Call Blocker (Android)

This Article Applies to:

  • Small Office Protection

With Call Blocker, you can block all calls from phone numbers on your Blacklist. When a call is blocked, the caller is automatically redirected to voice mail.

Due to recent changes in the Google Play Developer Policy Center and Android policies, the Call Blocker feature will no longer be available in Avast Mobile Security on devices running Android 8 and higher.

  1. Tap the Avast Mobile Security icon on your device to open the app
  2. Tap Menu ▸ Call Blocker
  3. Tap the plus icon, then select which number(s) you want to blacklist:
    • All unknown numbers
    • All hidden numbers
    • A number you can enter manually into the app
    • A particular contact from your contacts list
  4. Past blocked calls are visible under the History tab on the main screen of Call Blocker.
