Wtf is this thread?

I got a 32gb sandisk rom off the web from some chinese exporter on ebay and ii's been great for over a year.

You probably have some problems of your own dudes....

I want to buy a 32gb card and i found a cheap Transcend TS32GUSDU1 class 10 UHS-I for 22e , so anyone had issues with Transcend 32 gb cards ?
[Galaxy S III Q&A, Help & Troubleshooting] jadeskye:
how can you tell if the card is dead? my s3 is constantly mounting and unmounting mine.
[Galaxy S III Q&A, Help & Troubleshooting] amsah:
Oh man...I just bought the S3 this summer, in August.

I bought a micro sd hc 16 GB class 10 and after 2 months (today) it died......completely, I mean, the cable cannot recognize it, neither a card reader, neither airdroid.....:(

I used the card always the same way, only for pictures and music, between yesterday and today I did nothing I can suspect to have cause this :eek:

of course I lost all my photos (backups I know I know.....)

I read almost all of the Thread and I cannot get to a conclusion...the best I think is to forget about the sdcard and try to live only with internal storage..Tomorrow I'll buy a new sdcard and the same problem will happen in a few months?! I don't want that to happen!

I know my phone was completely updated, 4.1.2, no updates were available...

People experiencing this, after all, what is the best solution?

Or what is the problem? Static electricity? Samsung hardware?

Different card brands?? (I don't think so, this problem appears to happen with many different brands)

Solution? reformat the sd card in a different "mode"? fat ex-fat?

Tomorrow I'll try to talk with Samsung, hope they can find me a solution...

Cheers

What I understand from what I read in this thread, is that your card is not dead, but is about to be, so backup all the stuff you have there.

So is there a resolution? Or what cards seem to keep working?

Ive been through a 16GB sandisk, 32GB sandisk and 64GB Samsung. The Samung card lasted a week.

Personally I've stuck with my warranty replacement Sandisk card and have had zero problems since. **touch wood**
[Galaxy S III Q&A, Help & Troubleshooting] Harv8002:
7 cards and counting

The S3 is a card killer, no question.

2 32GB Cards lasted about 2 montsh each

2 16 GB cards followed that,

After that I quit buying them, and just started using smaller cards leftover from previous phones.

A 2 GB and a 4GB crapped out after about 2 weeks each, and another 2GB that I put in for temporary storage and forgot about was dead in 4 days.

A couple of these were cheapos, but the name brand ones fared no better, the only common denominator was the SIII. I'm thinking Motorola when I come up for upgrade...
[Galaxy S III Q&A, Help & Troubleshooting] Who Am I?:
Been on the Sandisk 64GB for a couple weeks now, no issues so far.

Anyone know how to quickly update file names? I have 3 phones worth of pics/vids on the car. Some are named 2013_1001 etc, some are IMG2013 etc. QuickPic can sort fairly well but I still have hundreds of files I would like to rename so they sort by date taken only. App for that?

Samsung Galaxy S3 fried my SD

Stupid Galaxy S3, tied to get a 64 GB phone but not sold in North America, instead had to get 32 GB and any another 32 GB on SD. Stupid mistake since both got fried after about a month in. At first, I thought the cards were defected, one Kingston and the other San disk, but now I'm realizing its the bloody phone! Really sucks, since it fried it can't be read by any devices. Lost all my Vegas pics!
[Galaxy S III Q&A, Help & Troubleshooting] lefttobleed:
Bought a 32 Gb sandisk from ebay and the s3 killed it.

Bought the same from a sandisk authorized dealer (which costed much more) and its still going since a year.

How much ever they say 'original' on ebay or however original it may look, they are not. Why would they sell an original 40% lesser in cost????

But that doesnt mean s3 should kill these cards.... its like they have programmed it to kill low performing cards...

S3 does not read SD card

Yes have same problem - seems now will not read any card - cards that work fine in PC and Mac card reader.
[Galaxy S III Q&A, Help & Troubleshooting] ghostofcain:
SanDisk admitted to an issue with 32gb cards with S3, which they have since fixed. SanDisk cards also have a lifetime warranty so as long as your data is backed up your Ok.

