I purchased a 64 gb micro memory card recently. my previous card was so unorganized I figured id organize myself. currently my music and pics aren't getting read by my phone. any feedback to help me?

Tons of issues with SD cards and the S3

Are you running custom rom? stock rom? custom kernel? etc.

If you don't watch movies on the card - you can put it in your PC - backup all the data - and reformat it as Fat-32

Then you should have no issues

by default, the 64GB cards come formatted as exFat which has issues if using a custom rom and/or custom kernel combinations

LOTS of posts out there with this type of question

Simplest resolution is to reformat the card to Fat-32

fat32 formatting fixed the same issues for me as well!
