Sony Xperia Z2

The talk of Mobile World Congress was the Sony Xperia Z2. It takes the Xperia Z1 - launched only 6 months previously - and refines it. The screen expands to 5.2-inches and it gets itself a 2.3GHz quad-core Qualcomm Snapdragon 801 processor and 3GB of RAM, so it could be one of the fastest phones around.

It's large though, as the previous model was, but it's definitely better. With added software refinement and Android 4.4 KitKat, it's more polished and offers more features than the previous device.

Most of the rumours were true: there are front-facing speakers to boost the sound quality, but also noise cancellation through the supplied headphones. There's 4K video, as well as stabilisation.

The new Sony handset will be available from 10 April, and the phone is on pre-order for £599.
