Yes, yes, but it's still quite odd; you don't often hear about manufacturers/carriers underestimating their own devices.

In other words, has anyone actually tried filling a 64GB card to max capacity with data on the phone itself? Or is it only addressing the first 32GB like I would expect? Just because the card happens to be readable doesn't mean it's actually fully working like it should, so I'd still be wary about landing the money on a 64GB card for a phone that Sprint claims supports up to only 32GB.

If it *is* only addressing the first 32GB, then the only remotely possible option to get the full 64GB capacity is to re-partition the external SD as two 32GB (roughly; probably a little less) partitions. However, that's a *very* big "if" as to whether or not that actually works, since SD cards (and other flash-based external memory devices like USB thumbdrives) are designed (and expected) to have only one large partition. Similarly, you'd have to do some serious modding to get both partitions mounted (if the phone's card reader itself isn't the limitation).

In all likelihood, even that above solution would probably not work due to hardware/firmware limitations. This is similar to giving older computers big hard drives; even though the hard drive will certainly be usable, many older BIOSes are incapable of accessing anything beyond a certain capacity (in the case of an old Compaq laptop I have, that limit would be 10GB).

tl;dr: don't assume that the ability to mount the SD card automatically means all the space on it is accessible from the phone.

i ordered this card after seeing this thread.
it came in today.
i cant get the phone to read it.
i formatted it and tried everything.
dunno whats up.

It's never ALL accessible whether it's supported or not whether it's computer phone or any device. Making two partitions would have you lose even more space and isn't necessary, once card is formatted to FAT32 it WILL work people.

I have been thinking alot about getting a new card.But after I looked more into it 32gb is a max. I could really not use up 64 gb unless I am loading it up with my girl's Disney movies and Transformers G1 episodes.
With 16gb internal and 32gb ext. that would be more than adequate,cause most of the time i am transferring data back to my PC. Especially backups and ROMS.

Trust me this is one of those things that once you get it your going to be asking yourself why you didn't always have it this way and that you need it

64 gb works perfectly in my phone, all you have to do is format it once through and bam double the max of what the box says, the extra space is well worth it

What class SD is it? I am curious if it truely makes a difference between class 6 and class 10. Never saw any comparisons on them.

I think you misunderstood what I'm saying. Splitting into two partitions will create some overhead with additional file allocation tables and partition data, sure, but it's nothing compared to losing half of your card's capacity because the device you're using the card on isn't capable of addressing past the 32GB mark. There's a difference between "it'll work" and "it'll work correctly", and in this case that difference is 32GB of potentially-inaccessible capacity.

So, I reiterate: has anyone verified that the phone is capable of reading and writing to the entire capacity of the card? Does it recognize the card's capacity to be 64GB (or something close)? Does writing more than 32GB worth of files actually work, or does the operation fail (or worse, overwrite data)? I'll see if I can get my hands on one of these cards so I can perform this kind of test, but until someone confirms this, it would be wise to maintain some healthy skepticism, lest you buy a fancy 64GB card just to figure out that it works no better than a 32GB card.

It has been verified by a few users in this thread already as well as others. Read a bit of this http://forum.xda-developers.com/show....php?t=1799634(as long as it is an actual SanDisk card then there is no reason to worry) it will work.
