I've had my SGS2 for almost 4 months now, running KE7 firmware. Within the next few hours, I'll be getting the SanDisk 64GB microSDXC card, and I'd like to use it in my SGS2.
Based on my reading of other threads in this forum relating to microSDXC support, it's my understanding that the SGS2 hardware will support this card, but that software support will be required to handle the exFAT filesystem, which is the standard format for microSDXC cards.
To determine if exFAT support existed, I did a test last night, formatting a known-good 16GB microSDHC with exFAT and mounting it on my SGS2. However, when the phone powered up and scanned the card for media, it reported that the card couldn't be read and offered me the option of formatting it with FAT32. That suggests to me that the firmware expects micro SD cards to be formatted only as FAT32.
Again, from reading other threads on the forum, mostly related to NTFS support, it sounds like it should be possible to modify the firmware to support exFAT-formatted microSD cards. So I have two questions/requests:
Does a custom firmware package supporting the exFAT filesystem for microSD cards already exist?
If not, would one of the devs like to take a shot at making one?
If this mod hasn't already been made, I'd be more than willing to assist the devs in any way I can. I've been a software developer for almost 25 years, but almost all of my experience is in Windows, and is pretty much evenly split between user & kernel mode, so I know a thing or two about filesystems & drivers.
The last time I did anything in the Unix kernel was back in the days of AT&T SVR4 and SunOS, when Linus was just beginning to develop the Linux kernel. So doing this myself is a bit of a stretch, which is why I'm asking for help from the dev community.
Any help I get would be greatly appreciated.
You would need to grab the kernel source, from samsung or a custom kernel, then build it with fuse support and the correct file system module, or just with extfat support if fuse doesn't have the correct module, the cm7 wiki has a good guide to building kernels then combining them with a ramdisk.
You would need to use a ramdisk from a stock kernel for it to work with stock roms.

Easy for you to say -- my last Unix experience was 20 years ago.
Anyway, I just took delivery on the card. When I stuck it in the SGS2, it offered to reformat it as FAT32, which I did. Once formatted as FAT32, the card appears to work pretty well. SDTools gives read/write speeds of 18 MB/s and 6.6 MB/s respectively; that suggests that the SGS2 is the roadblock, since the card is supposed to handle 30 MB/s reads.
Still, it'd be nice to have exFAT support, so we can use the microSDXC cards as they come from the factory, and to allow for file sizes > 4GB for DVD/BluRay rips and other HD video formats.
Haha, it's easy to say but it's not that easy unless you are experienced in this kinda stuff.
I couldn't easily do it myself or i would
Sent from my GT-I9100 using xda premium
do you wanna say that microSDXC already supported by stock SGSII kernel?
How much free space on this card SGSII shows after format to FAT32?
In stock ROM SGSII supports up to 32GB SDHC, it won't support 64GB SDXC cards, regardless the file system format.
MicroSDXC is working on my SGS2. I've been running the SanDisk 64GB microSDXC in my phone all day. I had to reformat it to FAT32, but it's working fine.
The card shows up as having a capacity of 59.46 GB, and SDTools shows read/write speeds of 18.0 MB/s and 6.6 MB/s respectively. I've played both MP3 and videos off the card, without any problems.
I'll beat on it some more over the weekend, but all signs seem to indicate that microSDXC works as long as you reformat it to use the FAT32 filesystem.
read/write speeds of 18.0 MB/s and 6.6 MB/s respectively

For a class 6 card its normal , read is very good actually close to class 10. My 32GB class 10 Adata Reads 21.3 MB/s Write 15.5 MB/s.
That claim of 30MB/s might be with exFAT or plain BS marketing claims. Anyways i ordered one also 64GB is god send for media storage.
Ordered mine too, will post feedback when I get it (although hopefully loads of other people will have confirmed by then too).
Where did you order?

