Clarification for SD card issues on kitkat 4.4.2

To save some people time in searching and asking the same question I had (and for 4.4.2 I think there will be plenty...):
I had severe issues using a brand new SD card in a brand new unrooted Galaxy S5. However, I now found through test that it was not the card.
I tried many things, formatting on my computer, formatting on another phone, etc etc. Nothing worked. I then tried to use the card on other devices, which worked fine! I then tried other cards, none of them seemed to work.
So I thought the S5 was defective. I did some searching online, and found that it actually is not defective. This is a feature of kitkat 4.4.2!
The card is perfectly usable, but under very restrict situations.
For example, reading is perfectly possible, but writing is controlled by kitkat. I found through some websites that Samsung decided to beef up security and at the same time make the use of external storage more clean.
Previously you could use any file browser to manage any file son any external storage, like an SD card. Although this gave great freedom, Samsung also seemed to believe that it is a source of security risk where rogue apps could read/write to folders they didn't create. They also seemed to believe this made management of files on external storage messy. To control this Samsung now allows properly installed apps to generate folders only in internal memory, and those same apps can only access folders they themselves created. The exception to this are factory standard default apps that come preinstalled on the device.
So my mistake was to use ASTRO file manager to move around a file. Once I read the issue online, I tried the same action with Samsung's pre-installed file manager, and to my surprise the file did transfer to the SD card!
To further clarify, I suspect this "feature" is limited to write activities. For example, backup to SD apps will fail to write apps to SD. Similarly, Airdroid cannot copy files from your desktop to the SD card, only to their own folder (and thus you need Samsungs file manager to move those files to the SD card).
What's interesting about this however, is that READ access seems to still be possible. ASTRO file manager can still read files from directories other apps made. Adobe reader can still read files on all kinds of folders.
The criminal spy app can still read and copy your banking files from your bank directory to its own directory for transfer to the criminal mind who will then plunder your account. So no, the security issue Samsung wanted to address has not been addressed.
What is my opinion about this? Well, I think Samsung made a nice attempt to improve security. However, they completely failed to address the biggest security risk, which isn't write access, but read access. And at the same time made it very painful and difficult to store large numbers of music, video and document files to the SD card. Because now you will either need to plug in your memory card into your computer, or move all those files via internal memory to the external SD card using Samsungs file manager, which of course takes much more time.
More info on the feature can be found here:

http://support.solidexplorer.pl/responses/kit-kat-442-issue
And here:
http://developer.samsung.com/forum/...Lines=15&startId=zzzzz~&startPage=2&curPage=4
We could all ask Samsung to revert this "feature", but chances that they will, are remote since there are ways around this problem.
Of course, people who use many many apps/games will be out of luck, as they will be restricted to 16/32 GB.
Note to moderators: Can we make this a sticky for kitkat 4.4.2?

Root and you'll be able to R/W on the ext-SD card and try this app SDFix
Samsung has nothing to do with it... It's an Google's android policy.

So, the links I provided make that same statement. I.e. I'm aware of possible fixes. However, I bought my phone in Singapore so I could have a reliable unhacked, unrooted, unmodified phone. Others might also want original phones and not root their phone until their warranty runs out.
This was not my point though. My point was to provide some info that could be turned into a sticky so it is easier for people to find what could cause their memory card issues.
I still hope the original post will help others troubleshoot their memory card issues with their s5.

obb files to external

I did search and with the google searches I've done, can't really figure it out so thought might ask here.
When I moved applications to external sd card, i didn't realize it didn't move the application data itself (inside obb folder), which is in the android device's internal memory. So basically, I have the application (i guess equivalent to .exe for windows) on the external sd card, but the beef of it (the applicatin's data) is still on the internal memory and using up the device's memory....how can I move the data (obb folder) to external, remove it from interernal to free up space, and have it boot up / work on the android device?
i'm not advance geek so need a dummy explination

You didn't provide details of how you moved the app or even what app we are talking about. So it's impossible to give targeted advice. Which is unfortunate since you want a dumbed down, simple answer. Which can't be done without knowing those crucial details.
You can use one of the Play store apps to move the app. I'm sure that some of them would move the app data as well. Or change the app data path (folder) in the app's settings. Or reinstall the app. Or alias the current internal data location to the external card with a symbolic link. Or any number of other ways.
The simplest options there would be trying some of the Play store apps that assist in moving programs to the external data card. And if that doesn't work for some reason, then reinstall your app.
Good luck.

