Thanks, ill try as soom as my wife gets back, its her phone. It a Samsung a51 I believe. A widget might be it. Ill post results.What make and model phone?
Have you tried long pressing the center of the icon to see if it gets you options? Or long pressing and dragging it off screen?
Try searching in settings for dim or contrast. Try looking in accessibility for an option. Try looking in your widgets.
That's all I can think of. I'm not seeing a similar option in my Samsung.
