problem with apps stop working

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.

GS3 destroying SD cards?

My shiny new Galaxy S III has now destroyed two 32gig micro SD cards on me. About two weeks after I installed the first card, my phone started giving messages about the SD card being improperly removed, then it would immediately try to re-mount it, then would say it was removed again, then finally started just repeating the "unable to mount SD card" error until I physically removed the card. I argued with best buy to give me another one, and now today (about two weeks after installing the new one), the same thing happened. I put the card into a USB reader to try it on my computer, and now even my PC does not recognize the card.
Has this happened to anyone else? What can I do to fix this?! I pre-ordered the phone from verizon, so I'm now well out of warranty replacement time.

I have a 32gb MicroSD card and haven't had a problem. I do wish I could use it more as internal memory rather than hardly usable external storage...but that's a different issue.
Sorry I couldn't help, but just wanted to say that Galaxy S III does support that much external storage. Maybe a hardware issue? Try troubleshooting it with another MicroSD card.

Gotta be the cards you're getting I would think. I had a 16gb card that came with my Droid x almost 3 years ago in it for almost 2 months before the card finally crashed.(I'd abused that card tho, carried it in my jeans pocket, left it sitting on my table etc) Then I put my 64gb in it. It's been a little over two weeks now and no probs with it. I've written too it and erased and so on so I've actually used it. It's almost full now actually lol.

I have that same 16 GB from the droid x. Do I still need to format it if I flash a ROM? And how do I check what format its in

My 32gb card was doing that on stock until I finally installed a custom rom. No problem since.
Synergized GS3

SD card gs3 issue
I also had trouble with my external 16gb card after flashing 2 ROMs (synergy & beans v9). I was not even able to get a computer to recognize the sd card after the flashing.
I thought it had to do with using a stock, then rooted stock, then custom kernel. i thought the combination and repeated TBU access over a 4 day period just trashed it. maybe there is more to the story?

1) What is your ROM flashing history (what roms, how long were each installed)?
2) Which rom did you notice the problem on?
3) Were the original and replacement cards the same make/model?
4) What format were the cards in (FAT32, exFAT, or other)?
5) are/have you overclocked your cpu?

Thanks for the responses guys. I'm still fully stock, I haven't done anything to the phone (yet). I don't know what the format was, I just put them straight into my phone and let it do whatever it wanted to do. The original and replacement are the same make and model, from the same store. So before i panicked too much, I was considering buying a new/different card from amazon and seeing if it does the same thing still.
Just didn't know if anyone else was experiencing this, or had any thoughts on why that would randomly happen on a completely stock phone?

That sounds like your best bet. There are plenty of crappy cards out there. My ADATA 8GB class 10 has been great so far. I have noticed that the GS3 gets really hot right near the cards (micro sd and sim). Can't be great for the cards long term.
I've had my VZW GS3 since 7/5 and have been fine with my card. I've seen plenty of people who've had trouble with FAT32 vs exFAT, but none who have lost their card.
I have seen a ROM break cards before (an early AOSP gingerbread build for the Fascinate claimed one of mine), so I've actually been looking. This is the first thread I've seen.

I've also noticed it gets really hot toward the bottom of the phone. Now that I think of it, both times I noticed the SD card issue right after taking the phone out of my pocket. Maybe it's just getting too hot? I wonder if my case is also holding in a lot of the heat and making it worse? I wish there was a way I could test things without breaking an SD card every time!

My GS3 fried a new 32gb card that I put in it after about 3 weeks. Randomly got an "unreadable SD card error", can't correlate with any specific activity. I reformatted the SD card & it works again in the phone. I was rooted, running stock at the time. Maybe it's the heat, but I don't recall it being hot at the time (I also don't recall it not being hot...)

Try sandisk.I was having problems with lesser brand
Sent from my SGH-T999 using Tapatalk 2

I have been using the 32 GB San Disk brand card that came with my thunderbolt and it's been working great.
I really don't know what could cause that to happen to a card and I haven't noticed any other reports of it happening with this phone.
If it comes down to it VZW SHOULD give you a replacement because it could be something to do with the card slot in the phone. I would try talking to them if you can't get it worked out.

