I don't have any issues with the sites on my phones/tablets...Android Kit-Kat, Firefox, Dolphin...and I post from my phone at work all the time. And it's not really even a decent Android device at that--it's a bleeding TRACFONE, basically a throw-away phone by today's standards. Forums and SEAM even worked from an old LG-800 series phone that was JAVA based, using UC browser. I've got MSIE "disabled" through DISM, running Firefox as I type this. The launcher uses the MSIE components of the OS... but otherwise, I'm not using Microsoft's browsing technology per se, and don't have any issues. Maybe something needs to be configured in your browser or something? Maybe your iphone is using the Beta (which SE announced last month there are issues with the 9 beta).
