collision 2D not working on android device

hello everyone i'm working on a 2D android shooting game with unity 5.4 now to display some buttons that means that the game is over, i used OnCollisionEnter2D to detect if the bullet collides with a gameobject and then set the button canvas to active and timescale to 0 to stope the game

here is the code i used :

 void OnCollisionEnter2D(Collision2D col) {
                 if (col.gameObject.tag == "poop"){
                         Destroy (col.gameObject);
                         Time.timeScale = 0;
 
 
                         foreach ( Canvas button in buttons )
                         {
                                 button.gameObject.SetActive (true);
                         }
                 }
         }

the probleme is that this works fine in the emulator but when i build the apk and install in my android device, it does not work

any help, please ???!!!`enter code here`

"does not work" is not a helpful problem description. What did you expect to happen? What actually happened?

the idea is when the 2 object collide this will set some buttons to active, in fact is the game over lenu when they collide the game stops and the menu take place

so in unity emulator, it works but in device it does not, i see it colliding but the menu does not appear

thank you

The menu does not appear..... but the colliding gameobject gets destroyed and the timescale gets set to 0, right? So where do you assign the buttons array? Why do you set timescale to 0 anyway? There are a ton of problems I see with people trying to use that, since it stops the game update loop from running.

no the gameobject does not get destroyed and the time scale dont doesnt change but in the device i see the gameobject collide with the other game object because i see the gameobject stops moving

i forgot to mention this

i added : " public Canvas[] buttons; "
