In February 2014, popular mobile messaging service WhatsApp announced that it soon plans to roll out voice calling feature for its users. However, other than a few hidden elements in the service's Android app, there are no signs of the feature yet.
Now, an Android focused website, Androidworld.nl has published alleged screenshots of a build of the WhatsApp app that offers calling features. Perhaps the build is being used by testers or employees and the features will be included in the official build when it's finally announced.
The screenshots suggest that there would be separate screens for dialing a voice call to WhatsApp contacts, call logs and ongoing calls. One of the shots of a conversation window also features received and missed call icons though. It's difficult to verify the authenticity of the screenshots and WhatsApp has not confirmed that it's testing it via beta builds.
