I just did a RTH since I can't get out of FULL SCREEN mode on my Galaxy Note 8 (it is on the list of phones supported). I tried to find ANYWHERE that would talk about this simple feature but google fi didn't find any.

Where is a user manual for the APP that is used with DJI MAVIC 2 Android?

Hi, we're sorry for the inconvenience. You can enter and exit the full-screen mode of the DJI GO 4 app by swiping the screen of the mobile device up and down. This option can be set in the General Settings of the application and look for "Full Screen Mode" Hope that this would clarify your query. Thank you for your support.
