On my Samsung Galaxy S3, my new SanDisk Ultra 64GB microSDXC Class 10 UHS-1 card intermittently produces an “Empty” when I browse it using both Solid Explorer and Root Explorer. Other times it shows, and my music player plays, all the files I’ve transferred from my computer.
I’ve reformatted the card in the phone (more than once). Files have been transferred from a Windows XP PC, inserting the card in the supplied adapter, inserted in turn in a Transcend USB plug-in.
The only “solution,” so far, is to remove the card (after unmounting) from the phone and then reinserting. Sometimes, I have to shut down the phone and restart it.
Is this a (known) problem with the card? something else?
