[Galaxy Y Duos S6102 Android Development] Kundal:
Yeah, I removed more than 45 apps from /system/app and moved about 35 of my own apps there. I replaced Launcher, Music, Keyboard, Gallery, Browser etc. and moved Link2SD, Titanium Backup and much more that's essential enough for me to have it working even when I remove the SD-card. I think it's good to move as much as possible to /system/app. Leaving more than 10-15 MB free space there is wasting space in my eyes. But everyone may use his own preferred strategy.

On my device free space is 30 MB at the moment because I recently gained about 36 MB free space by the repacking method I described (I didn't repack apps that updates every few days like Titanium because I don't want to repack them after every update). It was down to 9 MB before and I'll move some more apps there.

If an app doesn't work when converted to system app it's because it can't find it's libraries anymore. Moving the libraries from /data/data/[appname]/lib to /system/lib before converting it makes it working in most cases (don't forget to do this again before integrating an update).

The script (from a thread of kurotsugi) is very simple:

#!/system/bin/sh
# cleaner
rm /data/anr/*
rm /data/cache/*
rm /data/log/*
rm /data/tombstones/*
rm /data/system/dropbox/*
rm /data/lost+found/*
rm /dev/log/main
[Galaxy Y Duos S6102 Android Development] MNgez:
Thanks mr kundal...

I'm wasting it since i'm not moving some apps to system partition.

About the script... i think u have your own...

so its kurotsugi script... can i have the tread link please.

[Galaxy Y Duos S6102 Android Development] Kundal:
It's only one script out of a compilation. Like me kurotsogi didn't write all the scripts himself but collected them from several xda threads. The cleaner part is integrated in 06kuro1. I added rm /data/lost+found/* which I found elsewhere. The app SDMaid cleans up the same folders.

Attention: You shouldn't flash the package as it is without understanding what every single script does. I had to delete/edit some things to avoid problems with my device (e.g. the gps.conf, 01adata and several things already provided by the iDuos kernel).

[Galaxy Y Duos S6102 Android Development] kaorukail:
it's possible, but it will slow down your phone, because there's some file that should remain in data partition, because it's faster than sdcard second partition.

Thanks MNGez! btw, how did you manage to view your second partition in Titanium Backup? You're using Link2SD, right?

Thanks Kundal for sharing! :)
[Galaxy Y Duos S6102 Android Development] MNgez:
Yup... i prefer not to move or link all dalvik cache to sd card. It's not only slowing down our device, but also many apps would not run, force close or make make our device not running properly. So make sure to move what u need. But let it be in internal for some apps spacially for system apps.

About my second partition in Titanium Back Up...

Hahaha I'm using a2sd beside link2sd.

Now they are not make any war in my device lol.

Tree of us (sgyd12, MNgez, kecrekchord) already using this trick for long times. Actually its sgyd12 trick all credits to him, thanks to sgyd12 for always help me all the ways.

In so many reason a2sd is not running a2sd data2sd and also cachesd before, Because of link2sd script.

But now i found the reason why. We must make sure link2sd not link anythink to sd-ext2.

We do like this...

1. First of all put and install supported apps in system partition (/system/app and etc.), so put there:

superuser/superSU (i'm using latest superuser and also get ellite),

Latest busybox (i'm using 1.20.1),

a2sdgui (i'm using a2sdgui donate 1.03),

and link2sd (i'm using link2sd 2.1.2). Install and run them all but for a2sd and link2sd don't run it yet, just install it.

2. Run link2sd and run the script to for ext2/ext3 not support ext4 if u want a2sd run also. Reboot

4. Install latest a2sd script under cwm and reboot

5. Make sure sd-ext2 is already in internal (/data/sd-ext)

6. Run a2sdgui activate zipalign and all function. Also u can go to terminal emulator for running a2sd function for data2sd, cachesd and swapping and etc. But for good dont do cachesd, i link it manually to make sure i aint move important dalvic cache.

7. U can see now in TB there is sd-ext2 for a2sd.

8. Finish and enjoy them running properly in our device.

We do this under Stock rom becouse a2sd is not running well in stock before this.

[Galaxy Y Duos S6102 Android Development] kaorukail:
Okay, I'll consider using it :)

Thanks!
[Galaxy Y Duos S6102 Android Development] MNgez:
Your welcome my bro...

