Camera not moving on mobile

Hi!

I'm making a simple 2D game with Unity, nothing really hard to code, but I have a problem with moving the camera en mobile devices (in the editor it's working just fine!).

Here's the script that move the camera (custom smooth follow script. It's following the player and the damping variable is set to 10).

(pastebin to the code because the code sample thing looks quite broken: http://pastebin.com/hPkRs56k

  using UnityEngine;

  using System.Collections;

  public class SmoothFollow : MonoBehaviour {

      public Transform target;    // The target we are following

      public float positionDamping;

      private Vector3 deltaPos;

      // Use this for initialization

      void Start () {

          deltaPos = new Vector3(-4f, 1f, 0f);

      }

      // Update is called once per frame

      void Update () {

      }

      public void FixedUpdate () { 

          Vector3 targetPosition = target.position - (Vector3.forward *

10);

          Camera.main.transform.position = Vector3.Lerp(Camera.main.transform.position, targetPosition + deltaPos,

positionDamping * Time.deltaTime);
} }
