Available to select users previously, WhatsApp has commenced rollout of its voice calling feature to all users on Android.

The feature is automatically enabled to all users updating to version 2.12.5 of WhatsApp
via the Play Store, which brings a revamped user interface sporting
three tabs: Calls, Chats and Contacts. Initiating a voice call is as
easy as tapping the dialer icon that is available in-chat, or heading to
the Calls tab and selecting a contact you wish to call.



The update is in the process of rolling out, so if you don't see it
yet, just give it time. For users that have the voice calling option
enabled, how are you liking the feature?
