Micro SD Card Unexpected Removal causes TouchWiz Home to have problems - Galaxy S 4 Q&A, Help & Troubleshooting

Hi XDA,
I have a problem with my Samsung Galaxy S4 LTE I9505. Sometimes, after I formatted my micro SD card to exFAT, about 2 to 3 days later the dreaded "SD Card Unexpectedly Removed" error shows up in the status bar. It's kinda annoying to see that message as sometimes the phone will not remount the micro SD card at all. That's when I have to re-plug-in my micro SD card back into the SD card slot in my Mac using the micro SD card adapter that came with it. Then I have to go through the formatting process again.
Before that, I backup all my files that are stored on my micro SD card to my external hard drive via my Mac. Following which I format the card. The same problem surfaces again after 2 to 3 days, like I said in the first paragraph. Is there a permanent solution for me to solve this issue? I am planning to replace my micro SD card with a Samsung SDXC 32GB class 10.
Also, I would like to add in that, when the micro SD card is unexpectedly removed, sometimes that issue causes a "software glitch" with TouchWiz Home. After about 2 seconds the TouchWiz Home launcher refreshes itself (NO REBOOTING INVOLVED) and this happens until I power off the device. When I boot the phone again the problem is solved. However, 40% of the time the "SD Card Unexpectedly Removed" pops up and if I'm lucky, the phone will automatically detect and remount the micro SD card within 10–30 seconds. Other times, I have no choice but to take the card out from my phone and re-format it.
I need my micro SD card to be in exFAT as some files I have stored in the card are larger than 4GB. Can an XDA expert help me with this issue?
(I do not want to perform a factory reset as that wastes a lot of time. I've tried that and the issue keeps on coming back.)
MANY THANKS! WILL CLICK ON THE "THANKS" BUTTON IF SOME XDA MEMBER IS ABLE TO SOLVE THIS ISSUE! :good::good::good:
UPDATE: There are compatibility issues (I had) with the SanDisk Ultra 16GB Class 10 SDHC card.
There seems to be an issue with Samsung's latest phones (i.e. Samsung Galaxy S3 and S4) using SanDisk's micro SD cards. Every 4 hours or so, my Galaxy S4 would show an error in the notification bar, saying "SD Card Unexpectedly Removed", and then "Preparing SD Card" (or sometimes "Preparing SD Card" does not even show up!) I always had to plug the card in to the SD card slot of my Macbook Air using SanDisk's micro SD card adapter and re-format the card. I've tested both FAT32 and exFAT and both posed problems. I gave up on the micro SD card and decided to buy a new Samsung Plus 32GB SDHC UHS-1 class 10 card. No issues for now (I tested FAT32 so far for my new Samsung micro SD card, will test out exFAT). Will report if there's a problem again tomorrow.
My advice: for those who are having problems with their SanDisk micro SD cards, please switch to Samsung's very own Plus or Pro series of micro SDs.

I had this on my original s4 (i337) when using Touchwiz. I installed GPE on it and the problems went away. If I were a betting man, I'd point more towards TW than the SD card itself. I sold my i337 and am now on the i9505G and using thee exact same SD card with zero issues.

I had this same problem before, but after I rooted my phone and installed custom rom this problem is gone. I have the Sandisk 32gb and s4 I9505.

I have the same problem. I have an i9505 with Android 4.3 (which updated yesterday to I9505XXUEMK8 baseband). I've had the problem from new when it was on 4.2.x but thought it was the card (cheapo from HK). Now using a 64gb Samsung with same problems. Did it 3 times today and it's getting tiresome now.
It's still under warranty so I ponder whether to do this root thing and update to KitKat/or other PGe or wait for official KitKat or a fix. Or speak to Samsung for an idea.
The phone isn't locked to a network.
Anyone offer some advice?
Thanks
Mike

SanDisk 32GB Ultra card here.... I made a similar thread recently.. My issues where similar yet somewhat different... However I fixed it all by uninstalling DropBox updates and disabling the bloatware version with Root App Delete.... Sounds completley unrelated, I know, but seriously try it out, it worked for me, and others in another forum too...

Same problem with my San disk ultra 32gb, constant unexpected removed sd card error so my apps r useless most the time as I have most on there,
I've got a lot more issues with my s4 as I posted today I was thinking about ringing samsung up
Sent from my GT-I9505 using xda premium

I know this thread is old but when I had the S4, my 64gb card would give me fits.
I used the sd card formatter from sdcard.org to do a full overwrite format. Then used the S4 to format the card after installation and voila. .... no more issues.
I got the idea from using that tool for the sd cards i use in my Raspberry Pi.
Hope that helps.

