not working on samsung mobile

Hi
I just tried to work with this theme for my blog, and it seemed fine, with great speed in gtmetrix; and easily readable as I like

But, when I tried the theme on my old sansung ace (android) mobile, the theme did not work at all. The main page was not shown and I could only see the first widget in the sidebar. When I tried to scroll down, it just got stuck…

Does it happen with all mobiles or is it just with mine?

I also tried Scott blog on my mobile and the same problem happened…

Thanks in advance
