[Q] A2SD+ Confusion

I'm pretty confused at the moment about the differences between stock froyo a2sd, A2SD+ and 'old A2SD+'. so far from what i'm seeing, using A2SD+ seems to be the best idea, but i'm not sure why this is better, or how to install it as there seem to be tons of different ways.
1. Which one should i use
2. How do you partition your SD card
3. what is this all about ext 2,3,4?
4. Can i set up the partitions using the clockwork mod recovery or rom manager? and how.
Just Sorry if this is repeated else where but i've found it pretty hard to find what i'm looking for (yes even using the search function)

I'd also like to know the answer to this, especially q3
i partitioned my sd card using Rom Manager but i didnt get an option for Ext 2/3/4 when i installed LeeDroid 1.6.
Seems like the new Froyo Roms say Ext 4 is the way to go.

I too would like to know this.
Also, do I need to format into partitions before / during / after flashing a ROM?

I can't partition with ROM Manager at all. It reboots into clockwork recovery mod, and it says
Finding update package Finding update package update package... E:failed to seek in /cache/update.zip (Invalid argument) I:verify_file returned 1 E:signature verification failed Installation aborted.
edit: fixed by nandroid restoring back to 2.1 and trying again

1. A2SD+ is probs the best to use
2. create ext2/3/4 within ROM manager
3. the extension is a portion of your sd card to store your apps i dont know the difference between the 3 but essentially you create the ext2/3/4 so your apps can be forced to the sd card, the froyo apps2sd is designed for apps that are coded to go on the sd card, the Dev of the app has to make it able to run on an sd card. that's why on some apps, you will see the option to move to sd card is shaded out, that is because the Dev has not coded that particular app to run on the sd card
4. see #2
hope this helps

If i create the partitions in Rom Manager, does this create ext 2/3 and 4? what partitions size / swap etc settings should i use? I have a 4gb card so what ever is best really for that?

In ROM Manager if you Select "Partition SD card" in Utilities, you pick the size etc but you dont get to pick Ext 2, 3 or 4, does this matter?

