[Q] SD Card Encryption and pictures files help

Hi dear experts,
Wondering if someone can suggest me if there is any way to recover some picture files from encrypted SD Card.
The issue is that I'm having some problems with my phone connecting to the cell towers and I was trying to show to the Samsung tech support remotely, he ask me to factory reset the phone and I forgot that the SD card was also encrypted with some pictures that I'd like to save.
I red somewhere that some phones or Android versions use the Serial number + the encryption PIN to encrypt the storage, so I encrypt again the phone using the same PIN, then format the SD card, encrypt the SD card and then copy the files from my backup folder in my PC putting the SD card in my PC, copy the files on the PC then install in the phone but still the files are not able to decrypt.
The phone is using the latest standard Tmobile ROM 4.1.2.
Thanks in advance.

How good is the SD Card encryption feature that comes with the phone?

Under Settings > General > Security
I have some questions regarding the encryption
If I encrypt my SD card:
Will new files I transfer from my phone storage to the SD card be encrypted automatically? Or will I have to re-encrypt the entire SD card
How do I de-encrypt the SD card? Can it only be done with the specific phone that I used to encrypt it? Meaning if I encrypt my sd card, and my phone breaks in the futute, I'll never be able to de-encrypt it?
Can I access files on the encrypted card using a file explorer? If so, do I have to enter a password every time I want to look at a file?
That is all. Thanks you in advance.

Encrypted SD Card, quick Q&A.

I just got a 128GB SD card and I decided that it is a good idea if I encrypt the SD card, since the device is already encrypted. I didn't encrypt my last card, just for the record.
Anyway, I'm familiar with how Android Encryption works, I know the risk, I backup my phone regularly, and I know that putting the SD card DIRECTLY into another device or PC is not an option, anymore. Only my G4 can read/write to the SD card while it's encrypted.
Problem is this, I ASSUMED that so long as the SD card is in the phone and the phone is plugged into my PC, I could make file transfers between the SD card and the PC (the phone would handle the encryption process). No such luck. I have no way to transfer files between SD card and PC, unless I decrypt manually.
Any suggestions?

I just can across this same issue last week and have been hunting for an answer with no luck. Have you found any?
I though i could move files around internally and the OS would handle decrypting the files as they went from the SD card to the internal storage. I was a bad assumption. I want to encrypt the SD Card, but I cant move files onto or off of it.

SD Card formatted automatically and data copied over

My friend took a full sd card from a camera with photos and put it into her phone to view them...
She said, that the phone started formating the sd card automatically and copied all internal data over to it.
I doubt, that there was no promt showing the formatting dialog. However, I am not so sure about this "data copying".
Is it possible, that data like photos & co are copied over to the sd card automatically? And if so, is there a way to copy them back?

She made one mistake: she selected to use the SD as adopted storage. She should have chosen the removable option.

I googled adopted storage and found this:

Is it true that there is no way to copy the data back? Its not her sd card after all.
Its said, that a factory reset will solve the problem. What is lost when doing that? How do I do it without loosing data?

I know how to recover the photos from the sd card - no problem with that. But I dont want to reset the phone to get it back working without the card.
And if I need to, I would like to not loose any data when reseting

External SD-card encryption without being set to internal/adaptable storage?

I’m wondering if there’s a way to make the whole sd-card encrypted and the android system recognizing it as an external sd card? The purpose being that data is safe if the phone would get lost/stolen. I’ve been looking into this guide using cryptsetup, but it only works with an image, and only part of the SD card.
