How to set the memory card as internal 'adoptable' storage on Galaxy S7 and S7 edge (no root)

How to set the memory card as internal 'adoptable' storage on Galaxy S7 and S7 edge (no root)
The Adoptable Storage feature of Marshmallow has the ability to merge the internal memory of a phone with the external storage in the form of a microSD card (if the device has such a memory slot), and treat the resulting cumulative memory as a one total partition. In theory, this would prevent user confusion as to how much exactly free space they have in total on the phone, instead of trying to calculate microSD storage and internal storage separately, or asking themselves what are these things in general.

Now, here comes the surprise - both the Galaxy S7 and Galaxy S7 edge don't support this Adoptable Storage feature, despite shipping with Marshmallow on board. Thus, they'll treat the microSD card as a separate entity, instead of lumping it together with the internal memory in the storage menu. Here is Samsung's argumentation behind this decision: "Samsung decided not to use the Android Marshmallow “adoptable storage” model. We believe that our users want a microSD card to transfer files between their phone and other devices (laptop, tablet, etc), especially the photos and videos they shoot with the camera." 

Still, if you want Adoptable Storage on your S7 or S7 edge without rooting them to trip KNOX, and don't mind typing a few lines in a command prompt, geek-fu style, here's what you need to do:

1. Needless to say, first backup all data you have on the microSD card. Go to Settings>About, and tap 5 times on the build number to enable USB debugging on your Galaxy S7 or S7 edge

3. Connect your phone with the USB debugging option active, and in the command prompt on your computer, type adb shell

4. Key in sm list-disks, so that the phone can display the particular disk ID of your card;

5. If you want to use only part of the memory card for Adoptable Storage, and the rest for shuttling files back and forth, you can split them in half with the command sm partition disk:179:160 mixed 50, where 179:160 is whatever disk ID was displayed in the previous step.

6. It will be less problematic to use the whole card in Adoptable Storage mode, though, so you can simply type in sm partition disk:179:160, or whatever your disk ID numbers are, and then wait for the lengthy merging process to finish;

7. That's it, when you go to Settings>Storage now, you won't be seeing the SD card option, but all storage will be lumped together instead, though the total amount might not be present in the system app, so you'd have to install a third party file browser from the Play Store or a storage widget to keep an eye on it. Bear in mind that this will format your card, so make sure you have everything backed up to restore in this new common storage beforehand.

Why would anyone want to do that? You can already store apps on SD card on S7, without adoptable storage. And that also allows you to use the card elsewhere.

If you go for adoptable storage, you have absolutely no control over where an app goes. So a performance hungry app may be stored on microSD, whereas you may want it to be stored on the fast flash storage. Also important to mention that the device is encrypted. So making SD card as internal may further slow things down.

This little news doesn't cover up the hypocrisy of their articles and reviews. From crediting features from different rivals that Samsung implements in their device, to ALWAYS one rival, apple:


Yet not writing a single article pointing out the dozens of features that single rival has copied:



To mentioning cons in non-apple device reviews, yet ignoring those same cons in apple device reviews even though they 100% apply.

To inconsistency in product reviews. Like their con for the S6 was due to it lacking a MicroSD card slot, so they gave it a 9.3. Then S7 fixes that and improves on many other things, they go and give it a 9.

A little positive article ain't gonna fix all of that anytime soon. They need to end their hypocrisy and double standards.

Granted there should be some diligence from the top, but there are a whole bunch of different writers you know? I simply don't believe it's a carefully planned agenda.

You think there aren't fans of other phones makers that don't always get a fair shake? Samsung is huge in scale and popularity, there are going to be unflattering articles. And every time one of those articles pops up, "iphonearena". Skins so damn thin it's amazing they can type at all.

I personally don't put so much faith into the review numbers to begin with so I'm not bent out of shape for a bit of numeric inconsistency. Though I might guess a phone getting reviewed a year latter might not have different expectations. ¯\_(ツ)_/¯

For what it's worth:







Just sayin, a quick look shows samsung gets decent love too.

Chaos the features dont work correctly using it this way they said it you need third party app to see the space and you dont see the options on the setting.

So its not thats usefull they should have left it fully open so we can choose if we want to use or not.

Then when customers have problems with the speed of the phone, as main parts of the phone is using the sd card, Samsung as big problem, at this time it's supper fast, also all normal sd card info in preloaded Into the ram to speed it up, it's why all the images just also load on the phone from sd card, unlike before with the s5

tyrion, the not so wise

You can't use the sdcard for applications without this, the ONLY option you have window this is the old "apps to sd" hasn't been been reliable for years and usually fails with large applications.

