    I recently had a problem with a Sandisk 32gb card in my S4 where it started unmounting and remounting itself at random. Posted a thread here and someone said it is a known issue with the card itself. So, I ended up buying a different 32gb card, a Samsung 32gb, and it works just fine with no issues. I don't know if this is related to your issue or not.
    I just purchased a Samsung UHS-I 32g class 10 today so im awaiting its arrival. I will post and update as soon as i receive it.

    The latest very large "update" via ATT has fixed this issue. No more "damaged sdcard" causing unmounted cards!
    My 64gb Kingston is working without any issues now.

    According to Sandisk support when I talked to them around June, 2013, and all over the Amazon reviews for months, is a known incompatibility between the Sandisk Ultra Micro SD cards (possibly others), and the Galaxy phones (possibly others). The card can "fail" any time from days to many months down the road. Sandisk says that Samsung won't admit it, and so Sandisk created a ROM patch that is applied only during manufacturing, to circumvent the problem.

    Contact Sandisk for free replacement. I was told that the new card batch started after March, 2013, but the only way to tell, is based on a small serial number on the card, that requires a magnifying glass, if you can even then read it.

    I do not know if other cards from other mfgs are involved, but Sandisk says they have stepped in and solved it on theirs. Good luck!

    I found, on the Sandisk web site, that they have "Android" and "non Android" microsd cards. The following is shown for 32G cards:
    Memory Card with Adapter - Android
    Europe/Asia-Pacific/Latin America/Middle East & Africa
    SDSDQUA-032G-U46A - 32GB

    Memory Card with Adapter - non Android
    Europe/Asia-Pacific/Latin America/Middle East & Africa
    SDSDQU-032G-U46A - 32GB
