I observe that in miui they have full screen feature in notched screen smartphone so that they can use notched supported app and gams too .. for example pubg . They can play in full scren mode ... but not in one ui ... can we get this feature in our devices
did you go to fullscreen apps and check whether it has been set to auto or fullscreen? i had the same problem in amazon primevideo which resolved after i set it to full screen
