MicroSD card losing connection with phone = MTP issues on JB 4.1.1 official release

Every time I flash anything based on the official JB 4.1.1 release, my 32GB MicroSD card (Patriot brand?) freaks out. The phone will say it's "unexpectedly removed" and then adds it back in, and removes it, over and over.
It's happened on all three JB 4.1.1 ROM's I've tried.
I thought my MicroSD was going bad so I low-level formatted it in Windows (hated doing this) and still had trouble. But ONLY with the card in the phone. Windows usually liked the card just fine.
So what I did to resolve it was use Titanium Backup Pro to "freeze" the "MTP Application". After doing that, my MicroSD works great in the phone and AFAIK, I haven't lost any functionality. So I'm not sure what the "MTP Application" is or does, but so far.... so good.
This post is just a heads up to others, in case anyone else runs into this problem.
Or in case anyone wants to tell me WTF is wrong.

Ive had this issue as well twice. Both times I had to format the sd card in my pc and it will work fine for a while. Im curious to know if you are using es file explorer? Im thinking it might have something to do with this issue.

Nope. Never.
Root Explorer + TWRP (if that matters).

Hmm come to think of it I just recently purchased root explorer about the time all this started but surely an app couldn't cause this issue? Heck I dont know it happens so random it hard to pinpoint the problem thats causing it. If I figure it out I will let you know

Ive been trying to duplicate the problem all day with no success. However I have froze the MTP app so maybe thats what the cause is? Would you happen to be using a sandisk micro sd? Because I am..

Ahh hah I duplicated the problem on my phone anyway. I used the my file app to move a rather large file from the internal sd to my external sd and afterwards it lost connection. I had to remove the sd card and install it several times to get it to mount back again. Im not sure if its the moving of the file or the my files app itself that is doing it. I also noticed the media scanner isnt running after moving the file. So I hadnt pinpointed the exact cause but im dang sure getting closer. And I dont think its a bad sd card because I tried another and it did it with it too

You were able to duplicate it even with MTP frozen?
Wow, I have yet to recreate the issue with MTP frozen.
My SD is a Patriot brand. Purchased at Fry's Electronics.

Yea it happened with MTP frozen and unfrozen. Ive tried freezing the my files app and every file explorer on my phone. I just cant put my finger on the cause it happens so random. But it seems me and you are the only ones having this issue so im wondering if we didnt get a bad flash when we updated. When I updated via kies it did not do a full wipe update it did what is known as a dirty flash which I never do because you end up with issues like this. So if we continue to ask each other questions we will eventually figure out what the common link as far as if its an app we are using and things like that.
So did you update via kies or odin?
If you updated via odin where did you get your firmware file file from and if you used odin was it odin on the pc or mobile odin?
And was your update a full or a dirty flash?
We are gonna figure this thing out one day lol.....
Edit.... well apparently we are not the only ones having this issue. Over on droid forums there are several s3'owners most on t mobile but anyway it appears there are a few phones out there with this problem and the only fix is to replace the phone and sd card because the phone ruins the card by unmounting it without stopping it first. My phone is still under warranty so I will be calling ATT tomorrow for them to replace my phone and throw a fit for them to replace my micro sd. I paid 48 bucks for this card and I think ATT should replace it since their faulty phone ruined the card

Wow.
I had the problem with two or three different ROM flashes. So it wasn't just one ROM flash.
Each time, freezing MTP Application has resolved the issue for me.
I'm going on ~4 days now with my current ROM and no more issues since freezing MTP.
Maybe there are a couple different SD card related issues out there.

I had the same problem with ADATA and Kingston brand sd cards. I tried the Sandisk 8GB from my old phone and no problems so far.

Freezing the mtp app has seemed to slow it down. The only problem with freezing mtp is that is how the phone mounts to the pc. Mine just did it again but I unfroze mtp to hook my phone to the pc and right after I backed some stuff up and unplugged it, before I could freeze mtp again it unmounted the card. Ive also tried several different sd cards and several different sizes even tried a 2gb Samsung card with the same results. Im thinking hard about going back to ics to see if that will resolve the issue. ...

