This is rather disappointing. It's tragic to upgrade a device and lose functionality like this. There is nothing the new note should "not be able to do" that a year old device can.
It seems like a simple decision to include on approved devices list. Versus any technical limitation around why new devices can't run Linux.
I'm looking for a dislike button. I upgraded to the note10+ from the note 8. This is one of the features I was excited about. Samsung! We need this updated to support all of the note 10 variants!
