Should you be anxious about the iPhone X's facial recognition?

But there is a hidden gem the iPhone X offers that no other Apple or Samsung flagship will provide.

Apple launched three new iPhone models: the iPhone 8, iPhone 8Plus and iPhone X at the Steve Jobs Theatre at Apple's newly-built campus, Apple Park on Tuesday.

The iPhone 8 sports a 4.7-inch widescreen LCD IPS Retina HD display with a 1,334 x 750 resolution and 326 PPI pixel density while the larger 8 Plus features a 5.5-inch screen panel with a 1,920 x 1,080 resolution and 401 PPI pixel density.

It is known that the Touch ID used in iPhone X predecessors, can remember up to five fingerprints.

"People were handling the device for stage demo ahead of time", says a rep, "and didn't realize Face ID was trying to authenticate their face".

However, the demonstration of its facial recognition feature, named Face ID, went awry.

The technology works via an infrared system that Apple is calling TrueDepth, which projects a grid of 30,000 invisible light dots onto the user's face, and then further refines the scan as the user tilts and turns their head. Wired published a deep dive into the much documented problems with facial recognition technologies to date.

After the gaffe, media reports claimed that Face ID failed.

The iPhone X will have Apple's latest processor, the A11 Bionic with an integrated Neural Engine for face recognition, which now has six cores - up from last year's A10 with four cores. But the feature failed, bumping Federighi to an old-fashioned passcode entry screen and forcing him to switch to a backup phone.

Supposedly, the odds of tricking the Face ID software are one in a million - in terms of someone's face coincidentally being a lot like yours - versus one in 50,000 when it comes to tricking Apple's Touch ID - though New York Mag points out that neither is as secure as a regular old password. When it failed to recognize them, it defaulted to the passcode after a set number of unsuccessful attempts, which in Face ID's case is reported to be just two.
