Android P is now available in a first Developer Preview! It’s currently available to the Pixel, Pixel XL, Pixel 2, and Pixel 2 XL.
This is the first Android P build and is labeled as an “alpha” release. It’s for developers here, rather than you and I with our daily phones. In other words, you probably shouldn’t flash this as there could be plenty of stuff that is broken.
This is not a beta, so this isn’t available in the Android Beta Program.
