Ok, I don't usually go out with my micro USB cable so when I in need of transferring data from Laptop to my Samsung Galaxy Mini (Android Phone) or vice versa, there is only one way I know how to do it wirelessly and efficiently (I mean no cost at all or burdening your data plan), by Bluetooth connection.
These all were always be my partner in most of my outdoor activities (and most of it were for work). My laptop don't have the bluetooth device onboard so I have to get a bluetooth dongle (the nail size USB device over the S of TOSHIBA).
My Laptop's main OS is Ubuntu 11.04 (obviously this blog is all about Ubuntu, and some Samsung Galaxy Mini) and the bluetooth dongle is something I won over my friend.
Well, lets begin. If you already have bluetooth connection from Ubuntu to your Android Phone, than skip step 1 and continue to step 2 or step 3, depends on your need.
1. CREATING BLUETOOTH CONNECTION
BETWEEN LAPTOP (UBUNTU) AND SAMSUNG GALAXY MINI (ANDROID PHONE)
1. Plug the Bluetooth USB Dongle in and let Ubuntu recognize it (an Indicator Applet will show the sharp Bluetooth icon)
2. Prepare your Samsung Galaxy Mini bluetooth connection by touching the App List, swipe your way so that you'll find Settings, touch it. Touch the Wireless and networks and touch Bluetooth settings. Tap on the blank Bluetooth check mark on to turn bluetooth on and tap on the blank Visible check mark to let your Laptop see your phone (this will stay on for about 120 seconds so do the step 3 real fast OK)
3. Make the Bluetooth connection by clicking on the Bluetooth Icon and select Set up new device. It's a wizard, so please do follow it fast (if you do it fast, you got 100 second window time at most).
4. After the wizard find your phone (it will show you the product serial name, and I'm using Samsung Galaxy Mini so it should show you GT-S5570 with type phone) select the phone and press forward. If you hurry, you still got about 80 second to do this.
5. See that line of numbers up there (you might get different number because it's randomly generated by Ubuntu)? Your phone is surely asking you to enter the same number in it so that there will be safe connection between your phone and Ubuntu. Quick put them in your phone, you got less than 15 second to do this.
There, Mission One Accomplished. Creating bluetooth connection between Ubuntu and Android is Done.
2. COPYING FILES FROM LAPTOP (UBUNTU) TO SAMSUNG GALAXY MINI (ANDROID PHONE)
1. Remember the term drag an drop? well that is what you'll do. Turn your phone's Bluetooth on and on the Laptop, click the Bluetooth Icon, hover on GT-S5570 (Samsung Galaxy Mini product code), a new menu will pop out, select Browse file.... Doing this will opens up a File Manager (here shown Nautilus pointing on your phone).
2. Open Another File Manager to your source file (those that you want to copy)
3. Copy the files you need to be on the phone (e.g. musics or video clips) by dragging it to the file manager that points to your phone. NOTE : You Can Not Copy Or Drag A Folder To Your Phone (It might be some security system implanted on Android Phones because theres no trouble doing that on Nokia Phones and Nokia Phones usually prone to be hack by other people).
There, Mission Two Accomplished. Copying Files From Ubuntu to Android is Done.
3. COPYING FILES FROM SAMSUNG GALAXY MINI (ANDROID PHONE) TO LAPTOP (UBUNTU)
The only direct way I know is by using an app that you have to download from Android Market. but I know a way that do not require any app to download. here is how :
1. Turn your Android Phone's Bluetooth on, open your phone's File Manager My Files, browse to your file that you need to transfer.
2. Push your phone's menu button (not in the screen, but on the phone. For Samsung Galaxy Mini, its the left button below the screen. Touch More (the icon that look like a big circle and an upside down triangle in it), touch Bluetooth visibility and then mark the file/files you need to transfer as the picture below. Touch Done when finished marking the file/files
3. Click the Bluetooth Icon, hover on GT-S5570 (Samsung Galaxy Mini product code), a new menu will pop out, select Browse file.... Doing this will opens up a File Manager (here shown Nautilus pointing on your phone).
4. Just copy the file you need to the directory located on your Laptop
There, Mission Three Accomplished. Copying Files From Ubuntu to Android is Done.
Copying Files from Android Phone to Ubuntu Laptop requires you to make the files you need to copy to be visible under Bluetooth connection seems like a Security Prevention System that Android Phone use to limit the visibility of their device hence more to do for hacker to hack in to Android Phones.
There, this way I don't need to bring micro USB cable all the time. BTW, Bluetooth Dongle is always auto detect in all Ubuntu system, while Windoze only do the same in Windoze 7. NOTE : Transferring Files Via Bluetooth Takes Longer Time Than Using Cables, So This Is Only Good For Files Under 100MB, More Will Be Very SLOOOOOOOOOWWWWWWWW
