Mobile settings

Hi everyone,
I’d like to optimize my mobile game.
I created a game with 600 * 800 resolution.
I entered the action “full screen” at the beginning of the scene.
The preview is perfect, but when I try to load on the Android phone, the down half screen in green.

On the internet, the developers suggest creating apps that handle different settings based phone screen. Is it possible to use the same technology in Gdevelop?

What are the best practice to set mobile game ?

Thanks,
JJ

This is the effect with “fullscreen mode”

.
