Cant switch back to phaser mode from Tricorder mode

Silly, fun app. It doesnt bother me at all that its not EXACTLY like the real Star Trek sounds. The thing that is a bit of a pain is that you cant switch back to the phaser screen once youve gone to the Tricorder screen. You have to exit the app and then go back in. Oh well... its only a buck.
