Some content is best experienced in fullscreen mode, like videos, games, image galleries, books, and slides in a presentation. Fullscreen mode can be enabled in the app code Depending on the app or content, the proper fullscreen mode will be activated automatically for example in Youtube, Netflix some gaming apps etc. But there is no way to disable or hide the navigation keys at the bottom of the screen nor the status bar at the top in the settings of the phone.
Let me know if you have any further questions!