I found that my 64GB card was not recognized by the newer kernels - when I use the older kernels or stock, it is recognized, otherwise, the ROM attempts to read the card, and then states it is 'ready to be removed'.

Try reformatting the 64gb card to a fat 32 file system. 64gb cards come formatted exfat and some s3's have had trouble reading them. Put it in a pc into the card reader and open my computer. Then right click on the drive thats showing your card. Ex drive E or F. Mine is drive N. Once you right click on it click format and a box will pop up and you will see the box that says exfat. Click the drop down box and change it to fat32 then click format and your done. Once it finishes put it in your phone and it should recognize it...

Well my 64gb micro sd came today from Amazon and from what ive read on xda and the net I would need to change the file system from exfat to fat32. So I put it in the pc pull up mini tools partition wizard and it gives me no option to format it, I try windows no option for fat32 only ntfs or exfat so I try a couple of others with the same results. Then I try hp format tool and finally format it to fat32 then put it in my phone and it says its damaged and needs formatting so I do and put it back in the pc and im back to exfat. So it seems to only work in my phone in the exfat format soooo im just gonna leave it alone. Oh I even tried formatting it in command prompt and changing the file format and it fails so now im starting to wonder if thats what happened to my old 32gb card and why I suddenly starting having trouble out of it when I updated to jb is because it was fat32. Maybe this new jb dont handle fat32 well or maybe my s3 dont like fat32. Hell I guess its just a mystery. ....
So I would suggest if your having sd issues try formatting your card to exfat and see if that helps the connection issues

S4 Won't read Sd card

I am stumped! I got a Sandisk 64gb sd card for this. Naturally, it came formatted as exfat. From stock through 3 different CM based ROMs, I can't get this S4 to read the SD card. I even downloaded a partition manager to format it to Fat32. I also wiped it and let the phone format it. Even after that it would read it. I know CM now supports exFat format. I even flashed separately the script from the original thread. In any case my laptop has no problem with the sd card. Any help appreciated.

I have a Patriot 32 gb class 10 that was working fine until s couple of days ago. Then the phone said sd card unexpectedly removed. Pulled battery and card nothing. Did a format still nothing put that card in my Asus transformer tablet. read just fine took the card thatvi had in my tablet without formatting it put it in my s4 and it read it. this is my 4th galaxy device they should have figured this out by now. Any suggestions.

same happened with my 32gb on my note2 and now in my gs4

The sudden unmounting and/or sd card not being recognized by the S4 and other devices as mentioned is a known issue that is usually SD card related. Sometimes it's just a matter of reformatting your card to Fat32 if your ROM cannot read exFAT cards.
But if that's not your issue or you already reformatted your card to the appropriate format, the SD card has failed and warranty/replacement is suggested.
Can happen to SanDisk cards in addition to other manufacturers.
You may hear this issue being associated to SanDisk cards if only because they are probably the most counterfeited card out in the market. But the issue can occur to non counterfeit cards also.
To reduce your chances of having theses issues happen, always get your cards from reputable sources, in blister original packaging, etc. And if the price looks too good to be true, it most likely is. Even if you take the above precautions, you can still have issues.
Always back up your data for that 'Just in case moment' in case stuff happens.
Purchasing a card whose Manufacturer and/or Seller has an excellent return/exchange policy is a plus.
Having a spare SD card available can help you troubleshoot what your issue may be regarding a defective card, formatting issue, device issue, etc.

I started to reply to you but my laptop crashed. Seems this s4 just doesn't like that 64gb sandisk. I had an 8gb card laying around and that worked like a charm. The sandisk was foramted exfat out of the box. I formated fat32 and didn't work. I wiped it and left it without format. Put in the phone to let it format the card. It did--fat32 and then still wouldn't read it or even mount it.
I sure don't have anything to lose by trying a different program to format that card. It could come in handy even if I don't use it in the phone. A camera comes to mind.
Oh yeah, it was easeUS that I used to format the card in the first place. Try something else.

