Is there no live preview or review/playback on CGO4?

I just purchased H920 with CGO4. I have been able to figure out most of the camera menus but I can't seem to locate a live preview or a review/playback button so that I can check photo either right before or right after I take it. Is there no way to preview/review images while operating camera? I'm OK at guessing manual exposure settings but would still like a quick preview or review so I can visually verify that exposure is correct. I don't see a histogram or any other tool for exposure checking. Am I just missing it?...or is it just not there?
