[Q] Samsung Tab 2 Apps to External SD Card - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi all,
I've just purchased a Samsung Tab 2 7.0 P3113 due to the fact that it has an external SD Card slot. I have found that I can not move any applications to the external card. This was one of the primary reasons I purchased the device. I have been using android devices for a while and my first Sony X10, was rooted and running custom roms within the first few weeks after I purchased it. In any case, I have read a number of threads, regarding this subject for the Tab 2 but I have not been able to have an installed app be moved to the external SD Card. Most post will say you have to root the device, (which I have) and use apps such as App2SD. I have even gone as far as loading a custom ROM, but no success. My last resort is to actually partition and repackage a ROM for an external 64GB SD Card and attempt to boot off of it so I will have more space. If anyone has truly been able to move an installed app to the external SD Card could you please point me in the right direction.

I would like some help on this too. But the silence is haunting.

Found this under a compilation thread that covers the 3113's and is down further on the same page in this forum.

I hope this helps and sorry for the re-re-re editing
AFAIK (and correct me if Im wrong veterans), is a defect of the OS not hardware. ICS and JB of the GT2's do not allow it as the internal memory is already labeled as sdcard. or that seems to be the prevailing opinion so far. I would like a work around but short of flashing a custom rom and/or kernel it seems unlikely to happen. Downside to that is some things don't work all the way in some roms. Ahh for the old days of my stock+ on my incredible. wait. Im still using it from back last summer and it works fine. TY wildstang!!

Hail Link2SD !!
Only way to move Apps to ExternalSD is using Link2SD for ICS / JB. I have done lot of research and there is no other way.However Link2SD does not move the data files and hence your internal memory will still be filled up as and when you install more apps but at slower rate.
If you want to install games like NFS-MW , Asphalt etc you have to use DirectoryBind tool to move the huge data files (More than 1.5 GB) to external card.
There is a nice tutorial how to use Link2SD here on the forum (http://forum.xda-developers.com/showthread.php?t=919326).
You can use ext4 partition as i found ext2 and ext3 were not being recognized by Link2SD. Just a pointer.
PS: ICS and above no longer support moving apps to SD card. If i am wrong experts correct me.

root is your best bet. check this link, use the script and follow the directions. this script worked wonders. my tab thinks i have 32 gb internal and 4gb sd.

[Q] Difference between Root App2SD and stock Froyo App2SD

Hi all,
I've been searching through the forums and didn't quite find an answer, so sorry if this has been explained before.
I'm currently running an HTC Desire with stock Froyo (i.e. not rooted). Also, my knowledge of rooting and all its benefits is rather slim, so please bare with me. As some of you might know, the internal space on the Desire is rather on the low side, so I used adb to enable all (well, most) apps to be installable on the SD card (adb shell pm setInstallLocation 2). Now, with this, the apps themselves are moved onto the SD card, but their data and/or cache is still being stored internally. Effectively this means in the long run I still run into the ol' storage space problem.
Now, I read how when rooting a phone you create a partition on the SD card to be handled as if being internal space. Does this mean the above mentioned data/cache/all that jazz that would originally stay in the internal storage when using App2SD with a stock Froyo rom would also go onto the SD card, effectively not using the 'real' internal space at all for apps?
I might have to add, the possibility of a 'real' App2SD might be my highest, if not only motivation to root my phone. So if those two methods (rooted vs. non-rooted App2SD) are basically the same (space saving wise), I might as well disregard that notion.
Thank you in advance.
--Jakob
no they don't work the same
if u root your phone and install Darktremor app2sd it will move to ext partition on sd app+data+cache+dalvik cache
so u will end up with a lot of internal free space
and also from then on all your apps will be instaled to the ext partition

Where is it really saving Apps\Data?

So this is the first phone I've seen where it has SYSTEM memory, SD INTERNAL, and SD EXTERNAL. It's really confusing for me.
When I install an app, is it installing to the 16GB built in memory, or my SD card? I haven't modified anything. And if I do a backup using MyBackupPro, is it using the on board, or the SD card?
It seems like everything favors the internal 16GB, so I guess the 32GB I slid into the device should just be used for things like movies and photos, etc?
I guess this confusion is hampering CWM too since it's not used to handling both these "SD CARDS"
Thanks!

