We think we know how the long-time rumored Sony Yuga will be called – it will be known as the Xperia Z. The information comes from the well-informed Xperia Blog which got it from a guy who’s know to provide credible information at XDA. That source also added that the device will be water- and dust-proof, supporting IP55 and IP57 ratings (similar to the Xperia acro S and Xperia V).
Moreover, we’re hearing that Xperia Z’s 5-inch 1080p screen will come with OptiContrast technology, which was also used on the Xperia V and Xperia Tablet S. This technology provides low reflection due to a special resin layer that absorbs any diffused light delivered from the backlight. As a result, you should get vivid colors, high contrast levels and a real sense of depth.
Finally, we got the size of the Xperia Z – it will measure 139 x 71 x 7.9 mm, making it pretty easy to carry around.
