Do you think that the sensors in flagship phones take up significant space in the phone or are significantly larger than the sensors in smaller or cheaper phones?
I might agree that a smaller phone can't have like FIVE cameras, like some of the flagships, but they can certainly fit the same high-end sensors themselves.
I'm afraid I don't know. Perhaps I assumed wrongly. But having taken apart a couple of phones and knowing how tightly packed everything is, I expect the sensors, lenses, processing chips and whatever else of better cameras would be harder to fit into whether phones. Besides, isn't the high end nowadays often about the postprocessing taking advantage of the multiple cameras?
