According to Sony, the Ultra Z is also the world’s slimmest smartphone (6.5mm) having the largest HD display (6.4-inches) in the market.
Like its older brother, the Xperia Z, the Xperia Z Ultra is also waterproof and dust resistant.
Interestingly, the smartphone can also be submerged to a deeper limit than the Xperia Z — 1.5m (4.9ft) in freshwater for up to half an hour.
Sony is expected to launch the Xperia Z Ultra worldwide from Q3 2013.
