I have a nokia 3.2 with android 10, one day the lcd suddenly has dead pixels. I took out the sd card and did a device reset(like the old days). Then I sent the device for repair.
A few days later I got the device back, but then I realized that the sd card cannot be recognized by the device or PC. I have learned that it may be encrypted. Is there anyway that I can get my photos back?
The picture in the attachment shows the image created from the sd card open in 7z. the "android_meta.img" contains no data inside.
Any help is appreciated. Thank you.

Thanks for the info. I am afraid I don't have the key anymore. Brute force maybe the only solution.
In case of unreadable SD card (not an encription problem) a distinction must be made between corrupted File System and physical failure. In the first case the raw data are still accessible and a recovery SW tool is able to restore the files, maybe assigning them arbitrary names such as "file0001". In the event of a physical failure, the SD internal memory chip may still contain data, but the electrical signals between the SD connector and the memory are damaged; in this case the data is irrecoverable. Fortunately, I found a German site https://recoverfab.com which, in practice, uses a Laser to open the SD, then connects the memory chip to an external circuit and retrieves the stored data. Of course, the operation has its cost, but if the data is really important it can prove to be a salvation.

Hey all,
I just discovered the option to encrypt my external SD card in Android. I like the idea as without it anyone can get data off my SD card if they steal my phone.
However, if my device ever dies presumably that card will never be recoverable as the decryption keys will be lost with the dead device. Is there anything I can do pre-emptively to protect myself from this scenario?
Presumably the encryption keys are stored on the phone somewhere. Can they be backed up and stored on my PC or something to ensure I can always recover the SD card later?
I own a Samsung ON 7 phone and I was using a class 10 Sandisk memory card which was encrypted by the device in the lock screen and security menu and with no other third party software. Now I have done factory reset on my phone and accidentally forgot to decrypt the SD card, now SD card is detectable and all the files are there and visible as well. but i can't open any file. What to do, please help ! :crying:
Are you sure you have permissions set correctly? Can you just plug your phone into a computer with a USB cable and move the files over that way?
Also, those Sandisk SD cards are crap. I had a few of those cards and every 6 months they would fail and go read-only I/O error, never with more than 25% of the space used. Your card could just be being a Sandisk.
DIsclaimer: I don't actually know what Android uses for encryption, I assumed LUKS or something similar. It's possible that Android has the dumbest encryption scheme ever and lets you see the filenames in an encrypted volume, but that seems really unlikely.
I was in a similar situation recently and was looking for advice on the forum. I connected my SD card to a PC and restored the files using the Uneraser program. I think that this option can help many.
Hello,
I've a µsd card (Samsung Evo 128GB, formatted as adapted storage+external SD).
On my pyrotab running MM6, it randomly unmounts the external SD (transport endpoint is not connected in the log).
Pretty annoying. For a few weeks the problem was less frequent (usually on the second reboot the sdcard is ok), but now, the card disappears after a few minutes, not enough time to perform a Titanium backup :/
Anyone else experiences this ?
Any hint ?
Adapted storage. That is never a good idea for multiple reasons. Once the SD chip corrupts all your data is lost. Moreover, it can slowdown performance.
You could try to clone the SD card on a PC, I'd say. If it works, backup all your data and forget about adapted storage.

Yes, that was my idea and use Link2SD/Apps2SD to move app and data to external storage.
But any hint on the SD unmounting issue ? I fear I'll have the same problem, as it's the FAT partition that gets unmounted, not the adapted one.
Multiple partitions on one SD card? Or two SD cards? If so, via otg?
In general, you cannot remove the adapted storage SD card! It will compromise the system.

I use my phone mostly to recieve A LOT of work documents, photos, audio, etc via whatsapp.
So, i thought in get a SD card and format it as internal storage, since what i need is just a lot of storage to save as much data as possible, not gaming or anything of the sort.
The issue is, since it's formatted as internal storage, connect phone to PC via USB won't let me see the content and i have no way to transfer from PC to phone OR from phone to PC.
I want to know how to transfer whatsapp photos/documents/audio/etc on a phone with SD card formatted as internal storage to a PC (without dropbox, google drive or other cloud service, since this is work data it's a big no-no to use cloud sharing), or if it's just not possible. Same if it's possible to send files from PC to phone.
Don't know. If you can't directly access it and use recovery software instead it will make a mess of the data ie no file structure. (Edit, see post below.)
In the future don't use it as internal memory, it's too slow for one thing especially write speeds.
Apps, DCIM and download folders go on internal.
All critical data goes on the SD card. The DCIM folder data is regularly transferred to the SD card but never name that SD card folder DCIM.
The SD card is then redundantly and regularly backed up to at least 2 hdds that are physically and electronically isolated from each other and the PC.