My idea is that maybe Samsung as pushing the boundaries of what the SD specification allows and that is maybe causing the cards to fail, but the fact that Sandisk can fix it suggests the problem isn't purely Samsung's.

i'm on my 4th card now!!!

Had a mixture of kingston, sandisk and even samsung all genuine and all dead

I have managed to get all of them replaced under warranty so not as bad as it could of been but why does this phone eat cards??????
[Galaxy S III Q&A, Help & Troubleshooting] FileFixer:
Buy Transcend... I changed my genuine broken SanDisk wiith Transcend and I do not yet any problem.
[Galaxy S III Q&A, Help & Troubleshooting] eurotig:
I am really amazed !!! So many smart guys are here at XDA and nobody found solution to this problem yet? I cant believe Samsung did not find a solution to this yet..... they live this problem in fog.

Hundreds maybe thousands of people have this problem with their Micro SD cards all over the new are many forums with this commune problem. I have search and did not find a solution nowhere.

I got my S3 about 2 years ago.....I purchase at that time a Kingston 64gb, class 10 card for it. Worked for few months and started whenever I try to view pictures from it to unmounts by its self. I restart the phone and work for few minutes then again disappear. I format it with laptop in FAT32 ....work for few days and then die all the way that could not format with the laptop anymore. So I went and exchange it with a new one, again this one I did from start Fat32 so wont be problems.....again die on me this second brand name card. SOOOO?????

What is the solution? Anyone?

I intended to upgrade now to S4 black edition since I don't like anything about S5 but I read on internet that S4 may have same problem...so I think I will wait for LG G3 because it sound very promising compare to Samsung crappy phones and their slow reaction to solve a problem.

[Galaxy S III Q&A, Help & Troubleshooting] eurotig:
If you read the whole forum and other forums you refer to you can see that is not only SanDisk we are talking about and not be busy just to push the rules on me. I did publish this on every forum with this subject because some people follow certain forums. Is not my fault that they have open more forums with same subject.

So for future be more informed before making a affirmation so you don't look out of place and let the moderator to correct me if I am out of place. Better off you should look for a solution to this problem and actually help the forum.

Lets talk constructive.

FORGOT TO ADD !!!

People from all over the world.

I also had 2 brand new cards killed by my GS 3 international version. Never did nothing to the phone and whenever Samsung sent updates I did them. My both cards Kingston 64gb, class10 are killed and I am afraid to buy another one , so I go without card.

Why don't we all get together on one website or somewhere and sign a petition and make a complain to force Samsung to call back all our S3, S4...etc. phones that kill cards if this is a hardware problem or to release a update if is a software problem.

There are thousands of people on many forums having problems with this same matter but Samsung is just ignoring us one by one and every time they say they never hear of this problem, or they blame the card manufacturers.

Maybe the card manufacturers can support us on this because they ma be tired to keep exchanging cards for free because Samsung cant make a product right and don't want to fix their problem. Or they can actually come and support us with some study by their technicians that can actually prove this.

Dumb people that come to this forums and claim strong that: " this is your card fault, maybe you buy non brand, maybe is fake, or is user fault" without any technical knowledge or any study but they come to talk just so they can look important or just so they can contradict someone ....please stay out because soon will be happened to you also ...soon.

I was thinking to buy t=he new S4 black edition since I did not like the new S5 they came out with but after reading this forums I think I will wait for LG G3 to come out , I think is more promising phone. Forget this ignorant people from Samsung and their phones. No wander their stock exchange go down day by day.

Awaiting for solutions and actually someone do something then mass e-mail all members that participate on all this forums.

I am using a Galaxy Note n8013. In the past years 3 micro-sd cards have been distructed.

Well you bet that my Samsung Avant which is an S3 Module Phone unfortunately had a 5 Year Old 8 GB SanDisk SD Fail on me unexpectedly this morning, Apparently I am not just pointing out the S3 Phones are having problems, but the majority of Galaxy Phones seem to be more of the problem than of the SD Cards, and I know other Brands such as LG, Sony, Nexus, or even HTC would have less issues with the SanDisk SD Cards,

But what I feel is that another issue that can cause Gridlock is Samsung KNOX using Internal Encryption that is installed by it's Unknown Secure Format on the SD Card that causes Increased Failure Rate on it, I swear Samsung KNOX will stop at nothing to make problems on SD Cards besides making them fail on S2 and S3 Phones, Maybe later ones too.

