OnePlus 3 and 3T recently received Android 8.0 Oreo update with the official Oxygen OS Open Beta 25/16 respectively. The update brings several Android Oreo goodies and features to the stock Oxygen OS firmware. This includes Picture-in-Picture, notification categories, etc. The update looks great and the devices are ready for upgrade. The update also comes with September 2017 security patch level.