Hmmm...
There have been issues with the 64gb SanDisk cards being read by the S4 as well as other devices as described in my previous post, the Ultra cards from what I've read (red & grey) I have the save card, class 10, running without issue on my previous S3 and current S4.
You may want to try the format link above.
You can always purchase another 64GB card on Amazon with a Seller with many, excellent reviews, and go from there, and return what you have to return

Right. That's the very card I have. Thanks for the help.

Anytime.
Let me know how it goes

This happen to me but with my galaxy s3...turned out sd card was corrupted. Good news was Patriot replaced it with a new one....

If the SD card didn't work in other devices I would seek to exchange it. There are other things I can use it in. I just ordered a 32 GB G skill on new egg. That should do it. The other thing I tried on this sandisk is partition it to 2 smaller ones less than 30 GB each formatted to fat32. Finally it recognized one of those partitions. When I get the other card I'll swap them.

I had the same problem as you OP. I've also downloaded programs to change the format type and stuff, but nothing worked, but I fixed it in a weird way.
My 64gb card didn't work on my samsung. I used many programs to format the card to get it to work, but nothing. What fixed it was....
I took that card and placed it inside my old smartphone (LG G2X). Once placed inside, a pop-up promoted me saying my card was damaged and it will try to fix it. I've tried this on my samsung and it didn't fix it, but once I tried it on this old smartphone, the card for fixed and started to work on my samsung.
I don't know if this could help you, but that's how I fixed my problem.

I had tried that already when the device initially wouldn't read the sd card. When I partitioned the card in FAT32 then the device picked it up, but only one partition of 29GB.

I don't know what your problem is, then. My 64GB Sandisk card works perfectly in my Galaxy 4.

I don't know what me problem is either. When I have the time I going to return to stock and start over. TWRP won't backup onto the SD card either. Wondering if its behaving this way because I rooted the phone before putting SD card in. Though I have done complete wipe (including internal memory) prior to installing current ROM.

I have a SanDisk 64gb micro SD card in my S4, and had it ever since I got the phone about 1.5 years ago. now I am getting the issues you all are getting. I have NOT updated to a new firmware version. and I just backed up and reformatted the card. Very frustrating when all your apps disappear. come to find out they are all being stored on the SD card witch is now not responding... I will try a differect card. I wish they would just leave the phone a lot and stop doing so many updates.. they update one thing it screws up another. Ever since the first update my "Drive" app don't work, and they have no clue why.. not even Samsung knows...
oh well

Odd SD Card Response
I have recently upgraded from a ATT Samsung Express (Tracfone) moving my 32GB SD Card into the brand new Galaxy S4 I Knoxed up right out of the box just as a matter of principle. I saferooted the phone and installed TWRP which for some reason refuses to load after a few succesful tries and a backup of my system and restore thern reload of TWRP. My concern in this question (unless some knight in shining armour can make sense of my TWRP issue) is that I am not able to write to the samsung branded SD card I removed from the old phone. I cannot create a ROM directory on it when the phone is connected to the PC, nor can I copy files to it. I had hoped to preserve the photos on the card and suppose I can break down and buy an adapter so it will connect to my PC but the point is it "should" work,, no? I cannot create a directory when the phone is connected to the PC nor can I in ES file Explorer. I've also tried to create a directory in root witth ES and am getting the same error. I just want to get the silly balloons off m screen and get google play to run. I am succesfully rooted. I've tried to reload TWRP with Odin only to get the small print int he uper right hand of the screen then no further. I am able to restore my backups thank God.
This is making me batty on a three step process. The card is my main concern right now as I can't load the ROM to it once I get TWRP figured out. Thanks in advance for all the great help I always get. The better I get the more I'll contribute....I promise.

