Sony today released Android 4.4 KitKat for some of its Xperia line of devices, including the Z, ZL, ZR, and Tablet Z. The update is rolling out based on location, as well as by carrier, so it may still be some time before you see the update notification on your particular device.
The release includes the performance optimizations and tweaks found in stock Android 4.4, but also carries various Sony enhancements.
The most noticeable change will be the user interface:
If you’ve got a Sony PlayStation 4, you might recognize our new user interface – we’ve added the same sleek launch animation and live wallpaper across the lock and home screens. You’ll also spot a revamped Status Bar and Quick Settings… now more intuitive and customisable (also with a fresh new look)… cleaned up to ensure you only get the notifications you really need
The update also brings these devices closer to parity with more recent releases, as it includes features like the battery Stamina mode, and brings integration with the Sony Entertainment Network.
The KitKat update also makes these device compatible with Sony’s Xperia Themes and SmartWear Experiences, which includes both the Lifelog app and the Smartband.
