On the average once a day my phone "loses" the SD card. Things will be working fine, but then suddenly it won't be able to find the apps I've got installed to my ext2 partition, nor will it be able to see the fat32 partition.
When it happens, I've got to shut the phone down, take out and reseat the card.
I've swapped out my sd card and tried another one and it's exhibiting the same behavior, so I don't think that's the issue. Seems to have started happening around the time I installed the JF 1.43 update.
Anybody else having this issue? Or could it be that my phone's just starting to go bad?
sounds like hardware to me :-/
hopefully someone has a tip you can try

That's what it sounds like to me. It's annoying but usable at this point. If it gets worse, though, I guess I'll have to send it back and get a refurb unit.
I had the same problem with the sdcard the phone came with but it went away after upgrading it.
I had this problem too and what I've found may sound really stupid, but keep in mind it's an observation, not a statement of fact...
It seems that the SD card is REALLY sensative to temperature. I live in Vancouver and over the the winter, we've had anything from below zero to above, I've noticed that whenever the phone was in the cold, the SD card would never stay mounted, but recently in the warm weather, the I haven't had a single problem with it becoming "lost" sounds stupid, but it could be your problem to if you live in a colder climate. Mind you it still gets lost, but a simple reseat of the SD card normally fixes this for me.
Meeker
I've had a similar issue wasnt sure what was causing it. The I noticed that I fiddle with the sdcard door. After doing that the card wouldnt show up anymore so i think I dislodged it slightly. Never know could be the issue.
Just got the phone 2 days ago, downloaded a number of apps from Android Market, moved the ones to SD cards that I could, but after a while, a lot of them fail to start with the error " has stopped unpectedly" when I try to launch. Used same apps on my 3G slide without issues. Have done charging of the phone during that time... And I'm using the same SD card I used in the 3G, so don't thinki its the card..
Any ideas out there. An issue with the phone??
I cleared the problem by remounting the SD card via the settings command. So still a question of is there an issue with the phone losing the SD mount or possible I need to try another SD card. If it continues, I will try another card...
I've had my sdcard randomly unmount on me a couple of times.. It's happened on both my first and second MT4GS, but it's very infrequent.
Doesn't seem to be ROM dependent, although i've been running stock modded my way for a little while now. I think the last time it happened to me was about 8 or 9 days ago, and it's happened 3 times since I got one in the first week of august.
I had it happen to me the first time before we had S-OFF for the phone, so it's nothing any of us did.
I wasn't worried enough about it to look into why or do something about it...though I was keeping track of how much it happened in case that changed. Now that I see i'm not alone maybe we should see what's going on and if it's something to worry about.
I've had a different memory card in each time it happened, one PNY and two SanDisk cards ( 8 and 16 gig). I don't remember what I was doing when they happened, or how long the phone had been on.
I don't mount/unmount the card manually while the phone is on, the only time I ever swap them is when no battery is in the phone. ( overkill, I know, but having seen someone pull a hard drive from a running x86 machine...I just have the methods i'm comfortable with.)
Has anyone else experienced this? If so, see about throwing some details about it here.
Thanks for the post. Its been good ince I remounted yesterday. But when I thought about it, I did remove the card with the phone powered off and put it back in beofre the problem happened yesterday. Now the apss were working after that, but stoppedworking later on then I remounted. So it could be related to the card removal/replacement. I will not remove the card anymnore aand will see if the problem occurs again..
FYI - Im using a 16GB sandisk
Depending on which apps you moved to the sdcard that could be your problem entirely. I know if i try to move system apps or widgets or something like that it'll cause it to fc every time. i try to keep as many on my phone as possible except for games and crap that aren't in any way essential to the phones functionality and i know i'm not going to need access to very frequently since putting things on the sdcard affects their speeds.
so a couple months ago when I got this phone, I bought two 16 gig micro sd cards(order mistake, and I never returned one), one Patriot and one Wintec. a a month later, after a reboot, I had a problem with one of them losing the data on it. like, all the apps installed there, plus pictures, all gradually disappeared except for a few folders that were emptied. I didnt know whether the phone or card caused it, so i switched to the other one, and put the one that had deleted data into my tablet (iconia) to see what would happen. well things went fine for a while, and then there was a point where I was taking the card in and out of the tablet and switching it between that and my computer, and the card eventually stopped working altogether. so I figured it was just a bad card.... but then the one in my phone los data like the other one originally did.
I had backups, so i formatted and reinstalled them. but over the months, it's happened again 3 times, then a fourth time today. so I'm planning to format the entire phone and card and see if it ever happens again, i.e. maybe the phone is the problem. I notice it usually happens after a reboot, i'm thinking maybe Samsung's mods have caused the media scanner to be unstable. anyone else know what's likely to be causing this?
if it helps diagnose, I'm attaching two pics of the sd card contents. it's odd, a bunch of the file and folder names have been renamed, with random letters replaced with other letter and characters. and for some reason, the whole card was renamed "ba".
in short, do you guys know if this is more likely to be a problem with both cards having been bad, or my phone corrupting them? I'm hoping it's not the phone, that would be difficult to fix i'll bet.
gah forgot to attach.
OK after reverting to factory stock, updating to the latest and rooting, I still have this problem. Doesanyone know what it is caused by?
I haven't searched but saying that I've never seen anything like this on Desire or Sensation threads before.
I went to copy something over to the phone (using Windoze Explorer) and when I looked at the contents. I saw the attached. The phone, when I use Root Explorer, and PC agree :-((
For reference I've used Linux, PC (Explorer) and ADB 100% to copy files over successfully before, so no posts about using one or not using one.
All the Filenames etc. have been completely screwed up. Looks like they've been converted to DOS 8.3 format.
I have never ever seen this before. I think I must have run something on the PC when the phone was USB connected. It's about the only thing I can think of, the phone/SD Card/ROM have been 100% reliable so far.
LUCKILY, I made a rare backup of my SD Card yesterday. I usually remember to make one once in a blue moon.
All I can think is to recommend folks to disconnect the USB drive when not needed and do Backups (of the Phone and also the SD Card).
Anyone seen this before ??
sorry to say this to you but your memory card has gone corrupted.
i know this because this has happened to me alot of times.
this happens if you use unbranded memory cards but this also happens to branded memory card.
the only solution i can give to you is buy a new memory card. and the main reason this happen when you connect your phone to your pc/laptop and use it as diskdrive and take the wire out while transferring data.
the only way to prevent is to use a safe remove usb and than change your diskdrive to charge only and wait till everything is loaded and then disconnect your usb wire.
also if you fornat your memory card it will work but i can tell you this that this willhappen again and this could happen without connecting your phone to computer. so to only prevent data loss buy a good new memory card.

