After a time in beta, Google is finally rolling out Android 7.1.2 for Nexus and Pixel devices. Just few minutes ago, Google rolled April Security patch for both the pixel and Nexus devices lineup.
Now, Google appears to be rolling Android 7.1.2 as they appeared to have posted the Android 7.1.2 images. These are the devices for which they have posted the images: the Pixel and Pixel XL (N2G47E, N2G47J), Pixel C (N2G47D), Nexus 6P (N2G47H), Nexus 5X (N2G47F), and Nexus Player (N2G47H).
Android 7.1.2 brings fingerprint gestures that were once available for the Pixel devices only, but are now available for the Nexus 5X and Nexus 6P, a new launcher for the Pixel C tablet, plus a new navigation bar and revamped multitasking screen to take better advantage of the larger screen.
