Can't connect Samsung Galaxy S3 to my laptop
To access files from your phone on your computer, you need to have it hosted as a media device. Often these are found in your settings (in my case, when I plug the USB cable my phone asks me whether to charge phone only, or host as media device.) These are most likely found in your settings if it does not ask. Once you get that far, you need the drivers for your phone to be installed on the computer. Often they automatically install once your phone connects, but you may need to install them manually. Feel free to comment for anything you don't understand, but please try to make it understandable. They can be found here for your phone: http://www.samsung.com/us/support/downloads
