I don't really have any good hints, but it did take me a while to master the swipe page turn. When I first started trying to do it, I could only get the page to turn when swiping very rarely. I've been practicing for awhile and now it works pretty much every time. Most of the time I actually swipe over the top of the touch screen--where the "n" is--and that seems to work well for me.
