Micro SD Card Unexpected Removal causes TouchWiz Home to have problems

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

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.

I am also using Scandisk 32GB Class 10 sdcard but don't have any problems. Why not you try factory resetting the phone or upgrading the firmware. Best of luck...:good:

SD card problems

Hello I have a Bolt and I am having problems with my SD card. I insert it and the phone recognizes it and mounts it as portable storage. I then format the card as internal storage which seems to work ok. Then I attempt to migrate data and the phone hangs up at 0% and never appears to actually migrate data.
I do not think the problem is the SD card, as I insert it into another phone and it works fine as internal storage. I have tried multiple cards in my Bolt and have the same issue. This is the card https://www.amazon.com/gp/product/B01HU3Q6F2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
any help would be appreciated.

You card may not be good enough to format as internal try putting it in and formatting as external I believe it has encryption I had to format card with phone then add my files

Considering this is a UHS-I Card, You shouldn't have any problems.
One thing I will recommend is formatting it twice. Format as internal then reformat as portable, reboot, and reformat as internal and then try migrating your data. That usually did the trick for me. I had issues with these SanDisk Cards though so be careful. I've had two of them die on me already. I RMA'd those and I am awaiting a exchange but I went and got a Samsung SD card as a replacement and haven't had any issues since. For some reason, I've always had to format all my cards twice for adoptable storage to properly work, regardless of device.
Edit: UHS-3. Those Speeds tho ?

I had the same problem until I bought a class 10 SD card now I formated it as internal storage no problem so it went from 32 gig online storage to 64 gigs with the 32 gig expansion using sd card.

Micro SD issue

I'm using G600K.
Inserting SD, the message " This SD card is corrupted, and needed to format" is displayed
However, after formatting, SD card isn't been mounted.
SD card vendor is SanDisk, MITSUBISHI, and SilliconPower
Software ver is G600K10h
Is there anyone who has same problem?

I had the same problem but mine just said it's corrupted and wouldn't format because of this. I then tried the SD card in other phones and it remained corrupted. I hope the G6 is not screwing up our SD cards

I had the same problem my SD card wouldn't work

Only issue I had with mine was when I first booted the phone with it in the system didnt show any stock ringtones or notification sounds. I had to remove the card then reset the phone and insert the sd card after everything loaded. Since then no issues with a PNY card.

My Sandisk card from my G4 swapped over no problem. I deleted a bunch of junk off of it with the G6 and all is well.
