There's a button with four arrows in the upper-left corner of the browser (Android 3.1 tablet), you press it to toggle in and out of full-screen mode. I'd like to hide that button when I'm in full-screen mode so I truly have use of the full screen. Is there any way to do that? (Of course, then I'd need some other way to get the browser OUT of full-screen mode...)

Thank you for your help!!
