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?

Mines doing the same thing.
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!

i had this very VERY strange thing happen. On my universal i upgraded it to WM6.1. I was very nervous about bricking my phone at first, but everything went well, and i used my phone for about 6 months. Then all of a sudden, i'm walking down the street one day, and i get a phone call, and my phone decides to turn on the "Low Battery alarm" at the same time i pickup the call...
My phone completely freezes, and so i reboot my phone, and i get this "No SIM card" error. Which, i know there is a SIM card in there, because i didn't take it out, and it was working just fine only 30 seconds prior.
So, i went home, swapped out the SIM card to one of my old SIM cards (a number from a previous city) and viola! No SIM Card error.
Something happened to my phone at that moment in time and just like FRIED my SIM card. So, easy solution, i just go and get a replacement SIM card. Ok , DONE.
....Happy pimpin with my HTC Univeral, right?... WRONG....
At the same time this happened, my SD card slot just seemed to STOP working. Which is really weird. I even tried enabling some system background processes and whatnot, ...basiclly turning EVERY process on. But that still had no effect.
And i can do almost nothing useful with this device now except for make phone calls and do SMS. Having a large brick in my pocket just for phone calls is a bit of an overkill i think.
So , any suggestions? How do i get my SD card working again.
BTW, i'm in china, and every repair shop that i went to REFUSES to touch any HTC phone. There seems to be a massive education gap. But if i had a nokia phone it would be no problem for them....
*sigh* STUPID CHINKS!
*grunts*
any thoughts on how to solve this problem with the SD Card?

Hi welcome to forum and well you can try to flash another rom and see if it works or not.. if it doesn't then might be hardware problem...
i'm downloading the original WM5 ROM now, and will try to reflash it tonight. I really never needed WM6, except for when i was at university (here in china), they had a problem with the CAT5 cabling, and had to redo all of it. And so the entire dorm was out of internet for 1 month. So i used my phone as a WiFi router to share my 3G data connection with my notebook. For some reason, the software would only work properly with WM6... *sigh*....
now i have a 3G Net card for my notebook....hehe
^_^
Details please?
Which ROM?
What SD card?Make?Capacity?
How is battery working?
Did you try ANY other cards?
Did you try formatting it?
Because SD cards getting corrupt is a very comman thing.
I did lost three 4GB SD cards last year and one 8GB SDHC. ( all made in China )
So I know how it feels.
Damaged SIM...it never happened to me.
As a rule in china... NEVER under any circumstances buy anything without a warrenty. HAHA. I've been here for like 4 years. But with that aside...
i can put the same SD card in my computer, and it reads just fine.
I have even changed from formatting it as FAT32 to FAT16, and still it doesn't register.
I have had the same problems with the 4GB cards too. Unless they're really high quality, they're kinda crappy and prone to defect. However, the card(s) that i have are low capacity. 512 MB, and 2 GB. So there wouldn't be any issues with the capacity of them being too large.
Ok, this sucks....when i try to reflash my phone back to WM5,.....it says i have the wrong image ERROR code 100 i think it is.
But i downloaded the Factory image from this forum for WM5.
I have WM6.1 on it now, so....how do i downgrade? Just reflash?
BTW, this is an English Language Version. So that shouldn't be too conflicting.

