When you receive a call, Kaspersky Who Calls displays a pop-up window with information about the phone number.
By default, the caller ID pop-up window appears twice:
On the incoming/outgoing call screen - so you can view information about the phone number before you answer/call it.
After incoming calls - so you can instantly check who called and mark the number as spam, if necessary.
You can configure the app to display the pop-up window only once: either on the incoming call screen, or after calls, or you can turn off the feature.
To set up the caller ID feature:
In the navigation bar, tap .
Select the type of calls for which you would like to set notifications: Incoming calls or Outgoing calls.
In the Notification with information about the number section, choose the mode for which you would like to set the notifications: During the call or After the call.
Notifications after the call are only available for incoming calls.
In the dialog window that opens, select one of the options:
If you want to receive notifications only about calls to or from numbers that are not in your Contacts list, select Only for numbers that are not in my Contacts list.
If you want to receive notifications about all calls, including calls to or from numbers that are in your Contacts list, select For all numbers.
If you don't want to receive notifications about calls, choose Don't show. The app will continue to identify spam, and spam calls will be marked as spam in the call log.