Hi guys,
Lately ive been trying to get Android running on my HD2…
Ive successfully flashed the HD2 to android friendly ROMs, and installed versions of Android to my SD card… but I cannot get it to run.
I have read some things about needing a certain SD (file system, or a certain type of card/partion size?)… can someone please tell me if my SD card is android compatible… if I can just format it or if I need another card?
The SD card I have is a SanDisk 16GB MicroSDHC. I thought I heard something about needing a “Level/Class 4” or something, but I don’t know what that means.
I hope this question makes enough sense, and someone can break it down for me.
Any help is greatly appreciated.
Cheers.

your sd card is fine. I've ran many android builds off that microSD, which if I'm assuming correctly is the one that comes with the HD2. Do a full format, not quick (so uncheck that box in windows). The preferred allocation size is 32k. If that doesn't work try formatting with SDFormatter
Thanks for your reply mate.
It is the SD card that came with my HD2, but I have the Telstra Version (T9193), so im not sure if it shipped with the same SD card world-wide.
I have just done some more research on the Class/Level Numbers of these SD cards, and I think the Class/Level Number is marked on the card with a circle around it, if that’s the case I have a Class/Level 2 card.
Thanks again for your reply, hopefully once I format the card, I will have more success than I had previously had.
Cheers.
one more thing though... what filesystem should i format the card to?

it says right on the box it comes with a 16gb sd card.. if yours came with something else then the rep or the store owner took the 16gb card out and replaced it.
some shady stores would do this and try to sell you the card it came with.

Corrections, and swift answer
Firstly, flash storage devices marked as class 2 or class 4 would have nothing to do with comptibilty. Flash storage classes are the specifications of the maximum theoretical limit transfer speeds for that type of flash storage device. Take a look at this wiki article to learn more at wiki secure digital class rating article. Next, the type of storage device needs to be specified as microSD rather than SD since they are different flash types. And lastly the proper terms for storage sizes need to be used. GB means Gigabyte which is 1x10^9 bytes or 8x10^9 bits as 8 bits=1 byte, and Gb is Gigabit. The problem doesn't lie in the syntax or intended use of, it lies in the dumbing down, so should someone be wanting to learn these things they are getting taught wrong.
And for the swift answer, no class never makes a difference on compatiblity just whether it has the suffix HC or not, which stands for High Capacity as is reserved for any storage amount of 4GB to 32GB in which case is goes to XC which stands for extreme capactity and is reserved for 64GB to 2TB(TB=terabytes). The only reason this matters is each type of suffix is actually signifying a new type of transfer protocol which requires a firmware upgrade to read the new format(key work firmware not hardware, as one example even the oldest SD card reader could read a 128GB card with a proper firmware upgrade, albiet at lower transfer rates). And the format fat32 is typically used as the standard external storage filesystem.
I hope this answers any and all questions, always remember, what your writing doesn't just apply to you and your not the only one involved. Your words reflect like a butterflies wings.

Id say thats news given that 64GB Micro SDs didnt exist when our HD2 was born.
To be honest, i dunno what id use that much space for, i dont think id ever fill a 32GB SD let alone that monster!
There was a time when id have dual booted android, but i cant be bothered with all that now WP is pretty much perfect on the HD2,
Hi.... Just wondering... Did you experience any change in battery drain and smooth running of the rom after installing 64gig sd card ,
And which rom unr using currently...
This is epic for someone like me! I'm one of those people that fills up 16 gigs in no time flat! 32 sounds nice, but 64 gigs!!!! I'm in heaven, I need to get one. How much did the 64gb card cost you?

