On early versions of Sakura, when you watched a video, if you touched the bottom line of the lower screen it would display the lower screen as a blank screen with only the video playing on the top screen, which seemed a good feature for extending the battery life whilst watching a long video.
I notice the newer versions of Sakura no longer appear to have the above stated feature of the lower blank screen option and either show only the video on both screens or the controls on the lower screen and the video on the top screen. Does anyone know if the blank screen feature been taken away from the newer versions of Sakura or is there a different way to recover this function?
