I'm on the road a lot for work and have recently bought my first Daydream VR and been enjoying watching films and series using SKYBOX VR Video Player.
However because of available limited resources on my phone and sd card i regularly use a USB storage device to store and access large (mainly media) files on my phone.
I noticed that SKYBOX only supports browsing through the phone's internal storage and sd card and lacks the USB mass storage device when it's connected.
I think adding support for this feature will increase the value of the product considerably because it'll allow users to bring high resolution VR videos with them without having to worry about storage capacity on their phones themselfs
