Yes indeed, when you install your Samsung Galaxy S6 or S7 in the Samsung Gear VR headset, a default application (Oculus store) is launched, preventing you from viewing your pano. To disable this feature, you must install a package disabler from the play store. Search for “package disabler”, install Package Disable Pro (will cost you 1,2 €), launch the app and disable the “Gear VR service”. That’s it. You can now plug your S6 or S7 into the Gear VR without Oculus Home interfering.