So this way we consider that link2sd has better script to mount/unmount and remount sd-ext2 (ext2/ext3) partition especially when rebooting, Not just like a2sd script in stock rom.

After this we can do a2sd function as well as in custom rom.

I'm using a2sd for app2sd, data2sd, zipalign, and swap.

I'm using your way to link dalvik cache manually to make sure i aint moving some important dalvik cache.

THANK YOU VERY MUCH MY BRO.

Dear Kaorukail and all

I'm in confuse now about link2sd.

I cannot creat link2sd script. Whats it's all about. Is it because i don't have mmcblk0p0, mmcblk0p1 and mmcblk0p2 in /dev/block.

Or why? can u help me about this?

I'm in Stock and iDuos1.3.1.

Also i cannot backup via cwm it's alway faild to pack system.

So what should i do?

Yes ext4 is the problem.. which partition is ext4 now? All kernels of duos has that problem I feel.. it needs some modification in ram disk to fix it.. maroc-os has done that.. as no one uses ext4 this couldn't be tested.. so if you are ready to test.. I can try to make one.. if it works.. i will put that ramdisk for your kernel with the permission of the dev of that kernel..

Or for easy fix.. convert it to ext 3, ext2.. problem will be solved..

[Galaxy Y Duos S6102 Android Development] rsanchez1:
I realize this thread has not been updated in a while, but I'm wondering if it's possible to link app data that has been put on the SD card 1st partition to the 2nd partition. I have my two partitions about the same size, and some apps, like Gameloft 3D games, download app data (textures, etc) to the SD card. I'm running out of space on the 1st partition, but have space on the 2nd partition.

The reason I'm asking is because I don't want to go back and resize the partitions, and since this method moves private data from internal to 2nd partition, I was wondering if something similar is possible from 1st partition to 2nd partition.
[Galaxy Y Duos S6102 Android Development] Deadly:
Why don't you just link those apps which you want to move into second partition using link2sd method? Then you can use a2sd method here to link data too..

This way your problem will be solved.. give it a try

[Galaxy Y Duos S6102 Android Development] rsanchez1:
Oh ok, I was asking because this method was for data in /data/data, but if it works for data that is in the SD card 1st partition too I will give that a try. Thanks.
[Galaxy Y Duos S6102 Android Development] Deadly:
Well thing is... when you move from link2sd.. your data will be moved to /data/data... as the app in second partition is considered to be an internal app... so, the latter work and suggestion told..

Btw, don't hate the thank button lying around there at left corner;)

hi guys,

want to ask about root explorer, i follow the instruction on page one,

but after move the data files then long tap i cannot see " link this folder" on my root explorer option?

how to show this option on my root explorer ?
[Galaxy Y Duos S6102 Android Development] kaorukail:
make sure your root explorer is up to date. it's only available for v2.21 or above I think :)
[Galaxy Y Duos S6102 Android Development] kaorukail:
well the thing is.. you can't. as far as i know, you cannot create any symbolic link on FAT/FAT32 partition.. I also wanted to do this for my ringtones, I wanted to link my music files in another folder to /sdcard/media/audio/ringtones.. :(
[Galaxy Y Duos S6102 Android Development] Deadly:
Yes, its because symbolic links are Linux feature and only supported on Linux partitions..

[Galaxy Y Duos S6102 Android Development] tannalein:
This worked like a charm, thanks. I have just one question, though. Before running onto this post I tried Titanium Backup way of moving the data, which turned out to be a total disaster, but in the process Titanium created a data2 folder on the SDext2 partition and tried, unsuccessfully, to link the data there, so what I did here was to leave all the libs linked with link2sd, but linked the data with root explorer to the data2 folder (I wasn't really thinking what I was doing, I just thought since Titanium tried to link it there I'd do the same, but later I've noticed your did it differently in the tutorial). Everything works fine, but I'm not really sure where everything is. Is the data copied twice on the sdext2? I wouldn't really mind if it was, there's enough space there, I'm just wondering how will it effect the performance or battery? Does the app link to two folders now instead of one?
[Galaxy Y Duos S6102 Android Development] kaorukail:
I think it will affect the performance a little, since it will search for the linked file 2 times. Link2SD link the lib folder that you also link manually with root explorer. So it goes like this :

