How to Block Unknown Numbers on Android

Blocking unknown numbers on Android can help you avoid unwanted calls or messages from unfamiliar or anonymous sources. Here’s how to block unknown numbers on most Android devices:

Using the Phone App:

1. Open the “Phone” app on your Android device. This app may be called “Phone,” “Dialer,” or something similar, depending on your device and Android version.
2. Tap the three-dot menu icon in the top-right corner of the app. This will open a dropdown menu.
3. Select “Settings” or “Call settings” from the menu.
4. Look for an option called “Blocked numbers,” “Blocked calls,” or “Spam and Call Screen.” Tap on it.
5. Tap on “Blocked numbers.”
6. You’ll see an option to add a number to be blocked. Depending on your Android version, you may need to add the number manually or choose from recent calls and messages.
7. To block an unknown number, you can either enter the number manually or select a recent call or message from the unknown number to add it to the blocked list.
8. Confirm your choice to block the number. Once blocked, you won’t receive calls or messages from that number.

Note: The exact names and locations of these settings may vary slightly depending on your Android device’s manufacturer and version of Android. If you can’t find the specific settings, try searching for “Blocked numbers” or “Call blocking” in the phone app’s settings.

Additionally, some Android devices may have additional options for blocking unknown or suspected spam calls and messages. These options often use databases of known spam numbers to identify and block unwanted calls automatically.

If you’re receiving a significant number of unwanted calls and text messages, you may also consider using a third-party call and SMS blocking app from the Google Play Store. These apps offer more advanced features and often provide better control over blocking unwanted communications.
