The TrueDepth camera system is also needed for Portrait Mode and Portrait Lighting options when taking selfies with the front-facing camera. Specifically, problems are still arising with the iPhone X's dot projector, the component responsible for illuminating a user's face with 30,000 infrared dots to create a depth map of a user's face.
The dot projector makes up part of the transmitting module, dubbed "Romeo", of iPhone X's new facial recognition function that allows users to unlock phones and make payments, according to the executive. The Home Button has been removed from the iPhone X, with Apple adding a new Tap to Wake feature which works alongside Raise to Wake.
Yuanti Investment Consulting analyst Jeff Pu predicts that the iPhone X will soon enter mass production and units will start shipping out of China in the third week of this month. However, the analyst has cut his forecast of 2017 iPhone X production by 10% to 36 million units.
Earlier this week, Redditor turnaround_ posted an image of workers painting a new iPhone X ad in Toronto, which some might say is a "lost art".
Apple will start taking pre-orders for the iPhone X on October 27 and will launch the device November 3. Of course, it goes without saying that supply will likely be extremely limited at launch, with some analysts opining that many interested buyers may not get their hands on the iPhone X until 2018.
Besides the Face ID, the iPhone X has other features the recently released iPhone 8 and iPhone 8 Plus don't have. The iPhone X, like the iPhone 8 and 8 Plus, features wireless charging capabilities, is waterproof and supports augmented reality apps.
