Bluescreen on phone

Hey guys. I want to create game on Android and when I put this script to the Main camera and start a game I can play, maybe a 10-15 seconds. After this time, displays a bluescreen.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class DestroyObjectesNormal : MonoBehaviour
{
   
   public static int myScoreNormal = 10;
   public static int myScoreKubekNormal = 5;
   
   public static int HighscoresNormal=0;
   
   public static bool isDeadNormal=false;
   
   
   public AudioClip shootSound;
   public AudioSource source;  
   
   public float volLowRange = .5f;
   public float volHighRange = 1.0f;         
   
   
   public void awake()
   {
     source = GetComponent<AudioSource>();
   }     
   
   
   /*void OnMouseDown()
   {
     isDead = true;
     Destroy (this.gameObject);
     Scoring ();
   }*/
   
   void Update() {
     
     RaycastHit hit;
     
     
     for (var i = 0; i < Input.touchCount; ++i) {
       Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch (i).position);
       if (Input.GetTouch (i).phase == TouchPhase.Began)
         
       if (Physics.Raycast (ray, out hit) && GameObject.FindGameObjectWithTag ("RollerBallNormal")) {
         Destroy (hit.transform.gameObject);
         ScoringHard();
         isDeadNormal = true;
         
       }
       if (Physics.Raycast (ray, out hit) && GameObject.FindGameObjectWithTag("KubekNormal")) {
         Destroy (hit.transform.gameObject);
         ScoringKubekHard();
         isDeadNormal = true;
         
       }
     }
     
     //if (Input.GetButtonDown ("Fire1")) {
     float vol = Random.Range (volLowRange, volHighRange);
     
     if (isDeadNormal == true) {
       //Scoring();
       
       source.PlayOneShot (shootSound);         
       isDeadNormal = false;     
     }
   }
   
   public void ScoringHard() {
     ScoreManagerNormal.scoreNormal += myScoreNormal;     
   }
   public void ScoringKubekHard () {
     ScoreManagerNormal.scoreNormal += myScoreNormal;     
   }
}

Your Awake function has a lower-case a, which I think means this function will not execute. (But this might be totally different.)
