So i was given the Gear VR headset for Christmas, but it seems I can only use it for roughly 10 mins. before I get the message on the screen that the phone needs to cool down, and to disconnect it from the headset. My bf has the same phone and headset and can be on it for hours with no problems. I did some research and found a lot of stories of the Oculus app. causing the issue (along with battery draining), and instructs to uninstall and allow it to re-install the latest version of it, however that didn't work. Do I HAVE to have the Oculus app installed in order to use the Gear? I'd hate to have to return it, but I might have to if I can't get to the bottom of this. Also, I did make sure that all other apps were closed.
