I don't seem to be able to take vids on my iPad now I'm on the new iOS7 system. What I did was click on "camera" from which it's easy peasy to take pics. However, on the right hand side of the panel there is "video", "photo" and "square". "Photo" is always highlighted but when I press on "video" nothing happens.

Am I doing something wrong or is it teething probs with iOS7?

You do not click, you swipe up or down on the right to select video, camera or square
Also, touch camera roll on bottom right, to view your camera roll and touch camera at top right to switch between front and back camera
