Not sure if this has been picked up on but whenever I make my lock screen wallpaper a photo I've taken on my iPhone 7 (Still, sized to fit the screen by pinching etc.) – makes the picture on my lockscreen blurry? This was not present in iOS 10.0.1 on my iPhone 7 but I also don't remember having this on my iPhone 6 running iOS 10.0.1, but now present on 10.0.2 (on my iPhone 7, sold the iPhone 6). It actually seems it's any sort of photo made as the wallpaper. Example: http://imgur.com/a/dPbyC. Bug?
