The day before yesterday (Wednesday here) a bug appeared. My Android VLS is on landscape reverse mode for video-watching purposes. But this function has stopped working all of a sudden 48 or so hours ago. It no longer provides the functionality which was to auto-adjust between landscape view modes only, never reverting to portrait mode regardless of how I hold the phone. But "Landscape reverse" is now become the exact same thing as "Landscape" mode, which means only on one side fixed landscape form with no auto-adjusting capacity. What happened? Please undo whatever buggy update was done recently.
