WebCamTexture rotated 90 degrees

I've created a WebCamTexture that works correctly on BlackBerry 10, however when I run the project on Android the image is rotated 90 degrees. It's running in protrait mode. I know how to flip the image horizontally but not rotate.

 public class WebCameraScript : MonoBehaviour {
     public GUITexture myCameraTexture;
     private WebCamTexture webCameraTexture;
     
 
     void Start () {
         // Checks how many and which cameras are available on the device
         for (int cameraIndex = 0; cameraIndex < WebCamTexture.devices.Length; cameraIndex++)
         {
             // We want the back camera
             if (WebCamTexture.devices[cameraIndex].isFrontFacing)
             {
                 webCameraTexture = new WebCamTexture(WebCamTexture.devices[cameraIndex].name, Screen.width, Screen.height);
                 // Here we flip the GuiTexture by applying a localScale transformation
                 // works only in Landscape mode
                 myCameraTexture.transform.localScale = new Vector3(-1,-1,1);
             }
         }    
         // Here we tell that the texture of coming from the camera should be applied
         // to our GUITexture. As we have flipped it before the camera preview will have the
         // correct orientation
         myCameraTexture.texture = webCameraTexture;
         // Starts the camera
         webCameraTexture.Play();
     }
     public void ShowCamera()
     {
         myCameraTexture.guiTexture.enabled = true;
         webCameraTexture.Play();
     }
     
     public void HideCamera()
     {
         myCameraTexture.guiTexture.enabled = false;
         webCameraTexture.Stop();
     }
     
 }
