Google today released the second developer preview of Android 8.1 Oreo for testing before an initial release to the public likely sometime next month. This comes after the first build of the software update was released back in October.
During that time, Google publicly confirmed that the Pixel Visual Core, a dedicated processing unit for controlling camera and HDR-related operations for both first-party and third-party camera apps, would be enabled in DP2 of Android 8.1. We can verify this is true as it says so right here.
Additionally, Android 8.1 Oreo will bring the new Neural Networks API (NNAPI) which allows for on-device machine learning operations. There’s also improvements to the way notification sounds are played and tweaks made for low-RAM devices, AutoFill, fingerprints, and wallpaper apps.
If you own a Pixel 2, Pixel 2 XL, Pixel, Pixel XL, Nexus 6P, Nexus 5X, or Pixel C tablet, you can test drive Android 8.1 Oreo by flashing one of these images. If you’re enrolled in the Android Beta Program, expect an OTA update soon. We’ll let you know if we spot any additional changes in this build.
