Huawei Mate 20 Pro has two biometric unlocking methods: a fingerprint sensor in the display and 3D face recognition. Both should be equally safe, but 3D Face Unlock does not work as it should on the Android Pit review sample of the Mate 20 Pro.
The device face unlock feature consistently mistakes one of Android Pit staff members for another on the test device it is using. According to Android Pit, the phone first unlocked when the other employee was simply checking out the device.
In the video below, you can see there are two different faces, with different skin color, different contours, eye color, glasses versus no glasses, and many other differences. They are not twins, not even related, so it’s not that similar. But, both have a full beard and comparatively short hair.
Also multiple deleting and re-learning brings the same result: By the third attempt at the latest, the Mate 20 Pro can be unlocked by both staff members.
Huawei does issue a disclaimer – In the beginning, it says: “It is possible that your device will be unlocked by very similar looking people or objects.” In the past, we were able to easily understand this in 2D recognition. However, with 3D detection, which Huawei estimates are 1: 1,000,000, it should not be so easy.
According to Android Pit, Huawei is already investigating the matter. Huawei points out that they have not yet seen such face recognition behavior, even in the elaborate test procedures that are even performed with twins.
Perhaps the most disappointing thing about this situation is that face unlock is one of the main differences between the Mate 20 and the Mate 20 Pro.
