Unsupported sd cardUnsupported sd card, no sd card


"Today I finally had time to work on moving my media from my old 32 GB card that I had in my Galaxy S4 to the new 64 GB card that came with my Galaxy S7 Edge. I got the phone/card/VR device all on release day at Best Buy. When I put the card in the phone, it says it's an unsupported card, touch to set up in a supported format. So I do, and on the next screen I touch Format, and it appears that it's doing what it should. But then I get an error message, which says the sd cannot be formatted." --- from J_rae_p on
