My SGS3 is recognised -- but it does not connect or transfer files, not even a backup!
I have tried everything from numerous cables to different PCs & even a Mac (because I'm a Mac user). I've used a PC to satisfy myself that it's not my Mac and nothing has worked.
Any suggestions? Should I contact samsung and say "Give me a new one"? But what good is that when all my files photos and music are on this that won't back up!!
