Hi everyone, just wanted to confirm that 64GB MicroSDXC cards do work. I bought this one http://www.amazon.com/dp/B007WTAJTO/ref=pe_175190_21431760_M3T1_ST1_dp_1
At first it will not work, but you must format it with the phone and it will work well. Reports 59.6 GB

having tons of problems with mine; tried formatting in Windows (FAT32 with "guiformat.exe"), formatting in the device a few times...
Every time, when trying to copy stuff onto the card from my Windows machine, after a few GB the connection just drops...and then the card doesnt seem to work properly until re-format. Everything is *extremely* slow to respond, even to the point of screwing with explorer when I open "Computer" in Windows from the start menu...
Bad device? Bad card? PEBCAK?

Probably its a fake, do a google search about fake flash drives and memory cards and use the sugested program to test the card.
Warning, it will be slow.

believable- this is why I only buy Extreme Pro CF cards for my camera
alas...the Extreme Pro line stops at 16GB for the MicroSDXC line, (perhaps thats a hint at the difficulty of reliably making rad MicroSD cards?) and I'll be damned if I have an Android with less storage capacity than an iPhone.

Doubtful...sold by Amazon.com LLC. I don't buy eBay shiest unless I can't find it on amazon or somewhere that either accepts google wallet or is within driving/shouting distance. Still though, I took your advice and downloaded H2testw and will run the test tonight.
Thanks for all the ideas guys!
That used to happen to me, got very frustrated because I could never copy things to my flash cards. Turns out the problem was my card reader. Try getting one of the USB ones that can actually read SDXC. I don't have one, so what I did is put it in the phone, then connect via USB to the computer in mass storage mode and it worked great.
I had the 64GB SDXC as well, it at first seemed to work, but don't be surprised if it stops working. Motorola, and I believe stock Android do not support SDXC yet. I have a somewhat detailed thread here: http://www.droidforums.net/forum/dr...d-cards-hd-maxx-hd-class-10-32gb-vs-64gb.html
When I got my card, popped it in, it formatted correctly, and seemed to work fine. As I started to put it through its paces it started to just not work. On ICS when you used the Storage option to transfer media to the SD card, it would stop halfway through and throw out errors. Eventually certain apps would stop writing/seeing the card like backup apps etc..
Be careful going forward, and test it hardcore. Transfer files back and forth, I always had issues with movie files. See if Root Explorer or other explorer apps can see it, see if Titanium Backup or My Backup Pro/SMS Backup can see and write to the card.
And yes, I did not get a dud, its works in other non-Android devices and works and tests perfectly in multiple computers. Just be cautious.

These are all the same symptoms I'm having. Well, it looks like Motorola actually had testing and reasoning behind "supports up to 32GB" :-| That'll teach us to think we're smarter than the factory QA guys...
Still though, it's a little disappointing.

Indeed, some of the Sammy devices support the SDXC 64GB card, but I think that's baked into TouchWiz. Hopefully as SDXC gets more popular it will become supported by Android all together. It would be nice to have at least half of my music library on my car so I don't have to stream all the time lol.
Confirmed working with a 64GB SDXC, works pretty well actually, now I'll never run out of space.
I bought 2 64GB micro SDXC cards. One for my Xoom and the other for my upcoming XT925. My Xoom was unable to format it so I used EaseUS Partition Master to format my 64GB cards as FAT32 partitions. So far so good...
I tried my sandisk SDXC 64Gb yesterday with no luck. It was formated to exFat though. I will try EaseUS tonight and try formatting it to Fat32.
Cheers

I just got a 64gb micro sdcard, when I first put it in my phone it was exfat formatted, so my phone couldn't read it. Once I formatted the card with the fat32formatter (found online), it worked great. Good luck.

I have a 64GB card. No issues.Took the card out of my Maxx.
I bought a 64 sandisk sdxc class 10 and tried it in the phone. Didn't work. Formatted to fat32 with a partition program, still wouldn't work. Got fed up, deleted all the partitions, threw it in the phone and itr was recognized, but blank. Had the phone format it, and it works. Phenomenally actually. Haven't tested read/write, but I've filled it a few times over looking for problems and had none. Without looking I think I have just shy of 40 used on it right now.
You'd think Motorola would say something about that.
Got a 64gb sandisk class 10 and it's really buggy.
Forceclose/card disabled automaticly/cant see my files/Many lags.
So for me the xt925 is not compatible with it.
I've been using mine for about a year now, it's been working flawlessly. I had to format in my phone the initial time I first used it.

