Hi, I'm trying to transfer files from my tabs internal memory to the external sd card. I went to the my files app & I am copying and pasting to the ext card but it keeps saying access denied. It also says this when I try to create a folder on the sd card. The tab recognises the sd card & it 64gb space, so am not sure where I'm going wrong. I bought this card of ebay, think I've been sold a dodgy one 🙁
