Google released the latest developer preview of its Android Oreo. The Android Beta Program is available for users to test. The Version 8.1 will be released in December.
Developers can download and install the system images with an unlocked boot loader. The Beta Program issues these updates over the air, although the developer preview supports the Nexus 5X, Nexus 6P, Pixel C, Pixel, Pixel XL, Pixel 2, and Pixel 2 XL.
