If the TFcard can not be recognized by your phone,please use a paper or nail to wipe the TF card and the card slot. Sometimes it is just a problem of connection.
Please also check whether you have plugged the card in the right way, please pay attention to the direction when you insert it.
Try other TF card to check what the problem is.
