When I mount my Android phone with USB cable to Ubuntu 12.04 I get "these files are on a digital audio player" and open with rhythmbox in nautilus.This means that I am not able to see any file within my android.
Is it possible to disable the recognition of digital audio player and just list all files as usual?
I found the issue. The issue was completely different than I thought. I actually have a Samsung galaxy S2. If you plug in the phone via USB you can see the device but you are not able to see any files.
But if you follow this guide, you will be able to see all files;
Thanks everybody for your efforts.
