I don't know why this started to happen. I can't play the videos in my camera roll. I have a lot of videos on my iPhone, and I can't view them. I see the thumbnail, and when selected it has the loading wheel and it doesn't play. When trying to import to my iMac it says it's an unreadable file, but why could have it gotten corrupted? I have so many memories, and I would hate to lose those videos. Has anyone else had this problem? I looked somewhere else, and it's the same problem I have. It hasn't been resolved though. Here's someone else's problem: Some videos from a few months ago that I have saved to my camera roll won't play. What comes up is a little loading circle like it is trying to load the video but it never plays. I know for a fact that when the videos were saved, they worked. All of them are saved videos from snapchat, but some work and others don't. Does anyone know how I can solve this problem?
