I hear this complaint a lot, but what is the solution exactly? Cramming labeled buttons for every possible action onto every screen? There's not a lot of space to work with, and even less when the touch targets have to be large enough for a big fat thumb to press accurately/reliably. You can do most of the things that most users need to do just knowing how to tap icons and swipe up to go home. I don't think it's such a big issue that there are some power user features that you either discover by messing around or word of mouth.