So going on the theory that maybe it's just getting too hot, I just ordered a 16gig sandisk ultra micro SD card. It claims to be "temperature proof", whatever that means. Hopefully that clears things up, otherwise I'll have to deal with Verizon, and I'll be super mad if they give me a refurbished phone when this issue actually started two weeks after I got the phone.
If I don't post back here then you can assume all has gone well!

16gb card from droid x
same as others, used the same 16gb card from my droid x, transferred to the bionic when it was released, and now have been using it in the GIII since release. no issues.

I don't believe the phones are getting too hot to do the damage. The hottest temp my battery has gotten had been 106 and they say that heat damage isn't even a concern until around 140 or so. I would think the cards could take the same if not more than the batteries.

I had a similar problem, my sd card wasn't destroyed, but it would randomly become unmounted. It started happening after I hooked my phone up to my corporate email and it forced me to encrypt my device. After I removed the corporate account it stopped happening. This was all on stock TouchWiz from the factory.

I have had my 64gb SD card for a month and so far nothing went wrong. did you buy your SD cards from a reputable source? I have always used sandisk SD cards try buying one from Sandisk or even Samsung. if you bought your card from ebay make sure the card works, I have heard that some times people sell damaged cards for very cheap. But other than that good luck.

16 GB class 10 sandisk 30 mb/s version died on me with this phone after 2 weeks, stock ROM, formatted with phone. It was brand new.
The error I had was it became read only. And no it was not fixable, I tried everything. Low level format, checking permissions, different OS's, putting it in SD adapter and messing with lock switch on there.
I read class 10s are more prone to die quicker and aren't necessarily better, but just different from a lower class. Ie a lower class will last longer because it read and writes differently and doesn't skip certain safeties like a class 10 does.
Running a class 4 16gb sandisk now and it is annoyingly slow.

I9505 overheating? Check this, you never know...

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.

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!

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!

Recurring SD Card Notification

I have been using my phone since last night and after my last reboot I have a recurring 'SD Card For transferring photos and media' notification. It lets me dismiss it then re-appears after a few minutes. If i click on it it opens up 'My Files' but there are no messages or options regarding the notification. Long pressing the notification loads up 'System UI' App notifications but again nothing that helps remove the notification. Anyone else have this problem? I have looked through every settings page, My Files options, google etc but I have found no solution.

That happened to me too but I don't think there is a fix sorry ?

+1... It's a bummer!

Keeps happening to me too

Tried formatting but that didn't help. Ejecting and re-mounting seems to fix the issue for a few minutes.

I smell a fast patch incoming lol. Especially since there wasn't a zero day patch.

I only get the sd-card notification after power the phone on. Never comes back unless I shut phone off and reboot. I was having very slow to wake phone issues while I used a new Samsung 128gb class 10 sd-card. I changed UT to a 64gb SanDisk sd-card, class 10 U3. No more issues.

Only happens to me when reboot phone.

same here, only when i reboot my phone, regular s7

Something on my phone is dismounting the sdcard (says something about unexpectedly dismounting for a few seconds) and the message pops back up when it re-mounts. I don't think its a bad card because I just got it last month and used it with my S4 for weeks without any issues. Going to try re-seating the card.

You're not alone so it might just be picky about the cards it uses or maybe this first batch has bad slots... Which would suck. You could try folding a small piece of paper or construction paper and taping it to the top of the card to make it thicker and press against the contacts better. It may just be a thinner card. Make sure the paper is securely taped so it doesn't come off in the phone.

Sounds like the same issue some people had with the S2 back when I had it. It was very picky with which SD cards it would allow without this problem. I will also try connecting it to my pc in a card reader and running disk check when I get home.

Really curious if a Samsung card would do this...Anyone using one?

