Performance and software
The Sony Xperia Z2 is powered by a quad-core 2.3GHz Qualcomm Snapdragon 801 processor with 3GB of RAM, meaning it is quite the powerhouse. The chip is just as impressive in the real world as it is on paper, and we found the device very nippy, with no lag whatsoever, even when playing and recording 4K video.
As with previous Xperia Z devices, there's LTE support onboard, and the handset arrives with 16GB of internal storage that can be expanded by another 64GB with a microSD card.
As for software, the Xperia Z1 Compact runs Google's latest Android 4.4 KitKat mobile operating system right out of the box. However, Sony has skinned Android with its own custom user interface (UI). While we've never been huge fans of Sony's custom UI, finding it overbearing compared to a vanilla Android user interface, the firm's apps are a bonus. The Xperia Z2 arrives loaded with Sony's Walkman and Playstation companion apps as seen on the Xperia Z1, as well as many new camera features and built-in noise cancellation technology to help block out background sounds while listening to music.
Perhaps the most impressive feature of the Xperia Z2 is its rear-facing camera, which not only features the same 20.7MP sensor as seen in its predecessor, but introduces 4K video recording for the first time with a resolution of 3840x2160 pixels, four times that of HD.
We gave it a quick go on the MWC show floor, and we're pleased to report that image quality is as you'd expect from a 4K camera, with video recording being super smooth due to Sony's Steadyshot technology that acts as a real-time image stabiliser. Image quality looked better than we've seen on a smartphone before.
Still images taken with the 20.7MP camera were just as impressive as seen on the Xperia Z1, appearing crisp, clear and full of natural colour even under the glaring lights of the MWC tradeshow floor.
The Sony Xperia Z2 also features a 2.2MP camera on its front that's capable of shooting HD 1080p video for all your selfie needs.
Connectivity and battery
The Xperia Z2 has a 3,200mAh battery with a claimed talktime of 13 hours. We obviously didn't have the time to test this during our quick hands-on review, but we'll be sure to test the battery fully when we do a full review of the device.
Though we were very impressed with our first hands-on with the Sony Xperia Z2 overall, the handset's success likely will depend partly on its price, which Sony has yet to reveal. It will launch the Xperia Z2 globally sometime in March.

When this review first went live it said the Xperia Z2 had a 4K display. After confirming with Sony that it infact has a 1080p display, we have updated the article. Sorry for any confusion.
