The update brings a new interface, Android Pie's gesture navigation, and adaptive battery life, which uses on-device machine learning to predict which apps you're likely to use and leave them open in memory, while closing those that you're unlikely to use for a while, thereby extending life.
The Android Pie update also includes a new do not disturb mode with adjustable settings, accent color customization and changes to the Gaming Mode, such as the addition of notifications for third-party calls.
Those are the highlights, but OnePlus says the update also includes other new features and system improvements, as well as the latest Android security patch.
A gradual rollout
If you don't see the OTA update (which will be called OxygenOS 9.0) on your OnePlus 6 yet, don’t panic. It's being rolled out in stages, with a limited number of users getting it today (September 21) and a wider rollout in a few days.
The initial rollout isn't region-based, it's luck of the draw as to whether you get it now or later.
