Well, it happened:

Here's what Samsung has to say about the feature

>The Galaxy S8 provides various levels of biometric authentication, with the highest level of authentication from the iris scanner and fingerprint reader. In addition, the Galaxy S8 provides users with multiple options to unlock their phones through both biometric security options, and convenient options such as swipe and facial recognition. It is important to reiterate that facial recognition, while convenient, can only be used for opening your Galaxy S8 and currently cannot be used to authenticate access to Samsung Pay or Secure Folder.

Not exactly a vote of confidence from the manufacturer, is it?

This is not the first time Android has had face recognition to unlock phones. I remember the first time they tried, it was trivially easy to snap a picture of your colleague and open his phone.

Yes indeed. Face Unlock was apparently from Ice Cream Sandwich and fell for this back in 2011:

That's a beta version and I can't guarantee it was true of the release version, but since all they were working with was the normal front facing camera I doubt they were able to make this secure.
