I've had a lot of trouble finding an app that would load my 360 panoramas and display them in a Google Cardboard headset.
But Photosphere Viewer from Primitive Factory works well.
It is available in the Google Play and Apple app stores.
It will load and display a 360 panorama from the Lightwave VR camera.
It can display it on the phone's screen with navigation by swiping and can also display it in a Google Cardboard headset.
In the headset navigation is by turning your head and looking around.
Unfortunately, Photosphere Viewer has ads on the bottom of the screen but otherwise it is free and works.
The ads are not too obtrusive.
Two web examples of what I am trying to do on a phone :
The first is a basketball practice court in a former warehouse.
It was done with Lightwave 11.6 and Liberty3D Ubercam.

The second is a Grandstand proposal and was done with the Lightwave 2018 VR camera.

I have had to go up to a 6000 x 3000 size VR image to get the resolution in the phone to an acceptable point.
