It turns out to be phone-specific (?)  Galaxy Note8 problems, but not Galaxy Note9?  I even went to the extent of deleting & reinstalling the H9 Control app on the Note8, with the same non-alphabet results.  [And speaking of Notes … To Self:  In a rush … dumb*** move, and I know better … Always Back Up Your Presets!].

Sorry to hear that…

My experience with my Galaxy S8 is just messing around the keyboard setting and the orientation…Many Android issues I get from uesrs are phone-specific…
