I got this idea after seeing an ad for something that is called a Selfie stick. It is just this little gadget. I guess that it is about a foot or so long and on one end of it is a place where you can hold your smart phone. The other end has a button and you apparently connect it to the camera on your phone via blue tooth. That seems kind of dumb to me to tell the honest truth. At least I am pretty sure that I would feel like a fool if I were out in the public eye holding this thing and taking a selfie. Of course it is not a bad idea aside from that fact, and if it worked well enough that might make it less of a problem. Personally I really do not take a lot of selfies. Unless I am with some person who wants to do it I do not do it.
At any rate I am thinking that are probably better ways to accomplish the same thing. You can mount the smart phone on one of those little tripods and they make those with flexible legs. That would make it so that would you could mount the contraption on almost any thing that you could think of. Another idea I had was to make a cell phone case which has a suction device in it. Obviously it would not be a terribly easy thing to design so that it was both compact and able to function the way that you want, but this would be great in a building or even near a wall. If there was a flat surface any place you could stick the phone to it and then you would just need a remote for, like the one for you car door.
