Android 8.1 will be rolled out to users next month after Google unveiled its final preview build.
While this isn't a mammoth update, it promises some notable improvements. In particular, it'll provide support for the Google Pixel 2 smartphone's Visual Core.
At launch, Google explained that it had integrated a new imaging chip into the handset. However, it didn't have the software means to activate it at the time.
Now, thanks to the new preview build, developers can begin testing the Visual Core. The feature will enable different camera apps to access Google's HDR+ technology quickly.
Visual Core is the first processor designed by Google for a consumer product. It is intended to speed-up camera operations for users.
Writing on the Android Developers Blog, vice president of engineering Dave Burke said: "For Pixel 2 users, the Android 8.1 update on these devices enables Pixel Visual Core through a new developer option.
"Once enabled, apps using Android Camera API can capture HDR+ shots through Pixel Visual Core."
Overall, Android 8.1 will add "targeted" enhancements to the Android Oreo platform. There are optimisations for Android Go (which covers devices with 1GB or less of memory) and a new Neural Networks API to improve on--device machine intelligence.
"We've also included a few smaller enhancements to Oreo in response to user and developer feedback," added Burke.
"If you have a device enrolled in the Android Beta Program, you'll receive the update over the next few days. If you haven't enrolled yet, just visit the Android Beta site to enroll and get the update.
"At the official release in December we'll bring Android 8.1 to all supported Pixel and Nexus devices worldwide - including Pixel 2 and Pixel 2 XL, Pixel, Pixel XL, Pixel C, Nexus 5X, and Nexus 6P. Watch for announcements soon."
