If you receive the message "Please connect a device."... while trying to use Samsung Kies from your PC, then this may help you solve your connection problem.First you need to know that their are two types of USB cables, and interfaces... some support both sync and charging and some just support charging. To connect to Kies you need to ensure you are using a sync cable. If you are certain you are using a sync cable... then make sure you are not using something like a battery case that only supports charging. I have a Samsung Galaxy S® II Skyrocket™ (Black) and was using the PowerSkin battery case and wasn't able to connect until I removed the PowerSkin Battery case.
Another issue that may give you a connection problem is that there are different generations of Kies versions, and some phones are only supported on older versions of Kies.
To download the latest version of Kies for your PC go here:
http://www.samsung.com/kies
An alternative would be to use Kies on your phone to transfer files over wifi.
To update the version of Kies on your android phone go to the Google Play Store:
https://play.google.com/store/apps/details?id=com.samsung.swift.app.kiesair&hl=en
Privacy note:
Please keep in mind that when connecting from your PC to the android version of Kies... it will do so via a secure browser window, but it will display the contents of your phone on the screen including photos, media, and other personal information that you may not want to expose to just anyone who can view your screen.
If you need to check for firmware updates, or install firmware updates... you will need to use Samsung Kies for your PC.
