What's the monitoring app that everyone is using? I've just been watching for the previous symptoms (message when I wake up the phone).

At least on my devices (other than my EVO 4G), the SD Tools app defaults to displaying info for the internal memory -- not the ext SD card. For example, it tells me that my my "SD card" is only 12GB (instead of 32GB) and says it's a Samsung, even when I have the SanDisk card in.
[T-Mobile Samsung Galaxy Note II] cooleydub:
I have a pny 32 gig sd hc and the same problems started right away same day I put it in the phone. Now I can't get the phone to even recognize that there is a card in it.

I am using this app - SD Monitor.

--> play.google.com/store/apps/details?id=com.sdcardmonitor&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5zZGNhcmRtb25pdG9yIl0

To be honest, the error sometimes pop up even in sleep mode and I was totally unaware of it till I open that app to view the no. of bad removal. U could just be lucky that the error didn't appear upon u wake up your phone. This app is really useful. Trust me, u will be surprised with no. of removal detected while phone is hibernating. I will try to attach some screenshots of the error soon (if possible because I am not allowed to attach pictures as new user)

Mine shows the the name and OEM ID but I have no idea about the abbreviation. As long as the app (SD Tools) allows me to perform a read/write test, I am fine. FYI, below is the data of the 32GB incompatible Sandisk card info;

Name: SU32G

OEM Id : SD

Mid: 0x000003

Date: 10/2012

Serial : 0x1cd69d12

Firmware: 0x0

Hardware: 0x8

Ok, I'm now running SD Monitor, so we'll see how it goes.

One problem that I could see with that is I'm no longer using my sd card for any music files or custom alarms - I moved all those to internal memory after getting burned on music alarms and reminders to many times when this problem first started up. One theory about the problem is that with multiple Spa using the same files/filets on the SD card, maybe that's causing a glitch-ish problem from the Jellybean update or something??? Who knows... anyway, so until I move my music back to the ext SD this problem may not resurface. We'll see. I'll report back in a couple of days or sooner if the app reports an unmount.

Oh yeah, I never get that info from SD Tools on any ext SD card I put in my Note2 -- It always just shows the same info about the internal memory that I get even if I have no ext SD card in the slot when I run SD Tools.

Is there a newer version of SD Tools than what's in Play? Like here on XDA or something? I'm running (I believe) v1.0 downloaded from Play.

Try out a 16gb sd card and see if it helps

---------- Post added at 01:43 AM ---------- Previous post was at 01:12 AM ----------

Great, do keep us updated. As of the 3rd day, no bad removal found on my 16gb Sandisk Ultra Red/Grey sd card. The technical support from Samsung told me no problem using 32GB card. Until someone really uses a genuine Samsung Sd card and provide some update, I will not use 32 GB sd cards for my S3 LTE.

I am using SD tools ver 2.9 and I downloaded from Play store. Is it a different Playstore from my country, Singapore.?

Sidetrack this topic a bit. Another problem found on my S3 LTE was the long charging time. It took me 8 hours to fully charge from 10%. All this happened after the recent JB update. Charging becomes erratic for those on S3 especially LTE. Rest assured, nothing is wrong with the battery, phone or charger. The problem lies with the cable as it has only 4 gold pinouts at the micro USB Side.

For the non LTE S3, it comes with 5 pinouts at the micro USB side and after using it, my charging time reverted back to just 2 hours of charging. I am unsure why there is a difference in the no. of pinouts between s3 and non lte s3 cable. Even for note 2, it's only 4 pinouts and not 5 but I believe the output (2.1 amp) of the charger already compensates the time required to fully charge the battery. That's why I don't see many consumers complained about this issue.

Hopefully this info benefits anyone with charging issues.

Cheers,

P.S. : hopefully Samsung comes up all fixes for JB firmware.

I got my Samsung 16GB card (UHS-1) two days ago and so far the, problem seems to be gone. But what I also noticed is, the phone reads any data much quicker from the Samsung card than from the 32GB Sandisk. I have a video folder on the card with some 80 videos in it and with the old card the video player could not show thumbnails properly (they were static). Now, they are all running as they should. Same thing with the picture folder, as I've noticed much more fluent picture sliding.

I don't know if this comes only from the diference between the classes of the cards (Class 4 SDHC vs. UHS-1), or do Samsung cards for some reason generally work best with Samsung phones.
[T-Mobile Samsung Galaxy Note II] internetpilot:
Well, so far no bad removal for me on my Patriot 32GB Class 4 card. I did get one mount report after I used Titanium Backup to import a backup from the external SD card, but that's not an error. Again, I'm still keeping my fingers crossed (and my SD card photos backed up to my PC), but it would appear so far that at least one non-SanDisk 32GB card is working.

