[Q] Internal-External Memory Swap: useful or not?

Hi
I have a Samsung Galaxy W, and you know that this device has such a little memory for apps and games.
I bought a 16 gb class 10 external sd and I was wonder if the memory swap mod could be a really useful operation.
I'm not usual to install lots of applications and games, (I really use only social apps) however sometimes I like to play some heavy-data games. So I need a help: do you suggest me to keep the sd as a default external memory, maybe trying to move the heavier apps in this external space with link2sd and other stuff, or it would be better to make the swap and then make the sd recognized as internal memory?
I read that sometimes the swap operation causes lags and some other stuff, so I need your opinions and suggests.
Thanks in advice

Some custom ROMs automatically swap /sdcard/ with /sdcard/external_sd/
You could try that, it's a great solution IMHO.
Did you try "GL to SD(root)"? Download it from the market... It just mount the external SD as the sdcard, but temporarily. And it also moves game data to external SD.
Sent from my GT-I8150 using XDA on CyanogenMod 9

Also bugs me as well. I just bought 32gb class 10 card and i am using cow bionic 2 rom. But i already changed the vold.fstab folder back to stock. I would be the same not a heavy app storer. If i dont use the app any more i delete it.
But supposedly if you have a class 10 card you should not experience any lag if you have the swap done?? How true this is i dont know

maybe i'll find this useful for heavy data games like generation of chaos or other apps/games that install themselves on the internal storage and not on the sd card, other than that, i seriously don't know what other advantage it can provide

Of course, swapping is a good solution for huge games data storing on external sd and u own a class 10 sd card which is fast enough for swapping. However, this may cause problem when u want to remove sd card as most of the apps are stored on it.
GL to sd is a better solution to me personally. I wrote a similar script instead of using GL to sd. This mounts certain paths to ur external sd card while keeping other important apps such as launcher, theme, widgets, on the internal sd.

Care to explain about the script you wrote. Also whats GL?? I wouldnt use any big games so no point in me swapping. But if any roms i flash to the phone has this done ill not bother changing it back to stock. Also is class 10 not the highest micro sd card you can get??

Yes, class 10 is the fastest writing speed for MicroSD at this moment.
I used script manager to create a script for mounting and give it SU and set it on boot. It is very simple.
Create a new script file and type the following:
(I used the Android folder as example)
Code:
mount -o bind sdcard/external_sd/Android sdcard/Android
This is for gameloft
Code:
mount -o bind sdcard/external_sd/gameloft sdcard/gameloft
After creating these, u need to cut the files in Android or gameloft from internal sdcard and paste them to the new location on external sd. Leave the original folders empty.
Remember to set them "boot" and "su".
enjoy
Edit: if u download any other games that stores its data in Android folder, it will automatically move to ur external sd card as the script has mounted the path to external sd since every boot.

But, in a swap situation, on the Wonder, Apps are not moved to External SD Card........
without swap they are moved to /sdcard/external_sd/.android_secure folder
with swap, moved Apps should be on re-mapped internal SD, so removing SD Card should not have any effect on Apps...
of course App Data should be on External [Removable] SD Card...re-mapped as /sdcard
It seems to me, for game players, Game Loft, etc.....Gl to SD is the ideal solution....****see also EDIT below****
Video for Wonder Here:
****EDIT: Just to say, yewsiong script looks good for gamers, etc.....****

It's pretty useful if you're an avid gamer. Some games usually reach 400mb+. But if not, you could still use it for storing music and videos.

I think he meant without swapping, external sd can still be used as data, music, pics, etc. storage.

Go for it!
IMHO I see no cons whatsoever in performing the SD Card swap, just pros. I got my 32Gb Class 10 just for the swap... Check my signature links to see what I've done to my SGW...

Hi,
I followed the method outlined in your signature (http://latgale.co.uk/?p=70) and now I can see about 15GB (I have a 16GB class 10 SD) available for apps on SD.
However, when I try to move an app to the SD by using App2SD, the app doesn't go to the 15GB partition. How do you do?
Thanks a lot.

Yeah... This is something I haven't found a solution for. Whenever you try to move an app, it goes to the USB Storage. Since we swapped memories, the app will be moved to the 1.7GB memory. For me it'd be great to have everything in the Micro SD card, the 1.7 GB memory is useless to me...

Yeah, that's a real pity! :crying:
I wonder what's the point of doing so, if the memory available for the apps still remains the 1,7GB partition... why swapping partitions then?
Do you have any idea if there is any ROM that lets you install apps in the "bigger partition" (the 14,3 GB according to the example above) or are you aware of any other possible solution?
Thanks.

