My white 32GB GS3 killed two cards. The first card was a Sandisk 32GB card, class 4. I used that card for 4-5 months before it died while having photos being written to it.
When that card died I switched to the 16GB class 2 card that came with my Droid X. The 16GB card performed perfectly for nearly 2 years before putting it in my GS3, and then it died after about 3 weeks.
I can't say that all GS3s kill SD cards, but mine sure did.
These problems, plus the awful battery life, will be pushing me back to an iPhone when my new every two is here in March 2014.
(My wife's iPhone 5, with LTE, wifi, and bluetooth radios on all day, with playing games and checking internet moderately, will have at least 75% battery left after being off the charger for 11-12 hours. It's incredible. And yes I realize iPhones do not have card slots for expansion).
