Which browser are you using? Not that is should matter because it should display fine any any browser. Depending on the browser, how the page is viewed can be adjusted in your browsers options settings. You can also change the style the forum serves you by clicking here and selecting an option. You can always change the theme by clicking the theme name in the bottom left area of any page.
To tell you the truth I have no idea which browser my android uses, but it always worked fine. It looks like the default theme may work ok although I don't like it a much as the other one.