Only thing I've done was root it then moved the application (move to sd card) via settings >> Application Manager. i want to do it for all apps but it's mainly due to games taking up lots of space. Reinstallng won't help cause everything that's obb just direct itsself to the internal storage, nothing i installed even gives me the option to install data into external, just only has a install button and it installs to internal memory

I'm not going to sort all of that out. It can be done if you look into the details.
The best advice that I can offer is to consider installing a custom S5 ROM like Phoenix. It has a setup option to swap the SD cards. That would mean that all of your apps that automatically install and live on the internal memory.. would actually end up on the external card. And it works perfectly.. because the apps think that they are on the internal card even though they aren't.
The source script could also be applied to your existing configuration, but doing so would not fit inside your stipulation for a simple answer.

fffft, one question here: Would it be possible to format the whole external SD card with ext4? So it would be quite simple to copy such files manually within a shell and set a softlink to the moved files? I don't understand why android stays with that fat drived file systems were softlinks are not working. Is there any reason for? So all data2SD apps have to work with specific *mounts*. I can't believe that this is fast and stable.

That won't work unless you do a lot more prep work. The file system isn't invisible, the OS would have to interact differently with ext4 than ExFAT. The OS would balk the first time it tried to follow a symbolic link and didn't find the ExFAT structure it expects.
To make that work, you'd need to mount the card yourself, manage permissions and hide the file attributes i.e. permissions from the void manager and other housekeeping tasks. Android expects to find a case insensitive and permissionless FS. Otherwise, void will report errors to the volume manager and the OS won't recognize your card. All of which is to say that this is a more distant outlier to the requirement for a simple solution. So you'd be generating fatal errors the first time the OS tried to follow a symbolic link to your ext4 files.
So yeah you can shoehorn an ext4 card into the system with enough work. But it isn't as simple as you believe. So back to my suggestions that the OP either install a custom ROM that does what he wants or that he looks at the script that I linked him to. Or perhaps migrate to CM 11, where native support for ext4 and NTFS have been added.

Large games on sd card

Hello,
I was searching for a way to put large games like (asphalt 8, nova3, and any other games) on sd card on my rooted samsung galaxy s4 because the internal storage is very low and about to be full.
First i tried to use the file manager i have sent the odd file and the apk(which in the data folder) but the game didn't work, it was searching for required files and asked to download them.
Then i tried many apps which need root acces on my device to send the games on sd card but i got the same problem...
Is there are any way to send the game on sd card and make it work there?
Thanks.

try app2sd...it is on play store ?

I have already tried it but it send the apk file only i want app or any way to send the apk and the odd to the sd card and make it work there.

This depends on what rom you're using.
You could try Folder Mount

Actually all these apps aren't useful i can already use any file manager to send the game files to the sd card but the problem is when i add the game to sd card when i open the game it dont find the game's files.
And about which rom am i using i didn't get it and how to know my rom?

I use the xposed module Obb2SD, so all my games are moved to SD card then the Obb files are also moved onto the SD card.
I am using a custom Rom.

If you are using the stock samsung rom then you just have to go to Manage apps and find the game you want to move and the press "Move to sd card".
Moving the apps manually will not work.
Folder Mount will move the app data to the sd card and trick the system into thinking it's on the internal storage.

I have just used folder mount by sending the game files (the folder in the data and its folder in the odd) but the game won't find their files

Did you get the phone new? Did you flash any custom rom on it or is it the stock samsung firmware that comes with the phone?

The only thing i have done with my phoned is rooting it with a custom recovery, there is no any custom roms im just using just the stock rom.

Then the rom should have the option to move apps to sd.
I know that my stock 4.4.2 samsung firmware had that option.
Go to settings > apps > downloaded, and tap any app you want to move. There should be an option "move to sd card" or something like that.

Set external SD card to default install location [HELP]

Hi, my problem is with the phone of my girlfriend. Now have external 64GB SD, because internal storage is full. I used Android SDK and all the instructions for set default storage for install APP the new SD Card, you know, with the command adb shell pm set-install-location 2. And no error, i try get-install-location and report 2. But googe play only try to install in the internal storage.
I think the problem is with the system of the emulated storaged or something, but i tried many APP, many solutions, and i cant fix this, i search in google and others locations, have 30 tabs in firefox open with information, but i cant found the solution for this

I tried dismounting and mounting the SD, touching the vold.stab file, but do not get any results.
Can anybody help me?

