[Q] ICS no option for Encryption on SD Card?

Hello all,
I have Sony Ericsson Xperia Neo V.
So I upgraded the phone to ICS 4.0.3 and it seems I cannot find an option to encrypt phone under settings > security.
What I have found is this:
If i connect to pc through usb I need to enter my screen password in order to be able to read the SD Card.
BUT, when I remove the sd card and enter it to an external card reader ALL data are available.
Is there no option to fully encrypt the SD Card in ICS?
What the heck?

in fact, even the google stock ics doesn't support external Sd card encrryption too.
the reason why you must input the screenlock password to make Sd card visible when you connect your phone to pc is that you are using MTP connection mode, the mode will hide the storage units unless you unlock the screen. that's to say, if you change the connectivity mode(Settings->Xperia->Connectivity) to MSC, Sd card will be visible even you don't unlock the screen.
P.S.
#in MSC mode, only Sd card can be found, since internal storage doesn't support the MSC mode.
#you must unplug the usb cable or you can't change connectivity mode

Thank you for your answer!
So far you were the only one who gave me an insight on what's happening.
And thank you for letting me know that the sd is not encrypted but "invisible".

Get data from sd card fromatted as internal(Android 6 Marshmallow)

I have a micro sd card 32gb Transcend which I use as android internal memory and was working for one year.
Yesterday suddenly stopped working and my Motorola moto g(3rd) device not recognizing it anymore.
When i insert this card and starting my device it shows that it "checking" it for 2 minutes and then it shows "no card".
I would like to get my data from this card(photos and videos) is there a way?
I have a second moto g device to which when i insert this card it shows "cannot read card" and asks format "as internal" or "as storage"?
If i choose "as storage" i will lose my data?
Please move this post to the appropriate thread.
thanks for helping

The card was formatted as internal before it was stopped being recognized. So the card is tied to that phone and is encrypted. No matter which of the options (adoptable or portable) you choose, the second Moto G (or any other marshmallow phone) will format it first deleting all the data. I am not sure if you can recover your personal data though, sorry.

Welcome to the joys of adopted storage... It puts incredible amounts of read/write cycles on the card, causing "early" failure. Really this is not early failure, sd cards have limited writing capabilities and using adopted storage does this causing failure.
When you use adopted storage, the data is encrypted to that device and there is a decryption token generated that is stored on the device, for whatever reason that encryption token is no longer valid (likely due to a failure of the card) and the data is lost.
Your card can no longer be trusted, I would suggest replacing it.
This is another reason why regular backups of data, both manually and automatic, are essential in devices. I suggest implementing a backup plan in the future.

Is there any application that can get this "decryption token" from device and read the sd card?

Nope. The purpose of encryption token is to prevent the use of card in other systems. It will take a great deal of hacking to get the token and put it into another phone, that too if it's possible at all. The token is randomly generated AFAIK and is not supposed to be used between different devices.

Not really... IF (and that is a big if) the data is intact AND you are rooted already, the token can be retrieved via an ADB superuser shell, then you need to have a modern Linux installation that has a microSD card reader and you need a fair understanding of using the command line and mounting an encrypted file system manually. The big if here is if the file system is not corrupted, but if it wasn't corrupted then the phone would be able to use it. Also, if you are not already rooted (actually, your bootloader unlocked) then the process will wipe the device including the decryption token.

If I unistall from my device applications that used to be in sd card, is there any chance for sd card to work again?
Thanks for your replies

No... If it can't read the card it can't use it. The fact it's checking for so long says it can do something with the card, but that operation if failing. If you are already rooted there maybe some options of manually doing an fsck but other than that the best you can hope for is to reformat the card in another device and salvage the media for non-critical usage as standard storage, but the data is lost
You could try rebooting several times, you might get lucky and it will mount by chance, but don't much hope in it.

My GF has a Moto G3 2015 (1GB RAM, 8GB storage) which I had configured with a 32GB SD-card as adoptable storage. After this month's OTA, the SD-card is no longer recognized and there seems no way to recover any of the data. It also checks a couple of minutes for the SD-card and then says 'no card'. If I put the card in an adapter and a Windows pc, it says the card is healthy in disk management but it does not show the card in Explorer, I guess due to the formatting and encryption.
This is the second time her phone has issues with adoptable storage. First time the internal storage was full while there was still plenty of room on the SD-card, but this was apparently because I had only configured the SD-card as adoptable storage after 6 months of use, which caused the internal storage to have filled first. I expected adoptable storage to treat the internal storage and SD-card as one, but this is not true. I gave the phone a factory reset and immediately set the SD-card to adoptable storage before installing any apps, this took care of the problem until now.
I would not recommend using this option on any phone. Just buy a phone with enough storage and use the SD-card as external storage which is what I do on my Honor 7. I had told her to wait for the 2GB/16GB version which was going to be released a couple of months later but you know women, once they have their mind on something, they can't wait .

