OnePlus is rolling out new OxygenOS updates for its three 2020 flagship devices, the OnePlus 8, OnePlus 8 Pro, and OnePlus 8T. As usual, the changelogs are unified but the build numbers are a bit of a mess. Nonetheless, we've put together all the information for you in one place, and we've also collected the OTA download links so you can skip the wait.

The OxygenOS updates rolling out for the OnePlus 8 and 8 Pro carry build number 11.0.4.4 and are based on Android 11. The last OxygenOS stable update for the OnePlus 8 series carried build number 11.0.3.3. Meanwhile, for the OnePlus 8T, OnePlus is rolling out OxygenOS 11.0.7.9 in India and North America and OxygenOS 11.0.7.10 in Europe. The last stable update for the OnePlus 8T had build number 11.0.6.7, 11.0.6.8, or 11.0.6.9 depending on the region. The most notable change introduced in these OxygenOS updates is a bump in the underlying Android Security Patch Level. The updates bring the January 2021 security patches which have already been superseded by the February 2021 security patches.
