The "WhatsApp" application revealed a new communication tool to facilitate making calls in the application, which will allow users to make direct calls without saving numbers in their address book on the phone.

WhatsApp for Android has developed a new communication tool within the application that makes it easier to call numbers that are not saved on the phone.

The new tool is expected to appear as a floating action button within the application in the calls tab on WhatsApp for Android.

This feature is expected to make WhatsApp calls convenient by allowing users to make calls directly from the application, without having to save the contact on the smartphone.

This feature is also useful for making quick calls to new numbers or temporary contacts, which you do not want to store in your phonebook.
