bought the card in January 2014. Since only used in my Samsung Galaxy. In March 2015 began to spin on my phone, crashes and freezes after using the camera. Made out map, phone running perfectly. So map "examined". Formatting is no longer and what is on the card can no longer Delete, write-protection would be activated. Tried everything possible. Card will not let me serve up my data. Too bad that the card has not kept, she was quick yes. Let's see how long the holding of Samsung.
