So I have an off-brand tablet, the brand and model number are AGPteK TP714AQ. It is a very nice tablet for the price I paid and for being an off-brand, I have had no problems until now. So the problem is this: I have a 16GB SD card that when I connect it to my PC I can see it has only around 900MB used and around 13GB of free space. When it's in my tablet and I try to move apps to it i get the message: "Could not move app, not enough storage space on SD card" Why can't my tablet recognize that my SD card has a lot of free space on it? Any help is much appreciated, thanks.
