Four major companies design the key chips for smartphones....Qualcomm, Mediatek, HiSilicon, Samsung and Apple...

Could any well informed commentards help me and other ignoramii out by explaining who exactly does what?

On the fab side of things, I've got (I think) a good idea of what's involved, who's playing and who's paying. But on the design side, exactly who's actually designing what? Almost everything seems to be ARM based, but then Uncle Tom Cobley and all claim that they design their own silicon. Is ARM simply an instruction set? Or a code library? Or is the ARM element a core CPU component to which other companies bolt on third party IP to make an SOC? How complicated is this third party design - are we talking Shenzen generic levels of difficulty, or do the "designers" actually need to be chip design gurus?
