I got mine on Amazon for like $55.
That could be a problem with the card. You could try backing it up to your computer then reformatting it.
Okay. So, I have a Sandisk Ultra 64gb Class 10 SDXC card tgat I want to use to replace the 32gb card I have in the Note 2 now. However, I've tried copying the 32gb card's contents to the 64gb one by connecting the 64gb card to the phone as USB Mass Storage, but it renames most of the folders and doesn't copy the files. I don't want to "move" the files because I don't want to risk losing them. After the 64gb card bas been successfully populated, then I will erase the 32gb card. BTW I have this same problem with my Galaxy Tab 2, . I did use this copying method successfuly on my Note 10.1.
My question is why isn't this working? (I currently don't have access to a working computer.)
Thanks.
