I want to use this component to add a mobile experience to the responsive themes created by Yootheme, but it absolutely does not work at all. I've asked yootheme about it, and they told me that Joomla decides which template to show, and your component does not handle the switching correctly.
True!
MobileJoomla works well with most of responsive templates. Just note that in the case of responsive template, "Template" fields on MJ settings page should be set to empty value, and "Template Modules/Template Options" parameters are not applicable in this case.
