Input GetTouch not proper

I am using Unity 5.6.2.
Input.GetTouch(0).position and Input.GetTouch(1).position giving same position. Does anyone facing the same issue?

 

Hello

I tested code below with Unity 5.6.2f1, and it works fine on Z2, Z4 model

Code (CSharp):

1.  for (int i = 0; i < Input.touchCount; i++) {
2.             Debug.Log (i + " " + Input.GetTouch(i).position);
3.         }
