If I were you guys, I would call Samsung Tech Support and complain about this problem. I've complained about it till I got fed up and sold my S3. They know about it, they've confirmed to me that some of their phones do it and some don't. If people don't complain, nothing will get done about it.
It does piss me right off though, as the phone has an excellent camera (apart from this problem) and it's the reason I bought it in the first place...
