Screen.Height not getting the correct value

Hi everybody, I'm Having a issue with screen.height in Unity Android, no matter wich resolution I choose to test, screen.height always give me the same value.

screen.width works perfect, but screen.height is always the same value and I dont Know why.

Here is my code, and What I'm trying to do, is to organize Touch Buttons on Screen.

 public enum Buttons{Joystick1,Joystick2,buttonA,buttonB,pad,pause}
 var controlType:Buttons;
 var Control:GUITexture;
 var screenHeight:int; 
 var screenWidth:int; 
 var textureHeight:int=60;
 var textureWidth:int=60;
 var customInsetX:int;
 var customInsetY:int;
 
 
 function Awake()
 {
     screenWidth = Screen.width;
     screenHeight= Screen.height;
     
 }
 
 function Start () {
 
     if(controlType==Buttons.buttonA)
     {
         Control.pixelInset=Rect(screenWidth-customInsetX,screenHeight-customInsetY,textureHeight,textureWidth);
     }
 }