[Q] i9500 S4 unsupporting Class 10 SD card

Hi,
I've recently purchased a SanDisk Class 10 32GB SD card for my SAMSUNG S4 i9500.
I have transferred some images and music from old SD card to new one and everything worked perfectly, just until one point when the device just unmounts the SD card and all files seems unaccessible, mounting it again and reinserting the card fixed the problem but it keeps unmounting suddenly, then at one point everything was moved to LOST.DIR. I have formatted the Card to FAT32 on PC then format it again using phone, but still same problem occurring, only now it shows that SD space is being used, still when browsed through on phone, it shows no data at all.
Does i9500 NOT support Class 10, or something wrong with SD card, any body had such experience?

It does support Class 10 cards, I've been using a 64GB Lexar one for about 5 months now with no issues whatsoever.

64GB Sandisk Ultra micro SD cards not working on S5 and Note 10.1

So,
I understood that I could use up to 128GB on the S5.
If this is true, why Can't I use a standard sandisk Ultra micro SD card of 64GB? The menu shows me I can unmount and format, but that doesn't seem to work. I tried formatting in MS-DOS (FAT) format using my Mac (I don't have windows), which worked for my Note 2 but not my S5.
If I try writing a file to the micro SD card it says: "ERROR, could not write file".
When I try to format using the phone, it says no card installed (despite the card being installed, its size being indicated, the unmount and format options being available, etc).
Interesting, I have a second one installed in my note 10.1 2014 edition, and that one behaves a little different. It is also not usable but it greys out the unmount and format options as if the card does not exist (yet still it indicates the available size). Note, for this one I also used the MS-DOS (FAT) formatting method on my Mac.
I know the micro SD cards for both the S5 and the note 10.1 2014 edition are both ok, because I tested them on my Note 2, which reads and writes to the cards perfectly fine.
Both the S5 the tablet and the microSD cards were bought on Singapore Airport.
For info, the tablet runs 4.3 and the S5 runs 4.4.2 straight from the box.
Can someone help me with this?
So I found for the Note 10.1, if I format it with my Note 2, it accepts the card and I can use it normally.
The S5 does not do this, so I suspect this is another major issue with kitkat 4.4.2 (I also have VPN issues with 4.4.2 which I don't have on 4.3)
I have the same card you have in my S5 (it was in my S4 before). I have no issue with the card. But I cannot use other app than the stock file manager to write to it. This is a Kitkat issue though.

i have a 64gb sdhc and i get the error icon on pic and videos when i try and transfer from laptop, phone storage to sd or any type of way the s5 will show the crash icon on the pic and wont view it. Ive used a new 64gb sdxc and 64gb sdhc both did the samething.
I've had 2 of the same genuine SanDisk 64gb cards fail in a similar way on my S3 because I tried to format in Fat32 so it would work with directory bind to move data to external but both times it killed the cards and only a few formatting programs even recognised the card in the end, So this time I'm taking no risks and the card was formatted in S3 then S5 and has gone nowhere near a PC and has run perfect for over a year now.

Just try to avoid formatting in PC because that's where you might get the problems... And anyway I just backup on flash drive through OTG because it saves all that hassle of installing drivers on everything and sitting at the computer or removing the card most days.
I have the same problem here. I have two microSD Samsung 64GB class 10 original (one of these I got on the launch event of Galaxy S5 at Barcelona). Before S5 I had a Galaxy Note 3 and it worked without problems. So I changed my phone to a S5 and both can't be recognized in it. So I bought a 32 GB Sandisk 'cause someone suggest an incompatibility with 64 GB / FAT 32. On the microSD slot, the phone won't recognize it. At USB OTG, S5 recognize only the 32GB... both of 64GB still can't be recognized. WTF?
And yes: all the SD cards can be used normally at PC, W10 tablets...

[Q] Can 16GB internal memory Galaxy S5 use 128GB SD card?

The title pretty much says it all.
My wife has a Galaxy S5 with 16GB internal memory. When I put a 128GB miroSDHX card in it, the phone says the SD card is blank and refuses to mount it.
If I go into Settings>Storage, the only option under SD Card is Mount SD Card. If I tap that, it asks if I want to format the SD Card, If I tap that, I get a message like "preparing SD card" and a couple of seconds later, there is a notification in the title bar of the phone saying either "Blank SD Card" or "Damaged SD Card".
Smaller cards are mounted automatically.
The 128GB card is read just fine by a PC.
Is there something I am missing in getting the phone to recognize the large SD card?

According to gsmarena, the answer is Yes.
Memory
Card slot: microSD, up to 128 GB
Internal: 16/32 GB, 2 GB RAM

It just sounds like your card isn't formatted properly. Probably an unrecognized or corrupt filesystem. Or less likely, out of spec or damaged card. Unfortunately you didn't give any details as to the card model or verbatim error messages so we have nothing to go on.
The card should be formatted as FAT32, not NTFS or exFAT. Try formatting the card as FAT32 on your PC. Mount it on your phone, then reformat again it from the phone Settings menu. If you have ongoing difficulties, check the card for corruption with the chkdsk utility.

