Bought this for Galaxy S3, worked like a charm for 3 months & then I started getting error messages on phone stating the card has been taken out or that it is not there, went on like this for a week or so & then one day gone. Initially I thought it was problem with phone. Popped in a 2Gb card from BB & it worked. Popped this one into the BB & same, no detection. After spending so much on an SD card its disappointing to see it go bust outside of return period.
