Yes, it has. However, it is less secure than Apple's and would probably be crackable with a good photo. But it works very quickly and reliably. Since Face Unlock is only for India and not Europe, you have to change the region to India under Settings>Additional Settings>Region.
Advantages: Face Unlock is activated
Disadvantages: 1. the time is not correct for a short time, but it automatically changes back to Swiss time after a short time. 2. 3 apps made for India are installed, 2 of them you can uninstall right away, the third one is the Xiaomi App Store, which you can't delete (but don't worry, it's only 17 MB).
Have fun with Face Unlock :-)
