Android 4.4 is a pretty significant update, one that sees both UX changes and plenty of new features added. A lot has also gone under the hood, but anyone using a stock version of the platform will immediately notice subtle differences in the design, layout, look and feel of the platform.
Icons are bigger, the app tray has been re-designed and Google Now is a lot more influential inside the OS. Android 4.4 is currently only available on Google’s Nexus devices –– specifically, the Nexus 5, Nexus 7 (both versions), Nexus 4 and Nexus 10. Unfortunately there is no support for the Samsung-built Galaxy Nexus S.
Below is everything you need to know about Google’s brand-spanking new iteration of Android complete with update news, features, reviews and tips and tricks. Take a break, have a KitKat, and enjoy…
