Dell Venue 7 SD Card Not Working

Recently I bought a dell venue 7 16GB. And also i got a brand new micro sd card for it. Since im new to android i thought that when my internal memory runs out the OS well start moving stuff to the sd card, but it didnt so i tried to do it manually. I looked at some tutorials on how to do it and all said that you should have a "move to sd card" feature when you go to settings>apps and choose an app you want to move to sd card. But the "move to sd card" was not there so i looked at some other tutorials for 4.2.2 JB android and some tutorials said u need an app to do it so i got "app 2 sd" and that did not work it gave me an error saying " The device does not have a real primary external storage, or the primary external storage is emulated" confused i went to techage and followed the tutorial there and it still did not work! So can someone tell me how i can get "move to sd card" or is my tablet broken or is the SD cards fault?

THANKS!
