Android now uses MTP instead of mass storage which means you can't just plug your Android device to your Linux box and access the content. Since the MTP support in Linux is bad, it could be frustrating to find that you just can't connect your Android device to your PC. Your best bet is to try to install gMTP and then try to connect. Good luck with that.
It never worked for me so I gave up on it and adopted a different route which has only one requirement and if you can fulfill it, you will love it. The requirement is WiFi. You need WiFi so that your Android device and talk to your PC.
The solution lies in your Android device. There are couple of apps which allows you to connect your Android device with your PC. Samsung has its own app called Kies Air (it doesn't work on some devices though). I have tried couple of apps and like Air Droid the most. It is available for free of cost and has a very engaging UI.
AirDroid allows you to do more than you expected. You can see details about your devices such as how much free space you have, how many apps you have installed, how many contacts you have.
The icons on this screen is self explanatory so there is not much to write. What is the most important feature is that you can see your tablet in a file browser and manage content. You can import content from your PC to your tablet with greater ease. Similarly you can download content from your tablet to your PC using 'export' button. You can rename files, delete files and move files around. This app is in fact far more faster and responsive than Samsung's own Kies apps.
You can also manage your contact from this app. You don't have to install anything on your PC. All you need is a web browser which can be Firefox or Google Chrome. You can download the app from here.
You can use the tablet while it is still connected to the PC. Also you don't have to worry about connecting the tablet to the PC with the cable. Your tablet can be in a different room and you can still manage it.
