CES provided a chance for us to get our hands on two of the latest smartphones. Interestingly, Sony's Xperia Z, ZTE's Grand S and the Huawei Ascend D2 are all built around 5", 1920 x 1080 pixel screens and feature 13MP cameras. All run Android 4.1 (Jelly Bean) and yet, despite the spec similarities, there are still differences - in the user experience as well as the processors used. We had the opportunity to use all these phones, to see how they behave - find out what we thought.

Sony identifies its camera sensor as one of its own Exmor RS chips - one of the 'Stacked CMOS' designs that it announced in January 2012 (between then and now Sony announced it was dropping the RGBW design).
