Hopefully this isn't a repost, but I was trying out USB OTG and realized that it could be used to transfer files from my GS3 to and from my other phones. I used a non-powered USB hub. It shows as 3 USB drives because one of my phones only has internal memory (no sd card installed). the other phone sees internal memory and SD card. As a bonus, the gs3 can be used to charge other phones.
