You could make some good money making holders/mounting devices for phones that act as cameras.
@bryan_johnson1 whilst this is a good idea there is already plethora of options when it comes to mounting or positioning the camera device. What would be beneficial is a waterproof phone case/cover but with the many different positions of the camera front and rear it could be impossible to conceive an universal option.
I fashioned a holder with a business card and two medium size binder clips. It works great.
