How to find the screen-size-in-points of a Samsung Galaxy S7
After some more research, I found my answer:  360 x 640, which are the same dimensions as the Galaxy S6, which are the same dimensions as the few preceding Galaxy S models.  

But I still don't know what these dimensions are called.  I found three different websites, each giving them a different term:


design.google.com:  "width x height in dp"
mydevice.io/devices:  "CSS width and CSS height"
viewportsizes.com:  "viewport size"
