I bought an A3 2017 UK market (A320FL) BTU, for my wife, it came with nougat out of the box, did updated to XXS2BRAA OTA straight away

Then I did root it, TWRP and SuperSU, all went fine no probs at all.

Then I added the zip file for adopted memory, and is working fine, received the message that the card inserted was slow, so I will get a UHS-I card, just ordered one from amazon should be here tomorrow.

Do not see or feel lag at all, so all is working fine.

Could you please tell me if it's possible for a stock 2017 A3 to be modified to use adoptable storage? It's not clear to me if the corrupt SD card option is supposed to work for a stock phone or only one that's running a custom ROM / recovery console. I've tried using the adb option listed elsewhere but that did nothing.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] wegiwegi:
Ir will work on stock ROM, but you will have to get twrp in order to flash the adootable storage zip file, for the SD card to work, just delete the partition on the SD card on your computer, then when inserted on the phone, it will tell you to format the SD card and then you can choose to make it adoptable after that.

Banking Software

In trying to get this to work I went a bit overboard and rooted the phone (I hit just about every error and guard possible) so now the banking apps won't run as they check for jail broken phones in some way. If I restore the standard firmware and just do the bare minimum detailed in the original post, do you think the bank apps would still run and not complain about the phone running a customer recovery?

What are the downsides of tripping Knox?

Been away from the modding scene, I’m on iPhone now but my mum has a A3 2017 and she desperately needs more storage. And seeing as Samsung have disables adoptable storage, it leaves little option but to root and enable it.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] sk8223:
God, this pisses the f*** out of me. Why the hell did they disable the adb method (list-disks) for the A5? Why does stupid Samsung care so much. Do they realize how much space apps take these days? I don't want to root because I don't want to play the Magisk cat-and-mouse game, and I already have my Redmi Note 4 for root stuff. Such a dumb decision. All of my game apps alone take more than 4 gigs of space and they detect root.

Funny that it worked perfectly for my dad's G6 and the S7 but it doesn't work on some low-end Samsung phone. Figures. Cheaper phones really do get fewer features. /s

EDIT: whoops. So there's an additional command called "sm set-force-adoptable true". I redid everything but I couldn't find the option to set the SD card as internal storage (or combine the two) in Settings.

Instead, I enabled Dev options and enabled forced external storage. Thankfully it works! I can move any app I want to external storage now.

Hello

the main drawback of Galaxy A3 is storage

So I have bought a SanDisk Extreme PRO 128 Go (U3, V30, A1)

I planned to use 50% for adoptable storage and 50% for other partition for pictures (mainly to be able to read the pictures on other devices, not only PC)

I have installed the patch, after I use the tool "Auto-formatting SDCard" and I reinstall the SD card

But I think that It dosn't work.

It think that adoptable storage is here, but all the card was used

I am on Android 7

How did you do it? I've currently bricked my OH A3 hoping a full Oreo wipe will solve it, 2 nervous hours until it's downloaded though.

I followed the instructions, it told me I had to wipe the device and then won't reboot.

EDIT: Phone back up and running. I'm just not convinced adoptable storage is running as expected. The overall amount of RAM on the device is the same as before, apps are listed as being either internal storage or external storage separately, so expecting will still run out of space as doesn't seem any better than having it as an external storage device?

I have flashed the last FW for my phone ( A320FLXXU2CRE3 ) via ODIN,

I have installed root and adoptable_storage_enabler_ashyx in the TWRP

Turned on the phone and put SD card (32gb a1) to the phone. In the popup, I set internal storage.

It looks good but, in the Device maintenance -> Storage I still see 16Gb, but when I open tree dots and storage settings, I see "... used out of 45.5GB". When I open sd card, I see there two application but none of them are working. And when I want to open these applications in the settings -> Storage, the settings crashed.

I am not able to use all of the storage. When I use e.g. 15gb, I am not able to download any application which has more than 1gb.

Well, it seems that this thread would really benefit from some actual replies to the many questions accumulated over time. People are asking whether "adoptable storage" will work with the newer Android OS, for instance, or different ROMS. Various issues are listed - again with no reply.

I personally am wondering about the potential problems if I try the method described with Oreo. Apart from wlanowski's short post ("it worked"), there is no info at all and this prevents me from giving it a try.

Pretty bothering as I still find this phone perfectly ok...

I got it to work on my A3, running stock Oreo! 🎉

I had a problem flashing the zip because TWRP was unable to mount internal storage and it gave me lots of errors. If I just flashed it anyway, the phone would say security check failed and refuse to boot. I had to completely wipe it and reflash the rom to get it working again.