THing with Radios is that firstly we have 2 different radios to deal with, and secondly different networks and signal strength areas will do better with different radios, so you may find that the latest and greatest radio is actually worse than the first radio available because its been stripped from a phone on say, the O2 network.
Trial and error appears to be the best, or ask folk on your network what they use, ideally in your own country and even better near you,

According to the SETTINGS|about page, I have 59.25GB Total Storage.
Battery life is not stellar, though I haven't really done any work to optimize that.
SDXC
Basically... All SDXC cards will work...
The thing is, this is how the cards are supposed to be shipped:
SD => FAT
SDHC => FAT32
SDXC => exFAT
Any SDXC card can be formatted as FAT32 to work with SDHC compatible devices. The OS "decides" how much of the storage capacity can actually be allocated.
Since microsoft probably took note of SDXC during development, windows phone uses a file format that either supports exFAT (which is a MS file format) or formats the cards in a file system that supports over 64gigs. Windows phone supports SD cards under 32 gig, so it supports FAT32 and FAT anyways (to be reformatted in the device)
Long story short, as soon as a device supports exFAT it is SDXC compatible. if a device supports FAT32, any SD card formatted in FAT32 works.
Will the 64GB SDXC card work with the original Windows Mobile 6.5 ?
Does exFAT work on WM6.5?
Wohooooo 64 Gb for what?
Yep got a dual booting 64gb SanDisk class 6 over here.

In regards to the SanDisk Ultra 64GB SDXC...over the last couple of days I installed the NexusHD2 v2.3 and set the card up with 8GB EXT4 and 52GB FAT32. It ran slightly slower than NAND but I adjusted the CPU speed to compensate and overall a darn good experience. My next adventure was to dual boot both NexusHD2 and Pdaimatejam's WP7.8 and I split the card pretty much right down the middle taken into account the 200MB FAT32 WP7.8 creates upon it being deleted and for one brief moment you have only 2 partitions before continuing to create the EXT4 partition. WP7.8 will works up to a point and then begins the reboot loop. I understand there's a way to image a smaller memory card onto the 64 gig card and that's what I will be doing next. In the meanwhile I did successfully load Pdaimatejam's ROM into NAND but the key here is that card must be formatted as exFAT; otherwise it too will reboot endlessly. My only use for Android are CoPilot Navigation and Google Navigation and Skype; otherwise I prefer Windows Phone for one reason and one only; it runs as smooth as silk but WP7.8 lacks what WP8.x now haves...good GPS Navs, what my Titans and HD2 have is customization and that is a sticking point for me in regards to upgrading to the Lumia 92x series.

It will fit in nicely becuse it is the same size as the microSDHC.
It doesnt work out of box ;you have to format it in the phone..then you' ll get 59 GB of free space.
No, i dont have it but i have read about it and it works in htc,samsung..
According to specs, memory is upgrade-able only to 32gb.
Will a 64gb card work?
I think you should take the risk and test it yourself
So does it work? That´s a very nice sd card
the defy supports 32gb sd official. 64 gb not supported. I think for any phone 16gb is stable for space and speed. how do they fill up 32gb?!

There are also reports that they are working on many older devices for those wondering. Some include the EVO 4G, original Galaxy S, and even the HTC Desire Z (aka T-Mobile G2). With both old and new, smartphones and tablets being able to take advantage of the 64GB SD cards this is a good sign many more will have the same fate. We can only assume manufacturers didn’t state SDXC support because none were out on the market at time of launch, or maybe there are other reasons yet unknown.
At first insert the device may say corrupt or error, just reformat your 64GB card inside the Android phone or tablet and you’re good to go. While many are currently working, this doesn’t mean they have full support. The chance of the cards failing, getting errors, and possibly losing all your stored data is still a possibility so use at your own risk for now. Hopefully we see more 64GB SDXC cards soon and at lower prices because $219 is a bit steep for me. — Thanks Murray!

SDXC cards use exfat file system. If defy doesnt support that then it probably wont work.
Ive seen reports of it being working on a lot of phones, so there's a chance it might work on defy, but the card needs to be formatted on pc first before using on phone and it wont work at full speed due to limitation on the old sdhc reader (sdxc reader is faster)
I'm asking to avoid risks ).
Why 64gb? Cause i have 32gb card and it have about 4gb left. Actually last few month i've forced to clean up card from time to time. Audiobooks, DVR, Navigation software, record lections on dictaphone... That stuff takes space but i've used not to worry about `if do i have avaliable space left` ). Also this card declares class 6, now i own Sandisk/32gb class 2, so it not just larger, it laso should be faster. Sometimes DVR+Navigation provides some lags, for example.
maybe the max is 32GB,class 10
you can buy but i thin you will see only 32gb space...
can defy uses class 10 sd card? i heard there is problem in taking picture with class 10 card...
read posts on XDA, yes it has a problem with 6 and 10 class