I don't know where I saw v1.0 for SD Tools, but when I checked what I downloaded from the Play store again, it was v2.9. But it still will only show the card info for the internal SD card and not the external SD card, even after changing the path.
[T-Mobile Samsung Galaxy Note II] thundermuppet:
I have this problem but I only got it when I flashed any jelly bean Rom. it works perfect when I use any ics Rom.
[T-Mobile Samsung Galaxy Note II] internetpilot:
Just an update, the SD Monitor app reported a card unmount and card ejected for my Patriot 32 GB Class 4 card. I was doing a lot of Titanium Backup restores and imports/exports, so that could explain it. These weren't labeled as bad removals, so it's probably nothing to worry about... yet.

---------- Post added at 11:02 AM ---------- Previous post was at 10:38 AM ----------

Actually that seems to be what happens when I reboot my phone, so not a problem.

Samsung needs to address this.... This problem isn't going away...

I have had no issues w/AOSP and a SANDISK 64. Its FAT32. the card has not been used with TW at all.

[T-Mobile Samsung Galaxy Note II] Sidneymac:
Why don't people just reformat to something else ? Instead of fat32
[T-Mobile Samsung Galaxy Note II] RonnieRuff:
AOSP only supports FAT32. Some TW ROMs support XFAT.

Sent By An Idiot With A Phablet!
[T-Mobile Samsung Galaxy Note II] internetpilot:
Because that isn't necessarily the problem. It seems to be rather specific to one namebrand, size, and class of card. I'm still not having any problems with my Patriot 32gb Class 4 formatted with fat32, whereas I was having problems with my SanDisk 32GB Clad 10 UHS1 red/grey card.

I still suspect a hardware incompatibility between Samsung and SanDisk.
[T-Mobile Samsung Galaxy Note II] Android Revolution:
I've had these same issues on all my Samsung phones, with Patriot Class 10 16GB cards. It's not an exclusive issue to this phone or SanDisk.

I am now using a Samsung Class 10 32GB and haven't had a single issue.
[T-Mobile Samsung Galaxy Note II] internetpilot:
Patriot doesn't actually manufacture their own memory cards (at least not the guts). Who actually makes the components of that particular model of Patriot memory card? It could very well be SanDisk.
[T-Mobile Samsung Galaxy Note II] RonnieRuff:
When there is incompatibility with hardware it would not be so intermittent across devices. It is more likely firmware.

That's what I'm thinking. I was running 4.2.1 and using my 32gb sandisk just fine up until recently when 4.2.2 was released...
[T-Mobile Samsung Galaxy Note II] internetpilot:
Except it doesn't seem to be so intermittent -- most people posting about this problem are using a very specific model of SanDisk card.

I'm a 20-year career network engineer, and I've seen plenty of hardware incompatibilities take longer to show up than this. Even so, hardware incompatibilities are typically fixed via firmware/software, so the solution will likely be the same and need to come from Samsung.
[T-Mobile Samsung Galaxy Note II] wbd:
Just thought I'd add to the discussion my experience with this problem.

Grey/Red SanDisk 32GB Ultra U1.

S3 with stock ROM, unrooted.

Was working perfectly well for over a month under 4.0.4 and then 4.1.1, but as soon as 4.1.2 was applied, the problems began.

Have tried 3 different stock 4.1.2 ROMs, but the problem persists.

I think it's firmware related (specifically 4.1.2).

Hopefully it will be acknowledged by Samsung and addressed in a (very near) future release.

EDIT: Given that the card was working before the JB upgrade, I don;t think it is related to the thickness of the card. I am going to try the Protect SD card setting instead - will report back if/when anything happens.
[T-Mobile Samsung Galaxy Note II] wbd:
Well, the Protect SD card setting has not stopped the ongoing SD Card unmounting/mounting.

Have been running SD Card Monitor app... and assuming that it actually works as intended, the only interesting information I have discovered is that when the phone is not connected to mains the incidence of unmounts/remounts skyrockets.

Example: Unplugged my phone last night when I went to bed (11:00pm), left it sitting on the desk and when I checked this morning at 6:15am, the app was reporting 157 unmounts - that's more than one every three minutes!! :eek: (For the record, the unmounts were - from what I could tell - at random intervals and not evenly spaced apart.)

So I plugged the phone in for recharge at 6:15am (still sitting in the same place on the desk) and since then (three hours), not one single unmount. FYI, I plug my phone in to the laptop to charge, not directly into mains.

Anyone else able to test to see if the SD Card issue is more prevalent when their device is not plugged in? If we can get some correlation it may assist in diagnosing the cause of the problem (and hopefully identifying a solution).
[T-Mobile Samsung Galaxy Note II] kemin:
Same thing happened to me when I upgraded my Galaxy S2 i9100 to version 4.1.2 (Neat Rom 4.3 and 4.4). I've got a microsd Sandisk 32gb (r/g) class 10.

