Basically that's what UE4 Gear VR app is asking for upon fresh install:
Is that something that Oculus/Epic require?
If not, how do I disable those (except maybe modifying SD card content) ? I personally don't like when apps ask me for a ton of permissions (like accessing my contacts, location, my SSN, etc. :wink: )
UE4 needs /sdcard as it stores a lot of app-independent stuff there, like the UE4 .so file, in order to share files between apps and not have too high of a memory footprint IIRC.