Original folder -> Data2 folder -> Link2SD folder

So to make things not complicated, don't link the lib files with Link2SD, because when you link manually with root explorer, the lib files will be linked too.
[Galaxy Y Duos S6102 Android Development] tannalein:
Turned out some of the apps force-crashed this way. It works the best if I link the sub-folders of the app data, like Kundal suggested on page 3, because even if I don't link the libs with Link2sd, I still get the "Relink all Application Files" error. If I link sub-folders, I get the error the first time after I link it, but if I run the "Relink all Application Files" again, it runs ok. And the apps seam to work without crashing now.
[Galaxy Y Duos S6102 Android Development] HughGRection:
Thank you so much for this tutorial OP!

I have been struggling with my phones internal memory for so long. I have an HTC Wildfire S that only has 150mb of usable internal storage. Apps such as Facebook, Flipboard, Media Storage, Google Play Services, etc... have horrendous amounts of user data that take up (in total) of about 120mb of storage on my phone. With this tutorial I was able to free up quite a bit of internal storage, which in turn noticeably sped up my phone!

[Verizon Samsung Galaxy S III] SirKronan:
I am wondering if any of you fellow Verizonites would be willing to help me test this out, as I have already asked my friend with the AT&T version if his does this, and it does not:

When connected to the aux in (very common on cars and stereos nowadays, you know, so you can listen to music off your phones and iPods and MP3 players, etc.) I now have the SAME incredibly aggravating problem I could never resolve with my Fascinate. As usual, I have my bluetooth connected to take the call. When I answer the call, I hear NOTHING over my bluetooth unless I disconnect the audio cable out of the headphone jack!!! This is a huge safety hazard, as it takes your hands and eyes off the road, requiring you to disconnect a cable every time you get a call!!

I called Verizon and complained about this with my Fascinate to no avail. I never had this issue with my Droid X, HTC Eris, or my Galaxy Nexus, another dual core Snapdragon based Verizon LTE phone made by Samsung.

Not to mention the SGS III is laggier and less responsive than my Nexus, although not as bad once you disable S Voice (S is for stupid, by the way, at least in my opinion ... I can't get it to work worth a darn!! Could be that I'm the stupid one, but I've certainly given it a lot of effort in a very quiet environment.)

This is horrible because the screen is incredible, and the battery life far outpaces every other smartphone I've ever had by a ridiculous margin, so PLEASE, fellow Verizon SGSIII friends, help me out if you can!! I don't want to have to return this phone, but reasons to do so are stacking up.

If there's no fix for the audio cable thing, that is a definite deal breaker, and enough to make the phone "defective" in my opinion. That is such a blatant safety hazard. I do NOT want a "Fascinate 2". The other issues pale in comparison to the audio cable issue.

Here is a video of the AT&T version NOT having this glaring safety and functionality issue:

http://www.youtube.com/watch?v=A37p4fF-h-k
[Verizon Samsung Galaxy S III] macdroid01:
This is a glaring safety issue you are right. I planned to have bluetooth on my ear to take calls but have the phone plugged in for music on my car speakers.

The other thing is I bought a Samsung HM7000 thinking it would work with the SAMSUNG S III. Pff. I guess FreeSync App doesn't support the S III yet. I will definitely express to Verizon/Samsung why I have to return this headset if this isn't solved in a few weeks. I will contact Verizon on this.

So this doesn't affect other US Galaxy S III units only Verizon? That's so weird but it also suggests it's an easy fix.
[Verizon Samsung Galaxy S III] frifox:
I tested it with Bose Bluetooth earpiece and that works, somewhat. If you have the Aux plugged in and get a call, the phone picks up your voice from the Bluetooth and plays the other guys voice through the Aux. Unplugging the Aux mid-call will route the other guys voice back to the Bluetooth. In both cases both me and my friend could hear each other.

