In the future, more smartphone makers will consider shipping a virtual reality headset with their devices. LG is already doing that by giving new LG G3 customers a chance to experience virtual reality. VR for G3 works with Google Cardboard and allows G3 owners to experience VR compatible apps and games.
VR for G3 is based on the blueprint for Google Cardboard. It has a neodymium ring magnet on the side that works with the magnetic gyroscope sensor in the G3 to allow you to scroll through menus. Those who buy a LG G3 can also download a free VR game. You can find out more information here.
