Back and forth between touchscreen & mobile VR

Hello all
I am building to mobile (using latest 5.6) and want to go back and forth between touchscreen app and VR (only cardboard & daydream) on either android or iOS.
I want people to be able to press a button and go back and forth - slipping their phone in and out of a viewer.
( I’m going to ignore Gear for right now as it’s its own thing)

In the documentation there say to use :
VRSettings.LoadDeviceByName

With ‘None’ listed in the build settings

Any Ideas?

Thanks

I could tell you, but then I’d have to kill you…