Ok, after buying a cheap and corrupted 64gb micro sd card, I went and spent the money on a 64gb sandisk card. It works just fine. Now, I am rooted and have synergy rom build 104 which is also running fine. I noticed before I flashed the rom that cwm wouldn't recognize my external sd card. I read up on that and found that cwm won't read cards formatted to exfat. So, I formatted the card to fat32 and remounted, transferred all my music back onto the card. Everything worked just fine until I plugged my phone into my computer. I was able to open and navigate through the files like normal, except when I went to open the music folder where all my mp3s were. I tried this on 2 different computers and on both the computer froze with the sand timer. The phone itself was fine, my music player(poweramp) was and is able to play the files with no issue. Also, when I unmounted the card and put it into a card reader and then connected the card reader to my computer and voila! Everything was fine, I was able to open the music folder and scan through the music files. I am not sure what the issue is. Can anyone shed some light as to whether this is a phone/rom issue, a micro sd card issue, an mp3 issue? Any ideas would be appreciated.
That sounds like a bad sd card. Have you ran a checkdisk on it?

If it's a SanDisk 64GB MicroSDXC UHS-1 then they have a replacement program where the older cards had issues in the S3/S4 devices. They sent me a free replacement and everything seems to be working. No Damaged card errors as of yet.

Hm, been searching around for this exact issue. Coworkers S4 with this exact SD card has been getting the removed unexpectedly error. Reformatted a few times, restarted phone, error comes back. It's in my Note 2 at the moment for troubleshooting, and so far so good, but this makes me move more toward an actual SD card issue in combination with the s4, and not the phone itself.

The SanDisk issue only affects the Galaxy S3/S4 as they told me. My other 64gb Sandisk card works just fine in my tablet.

I called them and they are going to exchange it out for me. The weird thing is that I didn't get any damaged card error messages on the phone itself. It mounted it as soon as I popped it in. Even after formatting to fat32, it mounted right away with no issues. It only happened a couple days after I transferred all my music onto it. Is the free replacement they give you a newer card or newer model number?
+1 to the above. SanDisk told me they have a new version of the 64gig card with updated firmware, specifically for the S4. Package tracking shows mine is to be delivered on Monday.

So are all 64GB cards having issues, like other brands? I want a 64 bc my backups are freaking huge and taking up space. And with being rooted how would I transfer everything to the new card without messing up the phone?

So when this card tanks, I have to drop the big money on a card specifically made for this phone. Is this a problem with existing cards or did Samsung do something that required this firmware change?

They told me that too. My guess is it's due to the mass recall of the chips for the S3/S4. They said it's not present in Tablets so my 64GB in my tablet would be fine.
+1 problem with Sandisk 64Gb UH-1 card. Unexpected removal error. I am writing just for statistics. Just got my new Verizon S4 - and have problems...
FYI - I'm having a similar issue with a Samsung 64GD card. Got it to see the music for a while yesterday but after a reboot it can no longer see it.
Update, I received my new card and just popped it in. My phone automatically formatted it to exFAT. I'm not going to try changing it to FAT32, but is there any version or way I can get cwm to recognize the card in exFAT format? I tried TWRP, but when I flashed a rom it soft bricked the phone so I would like to stick with cwm.
I have the 16 gb s4 and its great an all that we have a micro sd slot but I have found the whole concept unreliable at best. For one I have had 2 different sd cards fail. One gskill 32gb class 10 and a samsung 64 gb fail. All my pictures, roms and app gone. I back them up but still not being able to trust them is a huge concern. And the 64 gb seemed like a great idea except you have to format it fat32 to get recovery to view it, and when I did that my phone constantly wanted to format it back exfat. I pretty much have no option to get a 32 gig with a mdk rom either. Just my rant as I figure out how to rma both of these cards.

Sounds like you've just had some bad luck. I've been using a 64gb Class 10 SanDisk formatted for exFat and it's worked fine so far (I even use Folder Mount to move a bunch of stuff from internal to external).
Surprised the Samsung card failed on you.
Btw, the exfat/64gb issue only exits for some implementations. I'm running Barebones ME7 rom w/ktoonsez kernel and Phils/CWM recovery and both the recovery and the kernel support 64gb exFat.

I've never had any SD card fail me. Never heard of gskill and there is the possibility that the samsung sd card you got was a fake...depending on where you got it. I've used PNY, Samsung, and SanDisk sd cards and all have lasted me a long time through heavy usage.
I have a 64 gig sd card and never had an issue. I use it all the time.
first thing I did was wipe and format it in twrp recovery to whatever format it wanted.

Two cards failing? Unbelievable bad luck (I have never had a storage device of any type fail...not even platter hard drives...and I'm 43 and have had my own pc of some sort for 25 years), a bad card reader in the phone, or operator error.

