I have the same issue as well and if you format to exFat in Windows and then insert it into the V20, it says corrupt and needs to be formatted but will only format as mobile storage and FAT32. We need a fix for this.
i fixed it by flashing the konverged kernel
I guess this is still a problem. I have flashed mk2000 to fix this issue however It seems the phone runs much better with the stock kernel. I'm running A-O Oreo.

I have the strangest feeling this has already been answered somewhere...but i've scoured the internet and havent found much of anything on the topic. I've read some mixed statements saying ppls sgs4 see's an external sd card formatted as exFAT, others say it isnt working for them. I've figured out a way to get the hardfloat Kali Linux ARM gui terminal working and all applications installed running in a chrooted environment...however the image size needs to be a minimum of 6gb to install all programs. I'd like to go with 8gb just to give it a little play. I have an SGH-I337 (AT&T) and am rooted, i've tried stock rom w/ stock kernel, stock rom w/ KTweaker kernel, said it supports exFAT but did not work. Also i've tried Cyanogenmod 10.1, but havent tried the KTweaker kernel w/ cyanogenmod yet. After formatting the 16gb microsd i have to exFAT and inserting it into the phone it states "Preparing SD Card"...and immediately says "SD Card is safe to remove". Anybody have any insight as to how i can get around this 4gb filesize limitation? Any input will be greatly appreciated. Thank you.
Here's the deal.
All cards 32gb or less (SDHC cards) come formatted in Fat32.(Part of SDHC spec) This includes a file limit of 4gb max for a single file.
All cards 64gb or more (SDXC cards which the S4 supports) come preformatted in exFat (Part of SDXC spec). This does not have a 4gb file limitation.
The stock Samsung / AT&T Firmware supports exFat. (I bought a 64gb SDXD formatted with exFat and plugged it in and worked right away). Most recoveries do to. (TWRP does at least).
However, I flashed CM10.1 onto my S4. CM10.1 does _NOT_ support exFat. Initially I backed up and reformatted my card in Fat32. Angry with the 4gb file limitation (I have many 720p and 1080p movies over 4gb..) I actually took the microSD card out, used a adapter and hooked it up to a Linux system (Ubuntu 13.04 in my case) and used gParted to format the card to EXT4 filesystem. EXT4 is a filesystem most Linux machines use and support natively. This is actually the filesystem most newer Android device use for their internal SDCard / Data partitions! I popped the card back in, CM10.1 reads it perfectly! And I was able to copy files over 4gb to the device!
So its not a hardware thing since the S4 is SDXC compatible. Just formatting / partition time issue.
I greatly appreciate the breakdown! However i do have a question, since the sgs4 supports exFAT, why does it not see it after i reformat my 16gb to exFAT? Is it because it is an SDHC and not an SDXC? Also, does the type of recovery you have installed alter what filesystem types are recognized?

No problem!
As far as the spec goes, if it's formated in exFatand its SDHC it should still read it fine. Filesystem is just a filesystem. The spec just says what is used by default on cards.
One possible issue though, did you format your card in your phone? Sometimes the odd way these work the SD cards like to be formatted in the phones themselves. It worked formatting from a Computer for my ext4 case, however that does not work for all cards/phones/filesystems sometimes.

I've tried formatting from phone, 3 different computers (one computer running Debian), cfdisk command line as well as gparted, also window's format utility. It seems though nothing is working however after going to Cyanogenmod 10.1 last night and formatting the external to ext4 the phone only displayed "Reading SD Card" then "SD Card is blank". It works perfectly fine whenever the phone formats it, it just doesnt like any other type of filesystem. It is a polariod sd card which gave me issues in the past. Hopefully i can get this resolved and post more on it. Probably just something small i'm missing :/
Anyways, thanks a million on the input!

As far as I know there aren't and posts saying it supports it but I've used TWRP with exFAT, Ext4, and FAT32 formatted ROMS.
roms not reading 64gb sandisk sdcard
I have the 64gb sandisk ultra class 10 sdcard... and it flat out works in stock... even when I recover. But doesnt work atall using wicked rom and a couple others. ExFat is the reason... those roms dont support it...
You can use this kernel to get exFAT support on custom ROMs such as Cyanogenmod:

Just got a SanDisk microSDXC 64GB card from Amazon for my Galaxy S4. I don't want to mess anything up, so I've got a few questions.
Are these cards formatted with exFat? How can I tell? Do I need a special kernel to have it work? Will the stock kernel work?
Should I format it from within the phone before use?
Any other problems/concerns I should have before I copy all my music and ROMS over to the card?
Thanks in advance,
Foulwx...in Atlanta tonight where there really is some foul weather.
I recently purchased a 32GB SanDisk Ultra, and followed the instructions at these two links, for moving apps to the sd card:
http://forum.xda-developers.com/showthread.php?t=2142844 - mini partition tool guide
http://forum.xda-developers.com/showthread.php?t=2285221 - link2sd and foldermount
If you have some way to connect the card to your PC, the mini partition tool guide is really easy to follow. If you don't plan on moving apps to the card, you could just toss it in the phone and format it there. I screwed up the partitions a couple of times on my own (formatted the card 5 or 6 separate times, trying out different filesystems and partition sizes), before I found the mini partition tool guide, so I don't think there's much chance of permanently ruining the card.
If you formatted the card into fat32, then it would be more compatible without modifying anything on the phone.

You can connect the microSD to your PC to determine what format it currently is. If you stick in the phone, it'll format to exFat. The exFat format can be recognized by the stock kernel as well as the agat kernel and the ktoonsez kernel.
I have the same one. Just put it in my phone and went from there. Guess it auto formats it to exfat that way.
I flashed bluKuban and had to switch to agats kernel to see it. But otherwise works well.

