Hi, I need some help. I have a 16 gb card in my galaxy S2 phone full of pics, videos & music. I just got a galaxy tab pro & bought a 32 gb card at same time. I would like to transfer all my music from the 16gb card to the 32gb card & then use the 32 gb card in the S2 (since I like having my music portable & take pics with the phone) & put the 16gb card in my pro. What's the simplest way to do this? I don't have a pc, but I have wifi (if that'd be any help). Thanks.
