Are you frustrated by the persistent message on your iPhone 11, “Face ID not available”? You’re not alone. This error can be annoying, especially when you rely on Face ID to quickly unlock your phone and access your favorite apps. In this in-depth article, we’ll delve into the common reasons behind this issue and provide you with practical solutions to get your Face ID up and running again.
The Basics of Face ID
Before we dive into the possible causes of the “Face ID not available” error, let’s quickly review how Face ID works. Face ID is a facial recognition system developed by Apple, which uses a combination of cameras, sensors, and machine learning algorithms to identify and authenticate your face.

Why does Face ID sometimes not work on my iPhone 11?
Face ID is a complex technology that relies on a combination of sensors and cameras to recognize and authenticate your face. Sometimes, the system may not work as expected, leading to the “Face ID Not Available” error. This can be due to various reasons such as incorrect positioning of the phone, inadequate lighting, or even a smudge on the TrueDepth camera lens.
When Face ID is not available, you may need to try again or use an alternative method to unlock your iPhone, such as a passcode or password. It’s essential to ensure that your face is within the recommended distance and angle from the camera, and that there are no obstacles blocking the view. You can also try restarting your iPhone or checking for any software updates, which may resolve the issue.
Can I use Face ID with sunglasses or glasses?
Face ID uses infrared light to map your face, which can be affected by certain types of sunglasses or glasses. If your sunglasses or glasses have a coating that blocks infrared light, Face ID may not work properly. However, most sunglasses and glasses do not have this type of coating, and Face ID should still be able to recognize your face.
If you find that Face ID is not working with your sunglasses or glasses, you can try removing them or using an alternative method to unlock your iPhone. You can also try adjusting the position of your sunglasses or glasses to see if that makes a difference. Apple has also implemented a feature called “Require Attention for Face ID” which requires you to look directly at the TrueDepth camera for Face ID to work.
How do I reset Face ID on my iPhone 11?
Resetting Face ID on your iPhone 11 is a relatively straightforward process. To do so, go to the Settings app, select “Face ID & Passcode”, and enter your passcode. Then, tap on “Reset Face ID” and follow the on-screen instructions to set up Face ID again. This will delete your existing Face ID data and allow you to start fresh.
Keep in mind that resetting Face ID will log you out of all the apps and services that use Face ID for authentication, so you’ll need to log back in using your passcode or password. It’s also essential to ensure that your iPhone is running the latest software version, as this can sometimes resolve issues with Face ID.
Can I use Face ID in landscape mode?
Face ID on iPhone 11 is designed to work in portrait mode, and it may not function correctly in landscape mode. This is because the TrueDepth camera system is optimized for portrait mode, and the angles and sensors are calibrated accordingly.
While it’s technically possible to use Face ID in landscape mode, the accuracy and reliability of the system may be compromised. Apple recommends using Face ID in portrait mode for the best results. If you need to unlock your iPhone in landscape mode, you can use a passcode or password as an alternative.
Is Face ID secure and private?
Face ID is a highly secure and private biometric authentication system. Apple uses advanced security measures to protect your Face ID data, including storing it in the Secure Enclave of the A13 Bionic chip. This means that your Face ID data is encrypted and isolated from the rest of the system, and it’s not accessible by Apple or any third-party developers.
In addition, Face ID uses a random number generator to create a unique identifier for each face, which is then stored in the Secure Enclave. This identifier is not a photograph of your face, and it’s not capable of being reverse-engineered to recreate your original image. Apple takes the privacy and security of Face ID very seriously, and the system is designed to provide robust protection for your personal data.
Can I use Face ID if I have a beard or mustache?
Face ID is designed to work with various facial hair styles, including beards and mustaches. The system uses machine learning algorithms to adapt to changes in your appearance, including changes to your facial hair.
However, if you’ve recently grown a beard or mustache, it’s possible that Face ID may not recognize you initially. This is because the system needs to learn your new appearance. You can try setting up Face ID again, or you can wait for the system to adapt to your new look over time.
Will Face ID work in low-light environments?
Face ID uses a combination of visible and infrared light to illuminate your face, which allows it to work in a wide range of lighting conditions, including low-light environments. The TrueDepth camera system is designed to adapt to different lighting scenarios, and it can adjust its illumination levels accordingly.
However, in extremely low-light environments, Face ID may not work as accurately. This is because the system relies on a certain level of illumination to capture a clear image of your face. If the lighting is too low, you may need to try again or use an alternative method to unlock your iPhone.
