Why do phone cameras "click"?

Wednesday, January 2, 2019

It struck me the other day that it makes absolutely no sense to have phone cameras make a "click" like an old mechanical shutter. Many of the people taking pictures have never used a camera with a mechanical shutter. Since the death of Kodachrome (TM) I am not sure how many people have. So, why not have the phones quack like a duck or make some other noise?