I will try formatting on my PC as FAT32, then.
There is no model number on the SD card or its packaging. Just SanDisk Ultra microSDXC UHS-1. 128GB. Speed up to 48MB/s** 320X.
No error messages, either. Just what I quoted from the notifications bar about "Blank SD Card". And in Settings>Storage, there is just one entry for the SD Card: Mount SD Card. Tapping that launches a couple of quick notifications about the SD Card being prepared. Then the notification that the SD Card is blank.
If I pull down the notification bar and tap the Blank SD Card notification, I get a popup to format the card, with OK, Cancel, and a warning that all data will be erased. Tapping OK yields another quick notification about the SD Card being prepared and that is all. And the Blank SD Card notification returns.
*Edit* Just noticed that the PC reports the file system as exFAT. But my PC (Win 8 Pro) offers only exFAT and NTFS as format options.
..
Exfat should work no problem, I've got 64 GB class 10 that's formatted exfat and I've never had issues

Gave up on the 128GB.
A Samsung rep said that the problem was that I was using a Sandisk card and they are problematic with Samsung phones.
So I got a Samsung 64GB Class 10 card.
Same results. The phone reports that the card is blank or has an invalid filesystem. Tried to format on the phone. But no joy. The Samsung card is exfat.
So your phone might have problem with the card reader.

Reader itself is fine. Can mount a 16GB card, FAT32 (aha!).
Went to a VZW store last night.
They could not get the 64 or 128 card to mount. One of them had a Galaxy S5 and the 64 mounted on his phone, no problems whatsoever.
I had him format the card on his phone and tried it again on ours. Same story.
So, after a half hour on hold, I spoke with someone in VZW tech support who at first was adamant that the problem was with the card. I pointed out that the odds of getting two defective cards are extremely small. And asked if the card is defected, how did the card mount in the employee's phone?
His "solution": Factory reset and if the card still does not mount, call tech support back.
Wife said she is tired of the jerkaround.
She will use the 16GB FAT32 card.

128GB MicroSD card - Disappearing files/folders

Hi all,
I have a Galaxy S5 (SM-G900W8) Canadian model. I purchased a 128GB sd card and I'm running into some issues. My S5 can detect the card, and I can copy files to it. But it seems that one I hit roughly 8.08GB of used storage, anything more I add disappears after my phone reboots.
The card was formatted in FAT32 originally. I have tried exFAT but the phone is unable to read the card in this file format. I have also tried NTFS but same results as exFAT.
I have done some research and have seen others with issues regarding 64 and 128GB sd cards with Samsung Galaxy models, but no fix yet (or at least from what I've seen/read).
This card only seems to work in FAT32, but I am unable to use the full capacity of the 128GB sd card in FAT32.
I have a 32GB sd card that works just fine without issues. Not sure what file table the 32GB card is formatted in though as I did not know of this issue until recently when I discovered it so never bothered to check.
Is there a fix for this that I have not found yet? This is quite annoying.
Thanks
Probably a fake.
i dont have problem with Team MicroSD 64GB
you have to format it in your phone (ExFAT), use file explorer in your phone, do not format using PC

What sd card is this because it seems like it's a fake and may not really have all that storage. I've never had any problems with my 64 gb SanDisk micro sd card which I'm currently using.

SD card damaged

Hi everyone,
i have a G900F running on the current version of the ALEXNDR Rom, rooted, Knox 0x1, Android 6.0.1.
I have my SD card formatted as (mixed) adoptable storage (via adb), so I have 50% of space as SD card memory, 50% as adoptable storage.
And now for the problem: The SD card is repeatedly shown as "damaged". As soon as I put it into my PC, it'll work without any problems, but the SGS5 will work for quite a time with it, and then suddenly shows it as damaged and will not mount it unless you format it. It usually happens when a larger amount of data is written to the card.
So I thought that the card might really be damaged (was an old and small and slow one) and went vor a SanDisk Extreme 64GB card - same thing here. Then I read about some problems with Samsung devices and SanDisk cards (may the be true or not, I dont know) and swapped it for a Samsung 32 GB Pro SD card - same thing here.
Does anyone know why this is happening and how to stop it? Or will the adoptable storage just not work?
In addition: I could reproduce this when I was downloading Videos to the SD card from Amazon Prime Video for offline use. Seems that a) this is a large amount of data and b) split into thousands of small files. I dont know if its the number of files or the amount of data, but when I deleted the folder on my PC and put the card back into the phone, it suddenly worked perfectly again. Any ideas on this?
Hey there how are you?
I recently have had an issue with my samsung 128 sd card that was formated in a 50/50 mix from adb too.
As the sd card was formatted in exfat I posted an issue on the exfat home page. https://github.com/relan/exfat/issues/49 I was provided with advice on my mac on how to reformat it using the dd command. This was the only command that I came across which gave me an input output error indicating a hardware issue on the sd card.
I have since purchased a new sd card. I'm thinking of formatting it as either an ext4 format or f2fd format to see whether this makes an impact of its longevity.
Hope this helps.
