Skype this week unveiled an update to its Skype for Android app that adds support for more than a dozen popular Android devices.

In all, Skype 2.5 for Android brings video calling to 14 new Android phones and tablets, bringing the total number of supported devices to 41.

Additionally, video chat has been drastically expanded to a bunch of new devices, including:

• Samsung Galaxy Tab 10.1
• HTC Nexus One
• HTC Shooter
• Sony Ericsson Xperia Live with Walkman
• Sony Ericsson Xperia neo V
• LG Optimus Black
• LG Optimus 3D
• LG Optimus 2x
• Motorola Photon
• Motorola Droid 3
• Motorola Bionic
• Motorola Xoom
• Motorola Atrix
• Acer Iconia

Additionally, Skype has added some improvements to the video calling interface. Users can now switch between portrait and landscape modes, and use double-tap-to-zoom to get a closer look at their subject. There is also better support for Bluetooth headsets and various bug fixes and performance enhancements.

Finally, Skype has added the in-app ad system that showed up in the iPhone app update earlier this week. Like on the iPhone, users that have active Skype credits, a subscription calling plan, or are Skype Premium members will not see ads.

Download the updated Skype for Android app from the Android Market or Skype.com/m using your Android phone’s browser.