Correct me if I'm wrong but I'm 99.8% sure it still works and he doesn't have to buy a new memory card yet .. I don't know where you get the idea that his memory card is completely dead! It looks like he still has his files, there's just all that junk in there! Worse comes to worst, he has to reformat it which I think may not even be necessary
Anyway, I've had a similar situation as yours and "repairing it" fixed those issues up. I didn't even reformat it, just repaired it. Try that! (Assuming you haven't already reformatted it anyway)

Update:
Card is fine. Just the filenames/pathnames got screwed.
As I said luckily I had done a backup of it yesterday, only by accident. I mounted the card on the PC directly (USB adapter) and deleted / copied stuff back.
It must have been something on my PC I ran as it changed the filenames/pathnames to 8.3. I did run something (can't remember the name) as I had problems doing the copy (SD Card to PC) for the backup. A few (4 if I remember) files were too long, exceeded the 255 limit. I D/L something to see what was the issue, turned out to be some book preview I'd accidently down loaded from the market.
All good and working now....
As I said just a warning that **** on the PC can screw the SD Card on the phone.
Backups (Nandroid and SD Card) are a pain but can be life savers.

i don't mean that he should buy a new memroy card because after formating/repairing it the memroy card will work but this corruption can happen again. if this happens again the onl;y thing he can do is buy another memroy card. this has hapened to my unbranded memroy card which was 16 gb class 10 and it happened atleast 5-6 times. since i couldn't take another corruption i have ordeered class 10 32gb lexar memory card which is working fine and its hasn't gave me any problem since i've been using it
Man that's what happened to one of my other 4 gb cards I don't use anymore. It was kinda funny. I ended up reformatting it, but an odd thing has happened... 3gbs went down to 1.7gbs... I can't even access the remaining 2gbs... no matter what I've tried.
I didn't buy a new card since it works just fine. Been using it as a "mini" file storage card for 4 months and no issues yet. =D
You sure everythings fine? A lot of files on that card read "0KB" which is definitely not a good thing.
Best of luck.
Anyone with any issues with an SD card should first attempt a low level format.
I'll leave you all to Google that one.

It's fine.
Just that something I used, never used it before, to check filename/pathname lengths (due to FAT issues), seems to have converted everything to DOS 8.3 format. The ones that didn't conform to that were created after a phone re-boot.
This was only as a warning that **** does happen and backups, while a pain in the arse to do, can save a load of pain.
Off to try some ICS ROMs now so expecting a load more pain, d/l, CWM, Wipe, Swear, revert back to CM7. ;-)))) Just need to make sure that nothing updates my HBOOT..
Try .. A Full format of the SD Card
You need to do a Full format and wipe of the SD Card .. I have " fixed" a few this way.

