Why has my Face ID stopped working
Apple has created a great facial recognition feature, Face ID, that has allowed users to easily and securely unlock their iPhones. However, over time, even the most reliable technology can run into problems.
If you want to figure out why Face ID isn’t working on your device, this article is for you. We’ll look at all the possible ways to solve the problem and get your iPhone back to working order.
Face ID
Face ID is a biometric authentication system developed by Apple for its smartphones that uses facial recognition technology.
Before its introduction, Apple had already had successful experience in using biometric identification. The first was Touch ID technology, which was widely recognized for its simplicity and reliability. But to maximize security and convenience, Apple sought to develop a new, more advanced technology.
In 2017, Apple introduced Face ID with the iPhone X. It replaced Touch ID and became the primary way to unlock your device, make payments via Apple Pay, and authenticate apps.
Operating principles
- TrueDepth technology . Face ID uses the TrueDepth camera, which includes several elements, such as an infrared camera, a light projector, and a regular camera. These components work together to create an accurate 3D model of your face.
- Infrared Lighting : When you first set up Face ID, the device creates a complex image of your face using infrared beams. A projector creates more than 30,000 invisible dots on your face, and the camera then feeds that data into the system.
- Machine learning : Face ID uses machine learning algorithms that allow the system to adapt to changes in your face over time (for example, if you grow a beard or start wearing glasses).
- Security : Your face data is encrypted and stored on your device in a special secure element called the Secure Enclave. This means that even Apple does not have access to your biometric data.
Why Face ID Doesn’t Work
Before looking for ways to get rid of the problem, it is important to understand why Face ID is not working. There are several reasons why the system may stop recognizing your face:
- Often the cause can be dirt or damage to the TrueDepth camera;
- An old version of the operating system can also be a problem;
- iOS system glitches may temporarily disable Face ID;
- Physical damage to the device may also affect the performance of facial recognition;
- A dramatic change in appearance, such as a beard or a new haircut, can temporarily “fool” Face ID;
- Insufficient lighting may adversely affect system performance.
Ways to solve the problem with Face ID
Simple device restart
The first simple step that many users often forget is to reboot the phone. Restarting can help the system update and get rid of temporary glitches:
For iPhone 8 and newer:
- Press and hold the Side button and the Volume Up/Down button simultaneously;
- Release, then simultaneously press and hold the Side button until the Apple logo appears.
For iPhone 7 and 7 Plus:
- Press and hold the Volume Down button and the Power button until the logo appears.
For iPhone 6s and earlier:
- Press and hold the Home button and the Power button until the Apple logo appears.
Software update
Face ID issues can be caused by software bugs, so it’s important to make sure you have the latest version of iOS.
- Go to “Settings”;
- Select “General”;
- Click on “Software Update”;
- If an update is available, download and install it.
Setting up Face ID
Try setting up face recognition again:
- Go to “Settings”;
- Select “Face ID and Passcode”;
- Enter your password code;
- Tap Reset Face ID;
- Tap Set Up Face ID;
- Follow the onscreen instructions to set up Face ID again.
Make sure Face ID is enabled for the features you want
Sometimes the issue may be related to the settings for which features Face ID is used.
- Go to “Settings”;
- Select “Face ID and Passcode”;
- Make sure the switches for unlocking iPhone, iTunes and the App Store, Apple Pay, and other apps are turned on.
Check the terms of use
Face ID may not work in some lighting conditions and positions. So use it in normal lighting conditions and try to keep your face directly in front of the screen.
Reset settings
If all else fails, you may want to consider resetting your device. Note that this may remove all Wi-Fi, Bluetooth, and personalized settings, but it will not remove your data or apps:
- Go to “Settings”;
- Then “Basic”;
- Next, “Reset”;
- “Reset all settings”.
Contacting Apple Support
If none of the suggested methods helped, the problem may be related to the hardware. In this case, you should contact Apple support or visit an authorized service center for diagnostics and repair of the device.
Describe to them your problem and all the steps you have already taken.
Face ID is a highly advanced security system that makes using iPhone convenient and secure.
Although technical issues may arise, understanding how they work and how to troubleshoot them will help you make changes and ensure that your system continues to function properly.
Be sure to check your device settings and updates periodically to keep Face ID up to date and secure.
