First of all, let me go on record as being a normal photographer with normal DSLR cameras. I do own a cell phone that I seldom use. It will shoot the simplest of photos, and I do not claim to be a wizard on the market.
I don't think that you will find very many cell phone cameras that have much in the way of "real" camera features like optical zoom. In a camera lens, optical zoom can be accomplished only by two methods that I am familiar with. One is the photographer actually grabs the zoom barrel on the lens and twists it somehow. The other is done by the photographer pushing some button, and an internal motor drives the zoom function. That latter method eats up battery power, so cell phone designers generally try to avoid it. There isn't enough lens to grab hold of for the first method. Even if there was, it would be the first thing to break.
Digital zoom is "crap," and I won't discuss it.
