coincidentally, am experiencing the same thing recently

am pulling my hair off due to it lol
[Galaxy Note II Q&A, Help & Troubleshooting] sagarb:
me to exp the same problem is it because of phone or the card?

Experienced it before... And I flashed a different kernel, it is solved.

Accidentally sent from my Samsung Galaxy Note 2
[Galaxy Note II Q&A, Help & Troubleshooting] rascal123:
Which kernel? Am relief to hear others are having the same problem..I guess it may relate to firmware or kernel since few people are having the same problem..
[Galaxy Note II Q&A, Help & Troubleshooting] pete_n:
Yes, it's been happening to me too when unlocking the phone (and seemingly more recently over the last week).

Using a Sandisk Ultra card and on the standard 4.1.1 ROM.
[Galaxy Note II Q&A, Help & Troubleshooting] livingaboard:
Let me guess, you are all using sandisk ultra cards? These cards appear to be a real pain in the a s s . Mine, (bought new off Amazon in October) went tits up and I believe it was the card that somehow caused corrupted files and caused my "media" process to be a complete battery hog.

About a week before the card totally failed to be recognized by my computer or my phone, I got those random messages about my sd card being unmounted and then it would just automatically scan it as if I had just inserted it when in reality I never took it out. I was able to copy everything to my computer about an hour before it was complete toast

I suggest you copy any important files on the card to your computer or wherever before it completely fails. I don't know what to do about getting a new card. I already filed a warranty claim with Sandisk but I am hesitant to use their brand again. Sandisk seems to be THE brand out there. I would like to try another brand.

[Galaxy Note II Q&A, Help & Troubleshooting] Paul013:
My views on this issue

I have started facing this issue since the past 3-4 days and here are my views that can also serve as valuable information for everyone else:

- This error message started to appear only after I upgraded to android 4.1.2 by flashing the stock rom via odin.

- Im also using the SanDisk Ultra Class 10 32GB card

- I have not rooted my phone after upgrade and my phone is in fully stock condition, although it was rooted before.

- I dropped my phone once. But it was a very minor drop and everything was fine after the drop as it was on 4.1.1 at that time and i was on the same for further 10-15 days and never witnessed the error during these days..

These things should also be considered-

- The method of copying data from PC to phone. I use data cable and copy to the folders while the card is in the phone.

- Whether you remove the card without unmounting it.

I have tried formatting the card from windows using fat32 setting. It didnt help.

Formatted it with the phone and still saw the error once in the past 24hours..

In future, if I encounter the same problem, I might get the card replaced by visiting the sandisk service center here in India. Or, I can try flashing 4.1.1 again and revert back the result. As of now, everything seems to be fine as I have not seen the error for about a day or so.. (Fingers crossed)
[Galaxy Note II Q&A, Help & Troubleshooting] rascal123:
Thats what makes me feel uncomfortable. .if the card is the problem I think my pc wouldn't recognize it or reading the data in it..however it is doing fine with the pc..:(
[Galaxy Note II Q&A, Help & Troubleshooting] noobhero:
and i read pple's card getting fried due to this issue :(
[Galaxy Note II Q&A, Help & Troubleshooting] sagarb:
my doubt is wheather phone is having problem or the card im confuse which service center should i go first samsung or transcend .another thing is today i flashed 4.1.2 india stock rom again through odin now card wont dectecting at all but it is good and recognize with note and my pc

I have the same problem in 4.1.1. Stock, NOT rooted, ever.

Brand new SanDisk Ultra 32GB class UhS-1, bought from the official Amazon store.

Been seeing this problem about the same time since I got official 4.1.1 update from Kies. Formatted it in computer, and in phone, then the problem seems to go away for a few hours, but comes back within a day. What a battery hog, not to mention it can't be healthy for the card!

Trying exFAT format now. Will report back.

Nope, each formatting would stop the problem for a few hours, but it still comes back within a day. :silly:

I have the same problem. Yesterday i have flashed some other ROMs but they did not solved. I'm using SanDisk 32 GB Class 10 as well. While i were using 4.1.1 there was no problem but after the latest update it has occured.

If it worked normel before it means SD cards are okey..

[Galaxy Note II Q&A, Help & Troubleshooting] rickafterburner:
+1 stock everything

+1 this thread. I have a Galaxy Note II - completely vanilla stock, never rooted. I was having issues (don't remember what they were) with the old 16gb card that I was using in another device from a while back and bought the Amazon "SanDisk 32 GB Mobile microSDHC Flash Memory Card SDSDQ-032G-AFFP"

I've been having issues since shortly after I bought it and will contact Samsung.

