Manage contacts on WhatsApp within the app
WhatsApp has an option to add contacts. However, this tab was directing you to your contacts app. For this reason, WhatsApp recently released a new feature that allows users to add contacts or edit their information without having to exit the application. Thanks to this feature, which is currently available to beta users, some beta users can now easily add new contacts to their contact lists or Google accounts without leaving WhatsApp.
With this new update, you can also edit the profile of the user you want to edit. In addition to these, it is possible to add unknown numbers trying to reach you from WhatsApp to your contacts list without going to the contacts application. This update, which is currently available to beta users, is expected to be available to all users soon.
