While Face ID is a revolutionary technology, it's not immune to occasional glitches.

The Reasons why Face ID Failed at Times
When the iPhone X was released in 2017, its Face ID feature quickly became a standout innovation, allowing users to unlock their phones with just a glance. However, shortly after launch, many users experienced issues with Face ID not working properly, especially after the iOS 11.2 update. While Apple has since addressed many of these concerns through software improvements, Face ID can still fail from time to time. Here are the most common reasons behind it and the corresponding solutions.
1. Restarting or Powering Off the Device
After restarting or powering off your iPhone, Face ID will be temporarily disabled. Upon reboot, you must enter your passcode to reactivate it. This is a security feature designed to protect your device and data.
2. Inactivity for Over 48 Hours
If you haven’t unlocked your iPhone for more than 48 hours, Face ID automatically disables itself for security reasons. In this case, you’ll need to enter your passcode to regain access. This feature ensures that unauthorized access is minimized if the device is left unattended for long periods.
3. Extended Time Without Face ID Usage
If your iPhone hasn’t been unlocked with Face ID for 6.5 days, and it hasn’t been unlocked with a passcode in the last 4 hours, the system requires a passcode. This scenario often occurs if you rely more on a passcode and seldom use Face ID.
4. Failed Face ID Attempts
When Face ID fails to recognize your face five times in a row, it temporarily disables itself for security purposes. You’ll need to enter your passcode to reset the feature and allow further attempts.
5. Low Battery Levels
Face ID may stop working when your iPhone’s battery level drops below 10%. This is done to conserve power for essential operations. Simply charging your device should resolve the Face ID not working issue in this case.
6. Activation of Emergency SOS
If you activate Emergency SOS by holding the side button and a volume button for two seconds, Face ID will be disabled until you enter your passcode. This is another security measure designed to prevent unauthorized access during emergencies.
7. Hardware or Obstruction Issues
The TrueDepth camera is vital for Face ID functionality. If the camera is blocked by dirt, a screen protector, or physical damage, Face ID won’t work correctly. Regularly clean the camera area and check for any obstructions to resolve the Face ID not working issue.
8. Lighting or Environmental Conditions
Face ID performs best in moderate lighting conditions. Extreme brightness or darkness can interfere with its recognition capabilities. Direct sunlight can also affect the TrueDepth camera, so try to use your iPhone in balanced lighting to avoid Face ID not working problems.
9. Changes in Appearance
Significant changes in your appearance, such as wearing a mask, sunglasses, or heavy makeup, can confuse Face ID. Consider setting up an Alternative Appearance in the Face ID settings for better recognition under varying circumstances.
10. Remote Commands or Security Restrictions
If a remote lock command is sent via 'Find My iPhone' or if your device is subject to enterprise security settings, Face ID will be temporarily disabled. You’ll need your passcode to unlock the device and resume normal operation.
8 Solutions for Face ID Not Working
If you're encountering the frustrating issue of Face ID not working, there are several steps you can take to resolve it. Below are eight practical methods to help you fix this problem effectively.
1. Update Your iOS
Keeping your iPhone’s iOS updated is essential for ensuring that features like Face ID work properly. Apple often releases updates to fix bugs and improve performance.
• Steps to update:
Go to Settings > General > Software Update and install the latest version. By updating your device, you may resolve the Face ID not working issue caused by software glitches.
2.Check Face ID Settings
If Face ID isn't working, it’s worth checking whether the feature is enabled in the settings.
• How to check:
Go to Settings > Face ID & Passcode and ensure that Face ID is turned on for unlocking your iPhone, Apple Pay, and other apps. Additionally, if you’ve had significant changes to your appearance, set up an Alternative Appearance under the same menu to improve Face ID recognition.
3. Reset Face ID
Resetting Face ID can often fix configuration issues.
• Steps to reset:
Navigate to Settings > Face ID & Passcode, tap “Reset Face ID,” and follow the on-screen instructions to set it up again. This is a simple yet effective way to address the Face ID not working problem.
