Apple reduced accuracy of key Face ID component in order to have iPhone X on time

Apple's iPhone X security relies hugely on a brand new feature that has never before been put in a phone: 3D face recognition, or Face ID. An array of complex sensors projects more than 30,000 infrared dots onto a person's face to create a detailed 3D facial map. Apple proudly said the probability of someone else unlocking an iPhone with Face ID is 1 in 1,000,000, much more secure than the 1 in 50,000 chance with Touch ID fingerprint recognition.

But when it came to actually making the iPhone X on time and the tight deadlines, Apple was about to stumble badly.

In order to fix dire supply chain issues, Apple has allegedly quietly told suppliers they can reduce the accuracy of Face ID to make it easier to manufacture, according to a report by Bloomberg.

The "solution" came as November 3rd, the official iPhone X launch date looms closer. And some analysts claim that even with this reduced quality of Face ID recognition, Apple will only have 2 to 3 million phones on launch day, and between 25 and 35 million for the traditionally strong holiday quarter. Initially, those estimates stood at 40 million, but supply chain difficulties brought them down.

The 3D Face ID sensor consists of three key elements: a dot projector, flood illuminator and infrared camera. The flood illuminator fires infrared light, illuminating the face, and the camera uses that light to recognize a face. The dot projector then flashes 30,000 dots on the face and the light that is bounced back is used to determine whether the pattern matches an already registered face. It is this dot projector at the third stage of Face ID that is creating trouble for Apple's production. Manufacturing it requires great precision between the dot projector itself and the glass lens on top of it, and even a micron of a difference could cause inaccurate results.

This current report says that at some point in the manufacturing, the technology was so hard to make that only 20% of what was being rolled off the production line actually worked. LG and Sharp were tasked to make the innovative projector. LG Innotek has recently just confirmed that mass production is just beginning

"That technology is something we have been looking at for five years. We had prototypes that were this big," Apple chief designer Jony Ive said earlier referring to around a foot-long prototype.

To ease all of those worries, Apple has relaxed requirements for the new technology and it is not yet clear whether and/or how this will affect the quality of the face scans.

We have seen Apple struggling making enough devices in the past as well: the AirPods are one clear example, but also some iPhone colors like Jet Black and some Apple Watch models, but it's the first time that Apple is expected to have such a setback on a hugely important model in its most important quarter of the year.

I want this thing to release. I am curious to see how accurate Face ID really is.

They had to reduce its accuracy, because it would fail too many times. Which defeats the purpose of having something replace Apple's TouchID altogether, especially when it fails and backs up to using your password. Then why have FaceID in the first place. So the real reason is the amount of failures when it scans. Anyone with half a brain realized that a finger print scanner is going to be much faster and more reliable than facial recognition. It comes down to small amounts of more static data (TouchID), verses large amounts of more variable data.

I've stated that soooooo many times. Only you and I agree because be have brains and actually understand how tech works. We aren't just platform fans.

Funny how iPhonearena say 'allegedly' No iPhonearena it's FACT Apple are trying to cover up the story by denying it Their shares have fallen due to this story so why aren't the 'ill sue you' trigger happy apple suing Bloomberg? Because they can't because the truth would come out that they did reduce the reliability of the face id Lol apple are the shadiest This is a company charging 80pounds for a charger to quick charge your phone.. Face id is a bigger risk now it's been reduced in quality, finger print scanner on the back would have been the better option not some tech that ain't ready and now been reduced in security. WTF

How do you know its fact? Can you provide some actual proof of this "fact"? Just you saying its fact doesn't make it so. With the extremely low yields and speculation that the iPhone X will be in extremely low availability I would assume that they didn't reduce the accuracy very much, if at all otherwise they would prob have more stock on launch day. Guess we will just have to wait an see on launch day and thru the remainder of the year. Until their is actual proof of something, instead of speculation then PA is accurate in saying "allegedly". I know its hard for some of you to accept that word because you hate Apple, but THAT is the FACTS.

So now because of the reduced accuracy if I were to use Face ID to lock my phone, somebody who looks a lot like me but not quite exactly like me MAY be able to unlock my phone.

Next year on the iPhone X 2. We're so brave that we've actually removed the screen. Available for purchase separately on the Apple store for €500...

That's B.S. Apple. Reduce the accuracy of this revolutionary unlocking feature, after totally eliminating TouchID from the phone as well...wowww! I can't wait to read the comments on this crap, and see the flock, flock to make excuses for it. Glad I got a Note 8.

that phone can wash my car for me but as long as it has touchwiz its going to rot from the inside in a few months- and you paid a$1000 for it.

TouchWiz has been gone for quite some time. Try to keep up.

Bucky, that's a nominee for most stupid comment of the day. Anyone who actually uses a Samsung phone these days, knows how well they keep up after months and months of use.

I have 2 Note 8's and I didn't pay $1000 for either of them.

Probably it's just an excuse, to hide that faceID actually isn't as accurate as they claimed in presentation.

So they're making the feature that failed during their showcase less accurate? Sounds like a good idea.

Exactly ted & also as per Mr. Ive, this technology was(is) 5 years in the making. I mean is he really serious? 5 freaking looooongg years and this is what you have? :D :D :D

Well, it probably is a 5-year development cycle to achieve this, but unfortunately it looks like maybe they're only 3.5-4 years into it.

Based on what? Your word? They aren't even gonna have enough to even make that a possibility.

Probably not. By the time they get up to speed, the XS will be in the works. It'll be the same phone, though, so they can just combine the sales.

They're reducing the accuracy of FaceID, instead of just delaying the release until they have enough iPhone X units ready for a mass launch? Man, Apple truly has changed under Cook. Do you honestly believe Steve Jobs would have allowed the iPhone X to be released with a notch....let alone released with a less accurate FaceID? Jobs was a perfectionist first and foremost. After these past few years, as much as I love Apple....they just don't feel like the same company they were when Jobs was at the helm.

Right on, man. The Apple of today is all about making quick cash, even at the expense of performance and convenience of it's own consumers. Who the heck would want a half-assed and less accurate Face ID just for the sake of getting the iPhone X quickly? Hilarious.

I would still not want this phone because it's a 1st gen device in terms of hardware & software. It already has so many production problems and idk which additional problems it would cause once it's out in people's hands.
