I fought all day looking for a way to trigger events which works in all browsers and systems. I was unexpected, but mousePressed() seems to not work in Safari in iOS if you define a doubleClicked() function.  
You could use mousePressed() but… In Android each touch in a button counts double…  
I share my solution here, may be is useful for someone.  
I simply block the second event in Android with avoiding consecutive clicks.

```auto
let lastclick;

function setup() {
   lastclick = 0;
}

function mousePressed() {
   if (500 < millis() - lastclick) {
      if (b1.contains(mouseX, mouseY)) {
         bp1 += 1;
         state += 1;
      } 
    lastclick = millis();
  }
}

```

I am testing this [here](https://rvalla.github.io/assets/testing/p5js/testing_ev.html).
