This is a hack that that allows you to swap internal storage with your external SD card so you can increase your app data storage.
All credits go to original i9300 App2ExtSD Hack by mattiadj. I simply hacked it to work with U.S. versions and also I've added code so it will disable this feature when you don't have a microSD card inserted (app storage will default to internal when no microSD card is inserted).
E.g. If you have 16GB internal storage on Galaxy S3, you can install this witih a 64GB microSD card and swap the storage and get 64GB on your app storage instead of 16GB.
Before you can use this, you will need:
1) Rooted Galaxy S3 (SCH-I535/SPH-L710/SGH-T999/SCH-I747) or also Canadian versions too (i747m, etc...etc...)
2) A ROM/kernel with init.d support!
3) I've only tested this with TouchWiz-based ROMs, so it should work on stock ROMs and any TouchWiz-based ROMs, not sure on CM9 or CM10.
4) You must use the FAT32 or EXTFAT zip file below, depending on what format your microSD Card is in! (e.g. if you have a FAT32 microSD card, use FAT32)
To get this working, simply flash the zip files in your CWM Recovery:

If you are on stock ROM or any TouchWiz-based ROMs, you can flash my new HighOnAndroid kernel to get init.d support on your phone here:
http://forum.xda-developers.com/showthread.php?p=30718496
If you do not have init.d support, you can also enable on any rooted phone by using Script Manager, here's a quick tutorial:
I recommend you to FORMAT your microSD card once to get camera working flawless before using this hack!
How to disable this:
If for some reason you are having trouble, simply delete /system/etc/init.d/11extsd2internalsd.
OR
if you leave your microSD card out during boot (then re-insert it after), your phone will work as normal (internal storage used for app data).
Sounds awesome thanks

Is it best to wipe first, or will this move all the app data from the internal to the external for you?

It is best to do a wipe to start on a clean slate, or you can also copy the contents of your internal to external.
OR, I like using Titanium Backup to backup app and its data then restore after putting in the microSD card.
it works great, thanks for the mod, will report if I find any problem w/ it.
Great work max! I was using stock rooted rom.. Now I need to look for one I like that has int d support.
Thanks for this though appreciate it!

Would it be possible for you to create a Stock kernel with just the init.d supporthe?
My SD card is reporting "vFat" as the type......is that FAT32 or EXTFAT or neither? lol

I meant format. Sorry about that. Autocorrect got me again.
This is great! I'm curious if this mod sticks if I flash an updated/new rom? Do I need to flash this zip after I flash the rom? Also, what happens if I wipe my phone when I have this mod? Do I need to re flash as well?
Hi, I have a problem with my patriot signature microsd 32gb on my 16gb Samsung Galaxy SIII which I use as a music and picture storage for my music player and camera
The phone is rooted and is running stock ROM and kernel
The problem:
1)when transferring music files while the sd card is in the phone, using a usb and explorer method of copying and pushing sometimes the write protected warning pops up, other times the file would copy but I could not find it in my music player/gallery, other times the file is present for a period of time but after a restart of my phone the file disappears.
NOTE: However, files that I have transferred using the microsd adapter and directly through the computer does not change at all.
2)On the default camera I have set up the external sd card as the default location for pictures, but when I take a picture sometimes the warning that "sd card cannot be located and default storage is changed back into phone"
3)On Android Commander when I try to push music files it always ends up as permission denied
4)When I try to copy music through the windows explorer this message pops up "the device has either stopped working or is not responding"
What I attempted:
I thought it was a formatting problem and so I tried to format the sd card using both my phone and pc into the phone's desired FAT32 format,
but the problem persists.
I have also inserted the sd card into the adapter and put the write protected switch up thinking it was a permissions problem
Is it a faulty card? or am I doing something wrong?
Additional Note:
1)I have both ES file explorer and Root explorer and when I attempt to change the permission on my external sd card which usually appears in ES file explorer as "rwx-rwx-r(blank)x" it always fails
2)When opening the gallery and trying to view some of the photos saved in the external sd card, it would appears as unable to load and just a black screen.
3)I also export playlists from itunes in m3u format and puts it in a playlist folder in the sd card but it would never appear when I try to see it in a file explorer, although using poweramp I can import the list, but the old ones that I have placed on the card is also present unable to find them or delete them in either the phone or the pc
I have really became desperate trying to solve this problem
Please help me
Try reformatting as exFat. Also I don't think you can change the permissions on the entire sdcard.
It could also be that the phone connects using MTP. There's an app here on xda called sgs3 easy ums. It will mount the card as a UMS device. Try transferring that way.
I think the sgs3 was intended to use the exFat format though.

That's weird. If it doesn't pick up your card then the problem might be more serious than you think. But how can you see the contents and be able to format it yet utilities like Easus and SDFormatter can't see the drive? Did you try disconnecting all USB flash drives, your phone or other devices connected to your computer first? Check explorer and see to it that your card is the only one connected with a drive letter. Go to SDFormatter, hit refresh and make sure the drive letter is chosen.
SDFormatter just fixed the problem I was having.
You said you were rooted stock. Did you do any debloating or anything else to it. I doubt its the case but maybe something needed was accidentally removed.
Have you tried running fix permissions in recovery or TiB?
Also, how did you root? Was it recent and did the card function properly before? If you used odin to flash a rooted fw, maybe it was a bad download?
If all else fails, you could try reflashing the full stock fw with Odin.