I feel you on that though, sucks to loose all the pictures. Wouldnt get recognized on either of my pcs, Old 8mp digital cam tried to format it but couldnt do it.
I bought an authentic sandisk 32gb microsd to replace it, so far so good.

You need to go buy a lottery ticket, hdd/ssd/ram are the number one thin besides power supplies that die in computers. I have had probably a 10 percent failure amomg desktop ssd's since they first got popular. I build alot of computers and its definitely a brand/product line importance.

I had an almost identical issue a while back. I used to always use a Sandisk 32gb class 10 card in my S3 and other devices. I used the same card for 3 or 4 years. When I got my S4 I decided to make the jump to a 64 gb card due to the small internal storage. So I went out and bought a 64 gb Class 10 Sandisk since I have always had good experiences with their cards. First thing I popped it into my computer and re-formatted it to Fat32. Then I plugged it into my phone and it seemed to work fine for a while, then randomly it would unmount itself and remount for no apparent reason. It would do it randomly 3 or 4 times a day. I tried wiping and reformatting to fat32 again, tried exfat, and even NTFS. Failing all that I took it back and exchanged it for another identical one. Same EXACT issue... So I gave it one last shot and exchanged one more time. At this point the ladies at Wal-mart are looking at me sideways like I'm running a scam or something. Lol. Anyways, the third one worked spectatularly. I haven't had one single unmount with it and I have all the storage I could possible need. I keep two Nandroid backups on my memory at all times (and with the S4 they are HUGE, 4gbs or better) and I have like 15 gbs of music, not to mention other miscellaneous files and apks and such, and I still have 30 gbs left.
I say just try it again man. Third times a charm. And I personally would always recommend Sandisk. I have never had one fail me and lost my data or anything. They have always worked for me.

Did you format back to Fat32 on your third try? I am going through the same thing and I am on my second card, waiting for the third to come in the mail. The first one I did Fat32 and out of the blue it would get extremely hot, and then say safe to remove card without me doing anything.
The second one, I left as is, copied everything over and left it exFat. That lasted about a week and then stuff started disappearing in gallery view, BUT it was there in Root explorer. The card it a Sandisk 64 gb Mobile Ultra.

Yeah mine was the same issue, only I didn't notice any heat to speak of. And yes on the first card I got, I used a windows program called fat32format and formatted it before ever even putting it in my phone. It would intermittently unmount and remount exactly as you are describing. So I took it out, wiped and reformatted to fat32 again. Still did the same thing. So as a last ditch I tried formatting to exfat. My phone and recovery both read the card just fine, it would just unmount randomly, or when I was either listening to music or viewing my gallery (something that required high read speeds) and it would unmount and interrupt it. So, thinkiing that it was just a faulty card I exchanged for a identical new one. Same issue. This time I used a different program to reformat to fat32, I forget the name of it, but it was a command line based reformatting tool for windows. I used it and had that same problem even after several reformats. At this point I was starting to wonder if it was a problem with my phone's SD card slot., So as a last effort I did one more exhange, reformatted using the command line tool and haven't had one single unmount since then, and I have ALOT of stuff on it. I would just suggest keep trying. I think that Galaxy phones are just sensitive to card reading and if you don't have an absolutely perfect one it will have problems. Or who knows, maybe I just had that off chance of one in a million by getting two bad cards in a row. Either way, I would suggest reading this thread (if you haven't already): http://forum.xda-developers.com/showthread.php?t=1773735
Use the first method on your new card. That I think is the most foolproof formatting method. Good luck, you will find the right card eventually.
Thank you!! Ill give it a shot tomorrow when the new card arrives. I appreciate that thread reference too! Fingers are crossed.

Yeah no problem. Good luck
There may be a pattern....
But I am not sure exactly what it is.
I have two nearly identical SG4s (1 for + 1 for my wife) and both have the 64GB SanDisk Micro Ultra. One phone is completely stock (my wife's) and the card is lightly used and formatted exFat. Mine is rooted and Roomed (Synergy) with TiBkup and CWM. Like other folks, I had to reformat the card to Fat32 in order to work with CWM.
As far as I can tell, she never sees any un-mount/re-mount messages on her phone but it is lightly used and she might not notice. I DO see occasional un-mount/re-mount messages, but I cannot tie it to a specific program or event. Sometimes happens right after reboot. Sometimes happens when I launch TiBkup. But goes for days with no issues.
I have never lost any data or noticed any performance hits, but now I am worried that I might.
Guess it is time to take more backups of the backups...
I have had lots of computer equipment fail over the years, but never exactly like this...
Well I followed everything nicholi2789 suggested and low and behold my card is actually working good. It does not get hot when reading ( not as hot as the other 2 anyway) and I can see a big time difference in speed. So I guess its true, the third times a charm in the case of these 64 gb Sandisk Ultra cards.
Big thanks again to nicholi2789 for pointing me in the right direction!
I bought a SanDisk Microsdxc class 10 64gb and let the phone format. It's working great. It has the fastest speeds out of all I've seen.

