So, I recently got a Nexus 7 (32gb). Its working great and I have enjoyed using it. I bought it thinking there was no way of expanding it, but I recently learned about a OTG cable that can be used with the Nexus7 in its micro-USB/charging port. From the way I understand it, I would then be able to use a USB thumb drive to play additional content.
What other uses can be used with an OTG cable? Is any kind of rooting needed in order to use it? If not, what app is needed to make it work best? Is there maybe a good website that has some info ALL about using the OTG with the Nexus 7?
