Unfortunately, the phone matters a lot, too. The LG-G4 that I used at Cherry Springs took far better dark sky photographs than any of the Samsungs that I've had since then. I think the key was that it had a 30 second exposure time. The Samsungs all topped out at something like 10 or 15 seconds. They are workable, but not quite as good (or, at least, I haven't found the right settings).
