I want to be able to remove the bar with the button to take photos, go into settings, etc. This is because I am going to put my phone into a virtual reality box. I would like the button to return to the page with all the different effects to still be there. Maybe up in a corner and in a way that you can still see the button, but it's hard to see. I will also be removing my ads soon. So basically, I want it to be possible to have a screen that is showing the live video and no toolbar with all the buttons on it, the only button I would want to be on the screen is the button to return to the menu. Thank you!
