This breakthrough technology includes X-Reality™ for mobile – Sony’s intelligent display technology which analyses each image to optimise colours, sharpness and contrast for vivid image quality. The super resolution feature reproduces lacking pixels resulting in sharp videos while the large Full HD display has been optimised to experience at least 60%**** more of the screen than most smartphones.

    Hi! Joe.Sorry for my late comment.I like Sony very much especially Skin,theme,screen and Camera and camera user interface.Though I don’t have any xperia smartphone at the moment but I’m considering one from you guys.Sony I like the way you invade things and how hard you really push it hard to make sure your consumers get best out of you.I have been following sony since 2012 and I realized one thing and which is killing you guys,you have not focus in Africa especially Kenya,I don’t know why,but you should consider since Kenya is one of the African country very aggressive to smartphone world.

    I been using the Sony Xperia Z Ultra for some time not bad to use as I like the visual and the sound of the phone.
    Hardly use the camera to take photo in the night so I feel this is a good phone so far better than Samsung phone which always have software problem.
