Google Cardboard and Unity 5.4

Hi, I really cant figure out a way to make game for android google cardboard. Only thing I succesfully did was creating two cameras for each eyes by enabling virtual reality support from player settings. The camera didnt even moved while turning the phone. With unity 5.3 I was able to do that with official google cardboard plugin. Also the magnet button is a total mystery for me. Is there any tutorials yet for this? Or anybody wants to tell me how to do this ?
