How to close the application?

Question

Unity

put the method on the exit button

public void ExitGame(){
        Application.Quit();
        }

when you press it, it seems to close, but when you scroll through all the windows, I see that it hangs, if you select it, the game will start reloading again ....
How can I completely exit it?

Ps - Although in few places I notice the exit button ....

In case of low memory, Android itself will unload such applications from memory.
