Difference between "Device memory" and "USB storage". - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone,
Whats is the difference between device memory and USB storage?
As far as i see all the apps installed on the Device memory and all the photos and other files are located on the USB storage.
I had "insufficient storage available" problem which I fixed by uninstalling apps and that cleared some space on "Device memory" which has only p1.97GB of space, and on the other hand "USB storage" has 11.50GB of sace.
Is there a way to install apps on the USB storage?
I tried apps2SD but i see its only for external SD card.
Thanks in advance.

Device memory is for your apps and system etc. Usb memory is the mass storage for all your pics and music and for whatever else your apps might need space for.
They are basically partitions and as far as I know, there is no (safe) way to change them.
Btw apps2sd is for moving apply data to an external memory card.

Device Memory is referring to the ~2GB system storage partition on the device, which is part of the total 16GB of internal storage. Another ~12GB is taken up by what's being referred to as USB Storage, and refers to another partition of the 16GB of internal storage. If you have an SD card, that'll be referred to as the External SD Card.
Your system storage ("Device Memory") is located at root /
USB Storage is located at /sdcard
If you have an SD card in your device, it'll be located at /emmc/
Please do note though that these locations may/probably do change between ROMs, and I only know for certain that these correct within CyanogenMod 9.

Just FYI, external SD at /emmc is for AOSP/AOKP ROMs.
For Sammy stock ROMs, external SD will be at /mnt/sdcard/external_sd. (This is Samsung's brilliance. Not sure why they did this...)

Ah, thanks for that! If I'd given it more thought, I probably would have figured that out. But alas, brain is obviously not functioning. Cheers.

Why is it that when I take the option to move some apps that can be moved from device storage to USB storage I don't see the used space going any higher? please check out this image for an example. the figures don't seem to add up with the used figure against the apps with the ticks that have been moved to USB storage.

I still can't find an answer to issue raised here. How can I use USB storage instead of device memory?

[Q] external_sd folder And external SD card

Hi all!
I have recently brought an 16GB External SD card for my SGSII, to store my Titanium Backups. I found the external_sd folder in the internal sd card, and thought that it was the External SD card, so i placed all my backups there. But just recently it seems like i have run out of space on the phone, so i can't update some of my apps. I started deleting a lot of photos and videos from my phone and cleared 2.5GB, but i still can't update some of my apps. I began looking through my folders, and noticed that i also have an External SD card partition on my phone. The same one i see when the phone is connected to the pc. In it i can see a Clockwork Recovery folder containing my ROM backups. So i began wondering if the external_sd folder is actually located on the phone and not in the External SD card. Can anyone confirm this?
Also, when i open the Storage (i think that's what it's called) section in the settings on CM10, and noticed that i have 2 Internal Storage sections, one of them has only App data, and the other has photos, apps, music etc. and a SD Card section, with 6.64GB storage left. Does anyone know why is there is 2 Internal Storage sections?
Thank you in advance!

As far as I know the "external_sd" is your removable external SD card. For some inexplicable reason it mounts as a sub-directory from the internal SD card, but it is definitely your removable external SD card.
I have a feeling that Jellybean brings a change and the external SD card mounts in a different way to ICS. I had only a brief experience of this when I played with the leaked ROM but I have reverted to ICS because of battery drain problems.
Your internal memory is partitioned with about 500MB for the system ROM, and 2GB reserved for app installations. Once this fills to around 85-90% you'll begin hitting problems with insufficient storage space errors. If you move apps to SD then this will make use of the data partition of your internal memory (about 12GB available to user on a 16GB device).
I'm running JB (Rootbox 3.2). I set the target path as /extSdCard/Titanium Backup in Preferences for it to work.

So i should move my apps from the App reserved partition to the main storage partition? Or the external SD card? And how do i do that? Sorry for noob questions, i am not too much into how Android works
I don't think you can move apps to external SD card.
Go to settings -> applications and you'll see your apps listed with information about their size. Select one, and you should see a button "Move to SD card". If this is greyed out then the app doesn't support operation from the SD card, but for many you can press the button and it will move the app for you.
The interface in settings isn't the best - I use ZDBox which is a free utility tool available from the Play Store with several useful functions, including an improved "App to SD" UI which makes it easier to see what is going on.
Be careful with widget apps and others that interact with OS functionality as these often don't play happy if moved to SD card.
in your internal memory there is a folder call externel_sd ok leave it coz you still in your internal memory and go search your external sd card memory it named extSdCard or emmc

