this is the tablet I use, it has a usb and a micro usb like I mentioned. I'm not sure how a galaxy s6 works, I have a galaxy s5 and the s5 uses a different type of connector on the phone side, other side is just standard usb.

I used the adapter for a while until I bought a usb extender and added 4 usb spots. it's handy to have a mouse and keyboard with the tablet because I can't tap that thing to save my life.
