Question about the display: Somehow I have activated an app in the Xiaomi Redmi Note 12 Pro+ and no longer know how to deactivate it. It is the small (quarter) circle on the home screen at the edge, movable. If you click on it, further options open (rather useless). I can't figure it out, I've searched everything, but if you can't give the function a name, you can't search either. Does anyone know what to do? Do you know what I mean? Thanks for any tips.