[Q] Internal Storage-Internal SD card

Hello
I have a galaxy s2 and i wonder what is the difference between internal storage and internal SD card.
In the internal storage i see only apps are installed
and in the internal SD card i have only music photos and others.
it already happened to me that i tried to download an app from the google play and i did not have enough space
is there a way to move my apps from Internal storage to Internal SD card?
(i do not have an external sd card) and if you dont understand what i mean i can upload a screenshot.
thank you
Hello,
Yes, internal storage (or system storage in my phone) is where all the apps are installed.
And internal SD card (known better as internal storage) is where photos, videos etc etc are stored.
This is the only thing i know..
About the moving of apps, i recommend you go to settings -> applications and to the app you want to move and check if you actually can move it. (yes, there's an option to move that app to Sd card) My gues it wont since you need an external storage (or known as SD CARD) if you want to move apps.
If you can't install apps from google play, there are mostly two explanations:
1. Actually insufficient storage. To prevent this, free up memory from system storage by deleting apps/games etc.
2. .odex file causes the erroe. To prevent this, (you need to be rooted) goto /data/app in file manager and find <The app you want to install from google play>.odex
Eg. for second alternative.
If you want to install Swiftkey but get an error. Goto /data/app and delete swiftkey.odex
Internal storage, different names

There the same thing. You can verify by checking the size of the two & the contents to see if they show the same thing.
It would be helpful to know what version of Android your running since this affects how things are displayed.
To find that information open press the menu or home button (bottom left),
Settings
at the very bottom is "About Device"
Look for Android Version
Within most versions of Android (I have 4.1.2 in front of me) what is called "sdcard" or "internal storage" or "internal sdcard" is actually a partition of the device's total internal storage. Unless you are flashing ROMs or running root, you won't see these other paritions.
The internal storage or sdcard is also called sdcard0 or /storage/sdcard0 depending on your version of Android.
The physical sdcard (external storage) is sometimes called /emmc or /extSdCard In later versions you can also get to it as /storage/sdcard1
Hope that helps
Ed
i am running android 4.0.4
and i understand that i cant move apps to there..
i will just buy an external SD card
you helped me alot
Thanks everybody!!

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.

Internal memory

So, under settings -> storage, I'm seeing the external SD card as it should but the internal memory is only 2.35GB. Isn't it supposed to be near to 13GB? I am not getting any low storage space or anything, just setting my available space.
Maybe the space is there with another name, how do I check the available internal space? DiskInfo is showing the similar thing.

There are three storage areas in the stock Rezound...
Apps - about 2.3GB
Phone Storage - about 13GB
These are part of the internal 16GB of storage in the phone itself, and is shared with the operating system, cache partitions, app partitions, and regular storage. They are segmented and cannot be joined and actually seen as one drive.
External Storage - about 15GB (sd card dependant)
each one is it's own partition, you cannot access the "App" area without root access. the Phone Storage is the "HTC STORAGE" drive that opens when you connect to the PC, the unnamed volume is the external SD card.

I can only see
Total space - 2.3, then sub-sections like downloads, cached etc
SD card - (external card space), same sub-sections
Unmount SD

Does your settings like any different?

There is an issue sometimes with the newer ROMs where the internal or external memory is not seen in the ROM but is when connected by USB... You usually just need to format the partition in FAT32 either via CWM/TWRP/Amon Ra or Windows.
Can you browse to it with ES File Explorer or other file manager?

Would you be willing to list out the process for properly formatting the internal storage? I've tried several things, the most recent of which was mounting through recovery and formatting with Windows. However, the internal storage still can't be accessed by the camera, in ES File Explorer, etc. Thanks for any help you can provide.

In TWRP, you would go to wipe - advanced wipe - then select only internal SD option.

I am using the solid exp and here's this folder "Internal memory" at SystemRoot, Now, this internal memory is actually my memory card. At the systemroot, there's another folder named "Storage". This folder has these 3 sub-folders - Internal memory (same as the previous one), sdcard1 (empty with free space 376MB) and usbdisk0 (empty with 376MB).
BTW, using the Xenon HD ROM and as far as I can remember, TRON had the same folders and all.

[Q] [YP-G70][CM11]Storage issues

Hello,
I know this may have been covered already, but I'm somewhat confused.
I have cm11 installed on my SGP5 and it runs fine. However, I'm up to my storage
limit on the internal storage (~1.5GB) even though most of my apps are on USB
storage, and USB storage still has a couple of GB available. What are my options?
I've tried to digest references to Link2SD but I wonder whether I have to format
and partition the external SD first. I have quite a bit of data on the external SD card,
so I don't want to format, if possible. I have also seen references to flipping internal
and external storage or joining both. They confuse me even more!
Is there any way to access that free 2GB of USB storage? Can I resize any of the internal partitions?
I do have experience with partitioning tools on Windows.
Thank you,

Has anyone used the app System Cleaner Root? I tried it, and it freed hundreds of MB
on my internal storage. Could someone explain exactly how it works. I did a search
on Google Play for "dalvik cache" and this app led the list!
Thanks
