The face unlock function needs to be adapted according to the facial features. If you wear a mask, you may not be able to unlock it. It is recommended that you use the face unlock function by revealing more facial features in a safe environment.
Here are some of the specific reasons why face unlock doesn't work with masks:
Masks can block the sensors. The sensors used for face unlock are typically located on the front of your device, and they need to be able to see your face clearly in order to work. However, when you wear a mask, it can block the sensors, making it impossible for them to capture the necessary data.
Masks can change the shape of your face. Masks can alter the shape of your face, making it difficult for your device to recognize you. This is especially true if you wear a mask that covers your nose and mouth, as these are two of the most important features used for face recognition.
Masks can reflect light. Masks can reflect light, which can interfere with the sensors used for face unlock. This can make it difficult for your device to get a clear image of your face, even if the sensors are not blocked.
