As I said, micro SD, micro SDHC and micro SDXC are STANDARDS. Therefore all micro SD[xx] cards of the same standard are effectively interchangeable (between phones and adaptors). BUT companies don't always interpret standards identically, so occasional issues do crop up, so there's no 100% compatibility guarantee - only about 99%.
