Samsung is seeding the much-awaited stable version of the One UI 3.0 software, which is based on Android 11, for the Galaxy Z Fold2. Users in Germany and South Korea are already receiving the latest version of the OS.
Along with the big One UI 3.0 upgrade, the package contains Google's January 2021 security patch. Anyway, you will be getting all the usual Android 11 features like the improved notification area and chat bubbles.
As usual Samsung only rolls out the update in a handful of markets initially and if no issues are discovered it proceeds with the global rollout.
