I HATE on-screen buttons, but have never owned a smartphone with on-screen buttons.
The only button I want them to get rid of is that useless Bing search
Pretty sure phone calls are not over 50% of smartphones usage, or even the largest feature they are used for.Yes. I believe the primary purpose of a smartphone is to make and answer phone calls. It shouldn't involve so many steps.
battery saver turns them off [/EDIT]It is dark right now and my capacitive buttons blind me because they are so bright. I would like to use software buttons plus hardware camera buttons. I really like that the navigation bar can be set to your accent color.
