This year was going to be special when it came to Android major update when the main 7.0 was published plus what would be three minor updates to add a set of four in total. Those three minor ones would bring some extra features plus a series of optimizations to get Nougat ready for the next major version of Android.
Today Google has started with the Android 7.1.2 beta rollout Nougat for various Nexus and Pixel devices including the Pixel, Pixel XL, Nexus 5X, Nexus Player and Pixel C devices. The Nexus 6P will also have this new minor version, although it will be a matter of days when you can access it.
Those who they stay out of the update are the Nexus 6 and Nexus 9, so they will stay with Android 7.1.1. as the final version. This was expected, since Google confirmed it in its day that there would be no guarantee of Android updates for these devices after October 2016. Of course, both devices will have the security patches for a whole year.
Android 7.1.2 beta update brings with it optimizations for the system including a number of bug fixes and optimizations, while incorporating a series of improvements for operators and users, according to Google itself, since 7.1.2 is a firmware that increases the performance of the device in terms general.
Android 7.1.2 is currently available for the Pixel, Pixel XL, Nexus Player, and Picel C on the developer website from Android. It can also be obtained through Android Beta Program, which is the easiest way to get it. The final version of Android 7.1.2 It will be available for supported devices in a couple of months. Some updates that already arrive in 7.0 to the rest of the devices.
