Bought this with my Samsung Galaxy S4 when it first came onto market and it worked for about a week then quit. All of the pictures I had taken originally and stored on this card are just gone, it was a bad purchase and after looking through numerous forums, hundreds or thousands of people were having the same issues with this card and the Galaxy S3 + 4, I do not recommend buying this card if you'll be putting it in a galaxy. I'd like to tell sandisk where they can put it.
