The “futuristic” face unlock feature on the iPhone X, which can be beaten once in a million times, according to Apple, refused to work on stage.
His second attempt bore the same fruit and left without any other options, the iPhone X asked Federighi to unlock using the outdated pin-code mechanism. Who uses pin codes anymore, right?
THIS IS WHAT HAPPENED EXACTLY THERE
it's worth noting that this can't actually be counted as a failure. If you look close at Apple's demo, the iPhone X is telling Federighi that his passcode is needed to unlock Face ID. Apple's devices do this if they've been restarted, so it's possible that whoever was in-charge of placing the phones on stage, had just powered them up before putting them there. So, it's likely that Face ID didn't fail at all in the first place, and this is simply a ghastly mistake that Apple will likely get over easily, while the world wonders what happened.
