When I first picked up my Galaxy s7 Edge on Sprint, I wrote a post about poor quality, lack of stability, and a lot of people told me I was imagining it, or put it down to YouTube. Now watch this... That is a video I took in FHD60 (i.e. 1080p and 60 frames per second) - skip forward to 8 seconds. Unacceptable isn't the word. It's not usually quite this bad, other less severe samples are available on my YT channel, but this is one that is clearly irrefutable. This one is 4K. Not as bad on the face of it, but the weird motion blurring and blockiness present is ...well, it doesn't feel very 4K. I also experience some skips/frame drops when filming in this mode. I took approx 130 10-30 second videos over the weekend and skipping is present in most of them. I've even got to the point where I try and film everything twice (panning across a landscape) so i can hopefully minimize the likelihood of skipping. This is my second S7 edge, after the first one developed a dead pixel within the first 2 weeks. I've updated the firmware to G935PVPU2APD3. From what I've read online in forums, one user claimed that on a live chat , Samsung are refusing to admit it publicly, but there is nothing they can do to improve it. I believe this is a problem mainly with the US Snapdragon 820 chip - but I dunno, it could be an issue with the International version too - either way, I'm not happy but it looks like we have to put up with it.