I haven't tried a Samsung card but finally gave up and ordered a Sandisk Ultra 128gb. Will try it tonight and report back. The message for the sd card should always appear on boot since the card is re-mounted but it shouldn't appear after that until the next reboot. Previously had a PNY Turbo 64gb U3 card which was dismounting frequently. If someone could report back on Samsung cards that would be great!

Add me to the troubled SD card.

I'm using Sandisk 128GB Class 10. It did the mounted notification for the first little bit it was in the phone. I actually had previous data on mine from my G4....photos, etc.
It didn't go away when I swiped it, so I tapped on the notification and explored the SD Card for a few mins just to see what I had on there (had forgotten), and next thing I know, the notification had gone away. Hasn't come back since...

Same to me also. I use S7 reformat and I get it. When I do a cold boot I get it.

Looks like replacing the PNY Turbo 64GB U3 card with a Sandisk Ultra 128GB U1 card has resolved the issue. Only get the message at boot and that is normal. It is likely that the phone is just picky with SD card manufacturers/chips.

Galaxy S7 has corrupted my SD card

I have had my S7 since pretty much the beginning, I was fortunate enough to receive mine fairly early compared to others. Along with purchasing my new phone, I got a Samsung 64GB EVO Class 10 SD card to take advantage of the expandable storage. Everything had been going find until earlier today. I noticed that I got a notification that my SD card was corrupt, I didn't think it was that big of a deal as I didn't have very much data on the card as of yet so I clicked the option to format it. The phone seemed to be having issues reading the actual card as it couldn't seem to format it, an error kept popping up saying that the command had failed. I then put the SD card into my laptop to see if I'd have any more luck with it, and sure enough windows told me that the only way the card could be read was if it was formatted. After formatting the card through my computer, I put it back into my phone. It worked for about 5 minutes or so before telling me it was corrupt again, I'm not exactly sure where to go from here.

I had this Samsung 64GB EVO Class 10 Micro SDXC Memory Card with Adapter (MB-MP64DA/AM) from amazon with my S4 with no problems since it went on sale back in December. Last Friday I got the same message that it was now corrupt and I need to format it. My computer cant see it and I have some intense data recovery software that cant help either. Since those little SD cards have a 10 year warranty I got on the phone to Samsung. I spoke with a Samsung Galaxy expert and they advised me to call their Micro SD support team at 1-800-726-7864. I'll call them tomorrow and report back what they say.

Prolly got a fake from amazon

Amazon do insist they don't sell fake cards, however I have had the exact same problem with the exact same memory card, also bought off amazon. I've used this card in a few different phones with no issue, however upon installing it in my GS7, within a few days I got the same error message as described here. I have contacted Amazon and have had a replacement card (same one) and will see how it goes. I'm on about day three so far with no apparent issues. Tick Tock Tick Tock.....

I'll probably call them up also.. but I think I'll see what happens with yours before I just destroy another SD card

Just got off the phone with Samsung. They're sending me a RMA form to fill out through my email for a replacement. After the whole amazon fake SD card fiasco they're going through they are being very helpful so far. If you can return to amazon it will probably be quicker but I am at day 100 or so with this card.

I think I have the same problem. I have a Samsung card also (not evo) and have used it in several phones without a problem until now. In my case the card corrupts at reboot. I managed to f around and somehow the card was readable again (after re-inserting several times). However on the latest reboot I the phone no longer detects the card at all.
I doubt I have a fake card as I have been using it for over a year now and almost filled the capacity (64GB). I even formatted it when I first inserted into the GS7.
I have since ordered a new card but I hope this phone is not going to be killing cards!

RMA received. Samsung wanted a jpg or pdf of sales receipt and a pic of the back of the card. Card will be mailed to Samsung at my expense ($2 ish) and a new unit will be sent out. Fingers are crossed that the fast charge tech isn't sending card killing voltage spikes through the phone.

Just a quick update guys, in case it helps anyone, but my new card replaced from Amazon is working OK so far without issue.

