Can anyone explain me why window width at orientation angle 0 is 640 and at angle 90 it is 360 for android device?

Question

window.addEventListener("orientationchange", function(){
console.log("the orientation of the device is now " + screen.orientation.angle+"and width is"+this.innerWidth);
});

Answer 1

The orientationchange event is triggered before the screen size changes.

You can get the correct output using onresize or setting a timeOut in your orientationchange function to wait for screen resizing.