This also brings up another question. Once ROMs do come out as a result of CWM being modified, normally someone does a format\wipe data\clear cache. This would normally clear anything on the "internal memory"... but since there's some confusion as to if the phone sees the "internal SD" as internal memory or not, do you think this process will wipe that as well?
No confusion. I think you may be confusing yourself in a vicious circle
Everything by default is added to the "internal" SD. There are apps (app2SD) and other ways(GB) to install apps to "external" SD, but not all apps can be.
Backups are saved on "internal" SD. (MBP, i dunno, I use TiB) This folder can be copied to "external" SD BEFORE a wipe and flash, then copied back to "internal" SD, backup program installed and restore apps+data preformed(copying the backup folder to pc suggested also in case All goes Wrong) .
"System" is on "internal" SD but is on a different partition, as well as ROM and Internal DB to their own.
CWM has no issue with SD (internal/external SD'd are not new) but as phones and hardware are different for different models it must be modified for the device.... par for the course. As far as how to CWM ROM, always do as OP of ROM states, until you are at least familiar with the process.
Is this your first android device? or first Samsung? I recommend that if you want to understand better how these devices operate to read the Galaxy S family of forums ( Galaxy S, Captivate, Fascinate, etc) as there is tons of info that will be similar to the Infuse.
Hope I ain't steered you wrong and it helps

Yep. The 16gb internal sd is partitioned into a 13 gb and some change (/sdcard) and 2gb (/data). Then the external sd is mounted as /external_sd.
/sdcard and /external_sd are supposed to be used for media (try taking a 2 minute video at 720p res lol...easily 40-50mb) and android devices usually have a 2gb data partition where your apps install (supposed to install by default).

Moving apps to ext. SD card

Hello all
this is my first android phone.
i managed to move some apps to sd card, but only to the internal.
How can i get them to the external sd card ? the ext. card is a mount point inside the internal one, thats what i found out.
Cheers
Lorien
At this stage it cant be done.
Oh, so is it a specific problem with the LG FW or is it the current Android OS ?

It's a limitation of the Android File System in general, not of froyo, gingerbread or ice cream sandwich. This is how the OS works.
What you can do is to go the the phone settings then programs then app manager and there click one by one the apps and choose to move to the SD card. You will notice that you will still have a portion of the app running from the phone memory. This is something that you have to live with for the time being but at least the half of the app should have been moved to the SD so at the end of the day you will gain some space.
Yes thats what i already did, worked great, but i do still have a almost empty ext. sd card. All the apps i moved are still on the internal sd card.
How about using apps2ext ? This is a modified version of the original (pre froyo) apps2sd that uses a "hidden" ext2, 3 or 4 partition on the SD card. I can only find it as part of custom roms. I'm sure it needs root to work too?
Anyone know if that would work?

I think we might have success with that actually. I will give it a try and I will let you know.
Any progress in this matter ? My internal SD Card is already full ! Have to start removing apps to install others.
I think those Android OS limitations are pretty wierd, so the ext. card slot is just for photos,videos on an android phone then ?
I did try to use darktremor on this phone but it won't work on stock firmware. I think that we need to wait for CM7 before we are able to install the whole app on the external SD.

The main problem is not the apps themselves. So Darktremor's A2SD would not help. The problem is, the extra files for large games are automatically downloaded to internal sd memory. Which is limited to 7GB. New games require more than 500 MB's each, so 7 Megs would be enough for many of us, but not enough for some of us.
It is certainly enough for me right now, but you cant see what future brings.
Hi guys,
I'm having this problem now.
Basically, my internal memory is being used by don't know what and I have left around 400mb.
The problem is that I cannot download more 3D games, they require around 500mb each!
I have tried to delete photos, videos and apps that I don't use but even like that it's not enough.
So now, I have a empty SD Card of 16GB and a phone/system that doesn't let me use that free space for "nothing".
BTW I did transfer the internal apps to the SD card, but very little changed.
Does anyone managed to find a solution for it? how can they sell android phones claiming that you can expand the memory of it if you are not able to use that memory for apps?
I already feel sorry for those that have the Evo 3D which apparently comes with 1GB internal memory.
And how can I move the 3D games to the SD card?
i think we have to wait until firmware update .. right now still behide 2.2.2 not even on 2.3 yet .. so i think we could move all app to ext card until 2.3 or higher.. i have try all the app out there .. not even one of them working .. you can move to internal memory but not ext sd card ..
you can also resolve this problem by switching internal and external memory. this works fine for the phone but messes up mass storage mode in windows! so you will find problems mounting your sd-card in windows - so you have to use alternatives for file transfer (ssh, ftp, adb) - means this is pretty much for advanced users only

LinktoSD + Beans10 = ?

