> How else would you [learn to use it]? Randomly tapping elements on the screen and seeing what happens is a perfectly acceptable learning strategy for a child. From there, you might learn that an accent color can represent links; That a row of buttons, where one is emphasised, might be a tab-bar; That holding on an element will open a secondary menu; That little arrows represent folded content; that a list on the left might change content on the right; That certain icons always lead to similar functionality; Side note: OP's neice was wildly tapping the screen, because she likely learned that nowadays nearly everything is interactive (Go on YouTube and find me one element that can't be tapped).
