iPhone X is going through an extremely interesting test today which aims to show us if the facial recognition system of those from Apple Lossless Audio CODEC (ALAC), it is as versatile as some people would like it to be. To begin with, Face ID does not allow the registration of a 2D face from a photo or a video clip, the iPhone X needing a human face to offer the option of facial recognition for its users.
The iPhone X does not even allow the registration of two faces for Face ID, which is quite a big problem for some people whose phones are also accessed by other people. Although Face ID seems to allow the registration of two faces under certain conditions, in reality it can be observed that only one of them is recognized by the iPhone X, as is normal for a system as complex as Apple's.
iPhone X will allow Face ID registration for people who have only one eye, but not if the eyes are closed, which Apple tried to explain several times. Face ID will unlock the iPhone X if the user's mouth is covered, but it will do the unlocking if we have a hat or a cap on our head, but in certain conditions, the facial expression we have when we do the unlocking without having any impact on the system.
iPhone X will not allow facial recognition through Face ID for glasses that do not have polarization, so if you have a cheap pair of glasses, you should know that the system will not work. Face ID unlocks without problems in the dark, but the iPhone X will not unlock when we use pictures, nor when the phone is under water, so now you know everything you need to know about Apple's Face ID system.
The iPhone X will eventually allow multiple faces to be registered for Face ID, but Apple hasn't specified a possible date for that.