But, as I said before here ad nauseam, the External Physical SD Card is where Apps moved by App2SD are designed to go......so before doing a vold.fstab mount point swap, ppl should ask themselves.......
Do I really need a gigantic Internal USB Storage at [/mnt/sdcard], for what reason do I need this??
I think myself, that this is only useful for those who require to have Storage requirements for certain Games and GPS Maps Storage, etc, which do not have a built-in ability to store data on the External Physical SD Card [/mount/sdcard/external_sd]....but there are other ways to achieve this!!!

Yep, that's exactly what I would like to have!
I bought a 16GB card to install many maps and games, but I quickly ran out of memory so I cannot add anymore apps (without removing already installed apps of course).
That's why I would like to use my SD card for apps - if possible of course!
And it's a pity I have 15GB free (for what? Just my music/video/pictures?) and I cannot use this space for apps.
What are the other ways to achieve this you mentioned?
It'd be really helpful!

[Q] SD Card Unexpectedly Removed / Virtual SD Card

Hi all. I'm currently running CM7.2 Stable with radio .1111 (used to be the newer .0320) and I can't get any SD card to mount for an extended period of time in recovery, Android, or fastboot. I'm thinking the memory card reader is either loose on the motherboard of the phone or is starting to go. Unfortunately this means that I can no longer take pictures and use apps that require the SD card. Does anyone know if it's possible to use the internal memory (such as /data or /system) as a "Virtual" SD card? Any search I've done on google hasn't turned up much. I'm hoping to get a system dev's; or anyone else with experience; input on this. Thanks.

You might want to try a different recovery or rom to see if that still happens. (although it is probably a hardware issue, it's good to make sure) Do you still have warranty?

I'm almost 100% positive that it's hardware, but I also don't have a safe / reliable way of flashing a different rom/recovery anyway because of the chance of the SD disappearing during a flash. Also when searching for PG32IMG.zip, fastboot hangs for a little bit when trying to access the SD card so that helped me verify that it's hardware. Unfortunately I got the screen digitizer replaced on my phone by a 3rd party so my warranty is void, it's also been more than a year since I bought the phone (pretty sure the warranty is just for a year).

Maybe you could try a different sd card.
Or maybe you could take this as a hint to upgrade
And AFAIK there is no way to seperate the internal memory, as some roms need all of it/most of it. I know you could do it the other way around, partitioning an SD card to trick the phone into thinking part of the sd card was phone memory.

I mentioned in my first post that any SD card won't work. I would like to upgrade to a Nexus phone (good CM support) but I'm not due for one until February. The data partition is pretty open in terms of space, especially if you don't have a lot of apps for it. I tried creating a 300MB .img file in /data and mounting it to /sdcard but that didn't work. I'd like for a ROM developer or someone who has in-depth knowledge about the storage systems to hopefully answer. Dalingrin and other developers were able to use the HP Touchpad's internal storage as an SD card, I'd like to do the same.

[Q] is it possible to extend the internal memory

my elder brother just purchased a new 8s.
actually he is facing a problem which everyone on this forum face.
So, the question is it possible to replace the internal memory with 8GB or 16 or etc.. as what we already done on HD7..?

probably. but i dont wanna try it yet

i already saw a guy disassembling the device on youtube. i will try to find it and send him a message. if htc still uses micro sd as internal memory, that's mean we can extend the internal memory and solve the issue.

any update on post above ?

"The microSD card slot is soldered into the motherboard."

Crazy Idea: Could be possible to use the SD Card memory as internal memory making some mod on a custom 8s rom?

pls extend it it makes me crazy..... cant install 1 good game....

I`ve asked the guys from "Rounded" who made this repair tutorial.They said that this phone does not have a microsd slot for the internal memory.But i am still optimist and believe that this will be fixed by the MS guys.

[Q] Annoying Memory Issue on worlds Best phone.

Hi there,
Its my first post so please ignore if I am repeating this querry.
BTW I am using my note II and its been great experince so far.
What I want to know is that:-
1.I found out that I cannot have games more than the devices memory as internal memory gets full and I have to delete some game every time when i am installing a new one, the more pain is that in this thing i also have to lose my all saved data.
2. Cant receive files to SD card when ever internal memory is full,although i have 32 gb ext card totally free, It's very heartbreaking to face this issue on a best phone.
Please tell me the best possible solution to these to issues. I'll be very thankfull to you all.
Other details:
I am not rooted and also don't want to do it.

