Hello everyone,
I just reed this two post about increasing the internal memory of an android device using micro sd card.

Did anybody tried to do this on a g tablet, does it drain your battery faster or anything ?

There are 2 different techniques being discussed in those posts:
The first, is using a swap file to increase the amount of virtual RAM. That technique (and hence those apps) will work only on kernels which are compiled to do swapping. Some gTablet kernels have this enabled (2.6.39.x and 3.1.10.x) and some don't (2.6.32.x). On the kernels which don't have swapping enabled at compile-time, you can recompile the kernel with swapping enabled, but, in any case swapping to disk is of questionable usefulness because of the interaction with the Android low memory killer feature in the kernel. In most cases, the low memory killer will start killing apps before any apps can be swapped out to disk.
The second technique discussed is the "apps to SD" feature where a separate extn partition is created on an external SD card which is then used to complement the /data partition. On the gTablet, because we have a large 16GB internal SD card, it is simpler to just resize the /data partition instead of using hacks like apps2SD or link2SD which are meant for old smartphones and which are not guaranteed to work on all ROMs.

Hey guys! I found some videos on YouTube and learned something about partitioning of the sdcard.And I believe that we need to choose some ext. partition of 128,256 or 512mb and do some swapping things.Will that actually increase the internal space on our phone? Can someone show me a thread regarding this or give me a detailed explanation??? Thanks!
Some ROMs have this feature implemented. (Void, megatron, etc) Nothing new...

So will it increase internal storage space???
It doesn't increase it. The apps will install on sd card and you will have more free space on internal storage.

Is it the same as Apps2sd?
Yes. App2sd needs that ext partition. Otherwise the phone simply uses the entire memory card with FAT filesystem.

Do you mean the original 2GB SD has ext partition? I think there is only one partition although I can use apps-to-sd in my P500. What is the real benefit by using more than one partition?
Yeah I would like to know that too!

No, rikux, the original card only has FAT partition.
EXT type partition should be created only if you plan to use app2sd with a custom ROM.
In case things are not clear, App2SD is a feature that moves installed applications onto the memory card. There are two ways of using it:
1. Simple install of the app from the market. Now you got yourself a nice little batch mover from internal memory to the card. It can not move apps installed as services and widgets. You could move the apps yourself, but you can only do it one by one - so there's where Apps2SD comes in handy because it lets you do it all at once. All clear so far, OK?
2. A more sophisticated use of this feature, actually called "a2sd" and used in the custom ROMs. What it does is tricking the phone into believing it has more internal memory available. But all this extra space must come from somewhere, right? Thus, this space it's taken from the memory card under the appearance of an EXT partition. Why EXT, I don't know - probably in order not to confuse the phone with two FAT partitions. Now, when you install an application, the app goes to the internal memory but physically it's hosted on the SD card... get it? No more "moving to SD card" necessary, because now if you choose to MOVE an app from the "internal memory" to the "SD card", what you're actually doing is moving it from the EXT partition to the FAT partition. Moreover, now even service apps and widgets go to the SD card, and everything happens automatically.
rikux, you're falling in the first case above.
AsherChua, what you've seen on Youtube fits in the second case above.
I really hope you understand now the differences, and the utility.
Masteryx thanks very much for the good explanation.
As I am not going to use any custom ROM, the Froyo 2.2 inbuild capability to install2SD one by one is enough for me. So it seems like I don't need any more partitions.
The question still remains, are these "App2SD" and "a2SD" somehow more efficient than the standart Froyo apps2sd, which cannot install all apps to sd and if it can then only a part of app is in sd. I assume methode 1. and 2. can install all apps to sd.
Still one question as my 2GB original SD is quite full allready. Is it OK to copy all from the original SD to a bigger SD with PC card reader? Can the new SD be formatted in PC and is FAT32 OK?
Method 1 can install on the card only the apps that Froyo allows, not all of them. Method 2 installs all of them on the card.
About the new card: yes, it will work just fine. Just make sure you copy everything, including the hidden files and folders.
I suggest formatting the new card in the phone. Let it "decide" what kind of FAT system should be used. I know that FAT32 is a bit more reliable, but the phone manual clearly states that the card should use FAT16 (aka FAT) file system. I'm pretty sure both will work exactly the same, so do as you please.
Thanks masteryx for the brilliant answer! One question though,I'm using megatron and it has apps2sd 'preinstalled' in that rom. So can I say that I have case 2 enabled too?

Yes, you do.
Right thanks!
Hi all,
Does anyone know if it is possible to make a swap file on the internal SD card?
I have a 32GB internal but a class 2 16 external so this is my only option.
will it shoten battery life or general phone's memory/ productivity life?
anyone tried it before?
thanks!

