How to Fix iPhone X Face ID Not Working

1. Check if the TrueDepth camera is covered with a case, a screen protector, residue or dirt.

2. Ensure that your eyes, nose, and mouth are fully visible to the TrueDepth camera.

3. Face ID is designed to work with many glasses. However, if you are wearing the glasses that block certain types of light, then you can remove it for trying.

4. To make Face ID work perfectly, your iPhone X must be in portrait orientation.

5. Keep your iPhone at arm’s length or closer (10-20 inches) from your face.

6. When you are outside in bright sunlight, make sure to change the position of your iPhone 10 so that the sun isn’t directly behind you.

Besides iPhone X Face ID failing, our team has also collected other common questions, or issues related to Face ID, you may concern about. Check them now.

Will iPhone X Face ID Work in the Dark

Just like touch ID, no matter no light, or low light, your face remains scannable to iPhone X Face ID, with a flood illuminator. Then the dot projector captures you with 30,000 points for identification purposes. There is no need to worry about how the light is, as long as you look at the TrueDepth camera directly, and you can unlock it.

Can iPhone X Face ID Work through Scarves, Beards, Glasses, Sunglasses

When you set up iPhone X Face ID, iPhone X will just memorize the face with the dressing up then. Does it still recognize you when you change, such as scarves, beards, glasses, etc?

iPhone X Face ID uses the Neural Network block in Apple’s A11 Bionic system-on-a-chip, it continually learns and adapts to how your face, facial hair, hairstyle, and facial coverings vary over time.

With the dot projector making up to 30,000 points available, there’s a lot of data for Face ID to work with. Apple also built and tested the system to make sure it works under the widest varieties of conditions possible.

Does iPhone X Face ID Work with Touch ID Apps

We know that all of apps at App Store are allowed to download with touch ID. So on iPhone X, without touch ID, can we still access the apps?

Yes, touch ID apps will also work with Face ID. Apple has abstracted away from the implementation details and simply lets the app ask for biometric authentication. If the ID matches, the app will be authorized.

App developers can also require Face ID for the second factor insecure apps, and generate and use ECC keys inside the Secure Enclave that can be unlocked by Face ID.

How Animoji Works with iPhone X Face ID

Animoji is another amazing feature to bring fun to users. But how does the Animoji work? Apple has a separate system, built into ARKit. It provides basic face tracking for Animoji. All it does is provide rudimentary mesh and depth data, though. It never touches Face ID data or the Face ID process.

The Bottom Line

By applying these methods above, you can totally fix iPhone X Face ID not working. Also if you have found other practical methods, please share it in the comments, to help more users. And if you find this guide working for you, also please share it with others, to help more. Thanks.
