As rumoured, Sony has unveiled its flagship Android powered smartphone, Xperia Z, at the CES 2013 event. The Japanese electronics company has promised that the handset will hit the shelves globally sometime in the first quarter of this year.
Sony Xperia Z, as expected, comes with 5in full HD display, which Sony termed as 'Reality display,' powered by second generation Mobile Bravia Engine for brightness and clear viewing. The device offers 4G LTE network connectivity. It also features several applications including the Walkman, Album, Movies app and one-touch functions. The device is said to be water and dust resistant. Sony claims the handset offers water-resistance to a depth of one meter for up to 30 minutes.
Here is how Sony Xperia Z stacks up against Google's newly released Nexus 4
Xperia Z vs Nexus 4: Display
The Xperia Z features a 5in full 'HD Reality display,' which is powered by Mobile Bravia Engine 2. The resolution of the HD display measures 1080 x 1920pixels with a pixel density of 443 pixels per inch (ppi).
Sony boasts that the Reality display of Xperia Z provides 'incredibly crisp pictures and no jagged edges.' The Reality display of Xperia Z carries higher pixel density, comparatively more than the pixel density of the Retina display of Apple's iPhone 5, to offer clear viewing experience. Moreover, the second generation Mobile Bravia Engine, according to Sony, delivers better viewing and is able to analyse concept type and adjust image accordingly.
The Nexus 4, in contrast, features a 4.7in True HD IPS Plus display with resolution measuring 768 x 1280pixels and pixel density reasonably less than the Xperia Z, at 320 ppi. The display of Nexus 4 is covered by scratch-resistant Corning Gorilla Glass 2.
The HD display of Nexus 4 is supported by a unique screen technology called 'Zerogap Touch technology' to offer clear viewing. The aforementioned technology made its debut through LG's flagship smartphone, Optimus G.
The primary difference is while other touch screen features either ITO film or a glass sensor, the Zerogap Touch has an ITO sensor film printed on the glass, removing the air gap trapped between two elements. This helps in delivering better touch sensitivity while offering an immersive and rear-touch sensing experience. This technology also reduces the thickness of the display offering a slim design as well as sharp viewing, notes Digital Trends.
Xperia Z vs Nexus 4: Dimensions
In terms of physical dimension, the Xperia Z is bigger in size compared to the Nexus 4. On the other hand, the Nexus 4, with its 9.1mm thickness, is slightly thicker than Sony's new handset. As far as weight is concerned, the Xperia Z is just seven gram heavier than the Nexus 4, at 146g.
Xperia Z: 139 x 71 x 7.9mm
Nexus 4: 133.9 x 68.7 x 9.1mm
Xperia Z vs Nexus 4: Operating System
The Xperia Z will first launch with Android 4.1 (Jelly Bean). But Sony promises that the device will be upgraded to the latest Android 4.2 (Jelly Bean) shortly after the launch.
The Nexus 4 is Google's first smartphone to adopt Android 4.2, which was introduced alongside the announcement of the new Nexus devices.
