You have a flagship device ...Internal memory will be faster than a class 10 SD card ...There is no possible advantage for using Dual partitions ...

when internal memory is used up

For sure, I'm talking about setting up additional memory. 10 gig internal fills up pretty quick once you get a couple email accounts and download your favorite apps. Don't want all that good stuff running slow...right?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] karandpr:
10GB is good enough for a bucket full of apps ....I doubt stuff will be running slow ,even if you use normal a2sd ...

That said ,all of us have internal nand+SD card and the mount points are easier to recognize and manipulate ,

You have a GS4 which has multi partitioned internal SD plus external SD .. dunno if samsung still uses those bml-rfs partitioning (which is a nuisance imo)....

It's usually wise to post in the relevant device sections ....The difference between Samsung-HTC-Sony phones is night and day ....

You have better luck trying the GS4 section who have more experience and the required device ...

My Mini SD Card was reduced in memory size.

Hi guys, I partitioned my Mini SD Card a week ago using this, and I somehow only got 1 GB to appear in the Link2SD storage info from my 32GB SD Card. When I put my card in a few minutes ago, the principal memory was only 1 GB and I couldn't see any other memory. Does that mean I accidentally destroyed the other 31 GB?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] collector0:
Lol now my sd card is not recognized by my phone, on pc works fine. Any advice?

EDIT: Luckily i managed to fix the read on the card.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Doncock:
Sorry if I ask something that is already answered, but the search seems to be offline.

I have two questions.

Firstly, I get a mount script error, mount: invalid argument, ext4 may not be supported on your device. I am using a fairly new kernel, which is built into the Cyanogenmod 10.1.3-p3110 (stable) rom I use fot my samsung galaxy tab 2 7.0 tablet, so I assume ext4 and swapfiles are supported. How can I find out if kernel 3.0.31-CM-gac1803e has ext4(and swapfile)support, because I strike out searching google with samsung gt-p3110 cyanogenmod 10.1.3 ext4 support or googling kernel 3.0.31-CM-gac1803e ext4 support. Also, what can I do to make it work?

Secondly, when I installed swapper 2 on my tablet, I read disturbing comments how swapper 2 bricked a couple devices. Apparantly, swapper 2 delete this one guy's phone's boot sector. Is this something that could happen to my tablet or did this guy just **** up?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] karandpr:
[MENTION=4280841]Doncock[/MENTION]

A.)

cat /proc/filesystems should give you

list of all file systems supported by the kernel

B.)

to check swap support ..

//dump file

dd if=/dev/zero of=/sdcard/a.swap bs=1048576 count=1

//make swap

mkswap /sdcard/a.swap

//enable swap (requires busybox)

swapon /sdcard/a.swap

If there is any error ,there is no support for swap

If not then congrats you have made swap file of 1MB ...feel free to edit the count parameter in the dd command to adjust the swap size

free

Swapper 2's last update was in September 2010 ...that was before Nexus S and just after Nexus One ...

Around that time Android phones came with Nand storage and MMC slot (like the Xperia 2011 series)

nexus S introduced the emmc concept and lack of SD card ...

now some phones' internal storage is at /sdcard and mmc at /sdcard0 or ./sdcard1 ... I have no idea ...it's different manufacturer to manufacturer ..

Swapper 2 is just an interface for that commands I just typed ...

Disk dump ,Make swap and swapon ....

the app is incapable of handling phones whose internal dfile systems is deviant from the original Nand+MMC ...

So yes ...Your tablet can hard brick ....

AFAIK ,samsung uses ext4/ or RFS but on bml partitioning which is different from mtdblocks ....

Also there is no performance boost gained with swap file ...

The method on this thread foregoes the disk dump and uses dedicated partition instead ...

But still swapper is incapable of detecting the partition ....

In worst case , if your boot partition is mmcblk0p3 and swapper detects that it couldn't be mounted and it uses mkswap to format the boot partition then your tablet is hard bricked for sure ...

First of all, thank you for your indepth reply. It got me a bit embarrassed, since I didn't get half of your post and I made me realize I have to learn linux if I continu on the path I set myself upon.

