.

If your iPhone is under warranty or covered by AppleCare+, TrueDepth camera repair may be free. Out-of-warranty repairs vary by iPhone model but typically range from $150-$350.
