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.

When you use sd card as an adoptable storage, (galaxy s7) even when i wanna change my sim card, would removing the tray cause a serious system problems? Or is there a workaround. I wanna use adoptable storage to have some more space to install apps but this question in my mind prevents me from doing it.
Can anybody enlighten me with experiences?
Should you format adoptable?
Generally it's a bad idea which lots of manufacturers don't support, and for good reasons. For starters, you'll no longer be able to remove the SD card from the device. This is because Android will store system files onto it. Also, SD cards can only have data written to them a limited number of times. After they expire, your phone will not function properly. SD cards also perform much slower when formatted internally, and it can often cause apps to perform poorly and lag. Some apps won't even work at all, and any other device will not be able to use the SD card without formatting it itself.
Proceed at your own risk.
I really don't recommend that to anyone, (on every phone available)
it really slows down phone. (this phone has 300/100 read/write)
And if you don't have such sd card don't format it as internal memory,
just as SD card for multi-use.
I tried with 100/40 or something SD card,
and it felt like s...
Yes, I can confirm that! My old Phone had only 16GB of internal memory, so I thought that it would be nice if I format my Class10-SD-Card as internal memory.
But it was a mistake, because it slows down the phone so much...
Also if you have a very fast SD-Card - it will not work and slow down your phone...
I've always been using microSD on my smartphones as an internal memory and have no speed issues.
It is also advisable to move all apps to the internal memory and to use the "external" internal memory only when the internal memory is full.
When the microSD is formatted as internal memory, the transfer rate drops because the microSD is encrypted (AES-128).
However, this is hardly noticeable in practice.
let alone that: The advertised microSD speeds are rarely achieved in practice.
I have more problems with a portable formatted microSD.
There are e.g. Access problems with third-party apps or file managers.
Hello. I'm thinking to buy Micro SD card. Sandisk Extreme Pro. My idea is to increase internal storage. I know since Android v6.x is/was possible to move apps to sd card or make it as internal storage. I never tried and used this way on Samsung phone. So I have some questions. How or is it possible to use micro sd card as internal storage. How quick opening, rinning, working applications. And last question what is max video recording settings to work smoothly with micro sd card. Unfortunately Note 20 Ultra 128Gb storage not enought.

You should have plenty of room for a normal load...
You don't want to run apps from the SD card vs internal memory.
The bridge and memory of the SD card are much slower than internal.
It's purpose is as a data drive.
You want the SD card isolated from internal memory.
Move all critical data to the data drive. Put everything up need to do a factory reload here as well including copies of apps and backup settings. Back this drive up redundantly to at least 2 hdds that are physically and electronically isolated from each other!
The OS, apps, the temporary photo and download folders go on the internal memory. Keep this drive as small as possible.
Use a V30 or higher card, vids run fine from it. The Lexar .5tb V30 goes for about $75 and it's good to go out of the box. Format in phone before use.
This is how my 10+ is set up. Using about 60gb of the internal and 340gb of the card. It runs fast and stable.
I got the A22 5G and I like it apart from one huge issue.
I encrypted my sd card (256 GB) and transfer rates are unbearably slow.
If I copy a 2 GB file from the internal storage to the SD card it will start ok (20 MB/s) but this is likely only the cache.
Soon it slows down to ultimately 10-50 kB/s which is unusable, copying was not finished after 15 min.
When I decrypt the card again everything is as fast as expected. I checked the SD card on another phone, no speed problems.
Back into the Samsung and encrypted it is unusably slow again.
Did anybody have a similar issue?
I returned the phone.
In case somebody else runs into this issue I'm afraid I could not determine the cause.
I tried adopting the SD card as internal storage via adp commands but Samsung has even blocked this now.
One can partition the SD card as internal storage still but it is not possible to trigger the migration.
This means any normal application will still only see the internal phone storage and not the sd card's.
Clear system cache.
Low level format the card, then format it again with the phone.
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.

Yay! Nothing like success!
Congratulations on your 1.5tb dual drive handheld PC

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
