GoogleVR Android Build - Only one camera

Hey!

I am trying to implement VR in my game for it to be playable with Google Cardboard. I used the (camera) prefab in the GoogleVR SDK, and it works fine when I play it in Unity, and then using Unity Remote 4.

However, when building to my Galaxy S6, it looks like there is only one camera, split in two (but the separated view and distortion are correct). I tried building the DemoScene in the GoogleVR SDK and the same problem arises, same using another Android phone.

Also, in the player settings, I left "Virtual Reality Supported" unchecked, because otherwise it prompts Gear VR, which is not my intention.

So what do you think is happening? Thanks!
