Google Cardboard Magnetic Switch for OpenDive.

This will let you use the Google Cardboard app with a Dive headset.

Tested with the Durovis Dive and the Color-Cross/NEJE Headsets In my opinion the Color-Cross is much, much better than the Durovis provided you don’t have a very big nose.

It should work with other OpenDive type headsets. I only tested it with the LG-G3, some phones do not have sufficiently sensitive magnetometers to work with the Cardboard app. Unlike the paper Cardboard hardware with this you can fine tune the magnet placement.