I tried, without success, to:

- changing rom (it work only with ics or earlier rom)

- changing kernel (i tried stock, philz, siyah)

- formatting microsd with device

- formatting microsd with "sd formatter"

I noticed that sd card works when I use the phone or when the device is plugged for recharge.
[T-Mobile Samsung Galaxy Note II] Android Revolution:

[T-Mobile Samsung Galaxy Note II] Sidneymac:
Its probably 4.1.2 then since I noticed the change aftee updating...Its time we get a 4.2.2 for TW roms.

I havent had any sd card issues but my wifes tmobile gs3 has chewed through 2 of them thus far.
[T-Mobile Samsung Galaxy Note II] farfromovin:
I've been getting these recently. I'm using a Kingston SD card modified through a microsd adapter. Anyway, the end of my adapter that is inserted first into the microsd slot is a little worn. I've noticed I can move the adapter while it's inserted and get this error message. My guess is "small" cards. I really think it's a hardware issue. Actually, I'm just trying to think of a good material to "wedge" in the micro sd cage to tighten things up. My guess is that will fix it.
[T-Mobile Samsung Galaxy Note II] arctic84:
As i'm taking my TPU cover off of my phone, it'll flex the phone slightly and the unexpectedly removed error will occur. (samsung 32gb microsd)

I also believe it's a hardware error, if not with the aluminum slot itself, possibly some hardware connected inside which moves around. :(

I want to try the samsung 64gb to see if the actual thickness will make the difference, but it's far too expensive at the moment..

I'm surprised no one has started a petition of some sort considering this isn't limited to the t-mobile version, as someone else stated it also occurs with the verizon model.
[T-Mobile Samsung Galaxy Note II] internetpilot:
And the Sprint version.

I'm also pretty sure it's a hardware issue.
[T-Mobile Samsung Galaxy Note II] william58:
I have a AT&T Note II & Tab 2 and had gotten a new microSD 32GB card for the Note II and considering getting another one for the Tab 2.

However it was brought to my attention in another post on AT&T area of these problems, So, I took my MicroSD 32GB card back to Best Buy and talked to the head tech guy and he said he hasn't heard any problems at his store yet, but said it could be very possible as this was a newer card that is totally new and may have some bugs in it that is just now surfacing.

Said these below were much more reliable for the moment:

PNY Technologies - 32GB High Speed microSDHC Class 10 Memory Card

Sale: $29.99

Reg. Price: $79.99

You Save: $50.00

I bought two for that price for my Samsung Galaxy Note II and Tab 2.

Hopefully no problems.

Anybody here used the PNY cards?
[T-Mobile Samsung Galaxy Note II] JesseMT4G:
I have an s3 and have had 3 cards do this on me. It seems anytime in my instance I do an OTA update, the next day or few days later the Sd card goes to crap. I lost a lot of pictures one time, so make a habit to back everything up on the computer.

Have had an old card in for the last few weeks and no issues, only 8G and been solid.

Will make a habit to take the card out when doing OTA updates or adding a different ROM.

just my opinion, from my experiences.

I am using the red/gray sandisk Ultra microSDHC 32gb class 10. "SD card removed" started happening maybe a month ago and it was very intermittent. Nowadays it pops up nearly every single time i wake the device. Battery life has drastically decreased because of the constant scanning of the card. One time it even said "damaged SD card" and prompted me to reformat the card.
[T-Mobile Samsung Galaxy Note II] internetpilot:
Well, I guess I can now say that it's the SanDisk card that is the problem and not even a combination of the SanDisk card and a Samsung phone. The card is starting to crap out in my Acer Iconia A500 tablet with six bad removal notices just today alone. I'm going to contact SanDisk and tell them I want a refund. I'm pretty much done with their cards. Everyone makes a big deal over them especially in the photography world, but I've been less than impressed. Now they're pretty much over priced garbage.
[T-Mobile Samsung Galaxy Note II] arctic84:
My samsung 32gb microsd has this problem. (it worked flawlessly on my gs3 and every other phone)

Just picked up the 64gb microsd by samsung (since sandisk seems to be a POS)

So far so good, will report in if issues begin

my girl and my friend both have our phones using 16gb and 8gb cards and they're just fine.. so i'm starting to think it maybe related to 32gb cards..?
[T-Mobile Samsung Galaxy Note II] luismedina:
I started with this issue a couple of days ago.

I'm using a Sandisk 32GB class 4 microSD card since 2 months ago and no problems whatsoever. The issue happens even with the screen turned on and music playing, Poweramp is not able to read the files but after the card is mounted again everything goes back to normal, also, Storage is reporting over 12 GB for pictures and videos, which is wrong because all of my pictures are in my SD card and I only have around 740 pictures for the camera folder.

I've tried everything in this post, even move my pictures to the internal storage to figure out if i could resolve the issue with the Storage report but i've had not success.

