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.

So I've been having issues with my apps if I put them on the SD card. if I put them on the SD card they get horrible slow and laggy. Facebook for example can hang for minutes before loading what I clicked giving messages that the app is hanging and if I want to close it.
currently I'm running the Concept firmware , but even with that the Z3 runs out of internal memory very fast. and with some apps (groove) not allowing you to store data on the SD card, it gets a lot worse, making them unusable. After I installed the concept firmware I did reinsert the SD card and chose to format it so it's supposed to be an extension of the internal memory but it also doesn't seem to really work :/
Anyway right now I believe I'm running a sandisk card of some type, probably C10 if I remember right(can't really remove it right now). Is it the type/class of card that makes it work so slow on the phone ? is there some other preferred type and class of SD card that doesn't cause this serious app lag, and is there a way to then set it up so that apps that store large data and don't have a setting for SD card will still store on SD or to unify internal and SD storage as one ?
I believe it's the card. even the class 10 cards are horribly slow for use as system storage. install a sdcard speed test app and test both internal storage vs sdcard read/write speeds. And you will be shocked.
I Use Samsung pro 64gb card. And I was able to use it as system storage on concept rom. It has 90/80 read/write (*rated) speeds. And it works fine on my z3.
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 am switching to a new phone as my old one no longer seems to recognise my SD card. The SD card itself appears to be fine, as it functions perfectly well in my other phone and on my PC.
When using the SD card with my old phone, I transferred a lot of apps (as many as I could) to the SD card, so I guess that data is still there physically on the SD card. They do not, however, show up as apps when the SD card is inserted into my new phone.
So, what I want to know is, if I reinstall the apps on my new phone from Google Play and transfer them to the SD card again (to save internal memory space), will they overwrite the ones already on the SD card, or will the presence of those apps be duplicated on my SD card (i.e. one newly installed functional app, and one older version that is no longer accessible on the new phone)?
If the latter, can I delete the old app files directly from my SD card to make way for the new ones, or will this cause issues?
Finally, is this all just asking for trouble, and should I just backup anything I need to and format the card before using it in the new phone?
Many thanks!

(for your reference, I am transferring a 64gb micro SD card from an LG G3 to a Moto G5).
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
