Great budget tablet
I am using this tablet for education purpose my model is 3d q45( 1+ 8) and it's working great
My tablet has Android 4.4 KitKat
The problem is that the internal storage is read only but you can't download in phone memory you have to download in sd card and after than you can send it to internal storage
The memory card capability is upto 32gb
It's dual sim tablet one port is for mini sim and other is for micro sim and the tablet also contains a antenna for FM radio
It's an awesome budget tablet
