Maybe I got a defective card but this one felt a bit &#34;thinner&#34; and &#34;flimsier&#34; than other micro-SD cards I've had.The real problem was after a week of use as expanded storage in a tablet, I started having trouble with certain programs installed on the card, then finally the tablet gave me a message that the card was corrupt, and while a PC would recognize it, eery time I tried to format the card, there would be an error.