To actually solve the problem, I had to make sure I don't let the phone boot after flashing the stock rom with Odin and then immediately flash TWRP after, then boot straight into TWRP and flash the zip. Now when I booted the phone it opened the setup wizard in Hungarian (first indication that something had changed...). And when I put in the SD card (formatted as NTFS so it would prompt me to reformat) it showed me the option to format as internal storage. 😃(y)

Under settings it now shows something like 5GB of 64GB free, which is a little concerning, but in Google Files it shows 53 GB free so let's hope it holds up...

@superseppel13

So you basically

flashed TWRP to your phone,

booted into TWRP,

flashed the patch

and it worked for you?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] superseppel13:
I also flashed the latest stock ROM (i.e. I did a complete wipe of the phone). The trick was to flash the patch before Android boots for the first time. Because the first time it boots, the system partition gets encrypted and that prevents the patch from working.

So what I did is:

Flash stock ROM (don't let it boot!)

Flash TWRP

Boot into TWRP

Flash the patch

That worked, in principle.

However, I can now report that it didn't really fix the problem because it turns out that Android, even with adoptable storage, refuses to install apps on the SD card unless the developer designates them as installable on SD, which almost none do. So in the end, the memory still fills up and the phone refuses to install any new apps (or update existing ones).

It's very sad but there really doesn't seem to be an effective way of extending the memory of an old but otherwise perfectly functional phone... :(

Guys

Happy to say I found a solution to this! Even though many apps do not let you move them to the SD card (beacuse the developers of these apps have decided so), there is an option to override this - and what's best, it is even in the stock ROM without any need to flash anything and potentially lose banking etc.

You just need to activate the developer mode, so that developer settings appear. Then you scroll down and at the Apps section, you should see and option to force permission for apps on external storage (something like that, my phone is in Czech language so I am just assumimg how it could look in English).

That's all - now all apps can be moved to SD! So excited about this - let me know, if it worked for you too. :)

I am using this method. Just flash the ZIP file which I attached here in Recovery and then you will be able to format SD card as Internal Storage.

*** If it is not working, you must need to FORMAT DATA to delete the encryption, so before of that - make a backup of all your files ***

I tested it on Android 13 and it is working perfectly.

Then you can use for example an app: APP2SD (https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd) from Google Play to move apps to adopted storage (SD CARD)

Hi! May I ask if you have a A3 2017 (A320) and how you installed android 13? Is it as fast and fluid as the latest stock ROM (Oreo)?

Here is a feedback of my personal successful adoptable storage for a galaxy A320FL with a 128GB microSDXC card (Kingston Canvas Go! Plus, U3, UHS-I, A2). For the people asking, it is normal that the default Samsung storage app is confused about the available space. But it does work.

To fix the "verification failed", I had to similarly flash a no-verity-opt-encrypt. See here:
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] dandreye:
@maxanthem:

Could you please describe the process you followed step by step? I have exact same phone running exact same stock ROM (just not the most recent build as I had rooted it and flashed TWRP Recovery a long time ago) and - to the best of my knowledge - no encryption due to "no verity" flashed just before its 1st start. I also have a similar microSDXC card ( Samsung Evo+ 128GB U3/V30 UHS-I A2). Flashing the zip went seemingly fine. Minidisk Partition Wizard 12 shows Disk 2 GPT 119.38GB with entire space unallocated, as per the OP's instructions. And still I never get that choice between Internal and Portable with this card for some reason. I do get it all with a 2GB microSD card that was external storage in this phone before though. Wondering in particular if your card is GPT or MBR.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] maxanthem:
@dandreye , Dear A320FL fellow!

Before entering the detail of how I did it, can you tell me two things?

A. Can you access the 128GB micro SD card from the phone (move data or app in the "normal" way as without adoptable storage)? Does the phone detect it?

B. The author (OP) indicated that it might be required to artificially

corrupt

the micro SD card to make the phone query to format it and then use as internal storage. It wasn't required in my case as the notification appeared, but did try it? Apparently you tried to delete all the partitions (all unallocated), but have you tried the second option: format it using the phone and stop with the back button before it finishes?

Now here is what I did (there might some unnecessary extra steps I guess):

0. The phone has the latest stock ROM, not rooted, without any extra (no TWRP for instance).

1. Authorize OEM unlock

2. Download mode → install TWRP (I had a linux computer, so I used Heimdall instead of Odin and payed attention to add a no-reboot option in the command line. The first attempt with reboot failed, and the phone restored the original recovery mode)

3. I tried to flash the adoptable storage enabler zip with TWRP, but then the phone didn't want to boot because of the "verification failed". (Maybe it's because I didn't wipe Dalvik cache after flashing the zip?)

4. I tried to wipe the whole data of the phone through TWRP, but the "verification failed" remained. That was before I found the post from Shameera_N.

5. I applied their fix:

5.1. In TWRP: wipe data (so that was the second time for me)

5.2. Reboot to recovery

5.3. Flash the no-verity-encrypt file

5.4. Reboot to recovery

5.5. Flash the adoptable storage enabler (so, second attempt, here)

5.6. Wipe Dalvik, Cache directly after

6. When I finally rebooted on the phone, I went through the first initialization / setup / google register (the data was wiped, remember).

