2D mobile touch error in build games

Iam having problem on fixing the hold touch input on my build game. The code works on remote but never works on build games.Can anyone help me? Here is the code:

Code (CSharp):

1. if (Input.touchCount > 0)
2.         {
3.             Touch touch = Input.GetTouch(0);
4.             acumulatedTime += touch.deltaTime;
5.  
6.             if (touch.phase == TouchPhase.Began)
7.             {
8.                 if (acumulatedTime < holdTime)
9.                 {
10.                     //touch code
11.                 }
12.             }
13.  
14.             if(touch.phase == TouchPhase.Stationary)
15.             {
16.                 if (acumulatedTime >= holdTime)
17.                 {
18.                     //hold code here
19.                 }
20.             }
21.  
22.             if (touch.phase == TouchPhase.Ended)
23.             {
24.                 acumulatedTime = 0;
25.             }
26.         }
27.     }
