Move forward camera using mobile inclination

Hi. I am creating a game in virtual reality from Unity. The problem is that I want the camera to advance when the user tilt the cell x degrees. That is, the viewfinder camera advances in the direction of inclination. I have seen that some people occupy the character controller, but when I tilt the cell phone, the camera does not advance. Could someone help me with this? This is the main code:

I'm not using any specific library, I'm just taking "build and run" directly on my android device.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.UI;
 using UnityEngine;
 
 public class Movecharacter : MonoBehaviour {
     
     public Transform vrCamera;
     public float toogleAngle=30.0f;
     public float speed=3.0f;
     public bool moveForward;
 
     public  Quaternion rotation;
 
     private CharacterController cc;
 
     void Start () {
         Input.gyro.enabled = true; //
         cc = GetComponent<CharacterController> ();
     }
     
     void Update () {
         Vector3 forward = vrCamera.TransformDirection (Vector3.forward);
         rotation = new Quaternion(0.5f, 0.5f, -0.5f, 0.5f) * Input.gyro.attitude * new Quaternion(0, 0, 1, 0);
         if (posiciones.x < -0.25f) {
             moveForward = true;
         } else {
             moveForward = false;
         }
         if (moveForward) {
             Vector3 forward = vrCamera.TransformDirection (Vector3.forward);
             cc.SimpleMove (forward * speed);
         }
     }
 }