I'm having the same problem. We are not alone, there are numerous threads in the other S4 forums, like this one http://forum.xda-developers.com/showthread.php?t=2281813&page=14

sd card issues android 4.2+?

okay, i've tried and looked for a similar issue but so far i can't find anything related.
I have a sandisk microsd ultrahc card 16gb.
the card itself works extremely well, both in my device when using the stock / custom samsung based roms,
Didn't really notice this untill i tried out android 4.3, at wich i thought first could be a bug in the rom, the settings kept fc'ing the moment i opened up the storage part, and a com.android.media kept fc'ing the moment i attached the usb cable.
as i thought 4.3 was the culprit i flashed 4.2.2 wich also had similar issues up until the moment i removed the card from my device and restarted, everything worked smoothly afterwards.
I've tried using exfat / fat32 both with cluster of 4096 and 8192 and neither of those helped in any way. Turns out that both TWRP and CWM (yes i tried it in both) also can't seem to mount the sd-card.
Is there any workaround for this issue? or do i have to get myself another sd-card?

I think it's the ROMs man messing things up...i tried android 4.3 yesterday and my whole android directory changed like I had to go into a folder called 0/0/0/my android files. to reach my files etc couldn't mount from sdcard couldn't copy things across from pc...I just flashed back my original stock firmware and everything is good..... android 4.3 is pretty messed up..give it time to mature still very buggy
Sent from my GT-N7105 using Tapatalk 2

The messed up folder i should get used to thoug its because of the multiple user profiles things are getting a bit messy.
Its something they added in 4.2.2 i believe
Best way to do it is to flash the rom and afterwards copy back everything to the sdcard.
Didn't have any issues with another sd card i still had laying around but that thing even thoug class 4 doesn't get more than 1mbps transfer speed.

if the sdcard works on your pc with directly like by using an mmc adapter or sdcard to USB converter then your card is ok if it just didn't work on the phone it has to be a software issue our maybe the hardware mmc port is faulty??!
Sent from my GT-N7105 using Tapatalk 4

thats just it, the sd card works like a charm untill i upgrade to 4.2.2 or 4.3. however both recoveries can't mount the sd-card either.
its not one of those black ones that goes to class 10, but an ultra hdsc class 1 so might be something related to not being able to work properly with anything higher than class 10

nope....the class issue has nothing to do with software.....that's purely the job off the chip electronics/hardware.... I would say a combination of your recoveries and ROMs like I had the same issue once the custom recoveries maybe can't point to the location/ section of the memory card...try changing to different version of the recovery...maybe that could help but be sure the recovery is supported on your device...these are risky issues...so only do it at your own risk
Sent from my GT-N7105 using Tapatalk 4

i've tried several versions of CWM both touch and normal, also philz (yesterday but touch didn't work as it should so won't stick with that one) and TWRP but none of them could mount/find the external_sd, the only think properly working with that sd card is the stock samsung and custom roms based on stock.
(not particulary fond of TWRP, i like the layout and how it works, i just don't like the backups of that recovery, can't copy them to my computer, the extensions keep giving me an error and they are located on the phone's storage)
the sd card couldn't be found in my sensation xe neither i remembered just now after i stopped using the 4.0 stock rom and switched to custom roms, at the time i didn't really see a connection and thought my sd card just didn't want to work properly in my sensation anymore, But having the same issues, and using another sd-card in the phone worked again. Used the ultra sd card in my tabled and because i didn't use that one anymore and someone in my family needed a 16gb one for tomtom europe i gave my good one away )
gonna get myself a new sd-card this afternoon as the 8gb i had laying around isn't getting higher transfer speeds then 1mbps at most even if its a class 4. a shop nearby has a class 10, 16gb for 13 euro's so reckon thats not a bad deal, might even go for the class 10 32gb for 26 euro's if they have it in stock.