4. Restart Your iPhone
Restarting your device can fix temporary glitches that may cause Face ID to fail.
• How to restart:
On iPhones with Face ID: Press and hold the side button and either volume button until the power slider appears. Drag the slider to turn off your device, wait a few seconds, and turn it back on. Restarting is a quick way to resolve Face ID not working issues.
5. Ensure Proper Face Positioning
Face ID requires you to be properly positioned in front of the TrueDepth camera.
• Tips for proper positioning:
Hold your iPhone 10-20 inches from your face and ensure the camera is unobstructed by cases, dirt, or debris. Also, ensure that you are in moderate lighting conditions, as extreme lighting may affect the camera's accuracy. Improper positioning is a common cause of the Face ID not working issue.
6. Reset All Settings
If the above methods don’t work, resetting all settings can help. This will not erase your data but will reset preferences such as Wi-Fi passwords and display settings.
• Steps to reset settings:
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This is a more advanced solution for persistent Face ID not working problems.
7. Clean the TrueDepth Camera
The TrueDepth camera is essential for Face ID to function correctly. Dirt, smudges, or a screen protector can obstruct the camera and cause it to fail.
• How to clean the camera:
Use a soft microfiber cloth to gently clean the camera area and remove any obstructions. Ensure the camera is not covered by a case or screen protector. This simple maintenance can often fix the Face ID not working issue.
8. Contact Apple Support
If none of these solutions work, the issue might be hardware-related. Problems with the TrueDepth camera or internal components can prevent Face ID from functioning.
• What to do:
Visit an Apple Store or an authorized service provider for a professional diagnosis and repair. This is the final step if all other fixes for the Face ID not working problem fail.
By following these steps, you can effectively resolve the Face ID not working issue and restore the smooth unlocking experience your iPhone offers.
Face ID Not Available on iPhone X
The "Face ID is not available" error is a more serious issue than standard recognition failures, as it completely prevents Face ID setup and usage on iPhone X. This problem became particularly common after certain iOS updates and can stem from both software bugs and hardware damage.
Why This Issue Occurs
1. TrueDepth Camera System Damage
Physical damage to the TrueDepth camera components, water intrusion, or manufacturing defects can disable Face ID entirely. Unlike temporary failures, these hardware issues prevent the facial mapping system from functioning.
2. Third-Party Screen Replacement
This is the most common cause of "Face ID not available" on iPhone X. Unauthorized screen repairs often damage the delicate TrueDepth flex cables or fail to properly transfer original components. Additionally, Apple's security measures may permanently disable Face ID when non-genuine parts are detected.
3. Software Corruption
iOS update failures, corrupted system files, or firmware inconsistencies can trigger this error, though these are less common than hardware-related causes.
How to Fix It
Quick Software Fixes
- Force Restart: Press and release Volume Up, press and release Volume Down, then hold the Side button until the Apple logo appears
- Update iOS: Go to Settings > General > Software Update and install the latest version
- Reset All Settings: Navigate to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings (this won't delete your data)
If Software Fixes Don't Work
- Check for physical damage: Remove screen protectors, clean the TrueDepth camera area, and inspect for visible damage
- If previously repaired: Face ID only works with repairs done by Apple or authorized providers. Third-party repairs often cause permanent Face ID failure
- Contact Apple Support: Hardware issues require professional diagnosis. Schedule an appointment for TrueDepth camera system inspection
Important Notes
- Always use Apple or authorized service providers for repairs to maintain Face ID functionality
- If the problem persists after software troubleshooting, it's likely a hardware issue requiring professional repair
- Out-of-warranty TrueDepth camera repairs can be expensive, but are often the only solution for hardware-related Face ID unavailability
Conclusion
Dealing with Face ID not working on iPhone or seeing "Face ID not available on iPhone X" can be frustrating, but most issues are solvable through the solutions outlined above. Whether you're facing a Face ID issue detected message or experiencing iPhone X Face ID not working after a repair, understanding the root cause helps you choose the right fix.
