OnePlus 6: now with official Pie (in beta form)

Those who use the OnePlus 6 may have become a little impatient for their taste of OOS based on official Pie rather than Developer Preview 3. On the other hand, a lucky few will have been inducted into OnePlus' Closed Beta program in order to test this new firmware. However, this software is now open to all who own the phone - so long as they are willing to migrate to OnePlus' Open Beta stream of updates for the phone.

These Open Beta (OB) releases are early-preview versions of their stock firmware, with potentially new features. The company tests these new features, as well as the overall stability of the new ROM, through the feedback of those users who download and run it on their devices. OB1 for the OnePlus 6 includes advance access to OS changes such as a new Pie-based UI and navigation gestures. OnePlus also includes refreshed Gaming and Do Not Disturb Modes in the OB1. Its users will also be able to test out OOS' newest take on the custom accent color.

Then again, this is an initial beta; therefore, there may be some issues that affect the everyday use of the ROM. In this case, known OB1 bugs include a lack of functional Google Pay; the potential for some apps to malfunction; and the possibility that the device will show up as uncertified in the Google Play Store. Those who choose to test OB1 may also lose their user data in installing the new ROM. These are all things to take into account in considering what is the 'inside track' on software updates for OnePlus device users.