The first part(A) I understood and I have just read up a bit to see what I needed to use a CLI and the linux commands I needed on my tablet. After catting I saw that the kernel installed has ext4 support. Which brings another question, why is Link2SD saying it cannot mount the second partition as ext4? (mount script cannot be created, mount invalid argument)

The second part was a bit harder to understand, because I do not know what bml partitioning or mtdblocks are and what that does. I do know the dd command is somekind of powerful *nix write command, and /mnt/sdcard is the internal sdcard, which I am not going to fiddle with until I understand this completely in fear of bricking my tablet. But if you say that a swapfile is not necesary because it does not speed up my tablet, I will repartition the 32GB sdcard I have and leave the swapfile partition be.

The sdcard is partitioned as follows: 1st 1,28GB linuxswap(kinda big, isnt it?;)), 2nd partion called Data which is 20GB and fat32 and a third 8GB partition called Apps formatted as Ext4. Note, the ext4 partition called Data is the third partition, not the second that Link2SD refers to. Or does the OS not "see" the first linuxswap partition?

I also looked up what the internal nand and mmc slot are called on my tablet. The internal storage is called /mnt/sdcard and the removable sdcard is called /mnt/extSdCard. Correction: the sd card was called extSdCard when it had one 32GB fat partition, but now the OS says the card is blank or it has an unsupported filesystem. I can format it and all data under path storage/sdcard1 will be erased.

[MENTION=4280841]Doncock[/MENTION]

A)Might me Link2SD eroor ....Automated "second" partition solutions suck ...Be it swapper,link2sd ,mount2sd ...but thats because I am a bash geek and like to use my own scripts ...Paste the mount script ...It should be in /etc/init.d ...Also update the busybox ....sometimes the mount command is usually linked to toolbox ,you will need to remove the mount command and symlink the mount command of busybox ....

swap file == swap partition ....Basically swap files or partition are imo useless on android ....There is no benefit of using swap if you have more than 192MB of ram ....which 99% of phones have ...Basically swap will never be used for apps ...

you cant use first partition as swap since the acceptable mount point in init script is only for vfat which is fat32 ...

the only reason we can use a second/third partition for link2sd is that there is no reference to it in init script ...

/mnt/sdcard is the mount point not the device ....

what you need is device/block which is mounted on that mount point ...

e.g.

/dev/block/mmcblk0p1 is mounted on /mnt/sdcard on my phone .....

mount

should give you mount points and block devices ...

Sony Xperia Tipo *Dual* - should I forget swapper?

I am 70 and live in Germany. My English and my knowledge about android and smartphones is rather poor. I use 'Sony Xperia Tipo Dual - ST21i2' with root and Link2SD and want to make this device faster and capable to handle more apps. I use a 32 GB micro-SD class 10 (which might be not the best one - which is a realy good one?) with two partitions: 27,7 GB Fat32 for data and 1,5 GB ext4 for apps. The ext4-partition I created only 1,5 GB because I was reading android would not be able to deal with a biger size than ...?

Running 'MemoryInfo-SwapCheck' gave the following info:

RAM Free: 136,84 MB /404,28 MB

SDCARD Free: 19,99 GB / 27,73 GB

INTERN: Free: 41,81 MB / 2,15 GB

PHONE Free: 87,79 / 753,95 MB

Info: your device kernel is not swap compatible.

Now I would like to change and create a greater partition ext4 or other format.

Probabely I would have to undo the changes with Link2SD and backup all data first. Is this correct? Then delete all partitions and create new ones with MiniTool Partition Wizard.

My device doesn't work with swapper if the info of 'MemoryInfo-SwapCheck' is right. I probabely would have to change the kernel from stock to custom kernel and don't know how to do this. Custom-ROMs seem not to be available besides 'Gimlo' and I don't know how to search for it. Could I get help for that.

Which

swapper-app would be the right one? There are different 'swapper'-apps: https://play.google.com/store/search?q=swapper&c=apps&hl=de ?

Running 'terminal emulator' > cat /proc/filesystems it gave the following info:

nodev sysfs

nodev rootfs

nodev bdev

nodev proc

nodev cgroup

nodev tmpfs

nodev debugfs

nodev sockfs

nodev pipefs

nodev anon_inodefs

nodev configfs

nodev devpts

ext3

ext2

ext4

nodev ramfs

vfat

nodev oprofilefs

How great could I make the ext4-partition at maximum?

Would it be better to use a smaler SD-card? For data I don't need realy much.

Would it for more

speed

be better to use different SD-cards which I could change if needed? On one I could do the apps which I never or nearly never used so I could test them some day - and on the other what I realy use. Could Link2SD deal with such a split?

