Having GameObject follow phone's gyro

I've been trying to have a gameobject be controlled by my phone - however, when I actually implement the code, the object, when facing up for example, will change its z rotation while I'm changing the phone's y rotation - however, because my phone is facing up, it reads the change as z. How can I have a local rotation from my phones gyro like I have a local rotation for the actual object? using UnityEngine; using System.Collections;

 public class positionmang : MonoBehaviour {
     public float speed;
     private float step;
     void Start() {
         Input.gyro.enabled = true;
     }
     void Update() {
         step = speed * Time.deltaTime;
         Quaternion phoneRotation = new Quaternion (Input.gyro.attitude [0], Input.gyro.attitude [2], Input.gyro.attitude [1], Input.gyro.attitude [3]);
         transform.localRotation = Quaternion.RotateTowards (transform.localRotation, phoneRotation, step);
     }
 }
