works well On computer but not on phone,reads well on computer but not on phone

Ok i made some code that reads fingure swipes.. if i swipe to the right the object is suppose to go to the right and when i swipe to the left the object suppose to go to the left. I used the unity remote to help me debug and it works well when i use the remote but when i build and run the object doesn't move. it seems that touchphase.ended always equals 0 when its on my phone .` var Ball : GameObject;

function Start () {

}

function Update () {

 if( Input.touchCount > 0){
         if(Input.GetTouch(0).phase == TouchPhase.Began){
             var startPos : Vector2 =Input.GetTouch(0).deltaPosition;
             // Spawn Ball//
             Instantiate(Ball, new Vector2( startPos.x, -4), Quaternion.identity);
             
         }
         if( Input.GetTouch(0).phase == TouchPhase.Ended){
             var endPos : Vector2 = Input.GetTouch(0).position;
             
             GameObject.Find("Newtext").GetComponent(TextMesh).text = "relse" + endPos; 
         }
             Debug.Log("Start " + startPos);
             Debug.Log("End " + endPos);
         if ( startPos.x < endPos.x){
             GameObject.Find("Ball").SendMessage("MoveRight");
             }    
         else if( startPos.x > endPos.x){
             GameObject.Find("Ball").SendMessage("MoveLeft");
             
         }