7. I inserted the newly bought micro SD card (nothing had been written on it). The phone asked me if I want to use it as internal storage, and I said yes.

I assume that you followed step 5., in particular flashing the adoptable storage enabler zip at sub-step 5.5., in this case I case suggest to focus on corrupting the micro SD card. If you can see the micro SD card on the phone, do as I mentioned before (start to format via the phone and stop before it ends to corrupt it). If you cannot, create a partition / format it back on you computer and try again. (Possibly with the interrupted formatting trick.)

Tell me how it works out for you,

Have a good week!
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] dandreye:
@maxanthem:

Thanks a lot for a detailed reply. The problem is my phone won't see the card no matter what, so there's nothing to try formatting. It's definitely not seeing it now that it's GPT type, and IIRC it wasn't seeing it either when it was still MBR type w/o partitions. I can't remember at which point and how exactly it got converted from MBR to GPT after doing too many things to it w/o making any notes: perhaps it happened in my other phone SM-A310F with Android 7 that I also tried using it in. I could try restoring it back to its original state (MBR type with a single exFAT partition): perhaps the phone will see it at least that way. Btw I suppose yours also came with a single partition and it worked as is for you w/o the need to delete that partition?

So steps 5.1-5.3 had been done a few years ago (hence no encryption since then) and as a result I only had to do steps 5.4-5.5 this time, and "verification failed" never showed up. I didn't do step 5.6 though. If I do it now I suppose my accounts and data won't get hurt, right?

In fact my final goal is 2 partitions on the card: one for internal storage extension and the other for external storage (music etc). I did a similar trick with Orange San Francisco phone running Android 2.3 a decade ago and it worked a treat there. Remembering that I had to manually partition the card as desired back then I also tried doing the same this time (using Minitool Partition Wizard) but still no luck. Just before that I tried this but the tool returns an error, and an attempt to do its job manually using "sm partition ..." just returns the command prompt in <1s w/o any errors and w/o doing anything whatsoever with the card.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] maxanthem:
@dandreye

From the fact that you said that the adoptable storage option was available with the other 2GB microSD card, I assume that nothing is wrong with your phone, but only your new microSD card.

(I am not an expert and don't hold me responsible, but I think that the Dalvik just a cache so ok to wipe, but it shouldn't change anything to you if the problem comes from the microSD card).

I didn't check the partition of my microSD card after I bought it, but I can only recommend reformatting yours. Maybe even a basic format tool from your computer. Then try the adoptable storage on it and if the option is not detected, try to format it with the phone and abort (corruption trick).
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] dandreye:
@maxanthem:

Following card restoration to its original state I got the prompt indeed, and so selected internal and proceeded with its formatting and just didn't export any data on it yet. Are there any signs of extra internal storage anywhere to be found? E.g. there are no changes in DiskInfo and in Device Maintenance > Storage.

Update: the partitioning is looking somewhat weird as can be seen in the screenshot attached. Partitioning type got changed from MBR to GPT again, so now we know it's part of the process of using it as internal.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] maxanthem:
@dandreye

Ah! So this is good news: you managed to get the prompt to use it as internal storage right?

The "Device Maintenance > Storage" also acts weird for me, but I do get to see something like 119GB for internal (and supposedly mostly used but I know it's not true), and that is how I know it worked.

I guess that if you get to the prompt and accepted to use the microSD card as internal storage, nothing else is to be done. Just use your phone normally and consider that you have no control on the external storage => by definition all is now internal.

So I don't really know how you would be able to use 2 partitions on the microSD card, but I am interested if you manage.

The following website confirms that adoptable storage is partitioned as GPT, it also provides a test command to check that the adoptable storage is working (but I don't really know where to run the command though): https://source.android.com/docs/core/storage/adoptable
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] dandreye:
@maxanthem:

Yep, and took advantage of it right away. Interestingly an existing partition didn't hurt - it's the lack thereof that did (in my case at least), despite the OP's instruction to delete all partitions on it.

I don't... but perhaps I'll see it once I start actually using it. Meanwhile I've just found the first sign of it present - the very last entry in the following output from the phone's terminal window:

Spoiler content hidden.

Looks like those commands need this to work: https://source.android.com/docs/compatibility/cts/run

Probably easier just to try exporting something onto that card for those of us who are not that much into this system stuff )

Would be ideal to have the OP himself comment on whether it's possible at all if he's seeing this... I guess manually partitioning the card with 2 partitions and mounting one of them in a similar fashion somehow would do the trick. Probably that's how it was done for Orange San Francisco... here.

Update: a random app (I tried Zoom) just got successfully installed onto the (single-partitioned) card, so it's working fine.