If you want to have a swap file (swap.swp) this could possibly corrupt your fat partition. This is based on my own personal experience of course. I recommend use a swap partition honestly.
Just imagine mounting your sdcard to your computer to transfer files while your phone is still attempting to write to /sdcard/swap.swp. This can theoritically cause problems. And you don't want problems on your sdcard. A seperate partition is the safest way to go. But again... just my opinion.
NB: This mod will only work if the kernel you use has swap support built in !
Note that if you are using a rom based on Cyanogen's kernel it is NOT recommended to use swap at all. It will slow down your phone causing more problems than what it's worth. ('Swap grave' is how he put it.)

Are you sure this is for the internal SD card?
BUMP...
Hi guys I am new to android and I got myself a Micromax A110 running on android ics with 2 gb of internal SD card memory...
As you guys can figure, the internal memory just isn't enough for installing heavy games and storing and downloading large videos and music, so I added a 32 gb external micro SD card.. the card shows in my file manager and its contents are accessible, most apps like ttpod, ttorrent, vlc, chrome etc don't detect my external card. They only access the contents of my internal SD card, download to it.. I can't set the default directory to the external card...
When I installed nfs most wanted to my phone, it asked me to free up data in my SD card or insert another one as there was no space left due to obvious reasons of my internal SD card being filled with other apps.. I uninstalled and reinstalled it after setting the default storage location to the external storage... I found that the game installed in the internal storage this time and on startup, it gave the same message..
Is it a common problem or a limitation to the OS? Is there a work around for this? If so how? Does my phone needs to be rooted for the purpose? Please help as the problem is getting annoying.. my external card is lying almost empty...
Thanks in advance,
Extremely sorry for the long post...

It's because Google made the stupid decision, starting with Honeycomb (which is why the Motorola Xoom, the first Honeycomb device needed an update to enable use of it's MicroSD card slot) to merge the /data/ and /sdcard/ partitions. What that means is that the SD card becomes a virtual space (a folder, in fact) located in the same place where all your apps are stored. Why is it stupid? If you have a phone that actually has a MicroSD card slot, like yours or the Galaxy S III, the MicroSD card becomes a different "folder" (something like /sdext/, which stands for either extension or external). Only apps that specifically are programmed to look for that mount point/folder will be able to use it. Most music/video/picture players/viewers can, because it makes sense to automatically program to do that. But with large games, like you said, NFS Most Wanted (which I also have), it sucks because the game is like 2GB.
My Galaxy S3 has 16GB internal and a 32GB card. I'm forced to use the internal storage only for large games because they don't see the memory card. It sucks. The good thing about merging /data/ and /sdcard/ is that it simplifies things, like on the iPhone where your space is your space, no matter how you use it. It used to be that you had like 1GB or 2GB for apps (the APK files only, not the files that games download for example) (which the HTC One X does, but still only uses internal storage because there's no card slot), and the rest went to your MicroSD card slot. Now it's all to internal storage because your internal storage IS your MicroSD card slot at system level.

Hey man! Thanks for the reply....
Can you tell me how to work out a solution for this?
Is directory bind or fstab file hack the only solution?
Is it possible to overcome this without root?
And some apps do detect my Micro SD card... It is in the directory mnt/sdcard2
Please post questions one time only and in the proper Q&A section.

Hello,
What is the easiest way to expand the usable memory for apps on an Android KitKat phone which is rooted? I have seen many apps and solutions to this. Link2SD looks to be the simplest. I want to enable the device to use the external SD card to store apps and data to. The phone I have, LG L70 D321 has 2GB of phone storage and 2GB of internal RAM (ridiculous). I have a 16GB external SD card which I want to load the apps onto since the other space is already exhausted.
The solution should be transparent to the end user, meaning that when they install a new app, it simply gets installed to the SD card without having to do anything extra like assigning paths or anything.
Thanks everyone.
There are a few apps that will install them on sd cards but be warned it will hurt performance and may cause issues. Also no widgets for anything on sd card.
Hi people. I have aquestion about Adoptable Storage in MM.
Pre:
My girlfriend's phone's recentlly receive MM firmware and now I can't move apps to SD unless it's in Internal storage mode but I don't like this mode because it reduces portability of the card and difficults to copy media files like videos and pictures.
I was wondering about downgrade to LP, but then I read a tuto about using Link2SD to divide the microSD and link apps to internal partition, but I don't like the concept of "link" apps data using a third party app.
So looking for more info I came across this article Android 6 Semi-adopted storage about using ADB to divide the SD in both internal and external storage. I find this method more apropiated for my case but I have some questions.
Q:
Any of you uses this method for microSD? What about performance?
If I divide my card this way, can I use it in my computer to copy files in external partition? And what if I change my Android device? Could it detect and use external partition? How do I use internal partition in this device?
The most important question for me is about portability. Sorry for my english.
Greetings.
