Hi folks, I had bluetooth prep in my new S4. My existing Nokia works just fine but I've tried a few other phones and none of them work very well. They pair easy enough but have no real functionality. I know there are lots of threads on hear about cradles and the fact that the compatability list is small but does anyone know why bluetooth > bluetooth many of the phones don't work well? I'm asking this question with no real care for compatible cradles. cheers.
