I’m having some issues building my app for Gear VR S6, here are the details :
http://forum.unity3d.com/threads/samsung-gear-vr-s6-grey-screen-on-unity-5-1-2-build.354076/

I just want to know if I absolutely have to build using “Build and Run” or if “Build” is fine.
Note that I never used “Build and Run” to build my previous android apps and it worked so far.

Thanks by advance.

All “Build and Run” does is first builds the game, and then attempts to copy it to and run it on the device. If you just click “Build” you’ll get the compiled executable on your computer. Then manually copy it and execute it on the device you’ve achieved exactly the same.
