WhatsApp voice calling feature for Android now online
With no OTA update yet, the new version is available on the company website.
It's finally here! WhatsApp's new calling feature has finally been released, at least for Android phones. While the new functionality is open to all users, without any invites (or workarounds) required, you need the latest version to access it. The update hasn't yet been pushed over-the-air but you can download the new version 2.12.19 apk from here or directly from WhatsApp's website. Remember to enable third party apps in your phones Security Settings before you try to install this. Once that's done, the app will reflect the new interface, with a separate tab for Calls at the top, alongside Chats and Contacts.
Edit: It's official, WhatsApp has begun rolling out the updates over-the air. Expect your notification to pop up anytime soon.
