Well, a while ago My iPad was stuck on mute, so I checked through all the settings and found I can select whether to using the bottom bar, which you put by pulling up with 5 fingers, if I want to mute or lock rotation, but which ever one I choose, I cannot change the opposite, so its always locked on rotation or muted. Any help?