If you want decent performance users will have to buy a high quality sdcard card, it won't match the internal performance but it's not that bad.

It's all about choice.

Yes, the apps to SD fails for large apps. But large apps shouldn't be moved to SD card at all, since they require huge I/O operations and the slowdown will be real. Even high end SD cards barely reach 1/10 speed in random I/O compared to flash storage.

Users don't want choice. They mess up and then blame the manufacturer for their own stupidity, leading to bad reviews of the product and bad publicity. That's the reason why apple products get so popular. As the 99% 'dumb' crowd gets no issues with them. However, those people don't know how to get around in settings on android and hence get poor experience.

Either way, doing this doesn't give you choice. It's a one time thing and if your SD card fails, you're done for. Also you can't 'choose' whether to install the app on SD or internal.

A good solution would be a better working 'move to SD' option. But right now, not enabling adoptable storage seems to be the better solution.

I agree with you, it's a total pain to use, it's unreliable and prone to failure.

However when we have limited storage users have no choice but to go down this road.

It's Samsung's fault for not giving us more internal storage.

Real racing 3 on my sd card no lag or slowdown.
Some ppl need to test stuff before talking for nothing.

Giving the choice in developper option would been a minimal. Majority of non tech ppl dont even know how to access it.

As for SD card fail my SD is cover by a lifetime warranty and in nearly 10 years working in the industry i never saw a high end sd card fail only crappy one.

a better working move to sd already exist its called SD card adoption. You get the best of both world as you can force an app back to real onboard memory if you need.

Stop searching excuses.

Yep removing the choice then having to use command line and get half the features is simply wrong.

And yes thats what we tested in store nearly half the app did not want to go on SD on the S7 where on my moto x play with adopted memory i was able to put at least 90% of them on the SD.

Hm, I now 100% are up on you being full of it, "in the store only half the app did not move over," hahahahahhahahahahahhahahahah
It's not the s4 and s5
Ion the s7" if the App can be moved to sd card, then it moves all the data and not part of it like back in the days of s5 and s4
(I think this is part of android 6)

So this way you can put things you need on the sd card, like I moved all Spotify music data there,
Also in this mode, Samsung preloads the data into ram, so it works faster than from the s5 and s4 or if it was using adopted way

Exactly! I really don't understand what's the fuss for this "Adoptable Storage". Samsung has had the "Move to SD Card" function in TouchWiz. Even when google was abandoning SD cards support in Android, they provided a hack to do this.

That not the case, now, most of the apps can be moved and they moved in full as its now supported in. Android unlike before where Samsung was having to hack it, it's also now reliable as it transfer the full app and Samsung also preloads it to the ram when it used

I guess yes. But it doesn't give you performance benefit, unlike nexus devices. So I suggest to keep it encrypted.

Unencrypte is not a word. The word you're looking for is called decrypt.

Thank you....you are the wise one....haha.....i was just curious if there was a performance difference. ....if not then yes keep it encrypted. ....one other question. ....if it was decrypted would it still reformat the sd and make unusable in other devices or is the formatting a different issue

Honestly no idea regarding that. You should ask that to a person who owns the device. But I'm pretty sure you can use the SD card on other devices too, as Samsung said that in their statement.

20. Note4user (Posts: 1; Member since: 11 Mar 2016)

I'll tell you exactly why you'd want to do this. I have GearVR Innovator Edition on Note 4 32GB and a 128GB SD card. Currently, I have 2.3GB available out of that 32 and that doesn't leave enough room for additional VR apps. Those can easily be > 500MB and >1GB if there is 360 degree video. My SD card has 98GB available and zero VR apps will move to SD.

Video can sustain >12Mbit/sec - current phone providers absolutely cannot meet that requirement, so it's download-only if you want to see something without being tethered to wifi.

Adoptable storage is a must without a 128GB phone available.

Well we tested the S7 vs the moto x play i have in store today.

I can put much more app on my adopted SD card than the S7 ( this mean with the S7 not all app can do it but with my moto x play all app can )

Dont lie about the adopted sd card features you obviously did not test it.
If you go to app list you still have the choice to force the app on the onboard memory or on the SD.

As for slowdown there is no slowdown in fact i forced the system to put all my apps and games on the adopted SD storage and its work perfectly well.

I dont understand those Apologist thats lie and say crap whitout knowing the reality.

posted on 11 Mar 2016, 12:14

42. tyrionTheWise (unregistered)

I don't believe you on no slowdown. Maybe because you're used to slow memory of your moto X. I have had UHS SD cards fail and the damage is real. Just because you didn't had a fail doesn't mean it doesn't happen.

making SD card as part of internal storage is like doing a RAID0. You are literally doubling the risk of failure. Actually more than double as SD cards fail a lot more than NAND flash.

