To the untrained eye, it seems as though the iPhone X and the iPhone XS are identical. They both have the same screen, the same dual camera, and the same dimensions, so it would stand to reason that any old iPhone X case would fit fine.
That's not the case. Although some case makers were originally simply rebranding their iPhone X cases as iPhone XS cases after the Gather Round event earlier this month, things have changed since the iPhone XS started shipping. Apparently, the camera bump is imperceptibly taller on the iPhone XS, which is causing issues with some stiffer cases.
