There is constantly a message to select keyboard on dropdown menu. I have chosen many times the keyboard (I bought one) but the notification wont go away....Thoughts?
I don't have the Tab S3 yet but if it works as it does on my S6, as long as you've got more than one keyboard installed, you will get the notification. The only way to get rid of it would be to disable the built-in keyboard (using third party apps). Try at your own risk.
