I just purchased a Samsung Gear VR which I dock with my Samsung S7 edge. I downloaded a free VR game "Deep Space VR" from the Samsung Play Store on my S7. My question is... How do I play it. When I dock my phone into the VR headset, It automatically starts up with the Oculus home page and it's set of apps. I have been unable to figure out how to play a game I downloaded to my S7. Can it even be done? Does the app have to be downloaded to a specific directory. BTW, when I bought the Gear VR, the only thing in the box was the headset. There was no user manual. There seems to be very little information online as well. Anyway, I would appreciate any help on this subject. Thanks!
