I was unable to use my microSD in my tablet. It seemed to recognise it at first, since it immediately wrote the lost.dir file to it, and I could create a folder on it. But I could not delete or rename that same folder as soon as I had created it; nor could I move or paste files into it. A friend suggested to format the card in exFAT and it seems to work fine now. Anybody with the same problem give it a try. Does anybody have an opinion why FAT32 wouldn't work for me?
