Joystick movement works on editor but not on mobile

Question

I want to make a joystick controller for movement I created 2 script for this player move and joystick script, but I have a problem joystick movement works perfectly on editor but on mobile it's not working, joystick is still working but my character is not moving

Here's my script:

player move:

    using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class PlayerMoveController : MonoBehaviour
{
    public GameObject player;
    private CharacterController _charController;
    private float inputX;
    private Transform meshPlayer;
    private float inputZ;
    private Vector3 v_movement;
    private float moveSpeed;
    public ManagerJoystick _mngrJoystick;




    // Start is called before the first frame update
    void Start()
    {
        moveSpeed = 1;
        meshPlayer = player.transform.GetChild(0);
        GameObject tempPlayer = GameObject.FindGameObjectWithTag("Player");
        _charController = player.GetComponent<CharacterController>();
        _charController = tempPlayer.GetComponent<CharacterController>();
    }

    void Update()
    {
        inputX = _mngrJoystick.inputHorizontal();
        inputZ = _mngrJoystick.inputVertical();
    }

    void FixedUpdate()
    {
        v_movement = new Vector3(inputX * moveSpeed, 0, inputZ * moveSpeed);
        _charController.Move(v_movement);
    }

}

joystick controller:

    public class ManagerJoystick : MonoBehaviour, IDragHandler, IPointerDownHandler, IPointerUpHandler
{
    private Image imgJoystickBg;
    private Image imgJoystick;
    private Vector2 posInput;

    private void Start()
    {
        imgJoystickBg = GetComponent<Image>();
        imgJoystick = transform.GetChild(0).GetComponent<Image>();
    }

    public void OnDrag(PointerEventData eventData)
    {
        if (RectTransformUtility.ScreenPointToLocalPointInRectangle(
            imgJoystickBg.rectTransform,
            eventData.position,
            eventData.pressEventCamera,
            out posInput))
        {
            posInput.x = posInput.x / (imgJoystickBg.rectTransform.sizeDelta.x);
            posInput.y = posInput.y / (imgJoystickBg.rectTransform.sizeDelta.y);
            Debug.Log(posInput.x.ToString());

            //normalize
            if (posInput.magnitude > 1.0f)
            {
                posInput = posInput.normalized;
            }
    
            //joystick move

            imgJoystick.rectTransform.anchoredPosition = new Vector2(
                posInput.x * (imgJoystickBg.rectTransform.sizeDelta.x) / 4,
                posInput.y * (imgJoystickBg.rectTransform.sizeDelta.y) / 4);

        }
    }

    public void OnPointerDown(PointerEventData eventData)
    {
        OnDrag(eventData);
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        posInput = Vector2.zero;
        imgJoystick.rectTransform.anchoredPosition = Vector2.zero;
    }

    public float inputHorizontal()
    {
        if (posInput.x != 0)
            return posInput.x;
        else
            return Input.GetAxis("Horizontal");

    }
        
    public float inputVertical()
    {
        if (posInput.x != 0)
            return posInput.y;
        else
            return Input.GetAxis("Vertical");
    }    
}
