When I swipe to scroll in the browser, I sometimes get a momentum effect, so with a fast flick of my finger the scroll continues for some time afterwards. This is great, and has been a major element of touch UI design for quite some time.
But I only get it sometimes. On the same page it might scroll nicely one swipe, then “jam” for the next ten, stopping immediately my finger leaves the screen.
Momentum scrolling seems to work well elsewhere (e.g. all contacts list), but not in browsers.
Is this normal? If not, any suggestions for a fix?
