Exclamation 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!

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...

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.
