I was seriously considering boxing it back up and then I decided to remove the factory screen protector to see if that helped and it has gone from frustrating to usable. Samsung, in my opinion has always had the worst traditional FP sensors so I was very skeptical about how well their in-screen version would work. When I received the August security patch on day 2 and saw that improvements were made to the FP sensor as well I was pretty excited, but I didn't notice any improvement until I removed the screen protector. As others have mentioned Samsung really needs to add haptics to it.
