Last night i updated my S4 through the phone itself and after it was done it said that i had a blank sd card (ive had one in since i got the phone) and asked to format it and i selected yes. After a few seconds it would start to format and then go back to saying a blank memory card was inserted. I went into the settings and tried to mount the card but it was doing the same thing. I even tried formatting it in my computer and that wasnt even recognizing it...so i was wondering if this happened to anyone else and why did this update corrupt my memory card?