Hi everyone,
I just wanted to let you know about what I have found out.
A couple days ago my I9505 started to overheat a lot, although it was not used and in my pocket. At first I thought it was the battery, so I switched it off and took the battery pack out, but it turns out it wasn't hot... but the phone was! Especially the upper part (around the camera, and even on the screen side). I waited and restarted the phone. After a while it did it again and my phone rebooted by itself after a few hours, which was a complete surprise: I have been running the last stable version of SlimBean, which is awesome and really stable for the past couple of months (the reason why although I have tried some KK based rom I ended up going back to 4.3).
Anyway, I though maybe something was wrong with my settings and I decided I would test a few KitKat ROMs, and so I did:
- SlimKat
- OmniRom
- CarbonRom
- AOKP
- CM11
- and a few more...
With all of them, I experienced the same issue. And I had them all for a few hours, because I know at the beginning the phone always retrieves data and apps from google servers, so I figured it was bound to heat, but not that much! And the random reboots happened in all of them.
This morning, I was ready to flash back to a stock ROM to have the phone serviced (I have knox tripped but I don't care, I don't think they would mess around with me about it here in Europe, at least from what I've heard, and anyway, I'd just tell them that Kies did it ), when I realised that Hey! the day before it started, I was unable to copy/paste all the data from my 32GB microSD card to my computer using the USB cable. I would systematically get an error saying that the device has been disconnected from the computer. I had even wondered if my USB cable was damaged, but seeing that the phone charged alright, I did not pay too much attention to it.
I started to investigate the card and retested some ROMs I had tested previously. This time I would not connect, but I did try with and without the card, and BINGO! every time I put the card in, it would overheat.
I then tested my card with an adapter in my computer, and there seemed to be something wrong with it, because even then the copy operation would hang! So I formatted the card (after I had backed up everything I could), and put it into the phone, where I formatted it again with the phone. Now the card has been (albeit empty) for a few hours in the phone, and no overheating or random reboot in sight (running the latest stable SlimKat).
So if your phone starts to overheat, especially the upper part, check what happens when you remove the SD card.
Hope I'll have helped someone with this. If you don't hear more about me in this thread, it means everything's alright. I'll start re-loading things on the same microSD card. I'll see if it is still faulty or if the phone heats up. If it does, I'll try with another microSD and see if it does the same.
Cheers!

Do tell me if the micro sd card is the problem. I have this overheating issue since a year and haven't been able to sove it. Yet. But i remember trying to rovercome this issue by the micro sd csrd method, it hadn't worked..
Anyways, this issue with s4 is too common, i know 10-15 people with the same issue, so i think its a hardware fault..

Thanks for this, very useful advice. Just recently I was having some issues with my phone not writing to my SD card and the card inexplicably filling up with data. It turned out to be corrupted data in the Android folder, so I backed up my stuff, formatted the card etc and that fixed it (as well as freeing up about 6gb of space on the card)
After reading your post it occurred to me that corrupted data may have been causing overheating in your phone, due to the card constantly being read over and over.
I didn't experience any overheating myself but it could well be the same cause. Either way, definitely worth checking if you're having overheating issues.
Very interesting. I for one reformat my SDcard every 2 to 3 months. Just a simple maintenance that i like to do. This is something good to keep in mind and thank you for sharing mate.

So! Some more info on this (just in case someone's interested), but first FYI Armaan.ag, the card seemed to be the issue.
I had another microSD card of the same capacity, so I copied every single file that was on the faulty card to my computer, and I noticed there were two mp3 files that were in fact not really mp3 files, but rather some junk that the phone must have created at some point.
I deleted these two files and copied all the rest to the new card, and it works just fine. So at least it's not a hardware issue on the phone: it reads the card content fine and does not overheat (well, IMHO a phone should not overheat when it encounters a corrupted file, but that's another issue)
As for the first (faulty) card, I have formatted it (full format) and checked it for errors. Windows tells me it is fine. I'm now copying all files back to it, I'll test it when it's ready. If it still crashes my phone, then I'll try on my wife's phone (I9300) and see what it does before I return it for exchange (the card is not even 3 months old).
Cheers!

When the OS is indexing files on the sd card the CPU will be working, if there is corrupted data on the card, it can interfere with the data indexing and cause the OS to read the card over and over. This will keep the CPU active for longer than it needs to be, and when the CPU is active for extended periods of time it can cause overheating.
Alternatively, the overheating could have been caused by a physical fault with the sd card reader or the sd card itself. Either way let us know how you get on.

Thanks for this!
Getting an S4 this week so will keep the page bookmarked should I have any of the issues mentioned here. Thanks.
Google plus heated my s4, check settings and unchecked other folders.
Maybe upload on WiFi only. And when charging?

Everything fine now
Just thought I'd let you know after re-formatting the card:
Complete format with windows, then erase card on the SGS4, which then complained that my card must be formatted, so I formatted it with the phone.
I've been going with the original "faulty" card for more than a week now, and I have had no overheating issue. All the files (except the corrupted files) that were on the card when the problem occurred are back on it. And no issue.
Hope this helps!
Cheers!

1.this is a 7.9mm phone
2.the back cover is thin as a sheet of paper
3.the sdSlot has been installed behind the processor (for speed reasons) and it's made of metal components so there s heat transmission
just replace your cover with the stock one of the 9505 black edition and tell me ..anyway i wanna try this solution tnx in advance

You're not wrong at all, but the fact here is that there was a real problem: it was really hot AND there was a huge drain on the battery, which changing the back cover wouldn't have solved.
Besides, I no longer need to do anything, since after formatting the card, it's back to normal, i.e. no overheating. But you're right that heat reaches the surface of the back cover when e.g. downloading or watching streamed videos for some time.
Cheers!

The i9500 overheats too, so I'll cehck if the SD Card is the problem next time it happens. Thanks!
