Google’s Phone app, available on many Android devices, offers a spam filter that can help identify and block spam calls. To enable this feature:

  • Open the Google Phone app on your device.
  • Tap on the three-dot menu icon and select “Settings.”
  • Choose “Caller ID & Spam” or “Spam and Call Screen.”
  • Enable the options “Caller ID & Spam” and “Filter spam calls” by toggling the switches on.
  • This feature will now warn you of suspected spam calls and automatically block calls classified as spam.

3. Employ Third-party Call Blocking Apps:

There are several call-blocking apps available on the Google Play Store that offer advanced features and customization options to help you block spam calls more effectively. Some popular call-blocking apps include:

  1. Truecaller: Truecaller is a widely-used app that identifies and blocks spam calls by relying on its extensive database of known spammers. The app also allows users to report new spam numbers, contributing to the community-driven spam-blocking effort.
  2. Hiya: Hiya is another popular call-blocking app that offers spam detection and call-blocking features. In addition to blocking known spam numbers, Hiya also provides caller ID information for unknown callers.
  3. Call Control: Call Control is a comprehensive call-blocking app that uses a community-driven database to identify and block spam calls. The app also features a personal call-blocking list and can block calls based on area codes or prefixes.

To use a third-party call-blocking app, download and install your preferred app from the Google Play Store. Follow the app’s onboarding instructions to set up call-blocking features according to your preferences.

4. Register for the National Do Not Call Registry:

In some countries, including the United States, registering your phone number with the National Do Not Call Registry can help reduce the number of telemarketing calls you receive. Although this method may not block all spam calls, it can considerably reduce calls from legitimate telemarketers. To register your number, visit the appropriate website for your country, such as for the United States, and follow the instructions provided.

5. Report Spam Calls to Your Carrier:

Many mobile carriers offer tools and services to help their customers block spam calls. Contact your carrier’s customer service to inquire about any available spam-blocking options. Some carriers may offer a free or subscription-based service that can help filter out unwanted calls. Additionally, reporting spam calls to your carrier helps them gather information about spammers and develop better solutions to combat the issue.

6. Be Cautious About Sharing Your Phone Number:

One of the most effective ways to minimize spam calls is to be cautious about sharing your phone number. When signing up for online services, newsletters, or entering contests, consider using a secondary phone number or an app-based number (like Google Voice) instead of your primary number. This can help keep your main number off telemarketer lists and reduce the number of spam calls you receive.

7. Adopt a “Silent Treatment” Approach:

If you’re still receiving spam calls despite using the above methods, you can try adopting a “silent treatment” approach. Set your phone to “Do Not Disturb” mode and allow calls only from contacts or specific numbers. This way, any calls from unknown numbers or spammers will be silenced, and you can check your call log later to see if you missed any important calls.

To enable “Do Not Disturb” mode on Android:

  1. Open the “Settings” app on your device.
  2. Scroll down and select “Sound” or “Sound & vibration.”
  3. Tap on “Do Not Disturb” or “DND.”
  4. Toggle the switch on and customize the settings to allow calls from contacts or specific numbers only.


Spam calls can be a major disruption to our daily lives, but with the right techniques and tools, you can effectively minimize their impact. By utilizing built-in Android features, third-party apps, and careful sharing of your phone number, you can regain control over your call experience and enjoy a more peaceful, spam-free phone environment. Be proactive and take the necessary steps to block spam calls on your Android device, keeping your focus on the things that truly matter to you.
