Can your cellphone identify the chemical composition of rocks 1000 feet underground, or scan someone for invasive pathogens, or identify lifeforms 10 KM away?
This disappoints me so much because it's just a toy, when we have the technology to make a scanning device that is basically a real one (not as magically good, though). I've seen phone addons for scientific research that can scan things for various things. Like a glucose monitor, Geiger counter, barometer, light sensor, blood pressure monitor, and more; with no reason why a single device couldn't have all of these things in one other than maybe cost.
