WhatsApp, the very popular Android messenger has a new user interface, based on Material Design.
Material Design was introduced by Google, with the launch of Android 5 Lollipop. Besides the new user interface, WhatsApp’s Android users can now make phone calls over the app without having to be called first.
Another new development from WhatsApp is the integration-tests with Facebook. There is a “share” button that is available right now only to Facebook beta testers.
This WhatsApp update isn’t in the Google Play Store yet as reported by the Italian site androidworld.it, but you can download the apk file of WhatsApp version 2.12.34. (19MB) here.
