If the phone specifies that it's compatible with SDHC and not SDXC, then the 64 GB card probably won't work (or could be really buggy). The max storage for SDHC is 32 GB.
I've found that the maximum SD card listed in official specs doesn't necessarily mean that a larger card won't work -- but they can't guarantee that it'll work correctly, so you're taking a risk if you use the card for important data.
