I haven`t experimented yet with C2 and mobiles, but as far as I know most mobile devices don`t support webGL and consequently no effects. There`s webGL support coming for CocoonJS that may enable them, and even then I think some effects may be too intensive for mobile, but I`m not sure that`s the case.
Overall there`s not much I can do. Maybe you could try asking in the general forums how to make webGL work on mobiles, as I`m not much into this area.
