Lag with input touches, Unity3d problem?

Hello, I'm making a path drawing game and experiencing some lag with the input touches.

Sometimes you get a big gap between the points, when you quickly swipe a circle. I couldn't find the reason for this, so I tested it on the normal android SDK and experienced a much more fluently touch input. Does anyone know if this a Unity3D related problem, or am I doing someting wrong? Below you can see the screenshots(i can;t manage to place them right here due to some bugs with posting images on the forum, so scroll a litte downwards in my post to see them). Also I provided some code and hope someone knows a solution for this

Code (csharp):

1.  
2. function Update ()
3.  {
4.  if(Input.touchCount == 1)
5.  {
6.  // touch on screen
7.  if(Input.GetTouch(0).phase == TouchPhase.Began)
8.  {
9.  pos = Input.GetTouch(0).position;
10.  ray = Camera.main.ScreenPointToRay(pos);
11.  
12.  if (Physics.Raycast (ray, hit, 50) )
13.  hit.transform.gameObject.SendMessage("TouchBegan") ;
14.  }
15.  
16.  
17.  if(Input.GetTouch(0).phase == TouchPhase.Moved)
18.  {
19.  
20.  pos = Input.GetTouch(0).position;
21.  // pos = Camera.main.ScreenToWorldPoint(pos);
22.  hit.transform.gameObject.SendMessage("TouchMoved", pos);
23.  
24.  
25.  }
26.  
27.  
28.  
29.  if (Input.GetTouch(0).phase == TouchPhase.Ended || Input.GetTouch(0).phase == TouchPhase.Canceled)
30.  {
31.  
32.  hit.transform.gameObject.SendMessage("TouchEnded") ;
33.  
34.  }
35.  }
36.  
37.  }
38.  

The first screenshot is from Unity, the second is from Android:

 

are you using the remote? if so test on device.

 

These are screenshots from a real device, no remote.
