Which app are you using? It sounds like it has crashed....swipe all the way down and wait for the App to "flip" and swipe it back up to re-launchI do have a keyboard but the escape key doesn't do anything. Swiping down worked momentarily but full screen came back as soon as I did something to change the screen. Now swiping doesn't work anymore!
Yes, that worked. I did wonder if it could be my swiping technique. Thanks!
