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...
