Unfortunately this is not true. I've been researching the heck out of this issue due to ongoing problems. It seems all cards are susceptible to this problem in the GS4. I'm awaiting my replacement from sandisk as we speak.
My issues: card worked for awhile. Then when unlocking phone it would give me messages about unmounting then preparing SD card. A few days after that it would say it was damaged. After a week the problems stopped for a month, then came back. Now the card is completely dead and /if/ I can get windows to recognize it, it says it needs to format it but it cant.
Other users reported similar things and a few reported same issues with Samsung cards.
