Google has rolled out the finished version of its Android 8.0 mobile operating system, adding the nickname "Oreo" for good measure. As usual, the roll-out will take some time, with those owning Pixel and Nexus phones likely to be first in line.

With the beta having been launched earlier this year, there's not much we don't know about Android Oreo. You won't find any huge new features here, especially as Google (unlike Apple) updates flagship apps such as Gmail and Google Maps separately to its overall mobile OS.
