Samsung note 8, latest Android
As of my last update, the Samsung Galaxy Note 8 originally launched with Android 7.1 Nougat and received updates to Android 9.0 Pie. Officially, it has not been updated to newer versions of Android beyond that.
However, if you are looking for the latest Android version available for the Note 8, it would be Android 9.0 Pie. For users wanting newer features, there may be custom ROMs available from third-party developers, but these can come with risks and may void warranties or have compatibility issues.
For the most up-to-date information on software updates, it's always a good idea to check the settings app on your device or visit Samsung's official website.