Is there an advantage to exFat over FAT32?

exFat can have files over 4gb.
I killed my sandisk 32gb ultra card ...created the fat 32 partition and then the exfat and it won't be ready by the phone at all. When I put it into the computer it shows it only has 30.6 MB...I'm unable to format it through windows or with another app. Any help would be appreciated

Insert it into your phone, and format it there. That "may" fix it for you.

Its not being read by the phone it doesn't even mount..
I'd try plugging it into the computer and running a partitioning program. It should see the card no matter what. Partition it to whatever format you want.

Theres one computer where it sees it and I connect it through an HP printer that had an SD slot.. Windows shows it as 30.6MB and asks me to format it but the format fails. I tried SD card formatter, HP USB disk tool..I don't know what to do
OK, I loaded all my music, pictures, and roms onto my 64SDCard from my laptop. Windows says it is exFat. Booted and seems to work fine.
Then I went into OUDhs recovery to try and make a nandroid. It can't mount the external_sd. Suggestions? Do I need a different recovery or kernel? I'm on the stock kernel.
Thanks again.
Edit: I installed TWRP 2.5.0.3 and it worked fine, I think. I haven't tried a restore yet.
I finally gave up with exFat and, after some research here on XDA, used Mini Tool Partition Wizard Home Edition to format my SDCard to fat32. I just made a Nandroid with OUDhs recovery. Hopefully, everything will continue to work OK and I don't need any 4GB files on my card.
Dear Friends,
I have a 64 gig, Class 10 sd card that I have formatted to Fat32 with GuiFormat, and am trying* to use with my S4. The problem is the seemingly notorious issue with extreme data corruption! Every photo I take becomes corrupted Fast and I get the dreaded Black picture with lighting bolt logo in the Gallery. Titanium and Nandroid backups get corrupted almost instantly as well. After Googling a bit, it seems it's a WELL known issue with these S4s. Here's an example of exactly what this issue is:
http://forums.androidcentral.com/samsung-galaxy-s4/315699-micro-sd-card-corruption-issues.html
I decided to post on XDA because there's generally NOTHING unsolved here and was wondering if someone can help me solve this issue? I will be DEEPLY grateful!
Last Note: Before you recommend Samung and/or SanDisk cards, read the thread I posted, seems like people still have problems with those as well! I need a near guaranteed solution to fix this problem, before I buy the expensive sd cards...
Appreciate all your help in advance! Thanks!
Couple things.
Try and reformat again on PC using gui format - fat32.
Then run a chkdsk on the card while it's in the pc.
See if that works.
OR
put the card in the phone and use Philz (or whatever recovery you're using) to format the externalSD card exFat.

Thank you friend!
I have tried 1, that's what's still causing the corruption.
2, I will try... but isn't exFAT NOT recommended to be used to avoid sd problems?
Thank you!
I use fat32.
But some report they use extFat, can always try both.

Thanks, are you using a 64 gig card and have seen NONE of these issues I mentioned?
Got two 64GB cards - these.
I decided it would be best to take my new cards and format them fat32. Used guiformat.exe.
Had my neice and nephew also use this tool to format their cards for their S3s.
Also have a buddy whose got a 64GB and able to use it in his GS3 after formating it fat32 using guiformat.
Really sounds like you got a lemon of a card. You might want to see if the manufacturer will RMA it.
Maybe you got one of those knock off microsd card that says it is 64gb but is really only 4gb. It starts rewriting over itself after 4g of data.
Hi,
I have put a micro SD card into my Xperia Z2 but the phone is saying that the card is damaged. There were some films on it previously but now I can't format it.
please help.
On another note, what is the biggest size microSD card that the Z2 is able to support?
128GB maximum
Sadly the stock firmware only supports fat32 filesystem
Is your sdcard formatting in a different filesystem, Exfat?, NTFS?
Is your PC be able to read your MicroSD?

Are you sure stock doesn't support exfat? i'm currently using existenz 4.0 on a LB with a 64gb exfat microsd card no problems it works fine in twrp recovery too. As far i can remember it was working on stock rom too but i'm not sure...

Now that i think about it, i think exfat and fat32 are supported
Twrp doesnt count by stock firmware, twtp should support all formats from ext2 to fat16
ExFat is supported by Sony stock. I use 128Gb microSd but the only problem is delay in storing pics and videos.
If your card is getting damaged its because of partitions getting damage.
Use SD-card formatter and format with it via windows then use.
I was messing around today and installed the RR Oreo rom. Rom was great but I was cursed with the call bug. Caller couldn't hear me and I couldn't hear them. I went back to stock B32 and am now getting the message my SD card is corrupt. It isn't. TWRP can read my sd card fine and if I flash the Oreo Rom again it recognizes it without issue.
Any ideas on how to get my SD card back working with stock? Its 256G with a second sim attached. It's very difficult to backup all my goodies.
SOLVED: Thanks to @Srgqw Magisk 15 caused the corrupt card issue. Magisk 14 works with exFAT.
If you want to stick with this rom there is no other way other than backing up all your goodies and formatting it on this particular rom.
Get in twrp and connect to your PC, back everything up, boot your phone, it will ask you to format to use the SD card, follow those instructions.
Many had the same issue on PNW ,(first Oreo rom for this device) including myself.
Sorry, I missed that you went back to your old rom, I don't know about that. I formatted mine on the new rom that caused the sd card issue. But it's always good to back up and try since you can never trust SD cards lol
@JKSurf: I recommend AOSP Extended Oreo. It reads FAT32/exFAT MicroSDs perfectly fine for me.
Formatted micro SD to FAT in TWRP. Now B35 will read it. Pesky 4GB limit though ?
