Anyone notice all the camera setting on this phone..jeez...I have no idea what half that stuff is...lol...as you look in landscape mode, top icon on right where it say auto, if you swipe it down there are several more options iso setting, saturation, etc... anyone know what all those do, and top left tap on the screen gives you bar to adjust light, what exactly does this do, there is already a white balance setting on the right third icon down. Love the camera, but it is a little much, auto takes great pictures as long as you have a lot of light, outside daytime, low light indoors, not so good, comes out very grainy. So I guess I need to learn these setting to get them better. Any advise will help