Which would be a realy fast micro-SD?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] karandpr:
Using Second SD card partition or swap partition wont make phone fast ....It's a myth which has stuck to android ...

Second SD partition helped access to more apps ....At that time the ROM was around 256 MB and Eclair could handle more apps effectively ....

Swap partition helped since the multitasking was not good enough at Android 2.1

It got better and better with Froyo and Gingerbread

The multitasking capabilities are excellent as far as Ice Cream Sandwich is concerned ...Excellent enough to deprecate the use of swap ...

ext4 can handle more than 2GB of data

Yes ...Use Titanium Backup to backup all data ...Then delete all partitions and create new ones ...

I have no idea sadly :/

This is the general sticky in Tipo section

http://xdaforums.com/showthread.php?t=2172652

But Dual Sim variants usually have poor development

Please dont bother with swap ..It's pointless imo ....There is no direct benefit to performance due to sole existence of swap ...

Running 'terminal emulator' > cat /proc/filesystems it gave the following info:

nodev sysfs
nodev rootfs
nodev bdev
nodev proc
nodev cgroup
nodev tmpfs
nodev debugfs
nodev sockfs
nodev pipefs
nodev anon_inodefs
nodev configfs
nodev devpts
ext3
ext2
ext4
nodev ramfs
vfat
nodev oprofilefs

You can use any partition you want ...Just keep the first partition as vfat ....

AFAIK ...Link2SD can relink files but it will be a massive chaos on your phone since android system may not be able to handle missing apps

A class 10 SD card is usually fastest....

--------------------------

Do what I do ...Download apps ...use them ...If you think they are eating space ...Back them up with Titanium backup and then uninstall them ...It's good method

Even so after three years+ of android usage ,I have some 1500 apps in Titanium backup ....and I use 20 of them regularly ....Smartphones can multitask but my brain can't I guess :laugh: :o:angel::cowboy:

Step by step towards creating new partitions on SD

[MENTION=3690061]karandpr[/MENTION]: thank you very much!

I could choose 4-5 GB and would never have to think about space anymore?

Lately I wanted to install offline-language-packages for 'Google Translator' ('Google Übersetzer') and coldn't because of 'lack of space' ('Nicht genügend freier Speicher). 'German' needs more than 100 MB.

Or happened that because of another reason?

I'm using windows 8.1 on my notebook and do not have experience with linux. Lately I installed the driver Paragon ExtFS for Windows. Now it's possible to mount and handle ext4 with windows 8.1.

vfat seems to be a linux speciality.

Should I formate the first partition Fat32 for pictures video, musik, ... so I can use this partition with windows without Paragon ExtFS for Windows - or do I have to take 'vfat' and is vfat available in MiniTool Partition Wizard? Can windows handle vfat?

What difference would it be if I would use Fat32 for the

second

partition too?

Link2SD says 76 apps are on the micro-SD. There seems to be not enough free space on /mnt/sdcard or elsewhere to moove them all back. Besides that my feeling is that some time ago I have 'mooved'/tried to moove system-apps (?) too.

In 'My Apps' play.google also shows 'App2SD & App Manager-Save Space' + 'Easy App2SD (Deutsch)'. I probabely have deinstalled them after installing/using Link2SD - but I might have had used them already and not undone their changes before. Do I have usually before unstalling an app have to undo the changes I made with it?

Link2SD delivers the following info:

Internal space . /data: . . . . . . . .used 665 MB, free 89,43 MB

SD-Card . . . . . . /mnt/sdcard: . used 2,11 GB, free 42,00 MB

Ext. SD . . . . . . .. /mnt/ext_card: used 7,74 GB, free 19,99 GB

SD-Card (2. Partition): . . . . . . . used 620 MB, free 813 MB

System . . . . . . . /system: . . . . . used 373 MB, free 119 MB

Cache . . . . . . . . /cache: . . . . . . used 4,07 MB, free 153 MB

Please tell me step by step what to do before making the backup with 'Titanium Backup'. What do I have to undo before - considering that I'll make the second partition of SD bigger und restore the apps than their.

Till now I have only the free-version of it + 'MyBackup Root' + 'App Backup & Restore'.

Do you restore some apps from time to time to use them and do you deinstall them again after having used?

So I better forget about custom-rom as long as all I want to do with my sony is possible with the os which is installed by sony

Nope....It's something else ...Google translate packs in only 160B to download per language .....Even without an "second" partition ,it's impossible to run out of space ...

