I had checked keep phone off in a dark place such as a pocket or bag. Every time that I hooked my phone up to my Samsung VR I would receive a notice "remove receiver and turn on phone". I could not figure out why this kept occurring as the phone was definitely on when I attached it to my VR. I then removed turn off in a dark place and that resolved my problem. Others may have figured this out but it took me a while to figure out my problem.
