Are you not very tech savvy and just thought you got a good deal or what? Because if you were Tech Savvy, then you'd of already posted at least a paragraph long amount of what you already tried (most of which would've worked) and most likely would've of needed to post here.
As you can see here, in this link, it does, for a fact, have options in the Menu for SD Cards, as it supports up to 2 TB of an SD Card Expansion and it comes with Android 5.1 OS which is fairly new.
Honestly, dude, the definition of a Gamer is: "Pressing random buttons until something works." We don't use Instruction Manuals unless we're stuck. These same people usually become Tech Savvy because they realize how insanely easy it is to navigate the electronic world. So, start pressing random buttons until something works. It's, literally, that easy.
If you don't take risks, then you'll receive no reward.
