If you want to try the new feature now, you will need to install the latest version of the WhatsApp application on your Android phone or iPhone. You can do this by opening the Play Store or the App Store, going to the updates section, then pressing the “Update” button next to the “WhatsApp” application to download the new update. In the event that it does not appear that there is a new update available on the Play Store on your Android phone, you can download the latest version ( 2.23.10.76 ) as an APK file and install it manually to replace the current version of WhatsApp without losing any data. Here we recommend downloading this file from APKMirror .
After the update, open the WhatsApp application on your phone and then click on the additional options button represented by the ( ⁝ ) icon in the upper left corner and from the drop-down menu click on “Settings”, or if you are using WhatsApp on the iPhone, you can go to “Settings”. Settings from the bottom bar after opening the app. After that, go to the “Account” section, and from there go to the “Privacy” options. In this section, scroll to the bottom and click on “Calls”, then on the next page, activate the “Silence Unknown Callers” option as shown in the image below.
From now on, the phone will automatically mute when you receive a random phone call on the WhatsApp application, and if you are wondering how the application will be able to determine what random calls are? It is very simple, if the caller's number is found listed in the "Contacts" contacts, or even if there is a previous regular conversation with this number on the application (without saving it in the contacts list), then you will be notified of who is calling normally, and if it is never found, Incoming calls are immediately silenced but will be displayed in the Calls list and Notification Center as a means of letting the user know that someone is trying to call but their number has not yet been saved.
Unfortunately, the Silencing Unknown Callers feature lacks customization, for example, if you want to ensure that you receive calls from someone, you have to make sure that that person's phone number is saved in your contacts, otherwise you may miss a phone call that you don't want to miss. Also, the phone call will not be made even after repeated attempts, unlike the “Do Not Disturb” feature, the phone will not make any ring or notification even if someone calls you several times in a row.
