Sony Xperia Z Ultra

First impressions

 Smartphones are increasingly getting bigger, closing the gap with tablets. In fact, at a point where the smartphone screen crosses the 6-inch, it's difficult to call them smartphones. While not everyone likes to call them 'phablets', they clearly lie in hybrid territory, offering smartphone features in a near tablet form factor.

Sony has also recently forayed into this segment, with its new device, the Xperia Z Ultra, which boasts of a 6.4-inch display. It's certainly not the first device to sport a large screen; we've seen the Samsung Galaxy Mega 6.3 and the Huawei Ascend Mate featuring 6-inch+ displays, but we'd have to say that it's the sleekest out of all of them, at this point in time. The Xperia Z Ultra is super slim with a thickness of just 6.5mm.

We got a chance to play with the Xperia Z Ultra, and feel that it is one the sleekest devices, available. Although it weighs 212 grams, the overall weight to dimensions ratio is optimum and the phone doesn't feel very bulky. Having said that,  it doesn't easily fit the front pockets of your jeans, and you'd need to put it in a bag or hold it all the time. The Xperia Z Ultra follows the same design language that we've seen in the Xperia Z and looks more rectangular as the edges are just subtly rounded

The front of the device is dominated by its 6.4-inch display. The Xperia Z Ultra's screen has a resolution of 1080x1920 pixels and is the first smartphone display that integrates Sony's Triluminos technology, which the company introduced at CES with its Bravia televisions. Sony claims that through the technology the display reproduces a greater range of rich, natural colours to deliver true, natural shades. It won't be wrong to say that the Xperia Z Ultra's screen is the most brightest and vivid display we've ever seen on a device of this size. Unlike the Sony Xperia Z.where we'd observed minor niggles with viewing angles, the Xperia Z Ultra's screen was flawless. Pictures and videos looked natural and colour reproduction was pretty accurate. The big screen and the full-HD resolution makes watching videos a joyful experience. Blacks had the perfect depth and the screen contrast was optimum.

Another interesting feature of the Xperia Z Ultra is its handwriting recognition functionality. The phone's screen is compatible with any pencil and selected stylus or pen with tip diameter over 1mm. We tried using a lead pencil to input text on the phone's screen with the Notes app and found that it recognised our writing with mixed accuracy. It offers word predictions even in the handwriting recognition mode, so this should not be a major problem.