Yes, I am a noob. New to Android but not PCs. I have searched all morning for an answer to this question and I am not eligible to post in "developers" yet so I am at your mercy.
Phone in question is box stock SCH-i535 @ 32gb. Will be using 64gb SD card class 6. I want to run BEANS ver 10 TW rom.
Here is the question: Is 'LinktoSD' compatible with or even needed in BEANS 10? If it would be useful in this ROM (to move as many applications as possible to External SD) should the required 2nd partition on the SD card for 'LinktoSD' be formatted as ext2 / ext4 or FAT32? I will probably size it at 2gb.
Any help would be greatly appreciated. I'm just not sure about the best approach with BEANS 10, or if 'LinktoSD' functions are replicated in that ROM. (?) Or if BEANS 10 would have problems with the ext4 partition?
Thanks to this site and all the developers & contributers for making all this great information available to a noob like me! :good:

Thanks android 94301, according to the OP he thinks it should work on any custom TW ROM. In theory, that would include Beans.
I hope someone who has tried 'LinktoSD' on a Beans ROM will chime in. I'm still waiting on my SD card to arrive in the mail so I haven't started yet.
I suppose I could play it safe and install both SD partitions as FAT32 for 'LinktoSD', load Beans10 to see what provisions it contains for moving apps to SD, and if I feel I still need 'LinktoSD' the SD card will be ready. Then I could try installing 'LinktoSD' over Beans10 to see if they play well together. If I understand it correctly, 'LinktoSD' redirects to the SD partition on boot. Beans10 will have to allow it. (?)
Someone with more experience than I have may be able to comment on the compatibility of the two. I'm sure I'm not the only one thinking about this. The feature set on 'LinktoSD' looks good to me.

That could be true on the developer's thread you quoted above. Zedomax describes that process as a 'hack' based off another program. What he's doing sounds similar but I don't believe he is basing his effort off of the 'LinktoSD' program itself. In that effort several people did report problems. 007willieruiz reported that CM10 needed a custom script, droidstyle reported that the kernel would need int.d support to work. Sshams95 actually did run that hack on the Beans ROM and ended up with duplicate file entries. That's all a bit too far out there for me.
What I was asking about was far more basic. Just running the 'LinktoSD' program itself, on the Beans ROM. The goal being to move 'active programs' (where memory speed is not an issue) from internal memory to the SD card, freeing up as much internal memory as possible for other things like (in my case) off road navigation programs and topo maps that will be resident on the device. 'LinktoSD' is showing downloads in the millions so it shouldn't be much of a stretch to think it's been loaded on a custom ROM somewhere. I should probably reserve judgment untilll I have the Beans ROM loaded, as it's memory management capabilities may be enough.
Input from Galaxy S3 / Beans user?
Well, after more web searches it appears LinktoSD has been and is being used on custom ROMS as expected.
(Since I haven't done 10 post I couldn't submit the link.)
The biggest problem for that user group seems to be broken links to the second SD partition after flashing another custom ROM. I still have not been able to find an example of it being used on a Galaxy S3 running Beans ROM. Anyone?

