Part of the Xperia X series, the device was announced to the public on April 16, 2018, featuring a 4K HDR display and a MotionEye™ Dual Camera.

The 5.8 in (150 mm) IPS LCD screen has a pixel density of 765 ppi when rendered in 4K resolution and features Sony's TRILUMINOS display and X-Reality for mobile technology.

The device also has an internal storage of 64 GB and comes in single-SIM and dual-SIM versions, with both featuring LTE Cat.

It also has SteadyShot with Intelligent Auto in addition to the five-axis sensor-shift image stabilization first seen in the Xperia XZ.

When it detects fast-paced movement, the camera automatically captures a maximum of four photos before the shutter button is pressed, and lets the user select the best one afterward.

This is done without any user intervention and is possible due to the same built-in RAM chip on the image sensor used in capturing the 960 fps super slow-motion videos.

Other connectivity options include Bluetooth 5 with aptX and Low Energy, NFC, dual-band Wi-Fi a/b/g/n/ac with 2x2 MIMO antennas, Wi-Fi Direct, MirrorLink, screen casting via Miracast, Google Cast, DLNA, GPS (with A-GPS), GLONASS, BeiDou and Galileo satellite positioning.