I have a 64gig card and had similar problems. With phils recovery it only works when formatted fat32. Think that exfat is not supported. With stock kernel it mounts exfat with any other kernel i tried it would only mount fat32. I think samsung kernel has support for exfat and others dont. So it might not be adroid related but kernel related.

weird thing is though, even when formatted to fat32 and not exfat, android 4.2 and 4.3 will not recognise my card, also the recoveries i only get an error when i want to mount my sd-card
my tablet which is running an aosp version of android 4.0 or 4.1 (can't quite remember) could handle the sd-card just fine, while both my phones have issues with it.
solved it by buying myself a new sd card, ^^ now i can at least safely backup to my external card instead of the internal memory.

What is wrong with my Note 2?! PLEASE HELP

Hi I recently purchased a Note 2 from a guy on craigslist. I checked out the phone at purchase and everything proved to be correct. I didn't expect however that he had the phone rooted. I'm a big fan of rooting phones that don't have a good operating systems already or didn't have Android JB but phones like the galaxy phones I believe don't necessarily need to be rooted. I was pissed because I wanted it with stock rom but I just decided to accept it and unroot it myself. So after a long process I got it unrooted and running the latest stock rom and everything seemed to work except for one thing. When I transfered all of the Music files from my previous phones microSD(16gb) to my new one(64gb) none of the music files worked. All of them wouldn't play and the phone would say it can't open the file or something like that. So I tried formating the microSD and trying to put the files on the microSD again and still the files wouldn't play. I had to format the card through the phone itself and transfer the files through Samsung Kies just for 3/4 of the music to work. I can deal with 3/4 but now when I transfer a video file weather through Kies or straight to the folder none of the files play. When trying to play them nothing shows or sounds it's just black screen, you can fast foward or skip but nothing shows. I never thought I would have this much trouble with this phone but it appears as though there's a virus on the phone or card or something that is preventing video and music files to play. Even when trying to play files from the phone on Windows Media Player or any other music/video player the files don't play. I have also found that whenever I connect the phone to my PC let's say a day after I last connected it, I have to run USB connections on Kies and it has to reinstall the drivers for the phone just to actually see the files on the phone. Please help me I have no idea what to do. Thanks in advance.

You need to flashed a kernel that support exFAT format for 64gb or you can format your 64gb to FAT32 format, but for me i prefer to Saber Kernel and i don't need to format my micro sd card, you could try there are other kernels available for stock rom you can find them here...http://forum.xda-developers.com/showthread.php?t=1987541

So you're saying it's the microSD's format? It has nothing to do with the fact that the phone was rooted and that it might have a bug? Would kind of make sense because when I put the 16gb sd card in the phone all of the music files work. So it's the format, but I need a kernel? I have also found that whenever I connect the phone to my PC let's say a day after I last connected it, I have to run USB connections on Kies and it has to reinstall the drivers for the phone just to actually see the files on the phone. It'll show the phone but it wont show anything inside it just shows blank. Excuse me if I'm coming off idiotic, I have no experience with this phone or 64gb microSD cards lol

Since you're unrooted, you can't flash a new kernel so you may want to dismiss that last thing.
Have you tried only one 64gb microSD? It seems that your card may be bad or it's not formatted correctly for the stock firmware... I would test out another 64gb card and see if that works since the 16 works just fine.
Edit: Sorry... a little vague... the card needs to be formatted as Exfat if you can do that through Windows, that should work in case the card is actually in good condition.

Have you tried only one 64gb microSD? It seems that your card may be bad or it's not formatted correctly for the stock firmware... I would test out another 64gb card and see if that works since the 16 works just fine.
Edit: Sorry... a little vague... the card needs to be formatted as Exfat if you can do that through Windows, that should work in case the card is actually in good condition.

I don't have any other 64gb microSD cards, the one I have came with the phone. The logo and everything on the card have faded out so I don't know what brand but I think it's sandisk. I don't know at this point I'm thinking it has to be the card because I've tried nearly everything and it's still not working the way I want it to. I formatted it using Windows UGI to FAT32 since thats what you said and that was the same format as the 16gb and sure enough most of the music works with some not working. So I tried putting movies on the card and once I didn't see a preview on the bottom left I knew it wasn't going to work. Seems like the card is bipolar I have a 32gb micro I'll try that, it's brand new still haven't used it, should I just put it in and see if it works or should I format it to FAT32? By the way Thanks again really appreciate your help!

