Android 10-based One UI 2.0 update is now making its way to Galaxy Tab S6 owners. It brings forth all the standard One UI 2.0 and Android 10 features, and is bundled with the March 2020 Android security patch. Currently, it is only available in Germany for the LTE variant of Samsung's flagship tablet. A wider rollout should commence in the coming weeks.