Glad you figured it out man. I didn't really do anything except to say keep trying. Lol. Good deal though.
The phone will claim its checking the card & then claim the card has been removed.
Anyone else with a 64GB card have this issue? My Lower gig cards work fine.
My SanDisk 64 GB card works fine here. Hard reboot your phone.
Having same issue factory reset did nothing either. Even after this little ota
Backup card to PC. Format it, and see if that helps. If not, you may need a replacement.
My 64GB SanDisk is working fine. Just ordered a Samsung EVO 128GB, should be here tomorrow (oops, no later today) I think.
Like others said. Reformat it. I'd let the phone format it.
It happens sometimes. These cards easily get corrupted too because they often run a weak file system format like FAT or ExFAT. Sharing between PC and Phone is shaky too.
I like HTC phones because they support true USB Drive mounting which is less prone to issues IMHO and much faster too. MTP is awful.
Yea my sdcard is fubard, have to testdrive rebuild, it has lost all writing priveledges. This is all caused by my old piece of **** galaxy s4. ****ing thanks applesung

Well just picked up my new A52 5G really enjoyed it at first but now my SD card keeps getting unmounted every time I restart the phone. ( The best part about this is the SD cards are made by Samsung tried 2 different ones both are 128G) (SAMSUNG: EVO Select 128GB MicroSDXC UHS-I U3 100MB/s Full HD & 4K UHD Memory Card with Adapter (MB-ME128HA)
The typical SD problems Samsung is known for. Asking Samsung for solutions is not very informative. Please any suggestions would be great.
If not I guess I just ditch Samsung A52 5G and go back to the other evil the iPhone. Heck at least every time you turn that on it always works.
This sure seems like a great phone but that SD card issue is really a big deal at least for me.
HAve you tried the same SD cards on other phones or a different SD card on the same phone?
Yes, I actually bought 2 exact same cards, no issues anywhere I use them except in the new Samsung A52 5G.
Reading a lot of other posts seems to be a pretty big issue with Samsung and Android 11.
( https://eu.community.samsung.com/t5...afely-to-prevent-your-phone-from/td-p/2967455)
What about if you borrow a card from a different brand? I swtiched the old SD card i was using onto my A52 5G and never had any issues. Could it be a problem with samsung cards? For reference I use a Kingston 32GB MicroSDHC with UHS 1
Try formatting card in phone if that doesn't get it try doing a low level format on the PC with a 3rd party app do not use the Windows formatting utility.
Then format again in phone.
Load card through phone.
Formatting the SD card was the first thing I did using a Linux PC. (Manjaro OS ) This was always my goto if I have formatting problems. The SD card was done in exFAT, however no luck.
The other option is buy a different brand SD card as mentioned above by "ImGonnaTryScience". (Thanks)
The card I'm looking at is the
SanDisk 128GB Extreme MicroSDXC U3, V30, 4K, A2, Micro SD.
I'm thinking maybe the Samsung SD cards are to slow, but who knows.
What doesn't make sense is the Samsung SD cards work everywhere with no issues.
I even have an old Galaxy Tab 7, Samsung SD cards works great in that. Speaking of my old Tab 7 I tried formatting the SD cards with that and then put them back into the A52 5G. This didn't work either. My thinking was Samsung should like Samsung but my thinking was wrong. (Maybe I should stop thinking.)
Speed in SD cards matter sometimes (for example the SD card I use in my dashcam needs to be a certain minimum speed otherwise it won't be able to record properly), but I find it very odd that it wouldn't work for a phone.

Not giving up just yet, I really like the A52 5G.
V30 should be fairly fast from internal memory to SD card less using the C port.
If you did a low level format then put it in the phone with not data on it, then formatted in the phone again... it should work.
I've had issues like this on my S4, now you see it, now you don't. I had to do a low level format to make it readable even on Windows. May have been a bad card but all sectors were intact.
May be card brand. Even afterward it would not see the requiring a reboot.
I'm using the Lexar .5tb V30 card in my Note 10+ and unlike what happened on the S4 the 10+ recognized immediately. Formatted it in the phone and zero issues since.
OP I feel you. This is a frustrating issue that really jams a monkey wrench in the cogs.
I be seeing red.
Pedal to metal, no brains diagnostic solution; get the Lexar card if the size and speed rating fit your needs.
$64 and known to work out of the box.

