The big question is why it works like a charm for some people and not at all for others? Could there be any difference in the hardware between batches since the software is the same for everybody?
I know very little about the technical stuff but I think it's strange with this huge differences......
Micro SD cards, especially those greater than 32g.
64g and greater SD cards (SDXC) are pre-formatted with exFAT file system, which is not recognized by many devices unless they are VERY current and up to date.
SDXC SD cards need to be reformatted (FAT16, FAT32, NTFS etc..) in order to be compatible with non-SDXC devices.
