All iPhone Xs models -- which Apple styles as both iPhone Xs and the uppercase iPhone XS -- have a 3D-touch equipped 5.8" (diagonal) OLED HDR "Super Retina" display (2436x1125, 458 ppi, 1 million:1 contrast ratio) that occupies nearly the entire front of the device. It has three cameras. On the front -- tucked in the "notch" -- is a "TrueDepth" camera that in addition to supporting "Advanced Face ID" identification functionality, takes 7 megapixel photos, shoots 1080p video, and has software support for Portrait mode, Portrait lighting, and more. The two rear cameras, one wide angle (f/1.8 aperture) and one telephoto (f/2.4 aperture), both have 12 megapixel sensors, support optical image stabilization, and shoot 4K photos and video. With a combination of hardware and software functionality, the rear cameras offer "advanced depth segmentation," Smart HDR, improved bokeh quality, and dynamic retroactively adjustable depth of field.
