iOSuserVR I'm not really sure I fully get what you are saying.
DeoVR doesn't create an Interactive folder on any device. We're aware you need root access on mobile phones. I just think the devs didn't think of that while porting the Oculus version to Cardboard and ios.
It's also our first implementation of this function because of popular demand. We plan on making it more user friendly with future updates.
DeoVR on iOS is actually even used less than on GearVR which isn't even officially supported anymore. We have DeoVR on ios simply because there is nothing else compatible with our interactive webUI on ios.
BTW can you, if you want to, use our other forum for stuff related only to that? DeoVR isn't age-restricted.
