Thank you for your prompt reply to my question. When going to Customize Control I saw a minus sign not a plus and an option to Remove it. That told me I had it somewhere - but where? I expected it to be on the Home page at the bottom right but it wasn't there. Quite by accident I found if I swipe up from the very bottom so low that it is off the phone, I get a few apps, the flashlight being one of them.
