Are you tired of receiving unwanted calls from unknown numbers? In this tutorial, we will show you how to block unknown calls on your Android device. By following these simple steps, you can regain control over your phone and enjoy a peaceful calling experience.

Step 1: Open the Phone App

To begin, open the Phone app on your Android device. This app is usually located on your home screen or in the app drawer. It is represented by a green phone icon.

Step 2: Access Call Settings

Once you have opened the Phone app, look for the three-dot menu icon in the top-right corner and tap on it. A dropdown menu will appear.

From this menu, select “Settings. “


If your device has a slightly different interface or uses a custom skin from the manufacturer, the location of these settings may vary slightly. However, most Android devices have a similar layout for call settings.

Step 3: Locate Block Numbers

In the Settings menu, scroll down until you find an option called “Block numbers” or something similar. Tap on it to access the blocking options.

Step 4: Enable Block Unknown Calls

In the Block numbers settings, you should see an option labeled “Block Unknown Calls.” This feature allows you to block calls from unidentified numbers that are not saved in your contacts list.

  • To enable this feature:
    • Toggle the switch next to “Block Unknown Calls” to turn it ON.
    • If prompted, confirm your selection by tapping “OK” or any similar confirmation button.
    • You have successfully enabled the block feature for unknown calls on your Android device.

Step 5: Verify the Block

Once you have enabled the block feature, test it by asking someone with an unknown number to call you. If the call is blocked, your phone will either reject the call or redirect it to voicemail, depending on your device’s settings.


Blocking unknown calls does not guarantee that all unwanted calls will be blocked. Some scammers and telemarketers may use tactics to bypass these restrictions. In such cases, it is recommended to report these numbers to your service provider or install a third-party call-blocking app for added protection.

With these simple steps, you can now block unknown calls on your Android device. Say goodbye to annoying interruptions and enjoy a more peaceful calling experience!
