Folks,
I'm not sure if I titled that right! Because I certainly would not try this on ANY Android phone. Certainly not a Samsung Galaxy Grand or LG K7 for example or ANY lower end Android. There are several prerequisites for this to work. Must be 7.0 OS, must have root, need to probably sideload daydream and Google VR services, need to install root explorer app. Also the process itself is a bit technical, HOWEVER if you can follow instructions you can most likely do it. I would NOT try this unless your phone is close to the Daydream specs. I MIGHT try it on my Mate 9, which did not make the cut due to it's LCD screen, BUT otherwise has the specs. I'm trying to decide if I want to root or not.
Anyways the instructions are in
this blog by VRHeads' Edition Russell Holly.

Thanks Russell!
