Samsung Galaxy S9+ Stuck with Android v8.0 - how to upgrade the OS?
I have a Samsung Galaxy S9+.
The phone is currently operatinng on Android v8.0.0.
When I try the "Upgrade Software menu" (Settings --> Software Upgrade --> Check for Updates --> OK), it says "Software is up to date".
I have plenty of memory available. Battery is fully charged. I'm on a strong WIFI.
However, I know the Android OS is currently at v11.
How do I "force" an OS upgrade?
