Hi DonManfred, thanks for the reply and I will bow to your far superior knowledge of these things.
The reason I was looking into it is because you can get an app off the store that disables the Gear VR Service to enable cardboard VR to be viewed on the Samsung headset.
I could just buy their version but where's the fun in that...? Any idea how they could have achieved it? maybe using intents etc...?
Thanks
