Since there's no pinch-to-zoom, you're stuck using the on-screen buttons or double-tapping, which in our experience didn't work as flawlessly as we would've liked.
Notifications can be cleared out with a single long-press, chat heads can be dragged around anywhere on the screen, double-tapping a photo marks it as liked, and flipping through status updates is as easy as swiping left or right.
Earlier we mentioned that Popup Video is available on the Note II, but that isn't the only thing that pops up -- you can do the same thing with Popup Note, which is activated by holding the S Pen button and double-tapping on the screen.
