EDIT: Confirmed that the note 3 (All variants, as tested from 3 Bestbuy stores and about 10 note threes) camera sucks terribly at focusing on dark objects or objects with little difference in color. I'm surprised nobody noticed this. It can't focus on certain spots on the hand at 8 inches away depending on lighting but there will always be a spot on the hand it fails to focus on, nor can it focus on various dark objects in good light. No kernel changes, roms, or AOSP kernel/rom will fix it. The note 3 camera just sucks at focusing. Tested this against a LG G2, and Htc m7 and they could focus properly to those spots on my hand in good light that couldn't focus on.
