Android 6.0.1 is official. It isn’t quite a huge update in terms of features. You can expect a new set of emoticons, a security update and a few other modifications.
As expected, Nexus devices will get it first – Nexus 5, Nexus 5X, Nexus 6, Nexus 6P, Nexus 7 (2013), Nexus 9, and Nexus Player. After that, it is anyone’s game. So far, there is no evidence that Google’s Android One devices are given any priority in terms of software updates. Till now, Marshmallow has remained elusive to them.
Factory images are already available for Android 6.0.1, if you want to update your devices the hard way.