Thanks for the thread!
[Galaxy Note II Q&A, Help & Troubleshooting] junkoi:
i can confirm this bug with my Note 2. i have the same problem since i upgraded to 4.1.2. the bug appears immediately after the upgrade.

this is definitely the firmware bug, so all the suggestions of replacing the SD card is absolutely wrong.

wondering if Samsung is aware of the problem, and how we can push them to fix it.
[Galaxy Note II Q&A, Help & Troubleshooting] anyadike:
I stuck mine in my laptop & used Windows recovery software
[Galaxy Note II Q&A, Help & Troubleshooting] rickafterburner:
Amazon replaced SD card and problem cleared

I don't understand, but I started by trying to contact SanDisk via Amazon to see if they'd gotten other complaints; Amazon sent me a new card and the problem cleared and didn't return.

I wonder if it's some issue between the new firmware and some SD cards. In any case, it's been a few weeks, and the symptoms haven't returned.

Good luck all, and thanks for the thread.

I have also started facing this problem recently. Bought a new Sandisk 32GB ultra class 10 card. But this started after I did an auto root. But from what I hear that is not the problem. From what I have read in this thread it looks like I will have to get a replacement.
[Galaxy Note II Q&A, Help & Troubleshooting] stilljk:
This happened to me just now. My Note 2 keeps unmounting my sd card and says it's safe to remove. I haven't rooted it or anything. I tried rebooting, taking the battery out, removing the sd card and putting it back in, qnd nothing seems to fix it.It's running on 4.1.2. This is a total bummer as I now have no music for my commute to school.
[Galaxy Note II Q&A, Help & Troubleshooting] alfa7d:
Same problem with same sd card( sandisk) . It happened to me after i unrooted and install CMW recovery to my phone. Then i return my phone back to stock 4.1.1 and update to 4.1.2 but still facing same issue !!

maybe we need someone from sandisk company to see this thread and how many people having this problem with this baaad card !!

[Galaxy Note II Q&A, Help & Troubleshooting] arctic84:
So.. i figured something out..

so now I have two sd cards

32gb samsung microsd

64gb samsung microsd

The 32gb started having this issue when I put the phone down lightly (and i have a tpu case) and it would just give me the unmount notification. Even when I went jogging and it was in my armband.. same problem.

Since then I purchased the 64gb samsung microsd (would've gone with sandisk, but heard about too many issues) and have yet to see any problems with it *fingers crossed* (btw i'm rooted and running tweaked)

My girl and my friend both have the note 2 but are using 16gb and 8gb microsd cards and have yet to run into this issue.

So, that this point i'm not quite sure what to blame.. the 32gb sdcard.. which had NO issues whatsoever with every other phone i've had..

...or the galaxy note 2? O_o
[Galaxy Note II Q&A, Help & Troubleshooting] 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 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.
[Galaxy Note II Q&A, Help & Troubleshooting] jitin02:
Planinng to get a new one as mine 32gig is also givin same issue.

Should I go with transcend/Samsung or any other. And 32/64 if it really matters for this issue
[Galaxy Note II Q&A, Help & Troubleshooting] rascal123:
Why don't u claim for your warranty. .? Mine after replace with new one under warranty the problem have gone like forever...:D
[Galaxy Note II Q&A, Help & Troubleshooting] 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, so don't bother with it.
[Galaxy Note II Q&A, Help & Troubleshooting] dukemol:
got this problem

stock rom, rooted. Sandisk 32Gb class10.

my sdcard is randomly unmounting, deepsleep or not. even if im using the phone, the message appears.

having this message for mouth now (got maybe thousand of this notification), same sdcard, using it every day and still no data loss, corrupted or any issue.
[Galaxy Note II Q&A, Help & Troubleshooting] Crescendo Xenomorph:
the data loss is mainly at MP3 files and text files...

and some deleted data will remain there but unopenable, can be observed if you plug the SDcard in computer/lappy...

trust me, better get the extreme pro 16gb one than this ****ty ultra version, its not worth your data...
[Galaxy Note II Q&A, Help & Troubleshooting] luismedina:
I switched to an ADATA 16 GB class 4 card and the issue is gone, it's been around 48 hours since I swapped the card and it is working normally, the card monitoring app shows no unmounts in this given time period. It's totally SanDisk fault.

hey guys this is important:

I had this problem...I had a sandisk uhs c10 in my note 2...a while after it began to give me the sd card removed unexpectedly warning with a huge battery drain so I removed it thinking I can sell it to someone and get another card.....that was around mid january

on several occasions I tried to give it another shot but with no luck. that until yesterday. .I was upgrading my kernel to wanam's latest adam so I thought I give the card another shot.i formated it in my phone and its been 36 hours now without a single warning. . and media scanner is back to normal 1%

I really think you should give adam's kernel a shot

Ya, no problem for now...