Ok, so here's the deal, in a very longwinded way that should hopefully explain everything and answer ALL questions.
You have an SD card in your phone and, a bit like normal PC Hard Drives, you can "partition" them (split them into two or more sections of different filesystems). Normally, your SD card is just one big FAT32 partition, which is fine for storing your pics, messages, emails, etc.
Now, other then your Phone's SD card, your phone will have its own internal flash memory (or "NAND") storage. Tradditionally with Android, you could only install applications to this NAND storage, you cannot install them onto your SD card. So if you have an empty 32GB SD card, but only 5Mb of internal phone storage, you still wont be able to install many apps, if any at all.
This was done to protect the apps from things like piracy - it's not easy to access the location where apps are installed on your phone's internal storage (normally impossible without root), so you can't for example buy an app, copy it, refund it, then install it again.
Still, this is no good for those of us who like to install lots and lots of apps, legitimately, as we run out of internal storage very quickly.
So Google came up with a way to install apps to the SD card. A folder is created called something like .android_secure and this stores (I believe) encrypted versions of applications, but there's a few catches:
1) Apps aren't automatically stored here, you have to manually "move" them
2) Not all apps are capable of being moved, in fact most apps aren't, the developer needs to update their app and allow it. Some apps aren't and wont be updated and some developers may not want to allow it for whatever reason.
3) Not all app data is moved, most of it is but some data is left on your phone so many people still run out of internal storage quickly.
4) You can force ALL apps to be moved to this area by default, but it breaks incompatible ones - such as Widgets, which are unable to load due to the SD card not being "prepared".
So that's Froyo's version. Before Froyo existed, some very clever people came up with a thing called "Apps2SD". Remember I said that your SD card normally is one big FAT32 partition? Well, Apps2SD works by having your SD card patitioned into TWO filesystems. A normal FAT32 partition for your usual stuff and a secondary "EXT" partition. EXT is just a filesystem, like FAT32 or NTFS, but it's the filesystem used by Android internally. The SD card is normally FAT32 because it's a "universal" filesystem, that just about any machine will be able to read, whereas EXT filesystems are generally Linux only, but I digress.
EXT has several different versions. The most common one you'll see is ext3. The main difference between ext2 and ext3 is "journaling", which is just a fancy way of saying that should an operation (such as copying, writing or reading) be interrupted unexpectedly (say, by you turning your phone off), then no data should be lost or corrupted. You know how when you turn your phone on, it says "preparing SD card"? It takes a few minutes, but what it's actually doing is checking that the FAT32 partition hasn't been damaged, because FAT does NOT have journaling. If you used a computer back in the Windows 98 days, you may remember that lovely blue "Scandisk" screen that had to run every time you didn't shut your computer down correctly - that's the same thing. But then Windows 2000/XP came along with NTFS, which also has journaling, meaning you had less chance of loosing data. But I digress once more.
So you have your SD card partitioned into EXT and FAT32. Generally it doesn't matter if it's ext3 or ext4, but you don't get any real advantage with ext4 over ext3 in this instance. Apps2SD then runs a special script on your phone which "symbolically links" the folder from your phone's internal storage where your apps are normally stored, to the ext partition on your SD card. A symbolic link is a bit like a shortcut for folders, except it's transparent to the OS: In other words, Android doesn't know that when it's installing it's apps to the internal phone storage, it's actually being stored on the SD card. This effectively boosts your internal phone memory from the previous 5mb that you had in my example above, up to whatever size you made the ext partition on your SD card (often 512Mb or 1Gb, but it depends on how many apps you install).
Plus, because it's "journaled", it doesn't need to be "prepared", meaning it's ready to go as soon as the phone starts - so your widgets and apps work immediately (unlike "forced" Froyo Apps2SD, where widgets disappear).
The catch with Apps2SD is that whatever space the ext partition takes up is taken away from the SD card. So if you have a 4Gb card (with something like 3.5Gb of actual storage) and you make a 512Mb ext partition, your SD card will "shrink" to 3Gb. The space isn't actually lost, it's just being used by the ext partition. If you reformat your card, you'll get it back.
Finally, there's a difference between "Apps2SD" and "Apps2SD+". Remember I said that your apps are stored on a special folder inside your Phone's NAND storage? Well, that was a bit of a lie. It's actually stored in TWO places. There's a second area which is called the Davlik Cache. You don't really need to worry about what this is for (Hint: IT's to do with the Java runetime your phone uses to run apps), all you need to know is that apps use it to store data, which also eats up internal phone memory. Apps2SD+ moves davlik cache to the ext partition on your SD card as well, freeing up even more space. Some people believe that this may come at the cost of performance, as the internal NAND memory should be faster than your SD card (Which is why you also get people arguing over which "class" SD card is better for Apps2SD - the logic being that a faster SD card means less impact from this move), but the truth of the matter is that your applications will be running from your Phone's RAM anyway, so performance isn't really impacted at all. Since most apps are only a few hundred Kb's in size, or a couple of MB at the most, it's a non-issue.
Finally, any recent version of Apps2SD/Apps2SD+ should work with an SD card that is or isn't formatted with an ext partition. It'll check for this partition when your phone first boots and if it's not there, just use internal phone storage.
Having an ext partition WITHOUT Apps2SD+ shouldn't cause any issues, either, so you can format your SD card whenever you're ready.
So in summary:
Apps2SD "fakes" your phone's internal memory and puts it all on a hidden section of your SD card.
Apps2SD+ pushes even more content to the SD card, freeing up even more space on the phone itself.
"Froyo" Apps2SD has various limitations that "old" apps2SD does not, but is much easier to handle as it doesn't involve any kind of "partitioning".

@neoKushan Thank you very much. I understand the theory behind it a lot better now. Didn't actually realize EXT was a kind of file system so it makes a lot more sense now. So seemingly Apps2SD/+ is a lot better than the froyo (in certain situations). What is the best method to partition your sd card and install Apps2SD+? I think i've seen that a lot of the ROMS now will install the Apps2SD+ for you if you have partitioned your SD card, so i'm guessing thats the only step i need to take.

