Make free Skype-to-Skype video calls, and call phones at Skype rates on the move. Skype 2.1 for Android lets you make free voice and video Skype-to-Skype calls, and call phones and landlines at great Skype rates on the move. Video calling now supported on more Android phones.
* Data plan or WiFi connection required You need Android v2.2 to run Skype on a Samsung Galaxy S Please sign out of Skype to close the application. On Android 2.2 (Froyo), only the back camera will work. This is because only devices running Android OS 2.3 or higher allow apps to access the front facing camera. If the setting to enable video calling is not available in the Skype Settings on your device that means video calling is not yet supported on your phone.
