Most of you probably know this

but the volume button works as a camera hardware button. I've read complaints about the phone not having a dedicated button so, if you don't know, you might want to try it. Nokia isn't alone in this. My Huawei mate 9 also works like that. A dedicated button would be nice, but this is still better (to me) than having to touch the screen to take a pic.

And you can use the column rocker on the ear buds and that causes no camera movement.
