I had a Samsung engineer connect to my phone to try and fix this, and he thought it was because I didn't have a lock screen of any kind...so here is my problem, because adding a lock screen doesn't fix the real issue.
Every time I get a text, my display comes on. When I didn't have the lock screen, and the phone was in my pocket, there was a pretty good chance that it butt-dialed someone.
What I want is to not have the display come on at all but still have the text notification beep.
Does anyone know how to do it?
I got it working.