have a look on the Wiki
Perhaps using the MTTY app can help you
Good luck,
i found the reason why it failed....that rom is not ENGLISH
my SD card dissapered on my UNI when my battery got old. it seems it just didnt have enough power. I put an old SD card in and that works but i got a new battery within a week.
whenever my universal didn't have enough power for the SD card , it would sound the low battery alarm, and then tell me it didn't have enough power for the SD card.
I would think that if i can still run wifi for 40 minutes or so (on a full charge), there should be enough amps in the battery to turn on the SD card....at least...one would think *grin*
Ok, well, i somehow managed to get my phone flashed to WM5......using the German WM5 ROM mind you
It's actually not in german, everything is in english. Anyways, whenever i put an SD card in, it still doesn't show up.
The IO conctroller used in Uni usually never die.
I would suggest you to unmount the device, use a hot air gun on the SD socket connector and nearest different points.
regards
So last night for the second time i get a red triangle notification that tells me my SDcard was unmounted unexpectedly, basically it thought i removed it but obviously i didn't since u can't even reach it with the battery in. I'm assuming its a hardware defect. In order to fix it i have to remove the SD card and reinsert it.
Anybody else have this problem?
Sent from my ADR6400L
Thats a HW defect, if you are rooted, unroot and take it back. They will give you a brand new device.
That's what I'm going to do, only problem is i bent the kickstand and left tool marks when i fixed it
Sent from my ADR6400L
What is the HW defect? This problem of having my sd card unmounting unexpectedly happend only twice, does doing a FAT32 format help? When this would happen to you, was it happening all the time? Thanks, any info will help
Hi all,
Having the same **** here, SDcard was unmounted unexpectedly....
OK.... trying to tell what happened:
I have the phone since Jan 2011 (HTC DHD) I bricked my digitizer and 2 weeks ago I was brave enough to open it to try to replace the digitizer, but gave it up as the display/Digitizer unit was glued....
However, after I put the DHD together again Problems with SD-Card...
By now - I ruled out for myself that it is not software related, as I Wiped the phone fully (formated /data , /system , /cache and so on) and installed a rom, I never had this problem before with - but now I have...
Also I tested with other SD-Card and having the same problem (SD Card Kingston 2 GB and Sandisk Class4 23GB)
So as Said I can rule out the Software and the SDCard itself....
I'll disassemble the phone again to see if there is maybe a loose connector...
If you don't hear from me again this solved my problem
Kind Regards,
Der Matte
OK.... I am Happy to say that I belive that I fixed my issue.....
as stated before, I opened the device and put it together and then I got the error as described above....
Now I just took a few tools and opened it again....
2 things I found wich were not 100%
1: connector to the mainboard was bended a tiny bit but looked correctly seated anyway...
2: very close to the SD-Card reader unit (the slot where you push in the card...) there is a bit of tape... half of it is isolated - half of it is not esolated to get the ground connected to the frame....
I placed the sticker 180 degrees... so the isolated part was not at the right place...
I corrected this - so far all is working again....
So I presume... as I had a Hardware issue in the phone (fair enough caused by myself) all the people having the same symptomps are having a HW problem as well.....
So Now I am optimistic, to get my digitizer replaced too - but this time I will get better tools first
Hope this helps all the other people having these symptoms
If the error comes back, I will update this....
My device HTC DHD
Der Matte...
Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the “Media” scanning process and significantly draining the battery.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:
https://play.google.com/store/apps/details?id=com.sdcardmonitor
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?
So I can't figure out the cause of this but here are the facts and the dilema.
The issue - Phone gets really hot, battery drastically drops (I mean from 75% to 25% in under 10 mins), cannot read the SD card, if I try to wipe cache and davlik cache and reboot the phone automatically reboots into recovery. Thankfully after pulling sd card, sim card, and battery I was able to get the phone to boot up properly again, but today the issue started again. I haven't wiped dalvik or cache today because the phone won't read the sd card.
My thories on causes: (1)phone was sitting my my sink in the morning and some water leaked to where the phone was sitting, the sticker is now pinkish-white, but the phone was never submerged in water it was a mere puddle, (2) I purchased a new sd card, could be a bunk card causing issues, (3) I am running Weapons but haven't seen anyone else with this issue. I haven't downloaded any new apps.
Any thoughts?
Let's see...
1. So was it OK before you put it in the sink this morning?
2. Does it run OK without the new SD card?
A. I didn't put it in the sink - water sprayed from the faucet to the area of the phone. It really did not get that wet, and as I stated the sticker is mostly white with some pink on it.
B. Update - I took the sd card out and no more overheating or battery issues. WTF? I am going to put the old 8 gb card in when I get home. I bought a 16 gb class 4 SanDisk on Amazon.
Has anyone else had this issue?
try a different kernel, or a different rom all together (while testing different kernels)
expect to flash it many many times and playing around with apps and titanium backup (or your favourite app manager/uninstaller/backuper) before you get DAT setup
i say kernel specifically because maybe it's not using the sd card efficiently
more likely i would think though is that maybe you had a bad app(le) killing the phone that happened to be installed on said sd card

LOL! LG made him do it!
Sorry OP, but that was funny.
Update, went back to old SD card and there are no issues. Contacted seller of SD card and got a full refund after sending links to several other sites reporting the same issue.
As I stated the wate exposure was minimal - my blackberry's sticker turned pink when I had the phone in my pocket in a rainstorm - but thanks for the childish comments - you guys are real winners.