After reviewing approximately 250 pages of threads and post using over a dozen search phrases related to better utilization of the external SD card on the GS3, I found a few bits of information. I'm posting again because I think this will be a relevant issue for most GS3 users sooner or later. While there were several post speculating that the GS3's internal memory is enough, several users reported running low on memory after installing 15 to 20 applications. If you look at the GS3's processing power compared to it's total available memory, it's memory that comes up short. As a disclaimer though, I'm new to Android and to the GS3. Since I had to invest 3 days in the search, I thought a brief summary of the search highlights might be helpful to other noobs like me. I'm also hoping that those in the know will chime in here and share their insights. I've tried to give credit to the original posters in the info bites below.
As someone who is setting up a new SCH-i535 with the intent of running a custom ROM and being able to fully utilize the external SD card, I need the SD card installed and formatted first! The type of SD card / memory management you choose can determine how the SD card should be formatted, so this decision needs to come first.
Problem #1: The S3's internal storage is named SDCARD, the actual external SD card = SDEXT. This creates problems for programs wanting to write to the external SD card. This means that currently Link2SD, App2SD, Data2SD, etc. all have problems working on the GS3. On the GS3 the SD card is secondary not a primary external. It is seen as emulated. There appears to be no solution without Rooting.
Zedomax has this self described "hack" that swaps internal storage with your external SD card so you can increase your app data storage. This appears to shift everything to the SD card with no UI or controls. The good news is he developed it specifically for the GS3.

Kierrok reports this insight for Data2SD:
20. What are the requirements for using the “Move app data to SD card” (Data2SD) feature?
Our Apps2SD scheme creates symbolic links (one per app) at /data/data/com.x.y that will point to somewhere within an ext2/3/4 partition on the SD card.
The supported mount points for the ext2/3/4 partition are:
/system/sd/ (“classic” sd-ext)
/sd-ext/ (“Cyanogen” sd-ext)
/data/sd/ (“MIUI” sd-ext)
So for Data2SD to work, you’ll need to ensure that your ext2/3/4 partition is mounted at one of these locations. Then create an “app” directory at that location in case it doesn’t exist. Once it’s done, you’ll see a free space gauge for it in the Titanium Backup welcome screen, and you can then long-click on an app in the list and hit the “Move app data to SD” button. Once you do that:
First, Titanium Backup will look for existing symbolic links in /data/data/ and attempt to re-use the same target location, if it lies within the ext2/3/4 partition.
If it finds no existing (or no suitable) destination, it will propose to create a “data2″ folder within the ext2/3/4 partition, and will then move the app’s data inside it.
So by default, you’ll get: /data/data/com.x.y => /system/sd/data2/com.x.y (in the “classic” sd-ext case).
Then there is a complete program that offers the ability to move programs back and forth between device and external SD storage. However, the problems cited above create problems for Link2SD.

I am most interested in the Link2SD approach. I have posted or PM'd the users who claim to have this program working on the GS3 but as of this moment, I have not heard back from any of them. So, while still looking foreword to input from more experienced users, I am going to proceed down the path of running this program on a custom ICS - TW based ROM (Beans is looking good). If my device flames out and burns a hole through my desk I'll post a photo so you can all have a good laugh.

20. What are the requirements for using the “Move app data to SD card” (Data2SD) feature?
Our Apps2SD scheme creates symbolic links (one per app) at /data/data/com.x.y that will point to somewhere within an ext2/3/4 partition on the SD card.
The supported mount points for the ext2/3/4 partition are:
/system/sd/ (“classic” sd-ext)
/sd-ext/ (“Cyanogen” sd-ext)
/data/sd/ (“MIUI” sd-ext)
So for Data2SD to work, you’ll need to ensure that your ext2/3/4 partition is mounted at one of these locations. Then create an “app” directory at that location in case it doesn’t exist. Once it’s done, you’ll see a free space gauge for it in the Titanium Backup welcome screen, and you can then long-click on an app in the list and hit the “Move app data to SD” button. Once you do that:
First, Titanium Backup will look for existing symbolic links in /data/data/ and attempt to re-use the same target location, if it lies within the ext2/3/4 partition.
If it finds no existing (or no suitable) destination, it will propose to create a “data2″ folder within the ext2/3/4 partition, and will then move the app’s data inside it.
So by default, you’ll get: /data/data/com.x.y => /system/sd/data2/com.x.y (in the “classic” sd-ext case).
Then there is a complete program that offers the ability to move programs back and forth between device and external SD storage. However, the problems cited above create problems for Link2SD.
The actual Developer's thread for the program:

Dimerk reports that he has Link2SD working on the GS3.

