Those settings are all stuff a photographer would understand. I haven't looked at what is available myself.
ISO, shutter speed, and aperture are settings for a camera that allows you to control the amount of light that reaches the camera sensor. They all perform together to get a proper exposure and all perform semi-dependently to create an image of your choosing (when adjusting one for a specific reason, you have to adjust another to achieve the proper exposure again.) Any preset condition that you can set for specific purposes are predetermined (poorly) settings of those 3 things to create a photo of a specific purpose.
The camera sensor on the phone is terrible. It works fine for viewing the photo on the camera itself, but is horrible image quality to use outside of the camera. If you want to take photos of quality, you need a dSLR camera. If you want a camera for snapshots you need a good Point and Shoot camera. If you don't want to carry 2 devices (P&S camera and phone) and want to take snapshots that are usable you need an iPhone. The iPhone camera rivals many of the P&S cameras available out there.
