Just over one month after the official release of Android Pie, OnePlus is rolling out its version of the update to the OnePlus 6. OxygenOS 9.0, the company’s fork of Google’s operating system, delivers many of the same improvements as stock Android, including a tweaked interface, gesture navigation, and adaptive battery functionality.

The speed at which OnePlus has rolled out this update is impressive given that many manufacturers can take months to update to the latest version of Android, if they do at all. Less than 15 percent of devices are running last year’s Android Oreo, leaving 2016’s Nougat as the most popular version of the software. Google’s most recent attempt to fix the fragmentation issue is called “Project Treble,” and it could explain OnePlus’ speed in issuing this latest update.

OnePlus is also bringing Pie’s functionality to a broad range of its phones. The company has announced that it will eventually bring the update to 2017’s OnePlus 5 and 5T as well as 2016’s OnePlus 3 and 3T. Yes, that means that the oldest phone to get an Android Pie update so far is a OnePlus device.
