good at the beginning but then .....

Memory was used in a Samsung smartphone and stayed there. After a year of Smartphine reports the unexpected removal of the memory card, then at some point the memory is supposedly empty but you can after all nothing more write it (even though she was not previously fully). Test on a Netbokk shows no memory. Eventually, she was recognized again in Smartphone ..... for one week, then the same game. Crap!
