If we change our look, we can adjust the face recognition on the Huawei smartphone to maintain accurate recognition by simply registering a new look in the Face Recognition settings.

Note: Once an alternate look is added/registered, the option will disappear, meaning that no more alternative looks can be set or scanned.
