Android’s next big update, Android O, was unveiled at Google I/O this year and reports suggest that the new version of the OS may come to Pixel phones in August. A source told Android Police's managing editor, David Ruddock about incoming update, who tweeted, “The official OTA to Android O for Pixel will likely drop in the first week or two of August. A bit earlier than Nexuses / Nougat last year.”

If this is true, Pixel users will be able to use the new Android O OS, a few months ahead of the launch of the next pixel. Although, it won't be the first time Google is doing so. Last year, Android Nougat was unveiled and made available for Nexus devices prior to the Pixel and Pixel XL launch.
However, Google has a bigger concern to face, which is the high fragmentation rate between its various OS versions. Latest reports suggest that Android Nougat, which was announced last year, has less than 10 percent of the Android market share. In contrast, Apple recently cited that the latest version of iOS is running on more than 85% of Apple devices.
To solve this, Google has announced a “Project Treble” which will essentially try to bypass the UI OEMs usually put on their devices and the phone as Google intended. Although, we are yet to see it implemented.
As for Android O, there is a beta build of the OS available for Pixel and Nexus users and we know that the new version doesn't look completely different. Aside from some visual and underlying security changes, the latest build of the OS will bring battery improvements, and better background app management. There are some changes on how the phone receives and displays notifications. A wider colour gamut and LDAC codec will also be supported.
