Another huge problem I've experienced with phone cameras is that they seem to all need to autofocus before taking a shot. This is horrible for, say, trying to take a picture out of a car's window as the car is moving, as the phone camera keeps refocusing on different parts of the scene, so I often miss the shot I need to take.

Any DSLR (and even many non-phone point-and-shoot cameras) have manual focus, so this is just not an issue with them.

Other problems with phone cameras are relatively slow shutter speeds and poor low light performance compared to DSLRs.

Phones can also only do digital zoom, which is horrible compared to a DSLR with a zoom lens. There's no way to put lens filters on phones either. They can't do infrared photography, etc, etc.

Lots and lots of ways that phones simply haven't caught up to DSLRs yet.
