How to avoid TouchPhase.Ended effect?

I wrote a touch control script to control the camera for some basic 3d movements, like orbit around, zoom in & out and pan. Also, I want to reset my camera to default position. However, it seems that the TouchPhase.Ended always moves the camera after I press the reset button. Anyone can help to solve this problem.

     private void Update()
     {
         Touch touch = new Touch();

         // Orbiting
         if (touch.phase != TouchPhase.Ended && Input.touchCount == 1 && !EventSystem.current.IsPointerOverGameObject(touch.fingerId))
         {
             Touch touchZero = Input.GetTouch(0);

             _LocalRotation.x += touchZero.deltaPosition.x * 0.5f;
             _LocalRotation.y -= touchZero.deltaPosition.y * 0.5f;
             _LocalRotation.y = Mathf.Clamp(_LocalRotation.y, -90f, 90f);

             isOrbitting = true;
         }
     }
 
         private void LateUpdate()
         {
             // Orbiting
             if (isOrbitting)
             {
                 Quaternion QT = Quaternion.Euler(_LocalRotation.y, _LocalRotation.x, 0);
                 this._XForm_Parent.localRotation = Quaternion.Lerp(this._XForm_Parent.rotation, QT, Time.deltaTime * OrbitSpeed);
             }
         }
 
         public void ResetCamera()
         {
             if (EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
             {
                 _XForm_Parent.transform.localPosition = Vector3.zero;
                 _XForm_Parent.transform.localRotation = Quaternion.identity;
                 _XForm_Camera.transform.localPosition = new Vector3(0f, 0f, -10f);
                 Debug.Log("Camera Reset");
             }
         }
