Accelerometer sensor in unity 3d?

Hope you all are doing good i am working on a game which needs both Input.mouse Position and tilting and i tried to use it with two different script but unfortunately i am having as issue my character vibrates on the z direction. i am writing both the codes below.

     public class conteoler : MonoBehaviour {

    public Camera cam;
    private float maxWidth;
    private bool camControl;

    // Use this for initialization
     void Start () {
     if (cam == null){
         cam = Camera.main;
     }
     camControl = false;
     Vector3  upperCorner = new Vector3(Screen.width, Screen.height, 0.0f);
     Vector3 targetWidth = cam.ScreenToWorldPoint (upperCorner);
     float hatWidth =  GetComponent<Renderer>().bounds.extents.x;
     maxWidth = targetWidth.x - hatWidth;
 }
 
 // Update is called once per frame
 void FixedUpdate () {
     if(camControl){
                     Vector3 rawPosition = cam.ScreenToWorldPoint (Input.mousePosition);
                     Vector3 targetPosition = new Vector3 (rawPosition.x, 0.0f, 0.0f);
                     float targetWidth = Mathf.Clamp (targetPosition.x, -maxWidth, maxWidth);
                     targetPosition = new Vector3(targetWidth,  targetPosition.y,  targetPosition.z);
                     GetComponent<Rigidbody2D>().MovePosition (targetPosition);
     }    
 }
 public void ToggleControl (bool toggle) {
     camControl =toggle;

 }

Second code.which i also put on the player.

     public class accelerometer : MonoBehaviour {
     private float speed = 10.0F;
     void Update() {
     Vector3 dir = Vector3.zero;
     dir.x = -Input.acceleration.y;
     dir.x = Input.acceleration.z;
     if (dir.sqrMagnitude > 50)
     dir.Normalize();
     dir *= Time.deltaTime;
     transform.Translate(dir * speed);
     }
