has made the first Open Beta build of OxygenOS based on Android 9 Pie available to the OnePlus 6. OnePlus had previously been testing the beta with a closed group. Now, anyone with a OnePlus 6 and the desire to check out Pie can install the beta platform on their device. OnePlus says the beta introduces a brand new user interface for Android 9 based on Pie's gesture navigation. The beta offers system improvements, more customization features, and a refreshed Do Not Disturb mode. Other features include a new Gaming Mode, improved text notifications, and third-party call notifications. OnePlus warns there are several known issues with the build. For example, Google Pay is not working, and the Google Play Store may display a "Device is not Certified by Google" notification when users attempt to download apps. Devices running the beta may also suffer from instability. Instructions for downloading and installing Android 9 Pie on the OnePlus 6 are available from OnePlus' web site.
