I have some compatibility issues with my Galaxy Note 2 (4.1.1). In the PC web browser, device info shows I have internal memory and SD card, but my 64GB SD card is listed as 10GB which is wrong. In the file manager on both the PC and app show only 1 drive (SD Card 0) which is actually my internal memory, and does not show 64GB SD card at all. So I cannot copy files to or from device.
