Using EasyTouch3.1 with a problem(gesture.deltaPosition)

Hi,
I have switched my project from PC to Android but now my calculations aren’t working anymore. Especially the gesture.deltaPosition.x it just returns 0 on the Android and Windowsphone Device. But when I run it in Unity editor itself it works.
Why is that???
And how should I do???

void On_SwipeEnd(Gesture gesture)
{
Debug.Log(“On_SwipeEnd” + gesture.deltaPosition);
}

I found the solution!!!

 void On_Swipe(Gesture gesture)
 {           
     this.m_BackupMousePosition = Input.mousePosition;
 }

 void On_SwipeEnd(Gesture gesture)
 {
     Vector3 deltaVector = Input.mousePosition - this.m_BackupMousePosition;           
 }
