The Sony Xperia Z Ultra is finally official and it boasts a Qualcomm Snapdragon 800 chipset, a 6.4-inch 1080p display and water-resistant capabilities, among others.

After lots of rumors, leaks, and some more rumors and leaks, Sony officially unveiled its brand new super-sized smartphone, an Xperia Z Ultra phablet that closely resembles the design of its flagship Xperia Z smartphone.

"The Xperia Z Ultra is the most exciting revolution in large-screen smartphone entertainment devices with both the slimmest and largest Full HD smartphone display in the world that is second to none," boasts Calum MacDougall, Director of Xperia Marketing at Sony Mobile Communications, in the press release. "We're already bringing the best of Sony technology and design across a range of premium smartphones and tablets, and now we are bringing this same premium offering to the large-screen smartphone segment, setting a new standard for others to follow."

Except for the camera, Sony boosted all specs over the currently flagship smartphone, packing the phablet with a massive 6.44-inch Full HD display, a quad-core Snapdragon 800 processor clocked at 2.2GHz, a water- and dust-resistant exterior and an ultra-thin body.

The screen on this device is quite impressive. Sony calls it Triluminous Display and that 1080p resolution packs a pixel density of 344 pixels-per-inch (ppi). Sony also skipped the usual Mobile BRAVIA technology in favor of its OptiContrast and X-Reality tech, which is definitely a step up.

The processor on the Xperia Z Ultra is considered "the world's fastest," while the graphics come courtesy of the Adreno 330 GPU. In terms of operating system the latest Android 4.2.2 Jelly Bean will be running the show. The device also sports an 8-megapixel Exmor-RS sensor camera that can record 1080p video and supports HDR. A 2-megapixel front-facing camera can shoot 1080p at 30 frames-per-second (fps). Sony Xperia Z Ultra owners will also be able to use a pencil, pen or a capacitive stylus on their phablet.

The water-resistant device comes with 16GB of internal storage capacity, but only 11GB of those are actually available to users. A micro SD card slot, meanwhile, allows for additional memory.

The Sony Xperia Z Ultra has IP55 and IP58 ratings, which means the device is resistant to dust as well as waterproof. According to the company, users will also be able to shoot Full HD video underwater.

The new Sony Xperia Z Ultra phablet will launch globally starting in the third quarter of this year, but exact availability will vary by market. Sony gives no details about pricing so far but more information should become available closer to launch. Meanwhile, check out this video to see the phablet in action.
