    I am fairly new to Unity so I am probably making a simple mistake, but I'm trying to change screen orientation for a simple 2D scene and it is not working.

    I have written the following test script that is attached to the main camera:
    Code (CSharp):
    1. void Start()
    2.     {  
    3.  
    4.         Debug.Log("Orientation: " + Screen.orientation.ToString());    
    5.         Screen.orientation = ScreenOrientation.LandscapeLeft;
    6.         Debug.Log("landscape left: " + Screen.orientation.ToString());    
    7.         Screen.orientation = ScreenOrientation.LandscapeRight;
    8.         Debug.Log("landscape right: " + Screen.orientation.ToString());    
    9.         Screen.orientation = ScreenOrientation.Portrait;
    10.         Debug.Log("portrait: " + Screen.orientation.ToString());    
    11.         Screen.orientation = ScreenOrientation.PortraitUpsideDown;
    12.         Debug.Log("portrait UD: " + Screen.orientation.ToString());
    13. }
    This is what appears in Android Logcat:

    This is running on an ASUS ROG Phone 5 via USB debugging. What am I doing wrong?

    You're calling all those calls in single function, meaning one frame. You cannot change orientations 4 times in one frame.

    That's not the issue; it still doesn't work when only called once.

    After some further testing, it seems that the orientation takes several frames to update.

    This code:
    Code (CSharp):
    1.     void Start()
    2.     {  
    3.         Debug.Log("Initial Orientation: " + Screen.orientation.ToString());    
    4.         Screen.orientation = ScreenOrientation.LandscapeLeft;      
    5.     }  
    6.     void Update()
    7.     {      
    8.         Debug.Log("Orientation: " + Screen.orientation.ToString());
    9.     }
    Gives this output:
