Hi I hope someone can help. I have an Allwinner A13 7 inch tablet running Android 4.1 jellybean. I have added an 8gb sd card. When i go into storage options the card is mounted correctly. There appears to be 3 storage devices in the list (see pictures)! It will not allow me to store anything to it even when i download apps to the sd card it seems to go to internal storage (which is also listed as SD card!) The one that i assume is tablets own internal storage comes up as SD card but only has 2gb available. The 8gb SD card shows up but is empty. I have tried 3 different SD cards and always get this problem. (All 3 are listed as internal memory) As a result I am constantly getting error message, like "insufficient storage space" and "process has stopped" etc. I have also tried the apps from google play to move apps to sd card and it doesn't seem to work either! I have formatted the SD card via my laptop and my tablet is meant to be compatible up to 32gb. I have added a screen dump in the hope that someone can understand what the problem is. Please can anyone help me. I hope this makes sense it is quite hard to explain!