I have a few apps moved to SD on my S4 and they take longer to load. Obviously performance won't be affected as the game/app moves to the DRAM after loading. But loading times are affected.

Also what will you do when you have to do a factory reset. All the data in phone as well as SD card will be wiped out.

There's a reason people partition their drives on PC. Sd card is for storing media, not apps.

You're totally right and Samsung made the correct decision. Is take the separate any day. Especially for rooting. A SD card can literally sane your phone if you wipe your internal and don't have an OS present. And for nandroids...I'll take external storage separate Any and everyday

This is gonna cause more issues than not, SD-cards are prone to failure and will drag the phone down with it when it fails. Then people will be moaning phone is overheating, battery life problems, lags etc. It's better to separate the function of the lightning fast ufs storage and slow SD-cards. I really wonder why people wanna put Apps on SD-cards anyways, it's slow as fu*k and eats more battery life.

Stop lying and test it before speaking.

Never had a single SD card fail on me in 10 year ( i only use high end one )
The features double check to make sure your card is high end and wont turn on if not ( test it before speaking! )

No over heat or slowdown all my apps and games are on my sd part of my adopted storage.

So sorry but stop apologizing for Samsung.

Doesn't look like the move to SD card option is there any more on my S5. :(

I don't even know if the adopt hack will work on the S5, but I've decided not to try for the sole reason of the potential of an SD card failure. I haven't had one fail, as such, but I have had a couple occasions where the phone suddenly forgot it was there. Once on my old S3 and once on my S5. Sure, it's a very low "failure" rate, but to me it's not worth the risk.

Samsung Galaxy S7 will let you Move Apps to SD


posted on 24 May 2016, 18:30

50. DialTonez (Posts: 1; Member since: 24 May 2016)

Yes, it will allow you to move apps and has been since the TouchWiz version that came with the S5. However, this one is SERIOUSLY flawed. Moving half or less of an application to the SD card does not serve my needs in the least. Changing the process from a simple one-click to this 3-click to move version is annoying. And when an application updates it installs the update back to internal memory which then makes it pointless to move apps to the SD card as I wish to spend my time actually using my phone, not moving something back after I have already told the OS where I wanted it.

So I either run the risk of losing data (which, if one backs up their device to the cloud using any number of apps that are on the market today, risk of losing your data is minimal), or I run the risk of unwittingly running out of internal memory because Samsung doesn't know how to apply app updates without moving them back to internal memory.

Hmmm.... I think I'd rather perform the hack than deal with the flaws in the OS. And as far as people saying that your apps will take a performance hit when you move them to the SD card, they're right...but what they fail to mention is that even with the performance hit, the app will still most likely be faster than your last generation phone that you gave up to get the new hotness. IJS.

Great hack to add what Samsung should have included from the start!

Can you believe them only giving 32GB of storage on their 2016 flagship phones, probably less than 25GB actually usable?

Move to SD is a crappy and tedious experience and most apps don't support it.

I haven't noticed any slowdown with adoptable storage, even on my midrange Motorola Moto X Play, so some ppl need to stop writing complete trash and generalising.

I tried downloading the "quick" package, told it to install system wide, and installed the drivers. Connected my Samsung tablet, type adb shell, and got "device not found". Of course, I just thought I should double-check it actually has Marshmallow on it.

Also, I have been reading above that you can move apps to the SD card, True, But, there was an app I moved, and I COULD NOT install the update. Couldn't figure out why. Then I moved it back onto the phone, and it updated fine. So, while you can move apps to the SD card, that doesn't mean everything will work properly. Granted, that was only one app ( Sky Map, to be specific ).

I need some help or advise. I tried to follow the MoDaCo guide to achive "adoptable storage" on my Galaxy On5 to format my sdcard for either, private or mixed.

I got all the correct drivers and ADB installed and any ADB command I try works, except if I do one of these two :

sm partition disk:179:160 private
sm partition disk:179:160 mixed 50 ( my disk name is different from theses examples )

None of these ADB shell commands work or do anything to the sdcard. Anybody has an idea on why these commands don't work ? I tried it with a 128GB Sandisk Ultra card as well as with a Samsung EVO 64GB.

Also, trying to format the sdcards via ADB in TWRP recovery don't do anything..... It shows the disk via the list-disk command, but no format.

Any ideas ? Any suggestions ?

Thx a bunch.......
