    Default Decrypting External SC Card on Galaxy S3

    I had to encrypt my SC card for work security & have since gotten a new phone. I am unable to see the photos & videos on the SC card now. The old phone has been decrypted & reincrypted both with and without the card in place. The phone still shows the # of photos in the folder but when you open the folder it shows only gray squares rather than the images. When I tap on the individual squares I get a message that says "unable to load photo".

    I've done some reading & am gathering the encrypting is irreversable but am hoping someone out there knows something I'm not finding. Of course there are irreplacable photos & videos on that card.

    Any suggestions are greatly appreciated.

    I'm pretty sure that you have to decrypt the SDCard on the same phone that it was encrypted on. If you no longer have access to that phone I think you're out of luck.

    I have decrypted it on the original phone with no success. I'm really thinking all these photos are gone. All 1730 of them I'm just sickened. A very important lesson has been learned though....back anything that means something to you up. I know better than this.

    I have the Note 2 and encrypted my device because of work email. I am having the same problem as you since I actually reset my device this morning. Sad. I found an forum before the reset that mentioned something to download to decrypt the sd card....but cant find it right now. I just wanted to let you know that there is (apparently) a way to regain the sd card access.

    Im keeping my fingers crossed. I have alot of pics as well.

    I think this is an interesting thread and I think there might be a solution. I was wondering if maybe truecrypt would work to decyrpt it. Truecrypt uses many different types of algorithms to encrpyt data. I was wondering what of algorithm the galaxy uses, probably something like AES. If so, then i see no reason why you wouldn't be able to mount your SD card to your computer and recover your pictures. That's actually what I was doing now was researching to see if it was possible to do this as i was preparing to encrypt my device

    I have the same problem but on the Samsung Galaxy S4. Encrypted the phone, had the SD card in it, had to factory reset the phone and now the files on the phone are there but do not show the images - just squares. Anyone have a clue? Cheers

    I thought encrypting the phone and encrypting the SDCard were two separate/independent procedures, but I've only fiddled with the SDCard, and that didn't end well (64GB SanDisk Ultra ended up totally corrupted/unusable).
    If encrypting your phone caused the SDCard to also be encrypted then it sounds like you need to provide the correct key to get your SDCard returned to a normal state.

    Hi Guys, Im also IN
    I've encrypted my Galaxy S4 coz of official email security and then memory card as well. Now I sell the phone and the data on memory card is there but cannot access the photos and other files on it.
    Do I need to decrypt the memory card on same phone??

    Need some serious help

    As stated above, yes you will need the phone that encrypted the card.

    I have the same phone, but I had to reset it to factory settings due to some issue with the phone.
    I had unmounted and removed the SD card prior to the reset.
    Is there a way to decrypt the SD card on the same phone, after the phone was reset?

    Thanks.

    <- This is the point at which you should have decrypted the SD card - before you removed it and did the Factory Reset.

    It's been quite a while since I fiddled with encrypting an SD card (it didn't end well - it corrupted my 64GB card and it was completely unrecoverable, even in a PC), so I don't remember - did it request a password?

    When you insert the encrypted SD card in the phone now, does it prompt you to do anything with it?

    Ok, here's my problem:
    I attempted to encrypt both my phone (Galaxy s3) and my sd card. Once complete, I couldn't access my sd card. So, I attempted to decrypt my sd card. As of right now, it's apparently still decrypting (Day2). When I hook my phone to the comp, it doesn't even see the sd card, let alone show any files. I just want access to my sd. I've got thousands of photos and songs on it. Am I screwed, or should I just be patient?
