The Samsung Galaxy S8 comes with a number of security features, one of them is facial recognition and it appears that this can be fooled by using a photo.
The video below from the guys over at iDeviceHelp shows the facial recognition on the Samsung Galaxy S8 being bypassed with a photo on another handset.
As we can see from the video the handset was unlocked using a photo on another smartphone, the handset also comes with other security features built in.
Ars Technica reached out to Samsung after the video was released and you can see an official statement from Samsung below.
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.
So whilst it looks like the facial recognition can be used to unlock your device, it cannot be used for making payments or accessing a secure folder.
