Keeping up the pace with recent mobile client releases, Microsoft has released the mobile client for Lync 2013 on Android powered devices. Among some of the nice features are the ability to require WiFi for VoIP and/or video calls, control over call forwarding settings, receive calls after exiting the app, and more. Single touch meeting join is also a nice feature. Fellow Lync MVP Matt Landis has done a full breakdown of the client in his blog post here.
