Google says Android O Developer Preview 3 this latest preview version, which has the build number of OPP3.170518.006, is meant for early adopters and is available for daily use, development, and compatibility testing. Do keep in mind that you’ll still likely run into a number of bugs and performance issues, such as inconsistent battery life and app force closes.
This release has the final APIs for Android O as well as the official SDK developer tools. The image downloads for the Android O Developer Preview 3 release are below:
Google Pixel C
Google Pixel XL
Keep in mind that if you do decide to flash your device with these factory images, you won’t automatically get future Android O beta or final releases via OTA updates.
Google dropped the second Android O developer preview on the first day of I/O last month, but here we are just a few weeks later and Dev Preview 3 is available. The full system images are available for immediate flashing on supported devices, and beta program devices will probably be updated soon. Importantly, this update should include the final APIs for Android O.