Go back to stock, upgrade to 6.0.1. Then see if this helps-
http://www.modaco.com/news/android/...e-adoptable-storage-on-your-s7-s7-edge-r1632/
The article is for S7, but see if you can have that working in the N4 - just have a backup of everything (int SD, ext SD, full backup in recovery).

I tried this in my phone. While the command itself worked after a bit of a tweak, the storage situation was pathetic - the phone showed the External SD as a part of the overall storage, but did not save files to it. Instead, it started saving files to the actual internal SD Card, resulting in space running out pretty soon. The External SD card was just there, and there was no way to migrate the files from the internal storage to the adoptable storage.

I just got a new Note 4 (this is the 3rd one I'm using since the first release in 2014) and I also want to adopt external memory card as my internal space bcos the 16Gg duos version is just too small and app to SD comes with a lot of hassles. After a lot of search for different solutions (which I tried out by the way but didn't work) I came across this thread for another phone entirely but it resolved my issue: https://forum.xda-developers.com/galaxy-tab-s/general/patch-adoptable-storage-enabler-t3460478.
The only downside is that I can't pop out my card (128Gg Samsung) and plug into my PC but I can still explore it directly from the phone itself.
I've been using the phone for 3 days and it runs smoothly, I hope that solves your problem too.

So there are two parts to the adoptable storage. The first part is the partitioned SD card and mounting the partition. Simple to be done via root essentials or the command line.
The other part is the actual menu entry on an app in application manager for moving it to the second partition. IIRC samsung does not have this support built in. So you need to flash something to replace that manager bit. In my experience with an on5 (like less than 1GB free on internal storage out of the box), adoptable wasn't really worth it, too much stuff still on internal storage. As not every app will allow you to move it to that second partition. It requires both system support and app support.
What I did there was to use the app apps2sd. Same idea, second partition on SD card. But it doesn't show up in settings -> storage. You manage where the apps go via that app. I use the link feature which places a symbolic link in the internal storage and moves all the actual files to that sd card partition.

I've been using apps2sd fot about a year and it comes with it headache too, sometimes the apps wouldn't find the external data (usually games with a lot of data) and it'll start downloading it again into the internal memory, so I usually find myself having to force stop the app, delink and relink the data on the memory card to fix the bind. I also didn't bother to partition my SD card since I can explore it on the PC with my phone connected. What this solution ( https://forum.xda-developers.com/galaxy-tab-s/general/patch-adoptable-storage-enabler-t3460478 ) does is to flash back the option to use the SD card as internal memory that Samsung removed from the phones and it works seamlessly on all Samsung phones with rooted stock OS.

I can't properly write on my SD

Ok, I have had many phones and this problem is a little bit weird for me.
I'm using Poweramp as my daily driver for music. I tried deleting some songs I stored on my SD and it said my files were write protected. I then used Root Browser just to see, that most of my music and photos I have on my SD card were not located in /sdcard but in /storage/57EF-B920, a directory I never created. When I put the SD card into my PC, I can see all my files normally and r/w without any issues.
I figured I could only alter files using the stock file browser and gallery app, but why? And why are my SD card stored media files showing up in /storage/57EF-B920 instead of their actual path? Is that a security feature?
My phone is 100% stock and not rooted.
Thanks for your help!

This is how it has always been on MM. The days of /sdcard, or /storage/extSDcard for your external SD card folder are long gone with LP/KK/JB I'm afraid.
The directory for external sd is unique to your SD card. Put in another SD card, and a new directory name will get generated for it, and it alone.
The ability for an app to write to SD card is down to the app's developer. It will need to have the updated methods that MM uses. Usually, if an app can write correctly, it will prompt you to browse to the root of your external sd card the first time it attempts to access it. Even then, some apps may need extra tweaking. Titanium Backup for example requires the storage type for the external SD card to be changed to Document Storage/Provider in its settings. I used to use Nandroid Manager on my rooted S4 on CM MM, and this could never update external SD card....I had to use Root Explorer to delete/rename my TWRP backups.
You can also double check specific apps for permission through Application Manager.
Go into the specific app in application manager, click on Permissions, and make sure Storage is turned on.
Even when turned on, some apps might still fail, as I've explained.

Sorry for the late reply, but thanks for the explanation! So it's because how MM works vs how Lollipop did and Poweramp not being uptodate with that? I'll try out the permission thing and even if I fail, it's good to know why it won't work. Thank for your help!
