The default browser of Lumia 920 (I presume IE 9/10) is great it is faster, smooth, but there is one small problem. There is no way of showing / hiding the navigation bar. When you are reading something then the navigation bar takes vital area of the screen. In my old Nokia N900 the default browser automatically happened to hide when you a page loads and by simply tapping a button the navigation bar appears. Is there a way we can show / hide the navigation bar while doing lengthy reading or make the browser full screen?
