We first learned about the forthcoming release of Android N way back in March before it even had a name. In June, we learned that the OS would officially be called Android 7.0 Nougat. Today, it finally begins rolling out to Nexus devices with an over-the-air update.
Owners of Nexus devices such as the Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, Nexus Player, and Pixel C should start receiving prompts to update their operating system throughout the day. Any devices enrolled in the Android Beta Program will also receive the update. As with other mass updates, it could take longer for some users to receive the update than others.
