Function in Awake() does not execute on mobile android device?

I've written a code that generates a lines of string from a .Json file onto a panel with a button component when the panel is clicked. Once the scene is loaded the text is supposed to be displayed onto the panel automatically, so i used :

 public void Awake()
     {
         nextQuestion = true;
         OnClick();
     }

 public void OnClick(){
 QuestionBegin();
 int randomIndex = Random.Range(0, questionsData["quiz"].Count);
 
             GameObject.Find("Screen/QuestionPanel/Quest").GetComponentInChildren<Text>().text = questionsData["quiz"][randomIndex]["question"].ToString();
             GameObject.Find("Category/Text").GetComponentInChildren<Text>().text = questionsData["quiz"][randomIndex]["category"].ToString();
             GameObject.Find("QuestNum").GetComponentInChildren<Text>().text = "Questions " + numberQuestions.ToString()+"/120";
 nextQuestion = false;
             clickAnswer = true;
         }
     }
 
 <LengthyFunction>(){
 .....
 .....
 .....
 nextQuestion = true;
             clickAnswer = false;
      }
    }
 }

It works smoothly on the game and unity remote, but when I build the apk and run it in android the OnClick() function does not start and this is a problem. Is there something in the unity settings that I missed or does onclick not work on mobile or is it something completely different?
