I just bought last week a Samsung Gear VR (Consumer Edition $99) and read a lot about using it as a FPV headset. The problem is that as soon as you place your phone on the VR, the Oculus app activates. I have a rooted Note 5, I turned off the Gear VR Service app, that way I can launch Litchi on Cardboard (VR) mode. The problem I was having is, I would loose the ability to click, or deal with the interface after wearing the headset, but, with a cheap Bluetooth mouse, linked to my Note, I have complete access to the Litchi interface!!! Will be flying it and recording screen next week. Stay tuned if you are interested in VR capabilities.
