To be honest, the best thing to do if you are encountering this problem regularly is just to force close the app after you exit it. This is as easy as pressing the recent apps button and swiping it off the list. ...

OH, that was way better than before. The back button didn't work, but the recent apps button did, and I closed the app, then opened it again. My update from a few minutes ago is there and all the keys seem to be there. I don't know if it managed to initialize anything that has replaced what was recently there, but so far it seems fine. Thanks for the instruction in your previous note.
