Background changed to black using iOS 14.3 on iPhone 11
The background is black when I use apps like Message and email. It was white and I'm not sure why is changed to black suddenly. I have tried changing the dark mode on and off. (I have not used dark mode because I don't like it.) I can't seem to get the screen back to a white background. The exception would be Apple Books because the is a font and color option in the app.
Any suggestions would be greatly appreciated. Sue K
