Same exact issue for me. Took a picture at 8:20am and then another at 11:50am and noticed that one was blurry. Lens shattered. Spigen case on my phone and did not drop it or even sit it down in those 3 hours. In my pocket with nothing else. Ridiculous. Samsung says they are unaware of it and cant read this "3rd party" forum with everyone else having the issue. It had to come from a drop or external pressure they say. I had to submit a claim through Asurion for $200. Awesome. Thanks Samsung.
