Like the title says, anybody know how to do this? This is how it used to work on my Note 9. I'm using the Z fold 6 now, and the app that I'm on gets "zoomed out"/no longer stays open (you can see what I mean in the images).
Task switcher on Note 9, the current app remains visible in the background.
Task switcher on Z Fold 6, the current app does not stay open in the background.
Bring up the multitask window, then click on the app icon you wish to keep open, and a menu should appear. Choose "Keep open" to lock the app or "Open in pop-up view" to have it open in a smaller window.
That's not what I'm talking about, in the screenshot from the Note 9 the app stays visible and open in the background in full screen no matter what app it is when I use task switcher. What you're mentioning doesn't keep the app visible in full screen when using task switcher, the app I'm using still "zooms out". Also even if it did work, you'd have to do it for every app individually which I never had to do on my Note 9.
