|I would agree that the Note 4 is quite lacking in the ability to get close up. When you get close, the focus seems to constantly "hunt", and pictures I have managed to get are very soft, bordering on fuzzy. If I take a photo from a bit of a distance (about 6 inches or more), and crop the image, I get much better results, but overall, images are still quite soft, in my opinion. Lighting has to be pretty good too, to get a decent, sharp(ish) image.
Nowhere near as good as my Galaxy S4 was...it captured remarkable macro images.
Just my 2¢.
