Google on Monday began rolling out Android 7.1.2 beta 2 to developers, which is available for Pixel and Nexus devices.
Droid-Life shared release notes for Pixel devices. The wording is slightly different compared to what Nexus 6P users are seeing:
This update will install a beta version of Android Nougat 7.1.2 (NPG47I) on your Pixel. New features include app shortcuts, image keyboard support, and more. This pre-release version may contain errors and defects that can affect normal functioning of your device. To learn more about the Android Beta Program or opt out, visit www.android.com.beta. Downloading updates over cellular data or metered Wi-Fi networks may lead to additional charges.
Apparently, the new beta adds fingerprint swipe gestures to the Nexus 6P, which has been an oft-requested feature. The same feature came to the Nexus 5X in February.
Beta Program testers with a Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, and Nexus Player will be able to download the new software.
