Since WhatsApp is a service that is indispensable for modern days communication world wide, there is no doubt there is a need for a WhatsApp Icon redesign.
The old iconography with the speech bubble and the classic phone served well as a startup.
But that was then, a modern look now is required to match the Apps importance and possibilities.
Other services did reasonable good to evolve their brand appearance to their enormous growth, WhatApp does not want to stay behind.
Thanks for watching, a like or any comments are very much appreciated.