As far as I have seen, all of the recoveries out there have a way to partition the SD card. So AmunRA's or ClockworkMOD's (ROM Manager).
My personal preference is ROM Manager as it's very easy to do from the GUI.
Word of Warning, though: Partitioning your SD WILL DELETE ALL DATA ON IT!
Do what I did: Copy the contents of your SD card to your PC, partition the SD card, then copy the contents back.

thanks, that is superb! thanks for taking the time to type it up
this should be posted in the faqs section as it will might stop a lot of these recurring threads
one other question, some ROMs ask you to wipe your Ext partition, where do you do this ?
If i reboot to ClockworkMod Recovery there is a Wipe cache Partition, is this it?
thanks

Top post! Thanks very much.

So if you're using A2SD+, do the "move to phone" and "move to SD card" buttons actually do anything or are they just left there from legacy A2SD? And what does the "Auto" setting of ModInstallLocation actually do? How does it decide whether to install to internal or external?

Move to SD would still work, all it would do is move from the ext partition on the SD card to the FAT32 partition (in the .android_secure folder).

Doh, so essentially they mean the opposite?!
What about the ModInstallLocation app, if you leave that set on Auto, how does it decide where to install things?

Rom Manager asks me to set the partition sizes, then reboots into clockworkmod recovery. No partitioning appears to have been done to the phone though. What am I supposed to do? Or is this a bug?

+1 THX very much to neoKusha! couldn't be explained on a better way!
just one question: ROMmanager makes an ext3 partition, isn't it?

Think about it like this. When using "old" Apps2SD (or Apps2SD+), you're installing your apps to a hidden part of the SD card, a part so hidden that even Android itself doesn't realise it's there, it just thinks it's your phone's internal storage. So when it says "move to SD", it doesn't realise that it's already ON the SD.
As for the ModInstallLocation, I don't use it so I can't comment, but no matter what it picks, it'll always end up on the SD card if you're using Apps2SD, all that changes is which partition it'll end up on. "Internal" storage will be the EXT partition and "SD" will be the .android_secure folder.
However, if you're using Apps2SD, you're better off installing to "internal" storage (As in, the EXT partition) as it's more compatible than Froyo's SD card storage.

I'm not sure, perhaps it's already partitioned. Have you tried doing it from within Clockwork recovery itself?

One last question... When I let ROM Manager create a Ext partition it also ask for the swap setting? What to choose here, I have chosen the default now.

[Q] Internal Memory question

So, I got my device s-off and rooted, was pretty excited when I had those stuff done.
But now,
Internal memory is still an issue, I read on xda like, removing the bundled or stock software comes with the phone won't make the internal memory get increased because those files are stored somewhere else that won't effect the total usable internal memory. Plus removing stock apps will stop using OTA updates.
So is there a trick that I can increase the internal memory of my phone? I already use the default save location setted to sd card, and moving apps to sd but it always leaves some files at internal memory.
I read somewhere like, I can make phone use my sd card's some part as internal memory, I saw a rom offering that but except that is there any program offering this without flashing rom?
And I have some knowledge about Linux, so I was wondering do I have a chance to use symlink command (symbolic link) to link my internal memory to sd card ?

Best way is to use a ROM with Darktremor Apps2SD preinstalled. I don't know whether it will work if you install it now.
The best alternative, in my opinion, is to format a partition of your SD card to ext3 with this guide and then use Link2SD.The partition can be as big as you want, but I believe that 500 MB should be enough.
It will earn you some space but not as much as the Darktremor Apps2SD will.

Thanks for the answer, I used the guide and Link2SD, but i am a bit confused here, I also use apps 2 sd program,
So for using less possible internal memory of my phone,
Should I install apps to phone memory and then link to sd card with link2sd
or
Install app in sd card (or move it with link2sd to sd card) then link?
Right now one of apps shown as Linked -> SD card. So is this the best scenario?
Because when I choose move to SD in Apps 2 SD, Link2SD says move to SD also, so it kinda like they conflict

To tell you the truth I'm not completely sure for what is better, but what I did was to first link all of them (application, dalvik & library if possible) and then move them to sd card with App2SD. I think there was a slight difference to the free space but nothing noticeable. Sorry, but I'm no expert, so everything I did was by trial and error!

