Character Controller Initial Problem With Mobile

I am having my mobile Joystick Programmed as below...

When I touch first joystick or use joystick at first time in mobile it stuck and character controller also get a bit glitch and then after first touch it goes very smooth as per other mobile joysticks..

where i have made mistake ...please someone try me to solve this

using UnityEngine; using UnityEngine.UI; using UnityEngine.EventSystems;

public class Mobile_Joystick : MonoBehaviour,IDragHandler, IPointerUpHandler, IPointerDownHandler {

 //Public Variables for editior editing
 [Header("JOYSTICK SETTINGS:")]
 [Range (0,2.5f)]
 public float Stick_Move_Range;                    //Stick Movement Radius
 [Tooltip("Hide Joystick While Not Being Used.")]
 public bool Hide_On_Idle;                            //If Stick Should Be hidden when in idle state or not using or not touching
 [Tooltip("Alpha of Stick When Not Being Used.")]
 [Range (0,1f)]
 public float Alpha_Fade_Stick;                    //Alpha of Stick when Joystick is not being used
 [Tooltip("Alpha of Joystick Base When Not Being Used.")]
 [Range (0,1f)]
 public float Aplha_Fade_Joystick_Base;            //Alpha of Joystick base when Joystick is not being used









 //Private Variables
 private Image Joystick_Base;                 //Joystick base Image
 private Image Stick;                        //Stick Image



 //Some Vectors

 private bool Is_Touched;                                //Bool is touched or not
 private int Current_Finger;                            //Current Finger ID Which is Touching
 private Vector2 Touch_Position;                             //Store Current Position on Joystick
 private float IO_X;                                        //Gives Current Distance From Center.x To Finger Touch
 private float IO_Y;                                        //Gives Current Distance From Center.y To Finger Touch
 private Vector2 InputDirection;                        //Store Output
 private Vector2 Final_Input;                            //Stores Final Output 



 void Start(){
     
     Joystick_Base = GetComponent<Image>();               //getting image componnents
     Stick = transform.GetChild(0).GetComponent<Image>(); //this command is used because there is only one child in hierarchy
 }




 public void OnPointerDown(PointerEventData data){
     if (!Is_Touched) {
         Is_Touched=true;
         OnDrag (data);
         Current_Finger = data.pointerId;
     }
 }
 
 public void OnDrag(PointerEventData data){

     if (data.pointerId == Current_Finger && Is_Touched) {
         //To get InputDirection
         RectTransformUtility.ScreenPointToLocalPointInRectangle
         (Joystick_Base.rectTransform, 
          data.position,
          data.pressEventCamera,
          out Touch_Position);
     
         Touch_Position.x = (Touch_Position.x / Joystick_Base.rectTransform.sizeDelta.x);
         Touch_Position.y = (Touch_Position.y / Joystick_Base.rectTransform.sizeDelta.y);

         //As Per Pivot It Sets Values
         IO_X = (Joystick_Base.rectTransform.pivot.x == 1f) ? Touch_Position.x * 2 + 1 : Touch_Position.x * 2 - 1;
         IO_Y = (Joystick_Base.rectTransform.pivot.y == 1f) ? Touch_Position.y * 2 + 1 : Touch_Position.y * 2 - 1;

         //Normalize the Input For Our Joystick Movement
         InputDirection = new Vector2 (IO_X, IO_Y);
         InputDirection = (InputDirection.magnitude > 1) ? InputDirection.normalized : InputDirection;

     

         //to define the area in which joystick can move around
         Stick.rectTransform.anchoredPosition = new Vector2 (InputDirection.x * (Joystick_Base.rectTransform.sizeDelta.x / 3)*Stick_Move_Range,
                                                             InputDirection.y * (Joystick_Base.rectTransform.sizeDelta.y / 3)*Stick_Move_Range
                                                             );
     }
 }
 

 public void OnPointerUp(PointerEventData data){
     if (data.pointerId == Current_Finger) {
         Is_Touched = false;
         InputDirection = Vector2.zero;
         Final_Input = Vector2.zero;
         Stick.rectTransform.anchoredPosition = Vector2.zero;
     }

 }


 public Vector2 Joystick_Input()
 {
     //Our FInal Vector Which Holds Inputs
     Final_Input = new Vector2(InputDirection.x,InputDirection.y);
     return Final_Input;
 }

 

}

This gives me output and i am taking its output to my fps controller and its scripted like below

using UnityEngine; using System.Collections;

public class FPS_Controller : MonoBehaviour {

 [System.Serializable]
 public class Script_Resources{
     public Mobile_Joystick Joystick;
     public Mobile_Touchpad Touchpad;
     public Camera FPS_Camera;
 }
 public Script_Resources Resources;

 public float Speed;

 private Vector2 Joystick_IO;
 private Vector2 Touchpad_IO;


 private CharacterController cc;

 Vector3 move;

 void Start()
 {
     cc = GetComponent < CharacterController> ();
 }

 void Update(){



     Joystick_IO = Resources.Joystick.Joystick_Input ();      //takes input from another script


 

     cc.SimpleMove (Joystick_IO.x,0,Joystick_IO.y);     //apply it to character controller

 }

}

but it gives me initial glitch
