Sony Xperia Z review
Android 4.1 (JellyBean), 5.0in 1,920x1,080 display
The Xperia Z was Sony's flagship phone for 2013, and continued the screen size and resolution arms race with its 5in, 1,920x1,080 display, which compares well to contemporary rivals such as the Full HD-equipped HTC One. It also has all the specifications you would expect from a high-end smartphone, including a quad-core 1.5GHz processor and a camera with a huge 13-megapixel sensor.
Sony is continuing to support last year's most powerful phones and tablets with promised updates to the latest Android 4.4 Kit Kat operating system. The Kit Kat update for the Xperia Z is currently being tested, following the roll-out of Android 4.3 Jelly Bean directly from Sony and via mobile networks across the world in the few months since late December 2013. The Jelly Bean update includes an extra bit of gloss to Sony's own user interface, too, as well as upgrading users to the Swiftkey soft keyboard. Meanwhile, Android 4.4 promises to bring even more features and greater power efficiently to this fantastic phone when the update lands in coming months.
The display's Full HD resolution is the same as that of the HTC One, but the slightly larger screen size should make text more legible at this resolution. We found we could view web pages in desktop mode and still read all the page's text easily without zooming in. This is a trick that the HTC One also pulls off, but we found the Xperia Z's extra 1/3 inch screen size made reading more comfortable.
Browsing desktop web pages without zooming in is possible on the 5in 1,920x1,080 display