Questions about Using Link2SD (and tips on moving apps to external storage)

Hi there,
Have previously rooted my Samsung Galaxy Tab S using a method that was provided to me in a previous thread I had created.
I have started to wonder recently about the benefits (and reprecussions) of moving apps to external storage (i.e. a micro SD card) using the app Link2SD or similar apps. Also, I am not sure what may happen since I inserted the microSD before I rooted the device, and have been using it for storing downloaded files, large video files etc.
This being said, I have the following questions about using an app (such as Link2SD) to move the application data as well as applications themselves to the external storage:
1) Will this drastically impact the performance of the tablet? (i.e. is there a noticeable slowdown, say, when playing games that are moved onto the SD card)?
2) I already have stuff on the micro SD card (moved apps and other personal media I put there myself) . By removing it (safely or unsafely) and then putting it back later, will this "break" some of the apps? I had previously moved some applications to the SD card using the Application Manager in the settings page of the tablet. ....... I am asking this because I am aware that the microSD card may need to be removed to create a 2nd, linux-based partition (such as ext2, ext3 or ext4) so that the Link2SD app can move applications and application data...
3) Since I have already moved some apps onto the microSD card using the tablet's built-in Application Manager (under Settings > Applications), will this create issues if I remove the micro SD card?
4) I have read some stuff saying that the size of the 2nd (linux-based) partition cannot be larger than a certain size (this "certain size" varies based on the articles I run into). Is there a size limit for the 2nd partition that is created on the tablet?
5) Any tips on how to get the microSD formatted to ext4, and is there a preferred format for the 2nd partition? In Linux systems I have set up before, usually the user directories are formatted to ext4, so that's what I was going to do unless there is a good reason to use a different format. Am planning to do the partitioning using gparted in windows
Thanks so much in advance, and sorry for all the questions.....

Any help would be appreciated...

Issues moving certain apps to External SD

I have a LG G3 running stock M 6.0
I'm trying to increase my 16GB flash size or at least move my big apps to my external SD.
I did OK with Spotify and some others, but few others (like some games) are not moving their data to my external sd.
I have problems with those apps detecting my Internal Storage as my external SD card due to the fact that the Android mounts the internal storage in
/sdcard/
linked to some other folder
/storage/emulated/0
while my real external SD card is actually mounted on
/storage/7FB0-1DEE/
What on the earth is this thing calling my internal storage, sdcard, and my external sdcard to some strange mounted folder with a weird code that of course my apps have no idea wth is that...
Any ideas how to workaround that? Any guidelines will be very much appreciate it.

PD. I don't want to use any App2SD or FolderMount rooted 3rd parties to create logical links/shortcuts and "pretent" or make thing the app the files are on the internal storage, when they are on the external sd. That thing works OK. I rooted my stock FW and tested it that way, but I dont want my phone to have root access.
PD2. I installed RR582-Nougat711 to test this Ext SD adoption (which is not available on G3 Stock M 6.0). It sort of worked OK but I lost my ext sdcard when connecting it to my PC. I'm not willing to make my external sd part of the internal storage anymore. That think is awkward, encrypting my card and losing portability to MTP transfer.

Not enough storage space

I recently bought a Redmi Note 7 and installed a SD card for extra storage. The system shows that I have the extra storage but when I try to download an app I get a storage error. How do I install and move my installed apps to the SD card. This seems like a very serious flaw in the design.

Same problem, any solution?
I'm having the same problem with my Redmi 7, have you found any solution to it? I can't find any way of moving apps and content to my external SD card. it is getting a bit ridiculous now at this stage.

Install DiskUsage from play store, and see what is taking up space

there are two ways to use SD card to save app data
1. enable adaptive storage (on our device it has to be enabled through adb, google it); when using this option sd card won't be usable on other devices
2. partition your sd card, basically you have to create a second SD card partition where you can save your data, then you can use apps like app2sd or link2sd to move apps to SD card
