Decrypt SD Card - Samsung Galaxy S8 Questions and Answers

My phone's screen is dying and I cannot view anything from the display.
I want to transfer everything in my SD card to my new phone but unfortunately the SD card has been decrypted.
Is there any solution to decrypt my SD card without the phone screen?

I think you can't.

Question on SD Card usage

I remember reading a while back that the SD card might have to be formatted in some weird way to do something.
Is it possible to just use a fat32/exfat formatted card in the phone as pure storage such that it's still 100% readable on a computer?

SD card not working

Hello, I'm new here.
I'm using Moto X Style Indian version with Android Marshmallow from last 5 months. I'm using "SANDISK ULTRA microSD UHS-I CARD" with format as internal storage without any problem, but now suddenly a notification show up that "Insert your SD card", I even didn't remove my card since I put it once. I tried to insert my SD card to HTC phone, saying "Damaged SD card" with only option for format it. (I'm not able to take screenshots or click any pic)(SD card is still in my moto x style but in setting it shows "Not Inserted".)

Welcome to the world of adopted storage...
Try to power off the device, remove the card and reinsert it, then power back up. If that fails, either the card has failed or the encryption key has gotten corrupted or "lost". There isn't a lot you can do to save or resurrect it if your device doesn't see the card and unencrypt the data.
When a card is adopted as internal storage, it is encrypted and uses the ext4 filesystem, it will only work in the same device with the same key and cannot be read in any other device without formatting it back to FAT32 and wiping out all the data. There is some information here about reading the data with a Linux computer, if you have the appropriate card reader and can access the encryption key on the device.
Thanks for your reply @acejavelin,
I tried everything turn my phone off, eject card then reinsert it, still same error. Now what to do? Will I format my card with FAT32 by attach my card with PC? I know my data will not save... but I have no option.

Yes... Reformat it in a PC or in another device. Personally, I would not reuse the card, especially as adopted storage, since it can no longer be trusted.

Ok, I will also not use this card again with adopted storage. Thanks for your suggestion @acejavelin .
Seems my problem will be solved , but all my data will loss :crying:
Sounds like the problem is with your phone's SD card reader, not with the card itself. Other computers / phones will tell you the SD card is damaged/corrupted because they cannot read it (the card is encrypted), but that doesn't mean the card is actually damaged or corrupted.
You won't be able to extract your data from it unless you can get it to read the card again. I would try popping out the sim /sd card tray and shoving it back in many times, to see if eventually it will read (mine takes 2-3 tries before it will read)
If you can't get it to work you may need to contact Moto support to get a replacement under warranty (assuming you haven't unlocked the bootloader / voided the warranty)
Definitely try another card though if you have access to one, just to check and see if it will read a different card.

Micro SD Card Handling

Anyone know what the phone's behavior will be when I insert an SD Card? Usually I would want to format the card with the phone if I'm going to keep it in there 100% of the time. But right now, I'll be removing it now and then.
Can I just plug it in, and the phone will recognize the directories that I already have on the card if the card was originally formatted in Windows? Obviously I can back up my SD Card first, format it on the phone, and move my stuff back to the card after.. Just wondering what the best way to go about this is. I haven't had a phone with an SD Card slot since my GSIII.
As long as the card is exFAT format it shouldn't be an issue. It will detect any media in it and display it accordingly (well should).
If the card is NTFS formatted, it won't work
if it a fat32 memory card you can cross-swap as much you want. You do not need to format on the phone... I never really did ...
I pulled my SD card out of the Note 7 and dropped it into the V20. No problems.
Cool. Thanks!
Will the card once inserted be encrypted or can it remain unencrypted in the v20 ?

SD card formated as Intenal Storage not recognized in new XT1767PP identical phone

Have multiple Moto E4s XT1767PP unlocked Verizon phones. Needed to replace one so I moved the SIM card and the 128GB SD card formatted as Internal Storage and containing many pictures and other data to the new phone.
Phone booted and recognized T-Mobile SIM card but displayed a message that the Samsung SD card was not recognized.. Contacts seemed to be there and the new phone made and received phone calls.
Went into Settings/Storage and was asked to format the SD card. Did NOT FORMAT the SD card as I did not want to destroy all the data recorded on it.
Shut down the phone, removed battery and SD card and inserted another SD card. Replaced battery and rebooted the phone. After it came on went to Settings/Storage and formatted the new blank SD card as Internal Storage,
How can I get the original SD card and its data to be recognized by the new XT1767PP phone?
If not possible how can I get the data backed to my Google.com account to be transferred to the new phone?

The only device that will recognize and read and decrypt that SD card is your old phone.
