I'm really into mods, but as I said, on the phone it's just too much of a hassle. I'm not sure about iPhone, but on Android you can buy EE from the play store.
About companions interaction, it seems like every time you finish some big quest (and there are many of those in bg2) all the companions get triggered and start talking to me one after the other. As I said, no mods this time around so I don't think it's the problem
