The Patriot microSD 32 GB is the right size, but often still does not work because the Canal Toys Photo Creator Instant only supports very simple microSDHC cards (up to 32 GB, FAT32) and cannot cope with certain card types/controllers or formats (e.g. exFAT/UHS). Solution: classic microSDHC (8-32 GB), explicitly FAT32 formatted, preferably without "high-speed" extras.