We've heard many stories about how so-and-so did this or that to 'fix' it, only to hear back from them a week or a month or 6 months later, stating that the problem resurfaced for them.

I really do, genuinely hope it is gone for you, because this thing sucks. I'm just suggesting to be prepared, in case it's not really gone.

Thanks for the tip. Perhaps this is something that Google can add to the mix when they finally get around to tracking down the root cause of this issue...

This is definitelly SanDisk's fault. Just read this whole thread and you'll realize that everyone experiencing this issue is using a Sandisk card, and the problem is gone after replaced for another brand.

I'm having this same issue for the past few weeks... Mine is a Sandisk 32gb Class 4, and it's 5+ months old.

The only thing I did since I bought the card was flashing a kernel (Speedmod), but the card worked fine for some time after that.

I'm looking forward to buy another brand. After this thread I'm pretty sure that I don't want to mess with Sandisk anymore.

I have been in contact with SanDisk India team thru emails and today they have replied stating that they have 2 Replacement Centers in Mumbai. 1 in Andheri East & 1 in Grant Road East. I am waiting for the complete addresses so that I can visit them ASAP and get my SanDisk Ultra Class 10 (32 GB) MicroSD card replaced. By the way, I am facing this "SD Card Unexpectedly Removed" error since past 3 months and really getting annoyed as every time I have to Reboot my Android Phone (Karbonn S5 Titanium) and the problem gets solved for few hours.

You should go to Samsung to check whether the problem lies in the hardware or software. If it is a software issue, Samsung will repair your phone. If not, they will probably ask you to go to Transcend to get your micro SD card replaced.

no phone but card problem

Same problem with me, so i think it is safe to assume that this is not a phone, kernel problem but card itself.

Frankly i was relived to read this thread, as i was thinking my phone went kaput. It would drain battery up untill it has no juice left to power it anymore.

Using same 32GB Sandisk ultra (purchased in 10/2012) with HTC Wildfire S.

So relived i had Dropbox sync on which saved my photos else i would have lost every memory i had .... :angel:

I'm having the exact problem here since last week after I've been using the Sandisk Micro SD Class 4 for over 5 months now.

Much relieved after reading this thread as I really thought it was a problem with my phone.
[Galaxy Note II Q&A, Help & Troubleshooting] mechexpert:
Ditto problem

I have been using SanDisk 32GB (red/grey) class 10 ultra card since oct/2012 with my HTC Wildfire S. Untill a few days ago, my fone would be full charged at night & would die off completely (to extent that it won't even turn on, only red light flashing). I thought my phone died, changed rom, changed kernel, nothing worked.

I was using INT2EXT script for second partition to increase internal memory. I lost all hope up until a random google search lead me here. Then i changed my card to 2gb(only one lying around) & the problem vanished. So it was confirmed it was the card's fault.

Then came the SanDisk RMA process, after wasting about 30-40 minutes on that stupid automated call i finally was able to raise a ticket & i was told i will be transferred to next deptt who will tell me about replacement, but call never was forwarded & i was disconnected.

Next i got an email, stating there is no stock availability & it will take about 4 weeks to arrange a card for me. :(:confused:

I felt furious & started cursing on the facebook page of sandisk & then twitter, & then i got a message to share my contact details, did that, got a call from some representative & after listening to my case, he said he will arrange the card in a week. i said ok i am fine with a week but not 4 !!! So in about 4days i got the replacement, it working fine for now, don't know how long its going to last.

So if anyone reading this has faced similar problem, just call for RMA, & get the card replaced, your phone is not at fault !!!!

Good day !!

Hey

A friend of mine broked accidentaly the screen of his s3. Since then the screen is black and won't work. Everything else is working fine. The problem is that he hasn't rooted his phone and haven't enabled usb debugging. He also have a pin so the method with kies won't work either.

Whats the easiest way to save his data?

Flash a rom and root it and then via \push over adb? Or is there any other way?

Thanks for your suggestions :)

i haven't tried it out but might work

If you had usb debugging enabled you could emulate it onto pc but you will have to have it set up before hand.

Or is it possible to get the device info without screen?
