The OxygenOS 10.3.11 also brings improvements to system stability and fixes some known issues which are not detailed in the changelog. The update is still based on Android 10. As usual, the latest update for OnePlus 6 and 6T is rolling out in a staged fashion, which means that a small percentage of total users will initially receive the update. After no major/critical bugs get confirmed, the company plans for a broader rollout.
