i use V 4.5. I create a button in my game. When i click button I want to my game full screen in mobile. But when i click button, my  console say : "Failed to execute 'requestFullscreen' on 'Element': API can only be initiated by a user gesture."

that.btnSpin.on("pointerover", that.btnOver).on("pointerout", that.btnOut).on("pointerdown", that.btnSpinDown).on("touchstart", checkFullScreen).on("click", checkFullScreen).on("mousedown", checkFullScreen).on("tab", checkFullScreen);


var checkFullScreen = function () {
			document.documentElement.requestFullscreen ? document.documentElement.requestFullscreen() : document.documentElement.msRequestFullscreen ? document.documentElement.msRequestFullscreen() : document.documentElement.mozRequestFullScreen ? document.documentElement.mozRequestFullScreen() : document.documentElement.webkitRequestFullscreen && document.documentElement.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);

For mobile devices, some of those events above are not classes as valid events to unlock audio or unlock full screen API. touchstart or touchend is usually what you need

just add some in-game button to toggle fullscreen request and you should be fine.

"pointerup" worked fine for me with 4.7, "pointerdown" didn't trigger a user event in chrome-android back then.

The interaction has to be complete, a touchdown is not a complete interaction but touchup is.
