I'm not much help with phones, moderation via phone is dangerous at best (to say nothing of admin functions) so I stick mostly to devices with keyboards and mice.

On phones you normally have a choice between mobile version or traditional browser version, try that.

You might also try a different skin, there are several versions...
USER CP/Settings & Options/Edit Options => scroll to the bottom, and try a different forum skin.

Also they are doing a major update this afternoon, that may possibly change or improve things, or make new skins available.
