Like so many others, I too am getting the "sd card is blank or has unsupported filesystem" error. I have formatted the card multiple times using both my Galaxy s4 phone and PC... on the PC using both the quick and... not so quick formatting operations. I have successfully written files to the sd card on my PC. That suggests t me that the card was successfully formatted and is capable of being written to. I still get the"sd card is blank or has unsupported filesystem" error when placing the card into my Galaxy s4 phone. Is this phone capable of handling a 32GB card? If so what else could be wrong? Thanks in advance!
