Kids try out things and are great at memorizing arbitrary stuff. They're 
necessarily also vastly more smart than adults, in the sense of more 
flexible thinking and self-adjustment, though without the knowledge base 
that lets those smarts manifest as recognizable or measurable adult 
level intelligence. So when the UI changes (new phone, update, whatever) 
they just try out things and memorize the new ways, plus they 
communicate about such things so they can learn from other kids.

Adults rely more on a fixed established knowledge base, and the ability 
to apply a once learned set of rules to figure out how to do things, and 
many adults are prevented socially (I'll look dumb if I ask! I'm afraid 
of being put down!) from communicating much about such things.

An adult will explore but systematically, in accordance with the once 
learned rules, where kids will explore more at random. An adult has 
expectations, and can have "WTF?" reactions and back off, where a kid 
just happily accepts whatever happens and doesn't limit itself to what 
an adult may think is sensible.
