"Camera-shake" is a problem with cellphone (or small "point-and-shoot) cameras pics when trying to track and capture a distant object.
You could try to lean the phone's body on a stable object of some sort.......still it is "iffy", but possible >> especially if you take many photos, and happen to capture one or two good ones.......and discard the bad ones.
The DSLR cameras with super "long" lenses have the same problem.....but in a different way.......the weight of the camera+huge lens actually makes you "top heavy", and your human body is often reacting to a not-normal weight far above your center-of-gravity, and creates wobble.
I don't have a video type "fluid head on a tripod" (yet).....but it seems for distance shots.....this would be the way to go, as the ease in which you could pan and tilt the camera is much more smooth.
