At the start of the month OnePlus released a new beta version of OxygenOS, officially bringing the full version of Android Pie to the OnePlus 6 for the first time. Being a beta it required users to jump through some hoops before they could install it, and wasn't expected to be representative of the inevitable stable release. If you held back for those reasons, you're in luck, because over the weekend OnePlus announced the stable version of OxygenOS 9.0 has begun rolling out.
Here's the official changelog for the stable version, and as you can see it comes with adaptive battery support, which was't mentioned during the beta rollout. Other than that everything seems to be basically the same - albeit without the issues affecting app compatibility and Google certification.
Updated system to Android™ 9.0 Pie™
- Brand new UI for Android Pie
- New adaptive battery support
- New Android Pie gesture navigation
- Updated Android security patch to 2018.9
- Other new features and system improvements
Do Not Disturb mode
- New Do Not Disturb (DND) mode with adjustable settings
New Gaming mode 3.0
- Added text notification mode
- Added notification for 3rd party calls
- Supported accent color customization
OnePlus also revealed that the OxygenOS version numbers will now start corresponding to their Android equivalent for the first time. So this year we have Android 9 and OxygenOS 9, with OxygenOS 10 coming whenever Android 10 arrives, and so on. The company also confirmed that the rollout isn't happening on a regional basis. Initially the update was rolled out to a select number of handsets, and after confirming there are no critical bugs OnePlus will kickstart the wider rollout for other OnePlus 6 devices. My OnePlus 6 has yet to update, so there are definitely still going to be people who have to be patient.
There's no word on when the update will be rolling out to OnePlus 5, 5T, 3, and 3T handsets. In the past OnePlus confirmed all four devices would get the update, with new handsets getting priority. Now that Android Pie is available on the OnePlus 6, it shouldn't be too long before it rolls out to the others. You'll just have to be patient. [OnePlus via Ubergizmo]
