The new card has problems beyond a filling of about 52%: the card is blocked and you should remove it and return (on a PC) or redémmarer the smartphone so that it works again ... So This is a 32 GB for the price of a 64GB ...
Two defective cards away, it starts to do much ... the series should have problems ... then WARNING!
