New to Android, on my SG3, when I go to "videos", they are all playing. I'm afraid that its running my battery down. Is there a way to get that to stop?
They are not actually playing in the background as the phone is unable to play more than one video at a time. What you are seeing is an animation of several frames taken from your videos as thumbnail images that play in a loop while you are in the Videos app and in the thumbnail view. If you change the view, no animation is shown.
