OnApplicationPause in Android

Unity have OnApplicationPause && OnApplicationFocus to handle when press home button or power button.
now I have a feature is that I want set Camera to a specific position when OnApplicationPause.

Code (CSharp):

1. private void OnApplicationPause(bool pause)
2.     {
3.         if (pause)
4.         {
5.             Debug.Log("OnApplicationPause true");
6.             Camera.main.transform.position = new Vector3();
7.          
8.         }
9.     }

In document, unity says "One extra frame will be issued after OnApplicationPause is called to allow the game to show graphics that indicate the paused state."
but I test it on Android, it didnot render actually, it renders when application come into front, in my case is the screen have a splash and camera go to the position I set in OnApplicationPuse.

Did I miss something or Android didn't support this?
