So I took some pics with friends, and when I went back to look at them the pictures were "animated", like short 2-3 second videos. I then looked at some older photos and they were the same, although when I looked at them in the past they were just stills. Then it stopped and they all became regular stills again. Any idea how that happened? Can I make it happen again? It was pretty cool. Maybe it's some feature I'm unaware of.