That's strange, is there big difference between supporting 32gb and 64gb? I would have thought that when in development they would have made sure it supported the largest microsd on the market. 64gb (59) would be nice to have.
well, i googled, thanks for making me second-guess myself. here's your answer.
http://forums.androidcentral.com/acer-iconia-a500/141186-64gb-external-microsd-card.html
Yep. Others here have said that it works. It just won't work with FAT due to the limits of the FS. FAT32 or NTFS will work.
Guys,
I have used this SD card for months and it works like a champ. All I had to do was to format the SD in another device since the A500 has no provision for formatting a SD card. I formatted mine in my Galaxy S II, Epic 4G Touch(my first 64G SD Card went in this device anyway). Since then neither device has skipped a beat. The SD cards are expensive though. So be very careful taking them out of your device. ALWAYS unmount it or Eject it within file mgr before removing it. Also handle with care. More questions? Just ask...
Update: That's right! You don't have to unmount or eject it after use in the A500. As a matter of fact there's NO option to do so... But if you use it in another device you may need to unmount or eject it.
Just to add to the information given, a few weeks ago I bought from Woot a "Centon 64Gb Class 10" SDXC card (not micro...full size) for $55 and am using it happily with my A500. I use it with a Targus USB card reader and attach it to the full size USB port on the A500. The only snag which occurred originally was that I used "SD's" own application to format it and it would only format in "Ext", this turned out to be unreadable by the A500 but I resolved the problem by formatting the card in Windows as Fat32. This now works fine and given the size you can put on as many movies as you wish.
Just to add to what ojones838 said above.....Generally speaking the A500 will automatically mount external SD storage or USB storage as soon as it is plugged in (at least this is true of my ICS rom) but it's wise to "Unmount" the storage media before removing it.
Just for future reference, the hardware and software limitations for size are 32GB (FAT and SDHC) and 2TB (SDXC). Nothing in-between those.
Just picked one of these up from eBay. Thanks for pointing these out and the details on how to format and use it on the A500 !
FYI - Just ran SD Card Tester on it and it ran at 5.91MB/s Write and 9.19MB/s Read. So inline with expectations for a class 6 card.
@saeba.....Glad the card works for you, as I said above with that amount of usable space you can put as many movies (including large size blu-ray's) as you want. Certainly enough to keep me happy on my transatlantic flights!
Thanks for the info re the speed test, class 6 seemed to me about right.....have learn't to take maker's claims about speed with a grain of salt.
Hi,
anyone tested this card on XPERIA PLAY?
Is it working?
Rgds,
DocMAX
Pretty sure the Xperia play can only support up to 32GB since it's 2011.
i have heard other things
Before moving to a nexus 5 I used a 64gb card with zero issues for almost 2 years. You have to format it in your PC as fat32. Works great after that.
I don't see how a 128gb card wouldn't work. Also if you google searched XDA xperia play 128 about two years ago someone hacked a 128 SD card to work and it did.
ok. can anyone confirm a 128gb card?

I believe you can support the card if you partition it to smaller 64 or 32gb partitions
Use ntfs moubter from android market. It will mount anything no matter the size even 1tb. Also your sd will not wear out. Ive found they wear premature if over 32gb and formatted to fat32. Ntfs mounter will mount sd cards as per usual so just slap it in allow root and away you go.

Yes, they work fine so long as you wipe the default exFAT partition cards of these size ship with from the factory and make a FAT32 partition.
Linux users can do this with no problem using something like (G)Parted or fdisk, while Windows users will need a third party program to overcome the artificial 32GB FAT32 limit imposed by Windows. Minitool Partition Wizard Home is good for this purpose, and free.
