Sony has unwrapped a significantly redesigned flagship smartphone, the Xperia XZ2, in Barcelona this morning, as Mobile World Congress 2018 prepares to open its doors to visitors. 

The device is the first in the world, Sony claims, to feature 4K HDR video recording. 

It also boasts Full HD super-slow motion recording at 960 frames per second, a step up from the 720 quality available on its predecessor, the XZ1. 

However, Sony has for the first time ditched the 3.5" audio jack from its flagship device, opting instead for a USB Type-C audio connection. 

An adapter will be provided in the box though for those who wish to continue using their 3.5" headphones. 

The manufacturer has opted for a completely new "ambient flow" design for the XZ2, with fluid 3D glass front and back and an aluminium frame to prevent twisting. 

The display size has changed too, up 13% from the 5.2" screen on the XZ1 to 5.7" on the XZ2, with an 18:9 aspect ratio. 

The screen itself is a Full HD+ HDR Triluminous display with Gorilla Glass 5 protecting it. 

X-Reality software in the device upscales video with standard dynamic range to HDR. 

Dynamic Vibration technology similar to that found in the Sony Playstation Dual Shock controller has also been intergrated into the XZ2. 

Software scans audio files for vibration cues and a haptic engine inside the device translates those into physical vibration, enabling music and video audio to be felt as well as heard. 

Wireless charging is also introduced to the Xperia premium handset for the first time.

The speakers on the XZ2 are 20% louder than on its predecessor. 

The device is driven by the latest Qualcomm Snapdragon 845 processor and comes with 64GB of ROM and 4GB of RAM. 

Extra storage can be added, however, with a Micro SD card of up 400GB. 

The XZ2 also sees an update in the Xperia’s 3D scanning app, 3D Creator, with selfies now possible using the front facing camera.

The handset runs on the latest version of Android, Oreo, and is IP65/68 rated, making it water resistant and dust proof. 

A smaller compact version of the XZ2 was also unveiled at this morning’s press conference. 

It features a 5" display with the same full HDR features of its larger cousin. 

It also has 4K HDR and full HD slow motion video recording, but unlike the XZ2 it does not offer Dynamic Vibration. 

The Xperia XZ2 will be available in Ireland from April 6 across all major operators, with pricing still to be announced. 

It will be available in liquid black, liquid silver, deep green and ash pink colours.
