Samsung's specs for my Galaxy S3 say:
128GB MicroSD cards probably didn't exist when this phone was made.
If I insert a
128GB MicroSD card, will the card:
- "not function at all"
or will it:
- "work fine" but only let me use 64GB?
It will work fine and you'll have access to the entire storage space.
It's usually just a recommendation for a better user experience in my opinion, If I used the recommended maximum SD Card size on my device It'd be able to load all my photos, music, app data without any serious delay, however if I put a huge SD Card in my device it could take hours to load 128gb worth of photos, Therefore it's necessary to recommended a maximum size for the best user experience.
You will need to format your SD Card to Fat32 on a PC if it's not already formatted.
A good free software for this on Windows would be
I had an 32GB SDCard that had 16GB in ext2, and 16GB in fat32 (in think it was fat32, but I don't recall exactly).
I had no trouble using it under a Samsung Galaxy Core Plus, though I only had access to the latter 16GB, so in the worst case scenario, you'll probably get away with creating an unused 64GB ext2 partition on your SD card
