Screen shots

Pull out your sPen and use smart select, you can crop it out real quick
 
Taking a screen shots in landscape is kinda awkward with both buttons on the left side...
Not sure why it's awkward. I just tried it, and it was every bit as easy as portrait. Just tap volume down and power at the same time quickly
 
I either just tell bixby "screenshot".
or use my Spen as I usually annotate my captures so I remember why I took them out to outline something or draw or Palm swipe. never liked having to use the side buttons but that works too.
