Updated my S10+ to Android 10 yesterday. I like it overall but one thing I noticed is the new "show keyboard button" setting. I use a non-stock Keyboard and the keyboard button that shows on the navigation bar is huge and white. I don't need this bar or button, I never switch between keyboards. I wouldn't mind much if it were black but being white it stands out a lot. The setting, however, is disabled, so I can't turn it off. Anyone know how I can then this bar off?
I found out how to do it. Go to settings->Display->Navigation bar and turn off "Show button to hide keyboard". This setting only appears here if you have "Full screen gestures" turned on.