Update, whilst it hasn't killed my SD card, I've just had an update and after that it refuses to write to any memory card I have. So I'm returning it tomorrow, it will read OK, but not write to.

I'm using a samsung pro+ 64GB card with my S7 and that annoying SD card notification keeps popping out. Sometimes I could see another notification said SD card removed/unmounted unexpectedly then the annoying notification. I've tried using an old 32GB TF card and I've never seen this annoying notification.
My guess is that S7/S7E have some compatibility issue with even Samsung's own newer and faster SD cards.
I'm waiting anxiously for an OTA hoping this is a software issue. I hope my S7 won't corrupt my SD card.

Update: Just received my replacement micro XD from Samsung in less than 2 weeks, very cool. I like their new usb card reader, very slick. Well see how long this lasts. I also just had a OTA update to the S7. Lets see what they fixed.

Same issue
Exactly same scenario as bensto23 first described, same SD card, however....I replaced that 64GB Samsung EVO with a Patriot 128GB and after about 2 weeks the same message popped up. But when I put this card in my laptop it couldn't see a problem (the Samsung was unreadable). So the Patriot went back in and everything was good until about a week later....same thing. S7 says the card is corrupted but it's not and works fine after removing and replacing. Haven't had time to call Samsung support but obviously this looks like an ongoing issue. So frustrating since this phone has been so flawless otherwise.

My S7 is in for repair as I type this. It's 6 weeks old. I had a 64GB SD card that I had used in my S5 for 18 months with no issues. I didn't have an S6 due to lack of SD slot and not waterproof. At 3 weeks old, the 64GB card developed a problem. I removed it from my S7, put it in my laptop, only to find it was corrupted, and I couldn't do anything with it. I put it down to being one of those things, and bought a 128GB SD. 3 weeks in again, and exactly the same fault! It is a hardware issue with the S7. I put my 32GB SD card in from my LG Leon, and the S7 wouldn't read that either. Be interesting to see what Samsung will do about replacing cards that have been destroyed by a phone!

Think i might be facing the same problem. When i put in a Sd card my phone freezes up a couple of times a day and without a sd card it running fine. I even think it messed up my first sd card because even after a format i cant write files bigger then 1 gb onto the card without getting a error on the computer. Also i can only do a quick format and if i do a full/long one it will eject the drive and fails every time. Im to scared to try a new sd card and think ill send this one back for warranty.

corrupt sd card
i have same problem with A7(2016) but i use 64GB U3 kodak SD card. it works fine until last week. i saw that i cant play musics so open memory by ES file Explorer and it says that empty. but when connect it to my loptop it had no problem and i find some files that recently created and remove files with 0 byte size. then connect memory to my phone it works nice but some day later the sd corrupts again and i repeat every thing i do last time and it work but sometime later corrupt again. i am confused how i can stop this cycle
help if can please
sorry my english language is not good

Every phone I've had, every forum for that phone, complains of issues with Samsung cards, I would never touch Samsung cards. I've never had an SD card corrupt or fail but then i've never bought a Samsung card.

Got the same problem. Every time I reboot or unmount the external sd-card, the card becomes "corrupted". When I put the card in my PC it's just fine. I can read and write to the card.
I've got the 128gb sd card from Samsung (got it for free with the purchase of the phone).
Getting sick and tired of having manually backup and restore to my SD-card when I reboot my phone. Does anyone has a solution for this?
**EDIT
This must be software related, since when I do not reboot, the SD-card works perfectly fine. It only happens when I reboot or unmount.

had the same problem in my s7, it turned out for me the culprit is when I enable the pics saving to extsd option in camera. this corrupts my extsd.
before extsd it worked perfectly fine for days and weeks and survived plenty of reboots in the S7 (and in my previous phones as well), but as soon as I enabled the pics saving from camera to extsd option in the s7, at next reboot the message about corrupted camera came out. I can replicate this problem with these exact steps, so it is 100% sw issue for me, and related to that option in camera settings... if I use my intsd for camera pics, everything works just fine, I can see and access all my other content in the extsd etc.......
