ionScroll event doesn't work properly on android emulator


I am using ionScroll to detect scroll events of the main content. In a web browser it works as expected: it shoots every couple of pixels. But on an emulator (I don’t have a device yet), the event shoots only when the scroll ends. Can anyone advice? Also, the velocity parameters are always 0 both on the browser, and the emulator :-/

this.content.ionScroll.subscribe((scrollEvent: ScrollEvent) => { => { this.onContentScroll(scrollEvent); }); });
