Found the issue. First off, I’m brand new to iPhone, the last twelve years or so was with Android and before that I was with Windows Mobile. This is week three and a half with Apple, so I was flying blind here trying to work the problem.
But, I did figure it out, and somehow I had managed to turn on the portrait mode lock. I searched all through the settings but didn’t think about the quick settings or whatever they’re called. Those are the settings you get to by pulling them down from the top of the screen. Went through those one by one until I found the portrait lock and just unlocked it. Now everything is good again. Thanks for the help.
