I noticed that the auto preview video is no longer a function in gallery. I actually loved that feature. I was able to watch a whole video without actually clicking on play. It was a good feature to watch a video without sound disturbing others, but now the feature is gone. What a bummer! How could people complain about that?!?!!!
@Tee88: Sorry to hear of your disappointment regarding this feature. As a workaround, when you capture a video using the Camera app you should see a circular shortcut to the video/Gallery in the bottom left corner. Tap that to open the video, then tap the mute button in the bottom left of the screen to enjoy it without sound.
