Mobile Phone - add picture

I only have experience on an iPhone, but in my experience when you go to add a picture, which presumably is a child table with just a few fields, including the file attachment field, when you are sitting in Add Mode on the child table and push the native button to upload the file attachment, the phone will ask if you want to use the camera, or use the camera roll. 

So it would seem to me if you select the option to take a picture then that's one step, right?
