Use Tasker to Enable Immersive Mode on Android Whenever You Want
Android: Some applications in Android may enter a so-called “immersive mode” that hides your buttons and status bar, giving you extra space. This Tasker action allows you to enable this mode for any application whenever you need it.
The tutorial below from XDA shows you how to create a dive mode switch. When you tap on it, the status bar and onscreen navigation buttons (if your phone uses them) are disabled, leaving you much more screen space.
To do this, you need Tasker and the Tasker AutoTools plugin . You can also use the AutoNotification plugin to add a dive mode switch to your quick setting shortcuts. Check out the full guide below to find out how to set it all up.
