Code works in Unity5, Unity Remote 4, but not as in .APK

I have made a game to for Android. I’m not using any touch input, only void OnMouseDown, because, its only requires one click at the time.

What i am trying to do:
When i click on a object, a 2D Circle collider enables, and anyone within this collider shall be destroyed.

Where is it working?
When i test the game in unity, and click with the mouse it works perfectly
When i test the game though Unity Remote 4, with my Samsung Galaxy S6 egde, it works perfectly.

When i build the game into a .apk, and test it on my same Samsung mobile, it doesn’t work anymore.

Why would there be a different?

Last time I checked, my android didnt come with a mouse.

Does Android support OnMouseDown… not sure, but I doubt it. Your failed tests somewhat confirm it.

OnMouseDown have work so far.
I have only used OnMouseDown, to the whole game, It works perfect when i navigate though the menu and levels.
But when it comes to this object it wont work

Okay here is a how it was planned to work.

Object 1: The Bomb
Tag: Bomb
Collider: BoxCollider2D & CircleCollider2D (On trigger and disable at start)
Action: When you click on the bomb, CircleCollider2D enables

Object X: The Targets in plural
tag: unknown
Collider: BoxCollider2D
Action:

void OnTriggerEnter2D( Collider2D hit)
       
    {
        if (hit.gameObject.tag == "Bomb") 
           {
            Destroy (gameObject);
            }
        }
    }

Conclusion: Apperently the trigger function doesn’t work properly on my phone.
Solution: Instead of Trigger on 2D, i went back to the Bomb, Made this:

void OnTriggerEnter2D (Collider2D hit)
    {
        hit.gameObject.SendMessage ("destroy", SendMessageOptions.DontRequireReceiver);
    }

So every object who has a function destroy, will be destroyed.

I dont know if this is the perfect solution, but it works!