1)I didn't do any debloating for my phone, and how do you run fix permissions in recovery? or TiB?
2)I root my phone by following this guide "How to Root U.S. and Canada Galaxy S3 SGH-T999/SGH-I747/SPH-L710! [Fail-Proof][Noob-Proof][U.S. Cellular]" using odin
3)So by reflashing the full stock fw do you mean I need to factory reset? or Is it possible to download the stock fw somewhere?
Sorry I am new to android, so please bear with me
Sorry, coulda sworn you could run fix permissions in Titanium....
You should be able to do this in cwm or twrp recovery. May be in the advanced menu. You can install the recovery from Rom or Goo Manager app.
Factory reset wipes all user data taking you back to an out of the box state.
You can get a pre rooted version of the FW from here.
http://forum.xda-developers.com/showthread.php?t=1771687
This is the original LE6 version though, if you want the updated LH2 version give me a few min to get the link for you.
Follow directions in that thread to flash with Odin.

Let us know how it goes. If noting at all seems to work, try borrowing a sdcard and see if it acts the same.
Could always just be a problem elwith the card itself

I had a patriot 16gb class 10.. when it works.. it's awesome should be called class 15 or something lol. However there were three times it randomly corrupts.. lost all my pictures and crap. A format usually fixes it. After the second time... i learned to put my photos to default internal memory. The third time i was no longer able to format it... couldn't move files in or out but i can open them?! I went with the high amount of 5 star reviews but should've listened to them 1-2 star reviews. They don't do well with phones. And your problem is a problem that occurred to me every now and then. Remember to back up your card frequently before it crashes!
Sent from my SGH-T999 using xda app-developers app
ah, problem
so I tried followed the link and the steps to flash the fw
but I am encountering this problem of when odin is done and the phone is restarting the "process android.process.acore has stopped" along with touchwiz and poweramp.
I reflashed twice and the problem remains
I even cleared dalvik cache and regular cache and fixed permissions with cwm and rebooted but it still did not fix the problem
Do I have to factory reset now?
:crying:
I can't remember which app it is or if this is the one requiring factory reset. Can you boot and get to settings > app manager? If so clear data on google services framework. Maube also touchwiz home. (Can't remember for sure)
You could also try using the built in file manager in twrp. Go to /data/data and look for those folders and delete them. May not work but worth a try.

ya thanks for the advice but it didn't work
From what I can tell the only solution now is to do a factory reset
anyways so why did the fw not work for me?
i even made sure i downloaded the correct wind one
at least now maybe with the factory fw i can make sure the external sd card works?
so factory reset is done
external sd card still does not want to work via "my file" folder creation
I don't know is it broken? I would like to try another sd card but I need to find one
although I did test it with h2testw and no error message popped up.
It wrote and verified fine.
Sometimes left over data can cause problems with a newly flashed system. Odin didn't wipe your apps or data and something was left behind that conflicted with setup or something like that. Sorry it came down to that man.
Ive heard a few times over the past couple years of sdcards working fine in one device but not at all in another. It seems rare and I'm not sure why it happens, but it can.
Only way to know for sure is to borrow a known good sdcard and try it. If it also doesn't work then its most likely a problem with the phone. If it works then you probably need to replace the card. Maybe take it to the store where you got it and let them try. That way if it doesn't work you have a witness that can note your account of the issue.

Spent the better part of yesterday fighting this and I'm cooked. I can get any ROM to load. I just have no data other than Wifi. Baseband shows unknown in About phone and I can manually load a modem. Makes no difference. Convinced it's related to the storage issue. Was not able to format anything on the internal card in CWM so went to TWRP and was able to fix the Can't mount /sdcard and /data issue. But didn't help the storage issue inside the ROM(s).
I can't tell you exactly what I've done step by step becaue I literally worked on the phone for 6 or 7 hours yesterday between ODIN and custom recoveries.
Anyone seen anything like this? I can do some screenshots but what happens when I go to settings and storage is I see a brief screen flash of the various storage capacities. ex applications (calculating), Pictures and Video (calculating) Videos (calculating) etc... but then all but the Applications disappears. I am left with Total Space 0.00B and Applications 373MB. The external card is fine. Total Space, Available Space Unmount etc...
What appears to be happening is I have no internal storage available other than the 2GB or so that the system takes. Camera immediately gives errors and auto switches to external card. If i pull the card I can't take pictures. this from a newly formatted SDCard in TWRP.
I actually did this to my phone on purpose. T-Mobile rep would not honor my exchange request for a screen issue claiming they could not see what I was talking about. So I came home and flashed the .pit and bootloader from a chinese Note 1. It made my baseband, IMEI and all data dissapear. The internal storage was also borked from the pit file I flashed. Same camera issue, and the gallery would immediately close saying it had insuffiecnt space. My best advice would be to flash a stock tar/md5.

I think there are two problemz with the external SD card on this Lollipop build.
1. Permissions which I think the play store app fixes.
2. The format must be FAT32. I don't think I've seen a fix for this, unless you want to reformat your SD card.
My SD card did die as well. I'm not sure if it's related to this update or it was just it's time. Mine couldn't be read by anything. I have sent it in to Lexar for replacement.

Mine works fine. When I installed the 20b ROM, I did a complete wipe of everything in TWRP except external_SD. Installed the system, modem, boot and bootloader images and booted up.
Had issues with some apps like DoggCatcher being unable to write to external_SD despite that being the save data path. Ran the app I mentioned above and now all works fine.

How big is that card, the only thing holding me back is the reports of 64G+ non FAT32 formatted cards not working... I use the phone as a FTP server or sorts and need larger file support than FAT32 has given me.
