The UI is largely the same, although with some tweaks on top of Android 4.4 Kit Kat. The Z2 will also support “knock” to wake like many of the Nokia Lumia devices we’ve seen in the last 12 months.
There’s high-resolution audio support in line with Sony’s push towards HD Audio at CES, as well as support for capturing 4K video in the camera menus and slow-motion “Timeshift” video capture.
The Z2 also seems to have a big focus on the ability to “throw” content at a larger screen, indicating Miracast compatibility with Sony-branded TVs.
We’ll be on the ground at Mobile World Congress and will bring you all the Sony action from the show.
