The Xperia Z2 is Sony's successor to the flagship Z1, and the device was first unveiled in February but has just started shipping in time for Easter.
The Xperia Z2 measures in at 8.2mm thick, with a slightly slimmer design and a bigger 5.2in LED display than the 5in Xperia Z1. It comes running the latest Android 4.4 KitKat version.
A key upgrade to the latest flagship is that you can record and display 4K video, thanks to the Xperia Z2's 3840x2160 pixel resolution, four times that of Full HD, which is a feature not seen on previous Sony smartphones.
The device is powered by a quad-core 2.3GHz Qualcomm Snapdragon 801 processor with Krait CPUs and 3GB of RAM, and features a 3,200mAh battery and support for 4G LTE connectivity.
The Xperia Z2 camera is the same as the Xperia Z1 with a 20.7MP rear-facing camera but with the improved 4K shooting capabilities.
Like the Xperia Z1 and the Xperia Z, the Xperia Z2 can be dunked in water for up to 30 minutes at a depth of 1.5 metres - a claim we put to the test in our video - due to its dust-resistant and waterproof IP55 and IP58 certification.
