Face ID is one of the defining features of modern iPhones that allow users to securely unlock their devices with just a glance. However, for various reasons, Face ID may stop working properly on your iPhone 11.
In this guide, we will discuss some common issues that can cause Face ID to fail and provide steps to troubleshoot and potentially fix it.
Why is Face ID Not Working on My iPhone 11?
There can be several potential reasons why Face ID stops recognizing your face on the iPhone 11:
Dirty or Obstructed Face ID Sensors
The TrueDepth camera and infrared sensors used for Face ID can get obscured if the sensors collect dirt, debris, fingerprints or smudges over time. This prevents clear infrared mapping of your face.
Hardware or Software Issues
In some cases, Face ID failure could be due to an underlying hardware fault in the TrueDepth camera, its sensors or related components. iOS software bugs or glitches after an update can also interfere with Face ID functionality.
Changes to Your Appearance
Facial hair growth, weight gain/loss, cosmetic surgery or other significant changes to your face shape/features can confuse Face ID recognition until it re-learns your facial details.
Improper Use or Setup of Face ID
Not positioning your face correctly during enrollment or trying to unlock at unusual angles can cause Face ID to reject your face. Not re-enrolling after major appearance changes is another reason.
Troubleshooting Steps to Fix Face ID on iPhone 11
Before assuming your Face ID sensors are faulty, try these troubleshooting steps to resolve common issues:
1. Clean Face ID Sensors
Use a soft, dry microfiber cloth to gently wipe the front TrueDepth camera and IR sensor area above the display. Avoid using liquids or harsh cleaners.
2. Restart Your iPhone 11
Power off and power on your device by pressing and holding both volume buttons and side button for 10 seconds. This refreshes Face ID components.
3. Reset Face ID Settings
Go to Settings > Face ID & Passcode. Enter your passcode, then tap “Reset Face ID”. You’ll need to re-enroll your face from scratch.
4. Check and Update to the Latest iOS Version
Outdated iOS software can cause glitches. Go to Settings > General > Software Update and install any available updates.
5. Position Your Face Correctly for Enrollment
When resetting Face ID, hold your iPhone 11 12-18 inches away and center your face in the iPhone frame. Avoid covering nose/mouth.
6. Allow Time for Re-enrollment
It may take Face ID a few unlock attempts to re-learn your facial details after resetting. Be patient during this process.
When to Contact Apple Support
If Face ID continues to fail recognition after thorough troubleshooting, it may point to an actual hardware flaw. In such cases, contact Apple support via online chat or phone for diagnosis and next steps.
Apple technicians can run remote diagnostics to determine if TrueDepth camera components need repair or replacement. Out of warranty devices may need to visit an Apple store or service center.
Other Face ID Troubleshooting Tips
A few additional tips that may help fix Face ID issues:
Check for Cracked/Damaged Display
Display damage near TrueDepth camera can obstruct infrared beams. Get the screen replaced from Apple.
Update iPhone to the Latest iOS Beta
Public betas sometimes address latent software bugs before public releases. Consider enrolling if issues persist on public builds.
Avoid Enrolling Under Direct Bright Light
Harsh lighting interferes with infrared sensing. Reduce ambient light sources during Face ID setup.
Try Unlocking from Closer Ranges
Face ID may work from 6-10 inches if further distances fail. It adapts over time to greater ranges.
Conclusion
With a bit of troubleshooting and by following the steps in this guide, there is a good chance of getting Face ID working again on your iPhone 11 if it stops recognizing your face. Do check for any iOS updates and contact Apple support promptly if issues persist even after re-enrollment attempts.
