For example: if an old phone only supports expandable microSD up to 2GB -> A 64GB microSD card won't be compatible with the old phone/camera since mostly memory card over 32GB uses exfat file system, for example the SDXC has exfat file system set by manufacturers.

Solution -> use a 2GB memory card or less for the old phone/camera, and format the memory card to be fat32.
