I have a best friend. I have had it for quite some time though and now it and I are one. It is my Samsung S3. If you have a similar device from Samsung, like the epic Galaxy Note 2, here is a great tip for connecting to your computer.
1. Download Kies from Samsung. A programme which syncronizes everything on your phone with your computer, EVERYTHING. From photos and contacts to bookmarks from your browser. I also use Kies for text messages where I have put Kies on the Quick Start Menu and it plays a notification sound with a popup when I get a text and enables me to answer it via my computer.
2. Download Kies Air from Google Playstore. Kies Air is a application that enables you to easily manage contents saved on your device via PC internet or mobile browser using Wi-Fi technology. NO CABLES, I love it!
3. Open Kies on your computer.
4. Open Kies Air on your phone and push START.
5. Kies Air on the mobile device will display a URL. Enter the URL in the browser on the PC or laptop
6. Kies Air will display a 4-digit PIN on the mobile device. When prompted, enter the PIN into the browser on the PC or laptop.
7. Enjoy.
This is from my experience the most flawlessly program so far for connecting a smartphone to the computer. It simply works.
