[AC Question]

SD card will not even show its in the phone. When I turn the phone back on. It seems like it is a dead card. But even dead cards show it is in the phone

Welcome to Android Central! Actually, dead cards often don't register. Try removing the card and inserting it into your computer's SD reader (using a fullsize SD adapter)--does the computer detect it? If not, there's not much you can do besides throw it in the trash.
