    So... I have an update on my situation. I had to pay my bill yesterday, so I stopped by my local Verizon store. I mentioned the fried SD card to one of the sales techs and they asked if the SG3 ever got hot. I said yes it had and that I remember it being hot on the day the SD card fried. They immediately claimed that my SG3 should never get hot... warm, yes... but not hot and that the issue is normally a battery problem. When the battery goes bad, it overheats and fries the internal workings of the phone... the SD card can go first. I now have a new SG3 phone and battery coming to me. I was told not to use any of the 3 batteries I have because it was obvious one was bad and the others could have been affected also. Has anyone else heard of this?

    I had an SDHC card go bad. Replaced it with an SDXC 64g card. So far, all is well. I did not format it, and leave it in the phone.

    Hi guys - I realise this thread is a few months old. However I found it after trashing 2 x 64GB SD cards in my new Samsung Galaxy S3 4G (i9305) after a couple of days. Thanks Babelfish for getting the Sandisk technical report. In my mind it points to a poor power supply as the "smoking gun". In my case, the cards failed during recharging on the integrated USB port I have in a bluetooth speaker (brand is "Mutant"). I measured the power supply with an oscilloscope and found some disturbing peaks, and also a significant common mode voltage down to ground (i.e. it's 5V between positive and negative, but both lines had an AC voltage superimposed to ground. This is probably leakage current from some sort of RFI/EMI filter poorly designed in the power supply itself. It's reasonable that activity to the card with a crappy and noisy supply will end up corrupting something.

    So far I've returned to just using the original Samsung power supply / charger and so far (1 week) no issues. I've also junked the speaker power supply and replaced it with something a bit better. I haven't tried charging the Samsung Galaxy on this new power supply yet - I just wanted to confirm firstly that the issue goes away using the standard charger.

    So my suggestions at the moment are :
    A. Only use the original Samsung charger, or another well known and proven brand.
    B. Be careful what you put on the SD card. Try to avoid applications that do lots of read writes (which will only increase the risk of a corruption). In my case, I've just got music on the card and everything else on board.

    Cheers : Greg Smith

    You said about using a proven brand charger. What about apple? I am talking about there wall ext not the adapter.

    Its for the ipad but works well with my iphone. I really dont want to use ext cords


    Edit i plan on getting a 16gb one for music and use my 2gb old school kind for pics i dont take that much.

    Or just use the 16gb for all of them? I might have missed it in a post but its hard trying to read things on my 3.5" screen

    I can say 100% that on my I535, the 32gb Sandisk fried, but it was not connected to a charger at the time. In addition, it was never plugged into anything other than the charger that came with the Galaxy S3.

    I put a new card in almost 2 months ago, same card, just this time I formatted before using in the phone. So far, no problems. *knocks on wood.

    Based on my reading from the site i should be fine with a 8class 16gb mirco sd?
    Some stats from my iphone which i hope to transfer to the S3 once here
    Music 3.8gb
    Photos 768mb
    Viedos 2gb

    For the charger its a apple 10w power adapter lengh is about 6ft (it had saved me more then once already). I know stick with the normal charger. But will this hurt the phone?. The only charger that let me down was apple's i am on my 5th one (apple) and my truck(chager second one non apple) shorted out at the tip of the charger where it plugs in the phone. Is this a issue with the S3's. i ask this because of that post about using chargers. Stock and proven name brand

    Thank yall for the advice

    So has anyone figured out how to get files off of the "unreadable" cards?

    Similar story here, I had a Transcend microSD 32GB card fried up in my Samsung Galaxy S3 (bought card in Reliance Digital along with SGS3).
    I used the card for about three months. I too had signs that there is something wrong with card for one month before it happened.
    Phone was showing message "preparing SD card" every time I woke up the phone, but card was working
    Then suddenly it stopped working.
    There is no way I could damage the card with static charge as the card was inside the phone when the problem actually occured
    When I took it to Reliance Digital, the technician checked the card by inserting it into a USB drive in a computer and confirmed it is dead. It showed zero bytes free.
    I went to a Transcend service center for a replacement. The replacements have to come from Taiwan to India, so they asked me to wait for 2 months !!
    I have all the data backed up and also have a 2 GB card - so am now waiting for a replacement from Transcend.
    Looking at so many posts, I guess Samsung must seriously consider changing the microSD card location in the phone

    Carbon Backup, maybe? https://play.google.com/store/search?q=carbon+backup

    Or possibly SOS Backup? https://play.google.com/store/apps/d...AuYW5kcm9pZCJd

    With a Sandisk Ultra 32GB micro SD in my Samsung S3 no problems at all since nearly 8 months.
    2 weeks ago problems started, card is unreadable in the phone. When un-mounting card it can be read in my computer. At time the problems started I had bought and installed new software (VIRE launcher). After disabling this software (without de-installation) and re-mounting SD card all back to normal. After 2x repeating always same behaviour; with new software active card appears empty, new software de-activated and SC card un-mounted and re-mounted back to normal. (Maybe de-mounting not necessary, but switching of sufficient?) Strange, but good to know...

    As mentioned in my previous post(link), after formatting no problems, now 4 months in. My last one barely lasted 30 days.

    I installed Dropbox and it defaulted to mirroring all my pictures to my dropbox. Unfortunately I thought that was a waste of bandwidth and I turned it off. Now a bunch of my pics in the Gallery are corrupted and I'm wishing I had the dropbox copies!

    My fried SD card problem starts resolving. Corresponding with very competent people at SanDisk they recognized this failure as a card problem and promised to eventually replace the faulty card after they could check it. Very quick replies from those people. When testing my S3 with a micro SD from a different manufacturer the problem did not return... Now I am waiting for the replacement.

    They were very helpful for me also.

    Samething with me. S4 bought 3 weeks ago, and yesterday the SD card fried. I don't think that is an isolated problem. Many people are complaining about the same thing. Samsung should answer this issue.

    My Samsung 8 GB Micro SD card got fried a few weeks ago in my Samsung Galaxy S3. It can't be accessed on my PC via adapter, unfortunately. It had been working fine for over a year in my old phone, an HTC Desire. My SIII is about 1 1/2 years old.