Good for health ? Plenty of Vitamin D and stuff :laugh: ...Custom ROMs are over-rated (unless you own a Samsung phone ...then it's a necessity) ...Customizing your own system can be custom rom ...

Both are same actually ..FAT32 is interpreted as vfat in Linux ...vfat/Fat32 is available in Minitool Partition Wizard

umm

Install the app

use right/menu button ...

Click on batch action ...

Then backup all apps + data

Remember :Contacts ,Call logs ,and SMS are not backed up by Titanium backup free ...

It depends ...Like if I like a theme from Cyanogenmod ROMs (which are incompatible with stock ROMs) then I uninstall them on stock roms and install them on CM roms ///

Or I dont even reinstall them since there are newer apps/updates and download them from play store ...

Should I buy 'Titanium Backup PRO Key * root'?

Till now I have only the free-version + 'MyBackup Root' + 'App Backup & Restore'.

For my aged brain: From what Links2SD has done

nothing

has to be undone before considering that I'll delete the second partition of SD and create a bigger one ... and restore some of the apps their again?

Probably not because the path stays the same. But there would stay links in the intern space with no real target ('missing apps').

I understood that android creates 3 diferent things when apps are installed and that Links2SD can mostly moove them all three to micro-SD. Are they all backedup by Titanium or only the app?

Wouldn't it be better

1. backup all

2. de-install what I don't use

3. undo all with Links2SD what it has done

4. deleete + create bigger second SD-Partition

5. restore wanted apps on :confused: inner space

6. moove with Links2SD

all (?)

what is moovable to new second partition?

One more tentativeness:

I could have have 'mooved'/tried to moove system-apps (?) too and forgot it.

Play Store shows in 'My Apps' 'App2SD & App Manager-Save Space' + 'Easy App2SD (Deutsch)'.

I probabely have deinstalled both after installing/using Link2SD - but I might have had used them already and not undone their changes before.

Do I have

generally

before unstalling an app have to undo the changes I made with it?

Yes !

It might "harm" system but do one thing ....Copy everything from second sd card partition and back it up on computer and then copy it back after SD Card repartition ....

castling

My sentence "Links2SD can mostly move them all three to micro-SD'" was incomplete.

Missing was that Links2SD after or before moving 1 or 2 or 3 'parts' of the app creates links to this parts. What you say: "but the script moves to /sd_ext" is what I didn't mention.

Are all these parts of an installed app backed up by Titanium

or only the basic app-.apk

?

Isn't there a conflict between your advice (which I had proposed):

1. backing up all

2. de-installation what is not used

3. undoing with Links2SD of all what it has done

4. deleting + creating bigger second SD-Partition

5. restoring all wanted apps on inner space

6. moving with Links2SD all what is movable to new second partition

and the advice to copy back after SD Card repartition all what I have copied from 'sd-ext4-now' to pc?

Or is this step ment to be done between above 3. and 4. and skipping above 5. and 6. ?

It are only the two words 'defining trail' that I can't translate in a surely way.

I find no translation that hits me 'philosophically'. Is it a self-deprecating/self-depreciating joke?

What other words would transport a similar meaning?

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] karandpr:
Android app is installed in three parts primararily...

/data/app,/data/data,/data/dalvik-cache

/data/app is the main app install

/data/data is the data of apps

/data/dalvik-cache is the dex files (like virtual machine)

Link2SD moves files from /data to /sd-ext and use symbolic links so Android "thinks" App is installed in /data but it is not !

SO if Second SD card partition is formatted or if Link2SD is uninstalled ,Anddroid is incapable of handling such exception

In Native Android a2sd/App2SD, Apps are moved from /data to /sdcard/.android_secure as .asec files

Android knows that the files are moved to /sdcard/android and is capable of handling exception if Sdcard is formatted

In simple words ,Link2SD is a simple but brilliant hack ...and a2sd is complicated workaround but authentic ....

It's almost perfect ...Just you said that you moved some system apps ...That will be nuisance if the changes are not reverted properly ...

It's meant as a last resort ...If you cant restore system apps then backing the second SD card partition becomes necessary...

It's like definition of human ....As humans ,we are the only creatures who spend hours watching funny cat videos ...if Humans were subjected to remote experimentation by aliens then we would be "Creatures amused by moving images of cats " ...
