Hello all! I am back to android from a very long hiatus. I am enjoying my new S7 to be sure but will take some getting used to. That said, I happily put in a brand new 64g sd card in preparation of filling it up with music, videos pictures all that. When I put it in, the phone said that it was corrupt and needed to be formatted. I tried using the format utility and it got to 20% and progressed no further. I am not able to use my sd card, can someone please point me in the right direction on how to solve this?