Try formatting to Exfat... it doesn't hurt to try at this point.

I think he mention phone is rooted sorry if misread that part thats the reason i recommend to flashed kernel that support exFAT, actually as far as i know 64gb microsd card default format is already exFAT and 32 or 16gb is FAT32 and some are in exFAT. If doesnt want to flashed kernel then i recommend format sdcard from computer just plug in from card then right mouse that drive then format and select FAT32 format. If some instance your computer can't read your microsd card and cant format there is chance thar your microsd card maybe bad.

If you can see the files in the player, and you can see the sd card directory using a file explorer, its not the card. I had to add two lines to my system settings file. I'm sorry I don't remember the file name or the content of the two lines. Maybe my comment will jog someone's memory.

The phone is not rooted, it's running stock rom. I've already formatted the card a million times to exFat and still didn't work.

I can see the files but they do not work, At this point everything is leading to the problem being the card. I mean my other SD cards work with the phone and have no problem playing music or video files. I've tried nearly everything and the card still continues to malfunction.

I've formatted it to exFat a million times. That what I originally was formatting it to because windows quick format doesn't have a FAT32 option only exFat which was default and NTFS. exFat is not the problem.

It's looking more and more like SD damage...
Considering the fact that other cards work fine...
Copy your media to PC from the SD...and get a new card ?
I know it sucks...
And once the new card is installed...be "very" careful moving those files back as they may be messed up...
I'd pull a few songs from the PC after you copy them over and test them on another card to be sure before loading it to a new and expensive SD...
It sounds like the phone is fine...g

Try to format to NTFS first then format to FAT32 if doesn't work then maybe a bad microsd card

Hummmm, as what the younger people say....REALLY?!?!?!? which I have found has lots of meanings.
really → a question, as an exclamation of dismay, disapproval, doubt, surprise, etc.

I'm not being a scumbag. The card works it's just has some problems but it works. I mean I don't know how the card would react on another phone or maybe someone would use it as their card for their camera I don't know. You're acting like it doesn't work at all and I'm going to try to screw somebody into buying a defective card.

64gb micro SD problems

I'm running Jasminerom 4.0 and I cannot get 64gb micro sd cards to work properly on my VS985. If I format via settings, it defaults to exfat. Performance suffers and I seem to get random corruption of files. I've tried formatting to fat32 via TWRP and via Windows. Performance is better for a bit, but in time the phone starts not writing to the card for some reason. I've tried 2 different cards, Samsung evo and SanDisk ultra. I'm currently using a 32gb SanDisk ultra which works as it should.
Any others have this problem with 64gb cards?

Yes i have this problem too. I somehow semi-repaired files corruption by formating the 64GB card with Easues partition manager. Format it with this program as FAT32 and see if it helps.

Thanks I'll try that and let you know how I make out.
Using a 32gb card is an ok workaround but this problem really bugs me. I'm hoping the lollipop update might fix this issue. We'll see...

Like mentioned above, formatting your card to 2x fat32 partitions should fix it. The problem is with exFAT. I doesn't see it as a removable memory and ends up getting corrupted, sometimes, a reboot will fix it but after a while, it needs a fresh format.
I'm thinking the problem is with the kernel as stock didn't give me issues, could be wrong though. I know CM broke it last week so ROM that are base off it would have it broken as well but could be fixed by now.

I used Easeus to format to fat32. The card worked great this weekend.
This morning I checked for some files and several entire directories had been deleted. Looks like I'm having the same issues as before, and I really don't know what is triggering it. I'll stick with my 32gb card for now.

has anyone found a solution for this I've bought several different top of the line cards, anything over 32gb stuff gets corrupt.
appreciate any help, thanks in advance
