Is there any way to detect the "back" click? More necessarily from mobile devices (Android is enough).

I would like, in my web app, the back button can call certain functions, in this case close popups. Do you have any idea?

You can try using the function:

document.addEventListener("backbutton", onBack, false)
function onBack(){ /* faz algo ao clicar no botão voltar */ }

didn’t work :( you already tested it?

I found a way!! but I’m not able to duplicate it to use more than one popup. I’ll put her link in jsfiddle, if you want to try it would be great!

and on your question, no mistake, just exit the web app without calling the function

all I need is that, like, the "share" button can be duplicated and each open a different popup and close their respective ones. when I tried this one of them always ends up losing the effect and I don’t understand why

Hello I made a fast way here, https://jsfiddle.net/3e5dgo0j/1/ see if that’s it, only missing when you click a exit, and you can slow down the effect tbm, I didn’t understand if that’s what you wanted.
