I don't think is a setting problem. I had the same emotion when I saw fantastic images captured from smartphone and so I decided also to test this. I bought a pack at about 25$ with a macro lens. But the result was also very poor, and the main problem is that you have to be very closed to the subject. So for insect, it is about impossible. So I think, the photographers with smartphone have a very good macro lens, very good quality and so the price would be around 100$. Maybe I'm wrong, by the way it is just my feeling. So for now, I still continue with my Macro lens Raynox with my Lumix FZ200 camera...