While adopting a storage, whether an SD card or USB drive, Android formats and changes it’s FAT32 or exFAT format to ext4 or f2fs.
With Adoptable Storage, Android encrypts the external SD card or USB drive being used as internal storage, thus, it gets tied to a specific Android device. The key used to encrypt the data on the SD card is stored on the Android device’s internal memory. So, it is NOT possible to mount the adopted storage to another device because of its encrypted nature.
The adopted storage becomes an extension to Android's internal /data partion what at any time can get accessed from PC.
I broke my screen and when I connected to pc through adb i was hoping to access the sdcard. it was formatted as internal, i didnt know better at the time.
somehow it got factory reset and i didnt know. ordered new screen and booted up and it was reset ahhh. memory card says needs formatting. phone has lineage and is or can be rooted and phone works fine.
in this case, is there any way to access the sdcard ?
thanks.

If it was factory reset then the encryption keys were lost. Not retrievable.
thanks for the reply. i will stop crying and move on. i like closure.

It sucks. I've lost a 30 yo database that was irreplaceable. Just play time in the hurt locker...
Always backup critical data redundantly and regularly to at least 2 hdds that are physically and electronically isolated from each other and the PC. Never encrypt data drives.
yah i try but was motorbiking in baja mexico for a month and lost all the pics and all my text messages. nothing critical like an old db but still lots of fun memories ... im old and need pics to remember
but everything went wrong. i think i recently updated the phone with lineage and when i came back adb wasnt authorized anymore so i couldnt access the phone for data copy. usb-c to hdmi didnt work... could have been so simple if things just worked ... android has become as frustrating as my one and only iphone 3g . thanks again.

You can always carry two .5tb OTG flashsticks for backup. Not as reliable as hdds but much better than nothing.
Generally unencrypted SD cards are very reliable if not removed from the device. Sometimes important lessons come at a high cost.
I have an interesting phenomenon. I want to upgrage an extFAT 256 Gb SD card to an extFAT 1 Tb SD card. The source and the destination cards are not encrypted. I copied all unhidden files from the old one to the new one via a USB reader. I can see everything on my 1 Tb card. When I insert the new card to the phone, some folders like download, music or video are empty. I remove the card from my phone and put it to the same USB reader. These directories contain no files. It looks like you cannot simply copy files. Of course, I can copy them connecting my phone via USB; however, it will take a day to transfer 65 Gb of data. Disk imaging is very slow too. I'm on UI 4.0 Stock, Note 20 Ultra.
Format and load card in the phone.
You need a V30 rated card for best speed.
Thanks! No, it does't work. I've done it the same way: format on the phone / use very fast card. Copy to the phone speed is 700 Kps, via USB reader - 7.5 Mps. I'm afraid it has something to do with the card ID xxxx-xxxx. Volume ID changer doesn't work with new SD cards.
All I do is get a Sandisk extreme, format in phone and it's good to go.
I'm running two N10+'s, one running P the other Q. Using a 512 gb card.
In phone transfer speeds are about .5 [email protected] Average about 1.
Try going from internal memory to card. Should be about [email protected]
Check the PC, use the SmartSwitch driver.
Access SD card drive in the phone using Windows Disk Management, scan for new devices, load/download from that window.
Check Event Viewer for error messages.
Try clearing the system cache.
The story is even worse. I have a 512 Gb os Internal Storage version . I copied my SD card to it, put a new SD card and copy all my files from external to SD. The copy process was fast I was able to see my files on the new SD card. As soon as I deleted a copy from the Interatal Storage, my files were automatically erased from the SD card.

I trust you have redundant copies saved on hdds...
How fast? The card's top speed is around [email protected] Sounds like it was just deleting the files, not writing them to the card.
Try in safe mode.
Run a Check Disk on the PC. Do a low level format and always format in the phone before use. A 3rd party app maybe more helpful for low level formatting.
More ideas.
*always keep the possibility of a virus or rootkit in mind when you observe unexplained behavior with an Android. These are very rare unless you do something stupid... as we all have.
If one disk or more are suspected of being compromised keep them 100% isolated from the backups!!! As they should be anyway.
It's also possible a hidden user setting was altered. Poorly written 3rd apps can do this, unistalling may not fix it or could even trigger it.
Factory reset to clear the user data and reset everything to default. If you did any major firmware upgrades and you didn't factory reset... it's time to.
I don't advocate factory resetting normally at all but for the above issues sometimes it's the best option for a stock Android.
If you can find the app that alter the hidden user setting you may be able to repair it sometimes by reinstalling the app and toggling the setting in it that triggered the issue than unistalling it again, if it's an option. I've done this before, in fact it was on the current load I'm using which will be 2 yo in June. I prefer to find the issue rather than nuke whenever possible... to prevent reoccurrence.
Thank you! I've found the problem. I had to disable zip compressed folders functionality on my PC using a registry fix. Obvously, the phone doesn't support this feature.

Lol, you had me worried as I'm thinking of up sizing to a 1tb card on my N10+
Never encrpt, compressed or clone data drives especially media files as bad things tend to happen. Those silly little null marks matter
