Immersive Mode not working correctly

Hi,
I was wondering if unreal’s android immersive mode is bugged or if I missed something to enable.
Since Android 10 there is the new mode with fullscreen gestures, which removes the menu bar.
In my project settings I’ve enabled Platforms>Android>“Enable FullScreen Immersive on Kitkat and above devices.”
That works fine, but only if I disable the fullscreen gesture mode on my device and use the default mode. But with the fullscreen gestures enabled I get these cutouts/letterboxing (red), but only with my project not with other games (e.g. Fortnite works fine and uses the whole screen).

In Androids fullscreen settings, my game project is disabled per default, and if I enable it, it uses the whole screen. But I didn’t need to do that for the other games, they were already enabled, so how can I set that by default, like the other games have, if the setting mentioned above doesn’t seem to do that?

Thanks, :slight_smile:

Finally, found the solution:

add: android:maxAspectRatio=“2.4”
to the extra trags for “activity” or “application” inside the project settings.

Because apps need to be explicitly flagged to support a screen aspect ratio of 18:9.
For some reason the setting inside project settings (“Android>Maximum supportet aspect ratio”) has no effect.

Thanks for the information! I was trying to have fullscreen support for my game and stumbled upon your topic. Unfortunately adding extra tag as you suggested doesn’t work on 4.25. But fortunately, there is a setting to do that. Search for the entry “Maximum supported aspect ratio” and set it to 2.4 and done!
