Not really, it is very quick and very accurate once setup and actually far more secure than ANY Facial recognition, including Face ID.
Is there a full review of FaceID by a security analyst? IIRC the review units (if they exist) are all still under embargo. I also thought the S8 has been hacked already, and by multiple groups?
Sure, it’s only a matter of time before the X is, but saying it is far less secure than Samsung’s tool is a bit early, especially considering the X hasn’t been tested yet.
And I can unlock the Note 8 the same way or with a fingerprint, in other words, I get my choice and I choose how secure or insecure I am willing to be.
You also have choices on the X, though it is more limited. You have 2 options of how FaceID will work, and, you can also completely disable it, always requiring a passcode.
One thing it can do (still to be proven by reviews), is allow a user to walk up to the device, issue a voice command, have it unlock, and execute all without touching the device, or, holding it up to your face.
Face ID also works in complete darkness, again reportedly. While the Samsung system can too, the screen needs to first turn on, and still requires exact placement of your eyes in front of the device.
I personally like the Samsung technology having used it, but I am also open to giving FaceID a chance before passing judgement
