Hey Dwayne, first time Androider and then iodéOS right away - respect!
I had been in your position, too, and thought, why don’t they deliver instructions with it just like they did with any video recorder or printer? There used to be a manual that gave terms to all of the different switches and displays and … on the device.
Did not find one, sadly. Would be a very cool feature for any newby!
What you talk about is called the “top bar”. You could make a screenshot and post it here, so we could help you.
