Hi there, I've recently found out samsung galaxy nexus usb protocol doesn't include any UMS option natively or using any roms/apps combination.
I was wondering tho, to make use of some of the space in the internal storage as a common flash drive, is it possible to create a FAT partition and mount it as an external sdcard? More or less like in phones where sd slot is present. Even tho the os wouldnt be able to recognize the new partition itself, I'd be glad to use some of the space as mass storage to connect the device to car radios and stuff like ps3.
Thanks for the attention
Federico
ps: sorry for the poor english it's a foreign language to me

No it's not possible and won't ever be. If it was possible then you would have already found out how to do it.

First off: UMS/MSC is USB Mass Storage/Mass Storage Class
This is something I've been working on. We don't have UMS. And, I want UMS. Google/Samsung's reasoning was they didn't want to make us choose between internal storage for apps, and external storage for music.
The one flaw that comes with this is that we lose UMS. UMS requires a block device that can be unmounted from the phone and mounted to the host machine (Windows/Linux/Mac).
We can get this back relatively easy I believe without re partitioning our phones. I don't want to play with partition tables, because there isn't an easy way that I know of to restore it to stock.
To get technical: /sdcard on the Nexus is just a symlink to /data/media. We can break that symlink, modify the fstab and init.rc to mount an image file to /sdcard, then modify vold to allow us to mount that image file to windows. The downside: we'd lose what google/samsung thought was an amazing idea: not making us choose between sdcard storage and internal app storage.
I guess why I'm posting this: is anyone interested enough for me to actually do this?
What exactly is the benefit? Could you explain?

Sounds like a ext but to the sdcard instead of the data partition..

sounds interesting! the convenience of having UMS is definitely missed. as long as everything functioned "normally" I'd do it.
Yes please! Especially if u can do it so that it'll also work in clockwork, might be easier. It would make everyone's life easier, and I bet a lot of devs would end up baking it in to their roms!

If I am reading this correctly this would essentially make that folder act like it would under an external SD card meaning once I mounted it to windows I would lose all access until unmounting it from windows?
More options are always good, but honestly I've gotten used to MTP and not having to mount and remount as well as not having to worry about swapping between internal storage and sdcard. I say do it just so we have options as users, but I'm not really sure I'd use it over the current methods.

You got it. You could even use the folder as /sdcard and programs wouldn't know the difference.

This would be very very nice for Linux users as mtp can be a pain to transfer files with. And adb isn't exactly the fastest for large files.

Great idea. Mtp sucks

Would love this to use with my MacBook Pro.
I'd use it.

Yes pleaseeeeee!!!!!!!
You should work for Google. I think that's how they should've shipped the phone.
Great idea. That would make device recognition much easier in Linux. It's a real pain trying to get it to pick up GN on Debian. If you get it working maybe I can have your permission to use it in my git for my rom compilation?
Be nice, current method with Macs is painful.

if you read the info for the program you are trying to use you would see it states it doesn't work with Samsung phones (specifically calls out the S3, which has alot in common with the Note II)
I'm surprised the Note doesn't have a native solution for moving apps to external storage? i could have sworn it's been a feature since ICS.... or maybe I'm forgetting something.

So is there any way currently to transfer apps to sd cards on a Samsung device?
Sent from my GT-N7100 using xda premium
At the moment the only solution seems to be rooting. It's stopping me from buying the SGNII until larger internal memory released OR a non-root solution is found. Apparently, it's Jellybean that stops it not actually the phone - just what I've read.
Hi, maybe i'm not the first to ask this question, but i have several problems to manage my note 2 with my Mac. I use Airdroid for small files transfer, but if i want to transfer a rom, or any big file, it's just too slow. I tried to use Android File Transfer but it seems to not recognize anything. Is there anybody that can help me?
Thanks and sorry for some mistakes, i'm italian.
Is usb debugging on or off in developer options?
Android file transfer has been working well on my mac.

You shouldn't buy a Mac..
Macs and android dont go together well.

If I helped you, please hit Thanks..
I also have a mac but haven't had the need to transfer large files over.
Have you tried taking out your micro sd card and transfer files to that?
Sorry I wasn't sure if you were trying to transfer to device memory or just to the phone in general.

I have come from an xperia play, I used to be able to move apps to SD on it when it was running gingerbread or ICS. I have searched and searched but I cant even find it mentioned anywhere that this is not possible on the note 2. Any ideas?
It was also possible to mount the SD card to my computer, through usb sort of like a memory stick. I seem to only be able to to do a slow media transfer now.
This is my first post so forgive me if I have done anything wrong or something considered noobish.

Moving apps to sd is possible when the app lets you do it, just see the details for each app on the app manager.
As for the usb/media mode, guess you can't really choose anymore, but check your cable, mine seems pretty fast to transfer files

I have the 16GB model and I must say it fills up pretty fast. I am using DirectoryBind and it is working great for me. It requires root access and one or two reboots but it's well worth it.
Another solution to the low internal memory is a mod called Ext2InternalSd which basically switches between your internal and external memory. I find it quiete extreme as a solution but that's just my opinion.
We are stuck with MTP mode now instead of USB mass storage.
Its not bad, but at least with UMS I could see the previews of my images when connected to my computer. With MTP I can't

Welcome to jelly bean
scribbled from my note 2 (N7100)
ICS does not allow to install to SD Card/// You can run a script on a rooted rom that swaps the internal memory for the external... Look it up dude
Use airdroid. One of my favorite apps.. solution to mtp

I'm having trouble with MTP using the latest version of Paranoid Android, it's SO slow, I just copied a 5MB file to the phone and the transfer lasted like 15 seconds, also, I really don't like that "media" layer thats added, I need to make some space in my internal storage/SDCARD and I can't even use a program to calculate the folder sizes, I want direct access to it, just that, I don't understand why it's not available in AOSP.
Well, I searched and someone said "hey, mount the storage/sd with recovery", ok, here we go. And nope, last TWRP doesn't work for some reason. OK, lets go back to CMW. And nope, again, can't mount them, it just won't work, nothing happens when I check the mount button...
Also I read that using the "Fix permissions" fix may solve it, well, it doesn't, tried that with both recoveries.
So, is there any way to enable USB Mass Storage Mode? Also, why is MTP SO DAMN SLOW? I've searched and I'm not the only one thats having this problem it seems.
Thanks.
Anyone?
Samsung made it like that, you cant do nothing about thet so far.

Can you explain a bit further about that? What did Samsung do?
Cant sorry, samsung made your sd car like a media storage not all file storage, more for music, movies, pictures, thats one of the reasons why samsung wont let you save apps on sd card.
