Nautilus does not detect the phone internal memory.

Can you access the sd card? I'm not sure but, you may need the Android SDK which includes ADB to access the internal memory.

Good Luck. ;-)

AFAIR MTP is the new thing since ICS (?), and before that Linux was always detecting the device as a USB Mass Storage. However, since ICS the "default mode" is now always MTP, which Linux cannot understand without the drivers.

Whereas MTP worked flawlessly for me on Windows 7 (I use it for games only :P), on Linux you can use the old method of connecting as a mass storage, it's a little more tedious but still:

1. Before connecting your phone, go to (phone's) Settings -> More... -> USB Utilities -> Connect storage to PC
2. When a dialog "Connect USB cable to use mass storage" has appeared, connect your cable
3. The USB-Android will appear saying "USB connected", click "Turn on USB storage"
4. Next dialog warns you about some applications that may stop as a result, click "OK".

Note: I'm using Squeeze with SGS2

after doing Factory Reset,
it is ok now. Easy to connect to Windows 7.

Thanks for the update.

Hi there
At the top of the phone, you'll hopefully see a bar with the USB symbol. Pull this bar down and disable USB debugging. Or alternatively, Settings | Applications | Development | then untick USB debugging.

When connected via the USB cable, Ubuntu will automatically mount the SDcard (or at least it does for me running Ubuntu 12.04 Desktop).

Good luck.

If your phone's like mine, the computer does not see it or recognize it until the device is put into sharing mode. Apparently it can emulate several different very-different device types, so it doesn't announce its presence on the bus at all until you put it into one of those modes. Doesn't matter what operating system you're using on the host.

Install Airdroid from google play. It allows you to transfer files between phone and PC and vice versa via a web browser. You can access both internal and external storage. No need to worry about MTP, USB mass storage or operating systems issues.

I get this error msg when trying to connect Android 4.1.1 Samsung SGH-T999 (Galaxy S3):

Unable to mount SAMSUNG_Android_SGH_T999

Error initializing camera: -60: Could not lock the device

The 2 Nautilus windows come up, I can see the folders inside, but no files INSIDE those folders.

I also tried CTRL-H or view hidden files; and still, no files.

This is when the settings on the phone are in MTP.
When I change it to Camera (PTP), I can see the folders, I can see the pictures inside the DCIM folder, but no more files, no music, no text files, no anything.

I also get the same error msg as before.
I never had a problem with previuos Android phones, on Ubuntu, and the problem IS NOT only in Ubuntu...also tried Linux Mint 12, and Mandriva...same problem. No problem connecting to Windows & Mac, just Linux and this Galaxy SIII.

I also do not understand that the system asks me to Open Rythmbox Music Player. When I do this, the music player opens, but no music is found.

So, what am I doing wrong?

Thank You!!
