Just when we were begining to come to grips with the Android Marshmallow, Android releases the Android Nougat 7.0 OS.
As is usually the case with Android system updates, the rollout of Android 7.0 should take weeks to complete, so don't panic if your beloved Nexus isn't showing an update notification in the next ten minutes. Devices that are currently running the Developer Preview will be updated too, by the way.
Android 7.0 Nougat brings with it the ability to set multiple locales and languages, 72 new emoji, multi-window functionality, a way to quickly switch to the previous app (by double-tapping the multitasking button), the Vulkan graphics API, a dedicated VR mode, Doze on the Go for even better battery life when you're on the move, custom Quick Settings, direct replies from notifications, bundled notifications, a built-in mobile data saver, file-based encryption, and much more.