I have the exact same issue. Same card but using Galaxy S3 LTE. The card worked fine for 3 months, then a few days ago I got the exact same messages as above. It happens when I pick the phone up from the table etc. Reformatted it on the PC and on the phone, but the problem persists. Help please.
[T-Mobile Samsung Galaxy Note II] arctic84:
Follow up

Okay, so it seems this issue isn't related to a specific card. I purchased a 64gb samsung micro sd the other day and it seems to have this issue again.

For some, it's much more sporatic.

For me however; it happens when i'm applying pressure to the back mid area of the phone, pretty much where the sd card is. And then if I apply pressure to one of the top two corners of the phone, it seems the slight flex in the phone's chassis will cause something to lose connection with the SD card. It also happens when I have the phone in my armband since it is duplicating the same sort of pressure.
[T-Mobile Samsung Galaxy Note II] BTT8:
Just had a sd card eject with my Samsung 8gb card over night. Not cool.
[T-Mobile Samsung Galaxy Note II] Crescendo Xenomorph:
OK, seems I understand the issue, and seems also that I cornered the issue.

First, the card is working normally while DEVICE ISN'T SLEEPING.

Second, it happens mostly while WE'RE SLEEPING AT NIGHT or WHILE THE PHONE LEFT DEEP SLEEP (Paranormal Activity? LOL)

So, based on this: something in kernel/ROM/anything that control the power to SDCARD doesn't provide correct/adequate voltage or electricity to the SDCARD while the phone in DEEPSLEEP.

Or: the card don't want to be suspended in deepsleep, it just removing itself when instructed to sleep (this one is the card's fault).

And: any card thats been badly removed thousands times (it can do around 20 bad removal at 7h period so, count it yourself), its become broken/unusable but not fried as stated in many site). The chip broken,yes,but due to bad removal thousands times....

So, any response and research is needed on this.

Also disassembling the device to re-plug the sd/sim module flex inside doesn't help at all.

SD Card unmounting issue - has it been resolved?

I've just bought the SGN2 and was about to buy an SD card - jury suggests that the best advice is to avoid the SanDisk 32gb variety but my question is ' has the problem been identified' and if so what is it?

[T-Mobile Samsung Galaxy Note II] joetico:
Hi there. I don’t have a note II, but I have been dealing with the same issue with my galaxy s advance, running gingerbread. I have the 32 GB class 10 sandisk (red and grey). I noticed I did not get the issue after performing a factory reset, I could confirm this twice. The problem came back once I installed a 3rd party music player or installed any app on the SD. I guess the problem has to do with some kind of media/app index the phone has. I noticed that the first time you load the SD card after the factory reset, the media scanning is very slow, but the album thumbnails from the music app load really fast. After the issue appears, the scanning is faster but the album thumbnails take a long time to load after you open the app. Sorry for posting this here but I couldn’t find a thread for my phone and I am really sick of this issue. Hope this helps
[T-Mobile Samsung Galaxy Note II] superdookie67:
Wow, I'm glad I found this thread. I noticed the messages when I turn on my phone too. I just assumed it was some battery saving feature of the rom that I was using.

I had this problem on my SIII with a Kingston 32G Class 4 card.

What failed:

1. Changing kernals and ROMs

2. twrp / goomanager / open recovery script

3. Setting SD card cache

What worked:

Thanks to the SD card monitor app, it was obvious that this problem only occurred when the screen was locked. It unmounted / remounted every ~3min, which drained the battery really fast. So I suspect it's caused by the phone's sleeping mode. After trying out a few apps, Wake Lock app did the job for me. Download the app from Google Play and set it to PARTIAL_WAKE_LOCK to keep the CPU awake constantly. Of course it consumes battery too, but way better than the SD card did before. Now the card never gets ejected and the battery can last more than 10hrs in normal usage.

Samsung Galaxy Note + SanDisk Ultra microSDHC 32 GB Class 10 + Android version 4.1.2

Hi!

I have a Samsung Galaxy Note with SanDisk Ultra microSDHC 32 GB Class 10

It was working fine until last week when I upgraded to the latest Android version 4.1.2 and since then I constantly have issues with my SD card. It gets unmounted unexpectedly, then mounted again etc.

I can confirm:

My card is SanDisk Ultra microSDHC 32 GB Class 10 (red/grey)

It was working fine since Septmber 2012 until April 2013

Issue started happening only and immediately after upgrade to Android 4.1.2

As well I tried to set developer flag Protect SD card but it did not improve the situation.

The issue seems to be related to sleep/eco-power mode.

My observation point to some incompatibility of Android 4.1.2 and SanDisk Ultra microSDHC 32 GB Class 10

I opened support messages both with Samsung and SanDisk, and would try to update you as soon as I have any feedback from official support.

Cheers!
