Script in Camera turning objects white

Hi guys, Today I was testing my project on an Android device and I noticed that all objects turn white on screen. That problem wasn't happening in the editor. So after some tests I removed the script that was in the MainCamera and the problem disappeared.

Here is a screenshot of the android device (Sony Xperia Z2):

And here is the camera script:

 using UnityEngine;
 using System.Collections;

 public class CameraFollowPlayer : MonoBehaviour {


     public GameObject target;
     Vector3 pos;

     
     void Start(){
     

         Camera.main.orthographic = true;
         Camera.main.transform.rotation = Quaternion.Euler(30, 45, 0);

         pos = target.transform.position;
     }


     void LateUpdate () {

         float distance = 1000;
         Vector3 cameraDistance = new Vector3 (-distance, distance, -distance);

         Camera.main.transform.position = Vector3.Lerp(transform.position, target.transform.position + cameraDistance, 1f * Time.deltaTime);
         Camera.main.transform.LookAt (target.transform);


     
     }
 }

So I wanted to know what is causing the problem in the script. Thanks!
