A way to make header go away full screen on the iPad?

I don’t see a way to do it, but maybe I’m missing it. Is there a way to make the information at the top of the screen go away in full screen so that there is nothing but the text that you write on the screen? I’m referring to the arrow, the word ‘Incoming’ and the menus to the right side, up to and include the word ‘Done’?
