Sony has announced a waterproof Android Smartphone with a 6.4in display. The firm is headfirst the Xperia Z Ultra as being the slimmest large-screened handset on the marketplace. It can also allow sketches or comments written using a standard pencil or metal-tipped pen in addition to an elective stylus. Sony already offers a 5in handset of its own, the unique Xperia Z, which it unveiled in January.
The firm supposed it intends for the device to face Samsung's dominance of the jumbo-sized handset sector. According to a study by consultants Transparency Market Research, Samsung accounted for 70% of the overall "super phone and phablet" market in 2012 thanks to the popularity of models with the Galaxy S3 and Galaxy Note 2.