I am most interested in the Link2SD approach. I have posted or PM'd the users who claim to have this program working on the GS3 but as of this moment, I have not heard back from any of them. So, while still looking foreword to input from more experienced users, I am going to proceed down the path of running this program on a custom ICS - TW based ROM (Beans is looking good). If my device flames out and burns a hole through my desk I'll post a photo so you can all have a good laugh.

Great info. I am still trying to find the magic program that will move apps to the Real SD card. I wonder if making one of the App2sD programs a system application would help things?
Got through the ROM.
As I configure a device I keep running notes. I'll share these as they may help other's who are completly new to Android. They are cryptic but should still be of value.
I'll format the SD card to work with Link2SD > Used Mini Tool Partition Wizard, 2 Primary Partitions.
1st / 57.5gb / FAT32 2nd / 2gb / EXT2
Rooted with: "GS3DebugFSRoot R2" / Unlocked boot loader with EZ-Unlock / Copied internal file structures to External SD Card. / Loaded EZ-Recovery as per guide.
Note: The following caused problems - Must load the apps to be run at the root of internal storage. / Launch Superuser app before running EZ-Unlock, etc. Superuser may not run properly as those apps are launched if you don't run it first. / EZ-Recovery navigates via swipe screen. / Boot into recovery navigates via volume & home buttons. / The stock ROM links in the guide are bad, see P-19. / You only need to load a ROM via desktop ODIN, not a kernel, P-22. / "Wipe Data - Factory Reset" is necessary to prevent bugs & errors on status bar.
Finally got Beans 11 up & running, but I may not keep it. I'll load Link2SD when I've found a ROM I'll stick with. Still deciding that issue.

Well fellow noobs, it may be time to close this little thread. As far as I have been able to discern, none of the conventional programs for moving applications to external SD cards mentioned above are compatible with the GS3. (The one script is.) I'm hopeful the developers will eventually port these programs to the GS3. I've contacted one of them. As far as need goes, my device only has 2 market apps loaded and is running with 30% of system RAM used. I know that is a bit deceiving as Android is going to use the RAM if its there. Still, I have about 15 more applications to go and will be paying attention to conventional memory management practices to keep as much RAM available as possible. As to the other half of the thread title, I have switched to a more conservative ROM that I am much happier with. I am learning as I go with the help of this forum and so far, I really like the device and the new to me Android experience. I do find The Play Store's instance on WiFi / Cell downloads directly to the device and strictly from them to be a bit odd for an 'Open Source' community though.

How to install apps in external SD Card

Hi All,
I've two tablets and the internal free space in getting lower, I need to install apps directly on their external sd cards. How is it possible? All the "2SD" apps don't work.
Thank you all in advance :good:

You can't unless you root the tablet and use non standard software.

Really...... I was under the impression that it could not be done at all.
Please tell how as I would like to know also.
Thanks.

didnt figure this out but u can use titanium and move those on the device to leave more space for other installations.
If you are rooted and on a stock ROM or ROM not using JB 4.2 (Google changed the file structure again in JB 4.2), you may be abe to use zedomax's script that swaps the internal and external SD cards. Although it's long, I would suggest reading through the entire thread as glitches with the stock ROM update to JB 4.1.2 and work arounds are addressed later in the thread. http://forum.xda-developers.com/showthread.php?t=1857391&page=1
I'm interested in this as well. I read a post on something called a directory bind...??? I guess that moves app data to the SD card. I currently have just over 9 gig of space left to fill (16gig model). Just put in a class 10 32gb card in last night to find out that app2sd does not work...
I read today that link2sd might work. Haven't gotten a chance to try it yet though.

I tried link2sd and the other one mentioned in this thread with no luck.
I don't really want to do the the card swap method.
So........... if anyone has another way to store apps on a mico sdhc card that truly works, I'm in.
Found app that truly works
I finally found an app that truly transfers your app data to your "extSdCard" but you do need to have root.
The app is called "Directoryblind" and can be found here http://forum.xda-developers.com/showthread.php?t=1410262 and the most current file is DirectoryBind_0.2.0o.apk
The app has been out since 12-2011 with many updates since its release.
So I'm posting it on this Note 10.1 section as I have never seen it talked about in this section and I thought it may help someone else find this app.
Again it truly does work.
