I’m pretty sure that the multiple cameras all have different focal lengths, which allows the software to composite a single image from the multiple signals. This allows the intersecting fields to enhance quality when zooming and discriminate smudges/dust that you wouldn’t want to be in the shot.
Some phones do have four cameras on now. God knows what they all do.
