My Samsung Galaxy SII used to mount normally as a USB drive in Ubuntu until the 4.0.3 upgrade. Now the only two options are:

  • connect as Media Device (MTP)
  • connect as Camera (PTP)

neither of the above works properly with Ubuntu 12.04 so I could browse and manage files on the phone and the SD card.

Does Android 4.1 not support the device to be mounted as USB drive anymore?? I tried turning on USB Debugging in developer options but no difference...

Actually, this is even easier: http://www.computerandyou.net/2012/01/how-to-fix-android-samsung-galaxy-s2-not-recognized-on-linux/

Android 4.0.3 does still have the USB Mass Storage feature, it's just hidden in "Other Network Settings" where one would not really expect it...


UMS (USB Mass Storage) was replaced by MTP somewhere with, at latest, ICS. Some kernels still may contain for UMS, but most won't anymore. So here are your options:

  • Check the market for Apps which can enable UMS again (I heard mentioned a few who should be able doing so, including AL Mass Storage Manager, USB Mass Storage Watcher, and Usb Host Controller -- but no guarantees whatsoever, as I didn't try any due to lack of ICS devices
  • install the mtp packages on Ubuntu (apt-get install mtp-tools)
