Nearly two months after the release of the first build, Google is now offering Android 7.1.2 Nougat beta 2 to those enrolled in the Android Beta Program. The update is available to all supported devices, including the Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, and Nexus Player. It's good news for owners of the 6X, as the original beta was delayed by almost a month for that device.
Right now, the update is only available over-the-air (OTA), as factory images aren't yet available. In fact, Google hasn't published its usual post on the Android Developers blog; instead, there's only a short note on Google+ that build NPG47I is now available.
While Android 7.1.2 Nougat is rumored to be launched in two weeks on April 3, it's only a maintenance update, meaning that new features will be minimal. The only real new feature that's been discovered is fingerprint gestures on the Nexus 5X.
Also, this update notably ends support for the Nexus 6 and 9. The two devices will continue to receive security updates for the time being, but they won't get anymore Android updates going forward.
When the factory images are made available, you'll be able to find them here.
