iPhone X’s headlining feature is a new depth-sensing facial recognition capability afforded by a TrueDepth camera system hidden in the notch at the top of the OLED display.

But Apple appears to have flubbed its first demo of that important post-Touch ID technology during yesterday’s keynote at the Steve Jobs Theater, putting its software engineering chief Craig Federighi, who was demoing the feature, in an awkward situation.

Here’s that odd moment.

People who have taken a closer look at the footage have observed that it likely wasn’t Federighi’s fault because he picked up a phone that appeared to had just been restarted. As you know, for security reasons, after an iPhone is restarted the system always requires that the user punch in a passcode before Touch ID or Face ID is enabled.

If you watch the video intently, you’ll notice that there’s a message on the screen saying “Your passcode is required to enable Face ID,” indicating Face ID might not have been authorized with a passcode after the phone was restarted.

Most of the reviews I’ve seen online sing praises for Face ID, noting that the feature “just works,” but we’ll of course have to wait until iPhone X arrives and we stress-test the feature under various conditions to see how well it really works.

In the meantime, here’s a much better example of Face ID in action.

In the video embedded below, 9to5Mac’s Jordan Kahn is given a quick demo of Face ID by an Apple employee in a hands-on area after the keynote. As you can see for yourself, Face ID works without any hiccups and unlocks the device in an instant.

Apple says the chance of someone unlocking your iPhone X with their face is one in a million. By contrast, the odds of someone cracking Touch ID by having a fingerprint similar enough to yours are about 1 in 50,000, as per the company.

Face ID takes advantage of the new depth-sensing camera system on the front face of the phone which shoots 30,000 invisible dots onto your face. They’re picked up by an infrared camera that builds your unique facial map, using artificial intelligence to verify it’s you.

Your facial map is stored encrypted and safely walled off from the rest of the system inside the Secure Enclave portion of the A11 Bionic chip, like Touch ID.

iPhone X also has a new flood illuminator sensor that kicks into action in low-light situation, using invisible infrared light to help identify your face in darkness. Apple even asked Hollywood special-effects specialists to help it secure Face ID.

They’ve created some very realistic recreations of human faces that Apple says couldn’t bypass Face ID. According to the company, if you do have an evil twin you should use passcode security instead.

What are your thoughts on Face ID thus far?

    Any word on whether we can choose to not swipe up after unlocking? With Touch ID it just unlocked. This needs two steps. I hope we can turn the swipe up option off in settings if we use Face ID.

    • :D

      It was frustrating just watching him swipe up on the stage lol

      • Tony Trenkle Jr.

        Yessss! I agree! I was like that’s TWO steps…but I guess we’ll find out if there’s a setting or not

    • kaliente

      In such case you can’t view your notifocations, because phone unlocks instantly

      • Tony Trenkle Jr.

        That’s why they added a tap on the screen to turn on.

      • kaliente

        Nope, this is why they have added swipe up instead of home button. Otherwise it would interfere with raise to wake.

      • :D

        Maybe a swipe to unlock without having to tap first (one step) would be fine. That way you can still tap to just view the lock screen.

      • Thats why there’s raise to wake feature.

      • :D

        But then you have to raise it, wait for it to turn on, if it hasn’t already, then swipe to unlock. If you could just swipe while raising or taking it out if your pocket then that would be much faster. The actual face detection is extremely fast.

      • kaliente

        That’s why raise to wake exists. I am just curious what kind of settings do FaceID have.

    • Vishnu Reddy

      Yeah 2 steps to unlock is painful.

      • Tony Trenkle Jr.

        The sarcasm is strong with this one.

  • 9to5Slavery

    I’m very upset that I have

    to swipe down for control center

    • :D

      That kinda makes sense though since the Bluetooth, WiFi etc. statusbar icons are on the top right

      • 9to5Slavery

        Swiping down already is a pain. Now it’s full screen you have to swipe down even more. The control center settings was different from android where they were on the swipe based on ergonomics. Now it’s not universially ergonomic at a fair scale no more.

  • Vishnu Reddy

    Any idea, how the reachability feature might work on the iPhone X?

    • Tony Trenkle Jr.

      They confirmed it’s not there.

  • Martynet

    I wonder how does it work when the font is on the table. Do I just tap the screen and iPhone will unlock?

    • Donovan

      Pick it up, it unlocks. Put it down, it locks. Can’t use it while gaming or something cuz you have to look at it.

  • Tommy

    so what about the dudes who like to go between slick face, goatee & full beards? will it work if i have a full beard and then shave completely?

    • Arturo Polanco

      if u watch the keynote they talk about beards and hats or new haircut…. it will work anyways
