Also I just wanted to add to this - MKBHD has just posted his video about this, and he wasn't able to reproduce what the reddit user did. Samsung did improve the photo of the blurry moon, but nowhere near as much as that guy on Reddit shows. That's not saying that he's lying of course - it's just that maybe we need to take it with a grain of salt.
