Swiping works on desktop but not on mobile

Hallo,
today I started checking my pages on my new mobile (Samsung Ace 3). One problem I encountered was that swiping pages works on my desktop computer but not on my mobile, e. g. on this page:

Resizing the images and the video for responsive behaviour works fine, thus javascript seems to be activated. The buttons for paging are also working fine. Any ideas what's the problem and how I can fix it?
Best regards - Ulrich