It's not a ram stick but better safe than sorry.
Well I may have solved my problem. I completely wiped the SD Card using MiniTool Partition Wizard. However I didn't add a partition or any kind of formatting. Once the card and partition was completely wiped I put it back into the A52 5G and let it do its own partitioning and formatting of the SD Card. Everything is working really well no more SD card errors, just hope it holds. ( 12hrs and still working, before that the error would pop every 30 minutes or so.) ( Still using my original SAMSUNG: EVO Select 128GB SD Card)
I'll update the progress in a few days.
Some reason the wipe of the partition seemed to do the trick. I don't really understand why since like I said the card worked well in everything except the A52. Maybe Samsung changed the format structure compared to there previous tablets and phones. Maybe its even an issue with Android 11 . All formatting in the past was always exFAT however something changed with this phone. I hope this will help out others who may be experiencing the same problem.

It's possible there was some app on it with a secure partition or something.
It may take or do what one card* did in my S4+, while never lost data it would go through spells of not being recognized by the phone requiring a reboot. No rhythm or reason to it.
Having to low level format a new card is not a good sign.
Next card get a Lexar, slam it in, format, good to go.
* it wasn't recognized by the phone or Windows. Only the Lexar formatting app could access it. After a low level format it was visible to the phone and Windows.
Really?
Well I said I would let everyone know the progress. Simple terms FAIL.
6:00AM this morning the error came back. ( SD Card was removed unsafely )
So I guess now I'll try the new SD card I mentioned above or the one mentioned above by Blackhawk ( Thanks for the info. )
(SanDisk 128GB Extreme MicroSDXC U3, V30, 4K, A2, Micro SD.)

Well .5 tb will be nice to have.
I hope this works...
Format in phone.
I would leave the card in the phone and up/download data via the phone rather than removing the card to do so.

Found another interesting read. Maybe Android 11 is the issue.
Reading through this post I see the Scandisk Extreme SD card has issues to.
problem with "sd card removed unsafely" notification
hello, can you guys help with this issue? looks like it is not just an A72 problem, but also on other models. the notification is very frequent, and happens even while the phone is on standby. what i tried so far a 128gb sandisk extreme pro...

I have no love for 11 and running on Pie quit happily on my Note 10+.
Can't say that Lexar card is know good for your phone because it uses a faster and different memory controller as well as the imfamous A-11 OS.
However before blaming the hardware or firmware I would give the Lexar a shot. It's a nice card to have regardless.
Well I picked up the sd card member Blackhawk was talking about this morning. A Lexar High-Performance 633x 512GB MicroSDXC UHS-I Card. I put the card in fresh out of the package let the A52 format the card about 4 hours later same as before, the fault came back. After reading the post the Blackhawk wrote about his pie made me think I'll try that. Fired up my pie4 and let the pie4 do the format. Well no luck there either within 30 minutes the fault came back. Well now I know its either the A52 or its Android 11. The cards both work really well in all may other devices. However the A52 5G is the only thing running Android 11. Now the question is return the phone or wait for Android 12.

Sorry to hear that. I meant that Pie as in Android 9. Try the Lexar low level formatting utility if you can find it. Again, format in phone before you use it to be on the safe side.
It seems it's the phone.
Try clearing the system cache.
Doubt check setting and clear data in associated apks. It still may be something not so obviously obvious... Androids wuv being played with.
Well I finally got the respond for Samsung I was looking for. It's not the SD card but an issue with there firmware. They claim it will be addressed with the next update. I used the Samsung Members App to send them an error report from my device and the response was quite pleasing.
( See there response)
Congratulations, you're a remote Samsung beta tester!
Just sloppy and unprofessional on Samsung's part and no fix... yet.
Eventually they'll get it but it should have never made it out for retail sale like that
Personally I'd consider asking for a full refund as without a working SD card slot the phone becomes a liability for me... as if this little ride hasn't already. That used 10+ is looking more tempting to me.
Wow. Well done
Hi another issue with SD. When I have tried to make a backup on the an SD card via the setting app it stuck after 85% and the result of it I got an SD with "write protection" which I can't change not via DOS not with other 3rd party tools. by the way its working on Samsung tablet including format and copy files but when I put is back to my mobile or try to check it on PC to delete the portion or make any change it still same issue "write protection". Would appreciate any idea before I put it to garbage. Thanks
