Hi, I've got a new phone, and I am desperately trying to connect to gear VR. Already install/ uninstall/install/uninstalled the Oculus app. The app is working on the S9, but when inserted to Gear VR, the screen goes black and so it stays. I've also waited, starting at the dark for a minute or two. The same device is working great on S6. What the !??! Please help!
