WhatsApp's latest feature currently in development is a new in-app dialer. The feature was discovered in WhatsApp beta for Android v2.24.9.28 and it is not available to testers yet.

Microsoft has now taken the wraps off a Skype 'alpha' app for Android that eventually aims to offer the same features as the Windows 10 version by bringing SMS and call functionality to the platform.
The dialer app comes out of beta for Windows 10, as Truecaller continues to add features even to its Windows Phone 8 version.
Reportedly built by the Skype team, Dialer is said to include geo-search for local contacts and Truecaller-style caller-ID. Launching in December on Android, a Windows 10 Mobile version is coming too.
