Wrong Orientation Detected After Application Pause

At present, I am working on game which work for both orientation landscape and portrait. But if I change my mode to landscape by rotating device and then I press device lock button and disable my screen. After some time, awake my device again. At that time, I am getting following weird view.

Here in above image, you are clearly seeing what is actual mistake exist. When I do screen on at that time, I am getting above kind of view.

I want to set like that if at screen off time landscape orientation is running then at screen wake up time same orientation need to be available.

For testing purpose I have written something like following code but didn't get any solution.

 void OnApplicationPause (bool pauseStatus)
     {
         Debug.Log("pause status : " + pauseStatus);
         if(screenViewOrientation == ScreenViewOrientation.LANDSCAPE_LEFT || screenViewOrientation == ScreenViewOrientation.LANDSCAPE_RIGHT){
             Debug.Log("enable landscape....");
             Screen.orientation = ScreenOrientation.LandscapeLeft;
             ActivateLandscapeObjects(true);
             ActivatePortraitObjects(false);
         } else if(screenViewOrientation == ScreenViewOrientation.PORTRAIT || screenViewOrientation == ScreenViewOrientation.PORTRAIT_UPSIDEDOWN){
             Debug.Log("enable portrait....");
             Screen.orientation = ScreenOrientation.Portrait;
             ActivateLandscapeObjects(false);
             ActivatePortraitObjects(true);
         }
     }

Please give some of your help in this.
