Three lenses for 3 different fields of view. 3 circles. how bad is that?
Not any holes for mediocre macro lenses or for depth sensors. I don't  know if you like photography but a wide lens, an ultra wide lens and a 3x tele lens is just very nice to have in 1 device and all 3 are directly available in the device. Now compare that in a compact camera where a zoomlens will interfere with optical quality or compare to system camera where one can switch primes, but it is a hassle and to what cost does one want to have better quality and control? No sir, Samsung and a lot of other smartphones with multi camera's destroyed the compact camera market.

Once again, a low end Galaxy phone looks nicer than any flagship phone. The number of lenses and general bling have gotten out of control lately.
