Cinemachine FreeLook jumps around on iOS

Hi,

I have a Cinemachine FreeLook Cam in a scene which can be rotated around a target. In playmode in Unity everything works as expected.
On iOS in my mind touching the screen shouldn't do anything until I move my finger and then the camera should be rotated from there. But instead when touching the screen the camera moves straight away and rotates from the new position when I move my finger.

How can I prevent that?

Thanks in advance

 

I made a short video to visualize what I mean exactly. In the clip I only tap the screen on the right, then on the left, right again, left again.
Why does it move the camera without me moving my finger?

 

I got it myself!

Found the following code online which I had to put into the scene. Now everything works as intended!

Code (CSharp):

1. using Cinemachine;
2. using UnityEngine;
3.  
4. public class CameraControlTouch : MonoBehaviour
5. {
6.     public float TouchSensitivity_x = 10f;
7.     public float TouchSensitivity_y = 10f;
8.  
9.     // Use this for initialization
10.     void Start()
11.     {
12.         CinemachineCore.GetInputAxis = HandleAxisInputDelegate;
13.     }
14.  
15.     float HandleAxisInputDelegate(string axisName)
16.     {
17.         switch (axisName)
18.         {
19.  
20.             case "Mouse X":
21.  
22.                 if (Input.touchCount > 0)
23.                 {
24.                     return Input.touches[0].deltaPosition.x / TouchSensitivity_x;
25.                 }
26.                 else
27.                 {
28.                     return Input.GetAxis(axisName);
29.                 }
30.  
31.             case "Mouse Y":
32.                 if (Input.touchCount > 0)
33.                 {
34.                     return Input.touches[0].deltaPosition.y / TouchSensitivity_y;
35.                 }
36.                 else
37.                 {
38.                     return Input.GetAxis(axisName);
39.                 }
40.  
41.             default:
42.                 Debug.LogError("Input <" + axisName + "> not recognyzed.", this);
43.                 break;
44.         }
45.         return 0f;
46.     }
47. }
