Galaxy Z TriFold: How to Make Every App Full Screen

Quick summary: On the Galaxy Z TriFold, some apps (Yelp was my example) open in a narrow window instead of filling the screen. The arrow buttons just move the window around, and turning the phone sideways is annoying. Two settings fix most of these apps, and the same fix works on the Z Fold phones.

Part 1: Allow landscape view

1. Open Settings. (Quick tip: search for “portrait” if you can’t remember where it is.)
2. Go to Advanced features > Labs > Landscape view for portrait apps.
3. Turn it on for any app that’s acting weird. This forces apps that normally only support portrait to show in landscape when you hold the device horizontally. Samsung notes some apps may still not fill the entire screen.

Part 2: Force full screen

1. Go back to Settings > Display > Aspect ratio (most apps are set to App default).
2. Find the app. Search by name or scroll down the list.
3. Change it to Full screen.
4. Go home and open the app. Yelp now fills the whole screen, in both orientations.

If it still doesn’t work

It might not work for every app. Try closing the app (or all your apps), then go back into Aspect ratio, set the app to App default, then back to Full screen, and open the app again. Reddit had this problem at one point, and it now runs full screen in landscape too.