Unfortunately for you rooting is the only solution if you want to move apps or install them on your external memory directly. Just in case you decide to finally root your phone you can use apps like directorybind or apps2sd... They work perfectly fine as long as you follow exact instructions.

Hi bushako,thanks for helping.
kindly let me know if i root, am I i able to retain my saved game data also? and if i want to play the same game after deleting it can i get the same working with saves?
also let me know other best apps for this whole thing.

Yes rooting will not format or erase your apps/saved games. It's just a matter of letting certain apps have access to your root directory which by default is disabled, there are many threads on instructions on safely rooting your phone. As for retaining the saved game after deleting the app I'm not sure but I think the only way is to manually access the files where the saved games are stored and backing them up. Another method I would choose is by using Titanium Backup app, but it will require rooting. It will allow you to backup all or individual games onto the external sd card including there data. So that you can restore the game with the saved data anytime in the future.

Best thing is to root and use the mod to switch your internal sd and external sd... so the phone reads your 32gb ext sd card as internal and installs all your games on it with the data

@ KyleDevlin12....dont use that stupid apps2sd..it doesnt work dude....the best and ONLY solution is use directory bind...soo easy to use...in 3 steps your games are in your external memory...Or another method...if you want to use the mod which change the external into internal memory ...than u have to buy a 64 gb sd card..otherwise it isnt worth to use this mod.
So from my own experience ....Directory bind is the king in this case.
hope i helped you out.

Not quoting many post, just to add
-Root device
-Root won't erase anything (though always prefer backup), even rooting only can backup game level etc.
-Directory bind i recommend. This also survice your data while factory reset. Read This

[Q] SD Card problems

Hey everyone,
I've been looking everywhere to get some help with a problem I have with my 32GB SD card.
I'm using an Xperia Play (R800) rooted, unblocked and bloteware removed. Whenever I try to move files, I use one of 2 methods:
1) moving files by connecting the phone to my PC via USB cable and dragging files
2) unmounting the SD card from the phone and use a card reader to move files
In both cases, no matter how I try or how I move the files, eventually the phone will either freeze / freeze + reset / reset / or everything combined several times. Once the system boots up again, it restarts itself several times while trying to read the memory card.
This is really frustrating because it happens to me for the past 4 months, ever since I bought the phone and tried working on it. No matter what I try to do, I always end up with this problem, which eventually leads my SD card to randomly delete files. This includes music, transferred PSX games and such. It's really bugging me, and I really need some help.
If anyone can help me out, I'd deeply appreciate it.
Thanks a bunch in advance
NOTE:
The card was later formatted to 2 partitions: FAT32 and EXT2. This DID NOT help, so re-partitioning my card won't help. Think of something else.

Repartioning your sdcard over and over can result to data loss. Why did you have 2 partitions? You should only be using FAT32 as your primary partion.

I only did that once, and it doesn't have anything to do with the data loss as this happened before I partitioned the SD card. I have 2 partitions for Link2SD app. And even if I do have FAT32 as my primary partition, it still deletes my files at random...

I have 2 partitions for same reason as you Link2SD! That should not be a problem.
Couple of questions
(1) Is this a new SD card and have you used the card before on other phones (Could be a fault with card try different SD card)
(2)Have you been on the same rom since this problem started (If yes i would try a different rom could be a software problem.)
I would try these options to narrow down what the problem is seems like you have tried all the partition and formatting options already :fingers-crossed:

To answer your questions:
1) This SD card has not been used on other phones since this is my FIRST smartphone (took me a while to move to the next step )
2) I never use roms, only the default stock rom.
I find it hard to believe that the SD card is the problem, but what do you think?

I think only way to know if SD card is to blame is try another one,there are apps on Google Play that can test SD card but I don't know how reliable these are.Also you said you deleted bloatware did you delete something you should not have?It would be good if you could try another card then you would know for sure a smaller SD card just to test?

Well, oddly enough the problem WAS the SD card all along! I've been trying a new SD card for the past week and everything went smoothly.
Funny, but the solution was only to replace my SD card.
With that in mind, I'm changing my question. I guess there have been many posts about it, but I'm going to ask this anyway:
What would be the best SD card for the Xperia Play? The bad one I used recently was a SanDisk 32 GB Micro SD card, and the one I'm using now is a small sized 8 GB.
Can anyone help me out on this one?

The best sdcard for the xperia play is a Sandisk class 4 or 6 sd card. Preferably stick with the class 4.