S3 is not fully compatible with ExFat and NTFS. Most card is pre-formatted to ExFat. Solution format your SDcard using Fat32 on your PC. NOT using your S3. S3 default format is ExFat even though it is not fully compatible with ExFat
[Galaxy S III Q&A, Help & Troubleshooting] dstech:
I have a class ten 64GB SD card and it doesn't stay mounted. I read somewhere that the class ten was the issue. Any truth to this? I also formatted using PC to Fat32 but it still continues to unmount after coming out of dormancy. I think this may be more of a hardware or software issue with the phone and not the type of card. Although my 16GB SD card never had this issue.

Also it sometimes says the card is damaged but all I need to do I'd go back in to the system menu and manually force the phone to remount it. Works every time.

I have a 32GB class 10 card from Samsung. Unmounts every once in a while. It usually coincides with Android Media Process going wild and runs at 75 percent cpu continously. Don't know whether one is causing the other.

I also found that if I hold the phone with one finger on each corner and twist gently, the card unmounts "unexpectedly". I mean very gently, like no pressure at all. I can easily imagine the phone getting "twisted" like that while in my pocket.

Please dont blame the phone for the faulty sd cards. I have bought cheap and expensive but fake sd cards in the past and they get corrupted within few days in any phone or memory card readers as well.

False

SD Cards almost always come preformatted Fat32 (Excluding XDHC 64GB from sandisc)

Default phone format is Fat32 on 32GB and Less and ExFAT for 64GB

ExFAT has less issues on the phone than Fat32.

I had an 8gb card I used for over a year on my galaxy s and now I'm using it on my s3. It worked perfectly fine on my S, but now on the S3, I occasionally cannot delete files. I can put files in and download them perfectly, but I can't delete certain files.
[Galaxy S III Q&A, Help & Troubleshooting] Squall-Leonhart:
reason for that is the files are exposed virtually via the devices media storage database.

when you delete files via the phone or via the i9300 device in windows it is letting the media store handler handle the removal of the file.

clearing of the mediastore database or using rescan can often correct glitched database's allowing for deletes to work again, then again, inherent bugs in FAT32 itself can cause deletes to fail.....

Just got my new 32gb class 10 card replaced by Sandisk under warranty. The last 32/Class 10 was effed up 10 days back. Had bought brand new in August. I was wondering how it could happen as i've been using 4/8/16gb cards on my previous phones for years. Luckily someone on other forums told me to try it in a Digital camera as they can still read some corrupt cards, even though i didn't have any DC, i had my 3D/HD media combo player based on linux/Android hybrid. AFter couple of plug in plug out i finally managed to see the folders in the file manager and managed to recover my nadroid/apps/music/photos and other back up stuff (over 7~8gb stuff).

Took the card to the retailer and they said they'll send for testing and let me know in a week. So got my new 32GB/class 10 just yesterday.

I was hoping it would be one off stuff but just saw this thread and it's now making me nervous. I've been using my S3 since may 25th and with 16gb C10 card and then in August i got the 32gb one.

What i remember was i had installed the 4.1.2 updated Omega ROM while connected to the PC. Had been transferring some stuff and when it all finished, i unplugged it w/o hitting the windows safe to remove device option (i always do) but this time there was a brief msg on phone saying some error or soemthing. Anyway i did'nt think about it much and went to recovery to flash some mods. THere when i tried install zip, it kept putting me back in the same option instead of showing me the directory. Well to cut it short, the card could 'nt be detected in windows PC/notebook/other phones/TV.

Sorry for the above bit of text but hope it helps and incase we need to send the msg to Samsung about this issue.

Edit: BTW i remember seeing msgs like SD card removed a couple of times over past few days before it gave out. Any of you guys noticed any missing files or msgs of dimounted cards and on what ROMs were you on?

My first 64GB SanDisk died after about 4 weeks of usage. I noticed something was going wrong as CWM would not find files that I previously copied to the card.

SanDisk replaced the card under warranty though.
