Why do smartphones have triple-quadruple cameras when “dedicated” cameras have just one? What makes it better and why do we not see the 3-camera setup on actual cameras then?

a full size camera will have a telephoto lens, or interchangeable lenses for different fields of view and close ups.
a phone isn’t thick enough to install a telephoto lens, so they install 3 lenses, a wide angle for group photos, and longer lenses for zooming in on stuff that’s far away.
phones with only one camera will have a digital zoom which isn’t an optical zoom. it will just make the picture look bigger, but if you look closely it will have less sharpness. same as if you zoomed in on a photo that was already taken.
