please integrate cardboard EU4 . On cardboard you can use the smarthphones compatibility with Leap Motion , and the gear used vr galaxy s4 and s6, and is not compatible with the Leap Motion . Leap Motion + vr + EU4 would be great , it may be possible to smartphones with snapdragons. Agree with google to give them the android sdk Cardboard well as they did with Gear vr. I develop video games for mobile devices and I would like to apply to vr for mobile. Gear vr niche with its kit is exclusive only for users of the S4 and S6
