Install Oxygen OS 9.0 based on Android Pie on OnePlus 6

It’s been about a month since Android 9.0 Pie was first released for the Google Pixel devices. In the Android world, that isn’t very long when it comes to Android updates. So the fact that the OnePlus 6 has become only the second non-Google device to receive an official Android Pie update is exciting, especially for OnePlus 6 owners. The company had been testing out Android Pie on the device for quite some time. Oxygen OS Open Beta was soon rolled out after the official Android Pie release. And now you can install the official Android Pie based Oxygen OS 9.0 on OnePlus 6.

If you take note of the OS update version numbers, you might be surprised to see Oxygen OS 9.0 come out directly after Oxygen OS 5.1.3. OnePlus has changed its naming convention so as to match the Oxygen OS number to the Android version number in order to keep things simple. Huawei did something similar a year ago jumping from EMUI 5 to EMUI 8. Other than that, the official Oxygen OS 9.0 is not very different from the Oxygen OS Open Beta 3. The only remaining bugs which were the SafeNet failure and Play Store device certification have all been fixed.

Lucky users may have already received an OTA update but it’s possible some of you haven’t yet. The OTA rollouts happen in phases so as to not overload the servers. But you can still manually download and install the updates using the links provided below. We’ve also cooked up a guide on how to install the downloaded firmware file in case you’re new to this.

    • Brand new UI for Android Pie

  • Before you install the update, make sure to take a full backup of your device. While nothing should go wrong, you can never be sure. It is therefore always a good idea to backup your data before proceeding with any software installation or upgrades.
