Initially, the card went well, after about 12 months, she was partly no longer recognized. The tablet was also rarely benutzt.Ein restart helped but then again with my Galaxy Tab 3. After 15 months she was no longer recognized, and on the PC does not. Formatting / Partitioning also does not work anymore. Card is completely dead, and all data is gone !! Verbatim I expected more! When I read the reviews here have the more the problem, you can not recommend this card!
