Anyone have issues with burn ins on their AMOLED screens yet? I heard/ read a few stories of people seeing those after few months of usage. Is this a big issue with Android/ Samsung phones? Overall I love the screen of the Note 3 but I noticed that Samsung was "cheaping out" slightly on it by not introducing more real pixels but rather stretching to this new size. Not as noticeable only if you're really detail obsessed. There's also a fine dithering grain that I notice on solid color backgrounds which is not as nice as I remember on a iPhone LCD screen but again just a detail and not a deal breaker. Thoughts?
