Most camera lenses do, and generally give a wide range of stops, often down to f22. Phones have, until now, fixed aperture, fixed lenses.
Given how tiny phone camera lenses are I'm surprised to see variable, given how little range you get from two fixed stops. Course it may be the first move towards having a proper range of f stops, which can only be a good thing.

With a fixed aperture, increased low light sensitivity usually brings lower resolution (so called "fast" lenses generally have improved optical characteristics with their aperture stopped down). That is unless these dinky sensors are diffraction limited at f/1.5, which I doubt.
