Something I've been meaning to ask, simply because it's a wierd occurrence. A few days ago, I got a new 64gb Samsung micro SD card. Naturally, I had to format it into FAT32. I went to format the card using my S III (because it has helped put both my 32gb cards into FAT32). Format successful, and I moved a bunch of backup files from my other card onto it, and hooked it up to my Galaxy Nexus using my Meenova reader. The storage mounted, but it couldn't be accessed. The format of the SD card, I found out, was exFAT, not FAT32. My question is this: why when you use the device to format it does the 64gb card get put to exFAT instead of FAT32? I had to use my laptop to format it I to FAT32, just like the last time I got a 64gb card.

I've always had to use my pc, I think the phone is only set up to format it in exfat because you can transfer larger files than fat32. I may be wrong though.
