IPhone X

iPhone X (Roman numeral "X" pronounced "ten")[9][10] is a smartphone designed, developed, and marketed by Apple Inc. It was the eleventh generation of the iPhone. It was announced on September 12, 2017, alongside the iPhone 8 and iPhone 8 Plus, at the Steve Jobs Theater in the Apple Park campus. The phone was released on November 3, 2017, marking the iPhone series' tenth anniversary.

The iPhone X is intended to showcase what Apple considers technology of the future, specifically adopting OLED screen technology for the first time in iPhone history, as well as using a glass and stainless-steel form factor, offering wireless charging, and removing the home button in favor of introducing a new bezel-less design, almost removing all the bezels in the smartphone and not having a "chin", unlike many Android phones. It also released a new type of password authentication called Face ID. Face ID is a new authentication method using advanced technologies to scan the user's face to unlock the device, as well as for the use of animated emojis called Animoji. The new, nearly bezel-less form factor marks a significant change to the iPhone user interaction, involving swipe-based gestures to navigate around the operating system rather than the typical home button used in every previous iteration of the iPhone lineup. At the time of its November 2017 launch, its price tag of US$999 also made it the most expensive iPhone ever, with even higher prices internationally due to additional local sales and import taxes.

The iPhone X received mixed reviews. Its display and build quality were universally praised, and the camera also scored positively on tests. The phone received particularly polarized reception due to the sensor housing "notch" at the top of the screen and the introduction of an all-new authentication method. The notch was heavily mocked by users on social media, although app developers responded either neutrally or positively to the changes it brought to the user experience in their apps and games. Reviewers had mixed reactions, with some condemning it and others acknowledging it as unusual in the first moments of use before getting accustomed to its presence. Face ID facial recognition was praised for its simple setup, but criticized for requiring direct eyes on the screen, though that option can be disabled within the system preferences.

Along with the iPhone 6s, its Plus variant, and the iPhone SE, the iPhone X was discontinued on September 12, 2018 following the announcement of the new iPhone XS, iPhone XS Max, and iPhone XR devices. As a result, with a shelf life of just over 10 months, the iPhone X had the shortest ever tenure as the flagship device in the history of the iPhone.

On November 22, 2018, Apple has reportedly resumed production of the iPhone X due to weak sales of its successors. The iPhone X remains discontinued[11], but as of February 2019, Apple started selling refurbished models for $769.[12][13]
