Ok I will let you in on the secrets. Remove any case your phone is on. Activate your camera app. Install the clip on lens. I had to be careful to get it exactly over the lens.
Get a newspaper or magazine or some junk mail and lay it flat. Bring clip on lens down to the print. There is a small plastic standoff on the end of the lense. Bring the lens right down till that standoff touches the paper and move it around slowly. I had to fool around a little to get it working.
My issue is the slight shake from taking the picture causing the blurry pic. Hard to do at high magnification
