iOS ecosystem also has a problem with gratuitous UX changes. E.g. that physical Home button on early models was a godsend for non-tech users - if they found themselves somewhere unfamiliar, it was always there as an escape hatch, without doing anything non-obvious like swiping from the edge. And then Apple killed it.

Another frustrating thing on the notch devices is that they put the control center on top instead of the bottom. Years of muscle memory down the drain.
