USB storage? Internal? And sd card - Galaxy S II Q&A, Help & Troubleshooting

Hi
I have in a long time wondering what USB storage are used for ,and which apps are being installed there and were apps are moved when moving to the as card.
and why is there not just one big storage and the sd card. I think it is a bit confusing
I have also looked in storage in settings and then under USB storage and other files, the external sd card is shown as something which takes space,why that?

[Q] usbStorage and external_SD

What is the difference between this two stock folders? And where is the 16 GB external stock memory located?
The external SD is the micro SD card you add to the phone .
USB storage is external USB storage .
Stock memory is inbuilt .

I haven't added any micro SD to my phone still I can save files to my external SD folder and it says it has 16 GB of memory.
I can also save files to the usbStorage folder.

You can because they are using your internal storage. If there is no external card, the external_sd folder is just a mount point.

[Q] wasting space sdcard & externalSDcard

Hello.
I just bought a MicroSD, and saw on ESExplorer that the phone mounts the externalSD inside the sdcard folder /sdcard/external_sd
That way, it thinks I only have 11.5Gb available and everything I put inside my external_sd actually fills the internal memory.
I should have 11.5+8=19.5 but I don't.
Any way to fix this?
Thanks a lot!
I can't believe no one has a Galaxy S2 with an external Sd card!

Settings menu/storage and did you format it there first? Or do you use Kies and what is it using for sending stuff to your memory (Internal or External First?)
In settings/storage do you see both cards? In mine I can see SD card 29.81gb & USB storage 11.5gb.
Yes it shows the external card folder in the internal file explorer. It doesn't mean files are saved on the internal card. It was also like that on the S1 as well.
When you connect to PC in USB mode the PC will show both cards separately.

external_sd is just the mount point. You will only have ~12gb available on your internal memory because the phone uses some memory for the OS. I only have 7.4gb usable on my 8gb external sd. The available memory is always smaller than advertised

Phone is confused between USB storage and my SD card

I just upgraded to a Samsung Galaxy Ace 2, after using my old Xperia for 2 years. I love the phone apart from one really annoying problem and that's the phone seems to be confused between its USB Storage and SD card.
The USB storage is 1.10 GB and seems to be the default partition for large app data that you have to download like maps for gps and game files for hd games, so it runs out very quickly.
It is located at /sdcard
I have a 32GB SD card, where I ideally want this application data to live so I can have more apps.
It is located at /sdcard/external_sd.
I tried editing vold.fstab to swap internal/external sds to no avail and had to restore the original.
Task Manager > Storage is showing my storage information correctly but apps such as App to SD are treating my USB storage like my SD card. When these apps download their additional data it goes to my USB storage. In the applications menu "On SD Card" displays apps on my USB storage.
I'm looking for either:
A way to move the apps and appdata from USB storage to my SD card. I know this can be done in a file manger but then the apps wont be able to find their data.
A way for these apps to save additional data to my SD Card NOT my USB storage.
A way to get the phone to realise my USB storage is NOT my SD Card.
A way to completely disable USB storage and use my SD card as its primary storage function.
A working vold.fstab modification for the Samsung Galaxy Ace GT-i8160
Many thanks
I'm actually trying to find a way to get my games to install their data on my external SD card. The USB storage is actually an internal SD card inside your phone so its not actually getting confused. The only way for apps to save their data to your external SD card is for the developer to make it an option in the ROM. There's a mod for Gameloft games that allows it to install its data onto your external SD card if that helps. Just Google it.

I can only think of using a usb cable and manually storing in Internal SD Card.
Is it possible to partition the internal usb storage so as to use it as an external sd card ? Or can we change the default installation location of apps to Internal usb storage.
Please note that I am not using an external sd card. So i would like to move/install apps to internal usb storage. I have also read that many android phones have this option "Move to usb storage" under application manager.

Try taking out the data from the sd card, removing the sd card from the phone, and moving that data to the Internal SD Card. I don't think Shostock3 has that option.
I have all my apps and data installed in internal storage (i.e. 2 GB storage). But unable to move them to usb storage. I haven't mounted any external sd card. The storage is as follows :
Internal storage - 2 gb which is almost full because of apps
USB storage - 11 GB of which 9 GB
is occupied with audio, video and other files.
I seek to use this free space of usb storage for installing apps.
Try the app Move2SD.

None of the apps allow moving of apps to usb storage. They could only move them to external sdcard.

I found the solution for you. Try going into applications, click the app you wanna move, and click Move to SD Card. If it moves to the external card, remove that then try. It works for me.
Without external sd card mounted, when i click move to sd card; it says "not enough storage space". But with external sd card mounted, I am able to move apps only to external sd card and not usb storage.

That's imo going to be your best bet. Just manually move your apps to your usb storage through your pc.
Also, if you have ES file explorer, have you tried to use it to move your files to the usb storage?
Thanks for your replies. I have mounted an external sd card and using link2sd to move apps to it. One thing I noticed that with sd card mounted, when I move apps to external sd card, some part of the app moves to the usb storage and also the app size increases after doing so. However, still there is no direct way of moving/installing apps to usb storage without an external sd card.

free up storage space
A simple way to free up storage space is by deleting all the log files in the device memory. Just dial *#9900# on your phone and select option 2 “Delete dumpstate/logcat” in the prompted menu. It's not necessary to root your phone either. That’s it!

FYI, this code only works on Samsung-based roms; it won't work on AOSP roms.
