So we know officially the S3 supports 64GB cards. With that out of the way i can tell you mine has some quirks. It recognizes the card, sees the capacity, and writes to it with no issues.
HOWEVER, on the device and in explorer it doesn't show all the data. For instance all my music albums stop at the letter 'J' - I am not able to create new folders from the phone or with explorer while tethered.
It does not see it all the data in Kies either. Air or tethered. In fact Kies locks up with spinning timer in the Photo and Music boxes. But if you take out the card and plug it into a card reader it sees everything fine and you can add and delete folders.
It is a SanDisk Ultra class 10 ($64 on Amazon - Prime eligible) I'm stumped.
