I'm having a heck of a time mounting a new micro SD card on my Kyocera Rise. I have not yet rooted the phone and I don't really plan to if it's not necessary. The new card is a Sandisk 16 GB class 4 micro SD HC. It is formatted for FAT 32. I copied all the files from the original 2 GB card onto it, and put it into the SD card slot underneath the battery. When I tap "Mount SD card" the phone says "Preparing SD card" then says "SD card safe to remove." It seems like the phone isn't seeing the new card at all. What am I doing wrong?
