In summary, this is a good friendly HUB to extend the capabilities of a Samsung, but also all devices that do not have direct USB OTG 2.0 port but the port (the one by which you charge your tablet usually). It connects everything that normally plugs into a USB 2.0 port elsewhere.
A reliable, and well worth recommending to extend the capabilities of your shelves.
