OnePlus has started rolling out OxygenOS Open Beta 9 for the OnePlus 7 Pro, its 2019 flagship smartphone. The last OxygenOS Open Beta for the phone, Open Beta 8, brought a one-handed mode and December 2019 security patches. This update enhances the one-handed usage for the dialer app and brings the January 2020 security patches. There are also a few other optimizations. For one, the network has been optimized for a better gaming experience. The weather app crashing issue has been fixed, and the Zen Mode 1.5.0 app now supports OnePlus Account login, synchronization of badges and historical data. Finally, the system stability has been improved and general bugs are said to have been fixed.

It's worth noting that OxygenOS Open Beta 9 for the OnePlus 7 Pro as well as other OxygenOS updates were initially delayed because workers were given extended stays to avoid the spread of the 2019 novel coronavirus (Covid-19). Workers across China are now heading back to work, with many working from home as the lockdown in Hubei province continues.

The full change-log of the update is noted below:

OnePlus 7 Pro users running Open Beta 8 should have started getting the OTA for Open Beta 9. Users still on Android 9 must update to Open Beta 5 first as they can't directly upgrade to any newer beta versions after Open Beta 5. OxygenOS stable users can change to the Open Beta update track by following OnePlus' instructions.
