The iPhone 12 has been celebrated for its innovative features, one of which is the highly advanced Face ID technology. However, just like any piece of technology, it isn’t impervious to issues. Many users have reported problems with Face ID not working properly, creating frustration and inconvenience. In this article, we’ll delve deep into the reasons why your iPhone 12 Face ID might not be functioning effectively and explore actionable solutions to restore this essential feature.
Understanding Face ID: How Does It Work?
Face ID is an advanced facial recognition system developed by Apple. It uses the front camera and a set of sensors to map your face and create a 3D model for authentication. When functioning correctly, Face ID allows you to unlock your phone, authenticate purchases, and access secure applications simply by looking at your device.
Face ID operates through a combination of hardware and software:
- TrueDepth Camera System: The camera captures more than just an image of your face; it employs dot projection technology to create a depth map of your face.
- Neural Engine: Apple’s Bionic chip interprets facial data and recognizes changes, even if you grow facial hair or change hairstyles.
Understanding this technology is crucial when troubleshooting the Face ID issues on your iPhone 12.
Common Reasons for Face ID Malfunction
Despite its cutting-edge technology, Face ID can occasionally encounter problems. Here are some common reasons why your iPhone 12 Face ID might not be working properly:

What should I do if my iPhone 12 Face ID is not working?
If your iPhone 12 Face ID is not working, the first step is to check for any obstructions. Ensure that the TrueDepth camera is not covered by a case or any screen protector that might block the sensors. Additionally, clean the front camera area to remove any dust or smudges that may affect its functionality. Try to restart your device, as sometimes a simple reboot can resolve minor software glitches affecting Face ID.
If the issue persists, navigate to the Settings app and check if Face ID is set up correctly. Under Face ID & Passcode, ensure that your face is recognized and that you have enabled the necessary features, such as unlocking your phone and making purchases. If the setup seems correct and you are still experiencing issues, consider resetting your Face ID or updating your iOS software to the latest version, as updates can fix known bugs and improve overall performance.
Can I use Face ID if I’m wearing a mask or glasses?
Face ID is designed to work with various facial features, but wearing a mask can interfere with its functionality. To use Face ID when wearing a mask, you can opt to unlock your device with your passcode instead. Alternatively, Apple introduced a feature allowing Face ID to recognize your face even while wearing a mask, but it may require you to have an Apple Watch for it to work seamlessly.
If you wear glasses, Face ID should still recognize you without issue, as it is designed to adapt to changes in your appearance. However, if you change your glasses frequently, it may be beneficial to set up an alternate appearance to ensure that Face ID can recognize you in different scenarios.
How can I reset my Face ID settings on iPhone 12?
To reset your Face ID settings, go to the Settings app and tap on Face ID & Passcode. You will need to enter your passcode to access this section. Once there, you can select “Reset Face ID” to clear the current facial recognition data. After resetting it, you can set up Face ID again by following the on-screen instructions, which will involve positioning your face within the frame and moving your head in a circle.
Resetting Face ID can be helpful if it is not responding properly or if your face has changed significantly since its last setup. It’s important to have good lighting and ensure that you are in a position where the TrueDepth camera can clearly see your face during the setup process for the best results.
Is Face ID secure on the iPhone 12?
Yes, Face ID is considered a secure method of authentication on the iPhone 12. Apple employs advanced technology using a TrueDepth camera system that maps your face in 3D, making it difficult for other individuals to unlock your phone using a photograph or mask. The facial data is stored securely in the device’s Secure Enclave, which means it does not leave your device and is not accessible to third-party applications.
Additionally, Apple has implemented various measures to protect user privacy. Face ID only activates when you wake your device or when you attempt to unlock it, ensuring that the data is not continuously collected. The potential for false acceptance is incredibly low; in fact, Apple claims the odds of a random person unlocking your phone with Face ID are about 1 in a million.
Why does my iPhone 12 Face ID work intermittently?
Intermittent functionality of Face ID can be frustrating and is often caused by various environmental or software factors. One common issue is the positioning of the device; holding your phone at an awkward angle or not directly facing the TrueDepth camera can prevent successful recognition. Additionally, if you’re in a poorly lit environment or if there are drastic changes in lighting, Face ID may struggle to identify you correctly.
Software issues can also lead to intermittent performance. Make sure your iPhone 12 is running the latest version of iOS, as updates often contain fixes for bugs that could affect Face ID. If the problem continues despite these efforts, consider resetting your Face ID or even performing a factory reset after backing up your data, as this can resolve persistent software-related issues.
What should I do if my iPhone 12 keeps saying “Face ID is not available”?
If you encounter the message “Face ID is not available,” the first action to take is to restart your iPhone 12. Many software issues can be resolved with a simple restart, refreshing the system and potentially clearing any errors that may have caused Face ID to be disabled. After restarting, check to see if Face ID is recognized again in the Settings app under Face ID & Passcode.
If Face ID remains unavailable, consider checking for any software updates in Settings. Installing the latest iOS updates can address known bugs that might be affecting Face ID functionality. If neither of these solutions works, you may want to reset your Face ID settings or consider contacting Apple Support, as the issue could be related to a hardware malfunction requiring professional assistance.
