I do in fact connect the phone to the computer to transfer data, but it still fails. This is what I am referring to when I say, "transfer data through the USB cable."
But also, why should anything fail to support the card if the card is formatted in FAT32 from exfat? It is no longer an exfat card, but a 64 gig, FAT32, SD card which some claim works for them. Unfortunately, I am still forced to exclude myself from that list of happy customers.
