Unity 5 - Playerprefs saving in unity but not on android?

Question

I have this attached to my hero object that gets destroyed . Could that be part of the problem? All I want to do is save the highscore then display it on my start scene. Here is the code:

public int highscore; 
public int score;   


void AddPoint1()
{


    if (score > highscore) {
        highscore = score;
        PlayerPrefs.SetInt ("highscore", score);
        PlayerPrefs.Save ();

    }
}

Here is second script attached to empty object in start scene (different scene)

void OnGUI()
{ 
    GUI.Label (new Rect (Screen.width / 2, Screen.height/2, 100, 100), "Highscore: " + PlayerPrefs.GetInt("highscore"), customGuistyle);
}

Answer 1

From my knowledge of Unity you do not need to call PlayerPrefs.Save(), also I've noticed that you have the highscore stored locally and it is never defined, therefore you are comparing the score to a null value. Your new code would look like this:

public int score; 
void AddPoint1()
{
     if(score > PlayerPrefs.GetInt("highscore"))
     {
           PlayerPrefs.SetInt("highscore", score);
     }
}

Also even if you initially set highscore to something, say 1. The code would work but as soon as you close the application and rerun it the highscore would be reset back to one, and then even if the player scored 2, it would override the PlayerPrefs highscore no matter what it is.
