The Sony Xperia Z Ultra Triluminous screen has 1080p resolution, giving it a nicely sounding 344ppi pixel density. It uses Sony's OptiContrast and X-Reality tech, which it's the successor of the Mobile BRAVIA tech. Sony is boasting that the 6.4" display gives users 60% more surface to work with compared to other phones (5" phones presumably).
You can use a regular pencil or pen as a stylus as well as a capacitive stylus.
There's a powerful Adreno 330 GPU to push all the pixels to the screen too, a part of the new Snapdragon 800 chipset, which also packs a quad-core Krait 400 processor clocked at 2.2GHz. That makes the Sony Xperia Z Ultra the first device to go official with the 800 chipset and it will surely be quite the benchmark champion when it comes up.

The new chipset runs Android 4.2.2 with a revamped Sony software to make good use of both the extra available power and screen real estate.
The camera on the back of the Sony Xperia Z Ultra phablet has an 8MP Exmor-RS sensor that can record 1080p video and supports HDR for both stills and movies.
The Sony Z Ultra uses the same OmniBalance design as the Xperia Z, including the tempered glass back, but adds a metal frame along the sides and at 6.5mm it's even slimmer than the hot-looking smartphone. It's water-resistant too with a IP58 certification, same as the Xperia ZR. Unlike the IP57 of the Xperia Z, this certification allows the Xperia Z Ultra to dive deeper than 1m and stay there for longer.





The Ultra packs 4G LTE connectivity, HD Voice along with NFC. There's also Sony's proprietary WALKMAN player with ClearAudio+ and xLOUD enhancements.
Sony is advertising it as the world's slimmest 1080p phone - it measures only 6.5mm thick. That screen size and 3,000 mAh battery come at a price though, 212g of weight in this case.
The Sony Xperia Z Ultra is expected to launch in Q3 this year in three color versions - white, black and purple.
