"My Face ID is suddenly not working and not recognizing me. How can I resolve this problem?" Since the iPhone X, Apple has introduced Face ID. It allows users to unlock their iOS devices quickly by scanning their faces. However, if it stops working or works abnormally, you will be locked out of your device. This article shares effective solutions to help you fix this problem and regain access to your iPhone.

Key Takeaways: Fix iPhone Face ID Not Working Quickly

If your Face ID is not working, try these fixes first:

• 1.Restart your iPhone.
• 2.Clean the TrueDepth camera.
• 3.Check Face ID settings in Settings > Face ID & Passcode.
• 4.Turn Face ID off and back on.
• 5.Reset Face ID.

If Face ID still does not work, the problem may be related to screen replacement issues or security features like Stolen Device Protection.

Part 1: How Face ID Works on iPhone

Face ID works on iPhones with both hardware and software. The TrueDepth camera located on the top of your iPhone is used to scan your face. The built-in sensors and components project 30,000 infrared dots onto your face to map curves and wrinkles. Then, the result will be matched with the Face ID. If it has a match, your iPhone unlocks. If not, you are asked to try again or unlock your device with the passcode.

When you cannot unlock your iPhone with Face ID?

• 1.The battery level of the iPhone drops below 10%.
• 2.After restarting your iPhone, the first time you must unlock it with the passcode.
• 3.You must unlock your iPhone with the passcode at least once every week.
• 4.Your iPhone has not been unlocked for more than 48 hours.
• 5.Your iPhone is locked remotely.

Part 2: Why Is Face ID Not Working

As mentioned previously, Face ID relies on a tightly integrated system of sensors, infrared imaging, and machine learning models. If any part of the chain is disrupted, this security measure won't work. The common causes why my Face ID is not available include:

• 1.Your iPhone gets stuck on the lock screen.
• 2.The TrueDepth camera or your face is blocked.
• 3.You set up Face ID incorrectly.
• 4.Face ID is stuck or temporarily freezing.
• 5.Improper settings.
• 6.Software glitches.

Solution 1: Restart Your iPhone

A quick solution to fix Face ID not working on iPhone is restarting your device. That closes all apps and processes on your iPhone, and fixes minor glitches. Moreover, it can improve your iPhone's performance.

Solution 2: Clean Your Camera

If you are prompted Face ID is not available, try again later, remove all block items from your face, like the mask and sunglasses. Plus, ensure your eyes, mouth, and nose are fully visible to the front camera, especially when you are told Face ID is not working, and move the iPhone lower.

Moreover, you'd better remove the screen protector and iPhone case. Plus, you should clean the TrueDepth camera on the top of your device and remove the dirt or dust. They may block the infrared light TrueDepth camera relies on.

Solution 3: Check Face ID Settings

Face ID can be used for unlocking your iPhone, purchasing apps, using Apple Pay, and more, depending on your configuration. If Face ID is not available when you unlock your device, check your settings.

Solution 4: Turn Face ID Off and Back On

If you have enabled Face ID for iPhone Unlock or other cases but Apple Face ID is not working, you'd better re-enable it. While this solution is simple, it can fix the stuck Face ID and other basic issues.

Solution 5: Set up an Alternative Face ID

With iOS 12 and above, you can have up to two Face IDs. While Face ID can learn your face changes and makeup with facial recognition technology. However, if you prefer to face mask, you can set up an alternative Face ID.

Solution 6: Reset Face ID

If your Face ID is still not working on iOS 26, resetting it might be helpful. Bear in mind that resetting Face ID will erase all faces you have saved automatically. iOS won't ask for confirmation.

Solution 7: Turn off Stolen Device Protection

Some users reported that Face ID is not working after Stolen Device Protection is enabled. This feature adds additional security to your device when you take it to unfamiliar locations. It may lead your device to become complete inaccessible.

Part 4: How to Fix Face ID Not Working after Screen Replacement

Face ID is a complex system that includes several components, including the TrueDepth camera, infrared sensors, and a neural engine.

You'd better access Apple or an authorized service provider to purchase a screen or tools and software for your iPhone model. You can ask for help from Apple and see if it would be willing to replace the screen on your iPhone. In some cases, they may refuse to touch iPhones that have been tampered with and have parts installed that are not authentic.

If you are refused, look for a reputable third-party repair service to check your screen and match the Face ID components.

Some people complaint that Face ID is not working after updating to iOS 26. In fact, Apple adds new features and fixes bugs in each update.
