Do you often receive unwanted calls from unknown numbers on your Android device? It can be quite annoying and intrusive.

The good news is that you can easily block these unknown callers and regain control over your phone. In this tutorial, we will guide you through the process of blocking unknown callers on Android.

Step 1: Open the Phone App

The first step is to open the Phone app on your Android device. This app is usually located on your home screen or in the app drawer. Tap on the icon to launch it.

Step 2: Access Call Settings

Once you have opened the Phone app, look for the three-dot menu icon at the top-right corner of the screen. Tap on it to open a dropdown menu. From this menu, select “Settings” to access the call settings.

Step 3: Find and Select “Blocked Numbers”

In the call settings menu, scroll down until you find an option called “Blocked numbers.” This option may be located under different sections depending on your device’s manufacturer or Android version. Once you find it, tap on it to proceed.

Step 4: Add a Number to Block

In the Blocked numbers menu, you will see a list of any previously blocked numbers. To add a new number to block, tap on the “+” or “Add” button (the exact wording may vary). This will open a new window where you can enter the number manually or select it from your contact list.

Option 1: Enter Number Manually

If you know the specific number that you want to block, choose this option. Enter the number in the provided field and tap on “Block” or “OK” to confirm.

Option 2: Select from Contacts

If the number you want to block is saved in your contact list, choose this option. Tap on the “Contacts” button to open your contact list. Find and select the desired contact, and then tap on “Block” or “OK” to confirm.

Step 5: Verify Blocked Number

After adding a number to block, it will be displayed in the Blocked numbers menu. Double-check to ensure that the correct number has been added. You can also edit or remove a blocked number from this menu if needed.

Step 6: Block Unknown Callers

In addition to blocking specific numbers, you can also block all unknown callers on your Android device. To do this, toggle the switch next to “Block unknown callers” or similar wording in the Blocked numbers menu. Enabling this option ensures that any call from an unknown number will be automatically blocked.


Blocking unknown callers on your Android device is a simple yet effective way to avoid unwanted calls and maintain your privacy. By following the steps outlined in this tutorial, you can easily block specific numbers or enable blocking for all unknown callers. Take control of your phone and enjoy a hassle-free calling experience!
