What are my options for connecting my Android to Ubuntu?
With the problems I had with different devices and versions of Android, I found that the most effective and the easiest way to access files on my device is to use AirDroid. Although this will not mount the Android device as a file system, but will allow an easy file transfer. All you need is a wireless connection of your phone to your local network. Once AirDroid is started, you get a web interface that you can access from your desktop computer's browser, using the port 8888. AirDroid is a free application on the Play Store and received great scores so far from everyone.
