PSA: You probably don’t want to use face recognition to unlock your Galaxy S8
The Galaxy S8 is one of the most stunning phones we’ve ever laid eyes on, but there’s one design element we can’t quite wrap our heads around. Instead of centering the fingerprint sensor on the back like so many other phone makers have done, Samsung has placed it next to the camera, virtually assuring that most people will use one of the other myriad ways to unlock.
But the one people are most likely to use is also one of the least secure. Instead of a pattern or a passcode, you can set up your Galaxy S8 to unlock as soon as it sees your face (since you’re likely to be looking at it anyway). It utilizes the front camera to study the proportions of your face and when it recognizes it’s you, it’ll unlock. Think of it like taking a selfie that only your phone will see.