URGENT HELP NEEDED! SD Card Encryption & Decryption Issues

Good morning folks,
I'm hoping XDADevelopers can assist me with an issue I've brought onto myself past couple days. I'm praying something can be done to recover my files! :crying:
I have an Galaxy S8+, and I encrypted my phone using Android's encryption feature (with a 4 digit pin code), and for some reason it wouldn't allow me to decrypt it. The option remained as 'Encrypt SD Card' via Settings > Lock Screen & Security > Encrypt SD Card, but when you go into it, it said that it couldn't decrypt the device as it needs the same device used to encrypt the SD Card in the first place confused:what? It is the same phone!!!). Burning up the internet trying to find a solution, I came across several forums telling me to do some of the following:
- Change Screen Lock Type to 'None' then try again - Failed
- Backup contents of SD Card onto PC, format SD Card on phone, encrypt SD Card (using 4 digit pin code), copy contents from PC onto SD Card, then decrypt it - Failed
- Wait it out - Failed
- Enable Developer Settings (I always do for the record) and enable 'Stay Awake' / enable USB Debugging, then repeat option 2 - Failed
- Mount / Unmount, reboot, etc. - Failed
When it was encrypted without any files on it, the option was now Settings > Lock Screen & Security > "Decrypt SD Card", so it seemed like an initial error occurred that made the SD Card think it was encrypted from another device,
Now the only copy I have of my files are stored on PC with no way of accessing it :crying:
I haven't formatted the phone yet, and I'm very reluctant to do so in-case i cause further damage.
Right now I'm in a constant loop of trying option 2 in hopes that it suddenly worked and allows me to access the photos! it managed to work once, but couldn't let me open the files from QuickPic app.
My questions are:
Can I recover my files? (from my PC)
Is there a way of forcing the encryption and encrypted files (stored on PC) back ONTO the SD Card after having formatted it?
Is there an app (either on phone or PC), that can force me to enter the 4 digit pin code (which was my phone lock, along with fingerprint scanner).
I'd very much appreciate any time and response regarding this.
Many thanks!

Hi.
I understand that it is unlikely that I will already help the author of the topic. But maybe my situation will be useful to someone else. Faced the same problem as the author. My memory card started to fail. At first, the phone lost her, but was found again after sd card being remounted. Then after some time the phone lost it again and did not see it at all. In this case, my laptop saw the card. I found that the problem is in LOST.DIR. Now the phone began to see the card, but it gave an error that the card was encrypted on another phone ("this sd card cannot be decrypted because it was encrypted on another device") (maybe the problem is that I inserted another card to check if this is a problem with the phone’s hardware). I tried the steps described above and the error reappeared. I tried to format the card and copy only a part of the files from the image and came to the conclusion that the problem is in one bit file in the DCIM/Camera directory. The phone apparently tried to scan the gallery on boot. It received a decryption error and stopped decrypting the rest of the content and just said that the keys are not the same. As a result, with long attempts, I found a broken file and successfully restored all other files.

Adopted SD card, forgot- recover data?

Hello guys,
My partner changed her SD card without realising the exisiting one was "adopted" as internal storage. All of her photos of our kids are on there. She clicked "forget sd card" at the prompt without realising this makes the SD card essentially useless to recover the data.
Is there any way to recover this data? Obviously the PC does not recognise the SD card as its encrypted, so we cannot pull the photos off that way. The phone asks to format the device so I cannot pull the photos off with a usb cable either.
From what I've read, the phone generates a key for the encryption using the screen unlock pattern. We know what this is, so have a chance of unlocking the SD card as we know what the master key is. The phone is not rooted- as far as I know this changes the encryption on that end, so any attempt to root the phone to get access will not work as the keys will not match anymore. Are there tools to brute force the encryption on the SD card? I would hate to lose the data on this.
Thanks

Encrypted SD Card

Hi,! I have a galaxy note 8, this is the problem I have:
I encrypt my sd card from the mobile (sandisk extreme 32gb sd card) android system version 9,
I have a problem right now, it doesn't let me decrypt the sd card,
when I'm going to decrypt, I don't get that option, I get the option to encrypt... (as if I hadn't encrypted it before)
I do not understand what could have happened, I can enter without problems and see the files of the sd card, but when going to open a video or file of the sd card, it is not seen (because it is supposedly encrypted)
I hope someone can help me

U should of never done that in the first place like who encrypts a SD card

Hi, I have been checking all the files on the sd card thoroughly, it seems that it has not got to encrypt all the files, I can listen to some loose songs, and see some loose things, but in a percentage I can agree to see 15% of the sd card 85% is encrypted, is it possible that it has encrypted badly? And is it possible that security patches, having installed it had to do with this problem of decryption? (it just happened I installed after encrypting in android security patch), hopefully someone can help me
