Check your photos for any new pixel distortion /low resolution. Many new documented cases in last week. Samsung now aware and can now replicate it on sample phones but no known cause or fix. Not ALL photos will be affected, but the ones that are can be new from camera, transferred, downloaded or someones facebook, insta etc.. photos online. Will progressively worsen. The more documented cases the quicker Samsung will get an update out. In mean time, I can get a replacement but I'm past 14 days and I don't get a brand new phone, just certified refurbished.that is just BS. I imagine many Note 5 users have not even noticed it yet bc its random photos. It is a software defect. Any Note 5 users experience this screen resolution issue yet?
