So I got this 64 gig Samsung SD card. the card works great in my samsung and also is read just fine by PC. whenever I put it into either my phone or my friends who has the identical same phone I get card corrupted or not supported. I'm at a loss here does anybody have any suggestions?
With the lack of developer support this would be the final nail in the coffin for this phone in my opinion.
Anybody here successfully have a 64 gig card or bigger work properly?
