    You know how in Android the back button is sometimes not a back button? It sometimes transforms to a close button (modal, image overlay, keyboard, etc.)

    With an app built for iOS, these “close on back” was not working

      As a web app, such behaviour will also need to be programmed to work on a browser first. Packaging it for Play Store should not grant that behaviour automatically.

      (2) Image overlay For Voyager, back button for image overlay works in browser.

      When opening an image viewer, the web app triggers a browser history change like this:

      1. Browsing on feed - https://vger.app/posts/lemmy.world/all
      2. Opening an image viewer - https://vger.app/posts/lemmy.world/all#galleryOpen

      ^ notice the extra #galleryOpen

      When back button is triggered, the web page will listen to a “back” event, and close the image viewer.

      (3) Keyboard: Keyboard is a native UI. So triggering “back” will always close the keyboard

      (1) Modal / bottom sheet

      But… I couldn’t figure out this one yet

      Clicking on the “3 dots icon” in a post opens a bottom sheet interface.

      Play Store version response to back button properly. But the web app version does not.
