The recent update of WhatsApp on Windows Phone 8 has fulfilled some of the existed complaints. The new update will allow the user to have a call through the phone’s dialer, though it has not yet integrated a VoIP function like Viber.

Though many complaints about push notifications on the Windows Phone Store exists, the latest version adds support for Windows Phone background agents, which prevents the app from killing off music and other tasks. The new update does make the WhatsApp deserves a smiley for all the changes required.