There is a problem though. When the Aux is plugged in, with Bluetooth our not, the call quality will drop significantly. It will sound as if you're in a horrible signal area and will cut out every other second or so making it impossible to carry on a conversation. Funny thing is as soon as I unplug the Aux the call is back to normal and we can hear each other just perfect. It's as if with Aux the noise cancellation kicks in and starts cancelling out everything, including your and the other guys voice, lol. Not sure if that's just my phone or SGS3 in general. I actually intentionally used this "glitch" to avoid taking to annoying person. Just tell them "I'm in a bad area and can't talk" and plug in the aux mid-call and they will stop bugging you as soon as they hear the voice glitch up :D
[Verizon Samsung Galaxy S III] insight3fl:
My bluetooth headset works fine with the audio out through the "dock" connector.
[Verizon Samsung Galaxy S III] adsbar:
Same here

Using bluetooth in a 2009 infiniti, AUX jack prevents proper bluetooth calling or receiving. I had come to rely on this in my other phones (HTC).
[Verizon Samsung Galaxy S III] PSUmech:
same here too

I upgraded from a fascinate to a s3 and have the same problem on both phones. It is really annoying and I'd love to find a fix for it.

:(
[Verizon Samsung Galaxy S III] xceebeex:
I think I am having the same problem with the Bluetooth in my 2010 G37. It seems like if u connect via Bluetooth for media audio, I can't get calls and vice versa. Plus when I connect to media audio and try and switch back to just phone, it doesn't auto connect when I get in the car.

My Rezound didn't seem to have any of these issues.
[Verizon Samsung Galaxy S III] sinman02:
This was the case with my 1st generation galaxy s epic 4g. Looks like Samsung still hasn't recognized this as an issue. The smart developers here ultimately fixed this on my epic but my s3 is still suffering from this... Btw I'm on synergy. I would love for someone smarter than me to figure this out. Please, please....
[Verizon Samsung Galaxy S III] SirKronan:
I don't know who to blame, Samsung or Verizon. I have the Samsung Galaxy Nexus and it does NOT have this issue. Never had that issue, with stock or custom ROMs. A good friend has the SIII on AT&T and it also does NOT have this issue, as the video above demonstrates. He also owns the Galaxy SII, which also does not have this issue. I used to rock a Droid X. At least my Droid X did not have this issue, although I have read reports of other Droid X owners' phones having this problem. My old HTC Eris also didn't have this issue. But, as mentioned above, my Fascinate does have this issue.

It's horrible. I have messaged Samsung, and they have responded that they are looking into it. It's the same response they gave me several weeks ago when I first posted on the support page on Facebook about this issue. I have also called and complained, after which their support tech said she wasn't yet fully trained on the SGS III yet, and they had a special number for me to call, which of course wasn't open at the time.

If a dev can figure this out, he can at least count on a donation from me.

I am sick of this ... I decided to keep this phone despite this issue, because of all the other goodness it brings to the table (especially battery life!! Wow!!) But this is still a horrible issue.
[Verizon Samsung Galaxy S III] CIPuyleart:
I have the same problem - my 2008 Tundra does not have A2DP for audio streaming, but does have BT for phone calls (and works great). On my previous Droid2, I could use the AUX jack for music and the BT for calls no problem. Now, with the S3, if I hook up AUX for music and BT for calls, then when a call comes in the phone keeps the audio out going to the AUX jack while my truck switches to BT for sound. Therefor, I can't hear the other person (but they can hear me) unless I unplug the audio jack.

From what I've found on the net, it seems it's something in the bluetooth settings/drivers in how Samsung has them implemented on the phone, which is not the same as how they are implemented in the Motos and HTCs. I was unaware that other carrier versions and/or certain other Samsung phones (S2, Nexus) did not have this problem.

For now, I've solved it by getting my hands on a car dock for the ATT Infuse 4G, which has the "dock" mode built into the USB connector with both power and audio output. I dock my S3 into this dock and changed the settings to output audio out the dock. Then I plug my AUX cable into the dock and it works like I expected it to from the start.
[Verizon Samsung Galaxy S III] SirKronan:
Does the S3 fit into the dock ok? Any stability problems? And you get proper 3.5 inch output for your car's input, plus your bluetooth call works? I have the same kind of deck in my Freestyle. Installed it myself. It does bluetooth for calls but not A2DP. Thanks for your responses so far! I am willing to buy a dock if it works like that. I would just appreciate any reassurance you could give me that it will work out ok ... :)
[Verizon Samsung Galaxy S III] arkady2k:
but that's a really nice idea that i didn't consider. I would really like to get this thing working and willing to apply any dev fix. what's interesting is that skype calls work fine, yet regular phone calls do not :( i'll give this doc a try.
