Hey,
The problem was installing an arm64 app on an armv7 device that’s why it didn’t show up.
It seems that developing 32bits apps for VR doesn’t really harm the performance so I chose to deploy my app to armv7 ( 32 bits ) instead of arm64 ( 64 bits ) and it did package and install successfully on the galaxy note 4.
Sorry for the late reply and thanks for your support !
