Good news, WhatsApp gets call waiting feature:
WhatsApp is the most recent Voice Over Internet Protocol (VOIP) service provider to support call waiting features even if the company has ignored call holding for the time being.
As you chat on the phone and someone else tries to call you, mobile devices and operators should inform you that you have a call waiting. Some VOIP services do support this feature, and WhatsApp is now among them.
The latest WhatsApp beta update has also introduced 3 new options for dark mode on the app that you need to check out.
