How to Automatically Block Spam Calls on Android

Spam calls are more than just an annoyance they can waste your time, disturb your day, and even pose a security risk. If you’re constantly bombarded with unknown numbers and robocalls, you’re probably wondering how to automatically block spam calls on your Android phone. Luckily, Android offers several tools, apps, and settings that can help you avoid spam calls altogether.

How to Automatically Block Spam Calls on Android

In this guide, we’ll explore the best methods to block spam calls on Android automatically, so you can enjoy a hassle-free phone experience.

Method 1: Using Google’s Built-in Spam Protection

Many Android devices come with built-in spam protection, especially if you’re using the Google Phone app. This app has a robust spam detection feature that flags potential spam calls before you answer them. When you get a call from a suspicious number, it will show up as “Spam” or “Suspected Spam” on your screen.

Steps:

Open the Phone App: Launch the Google Phone app on your Android device.
Go to Settings: Tap the three dots in the top-right corner to open the menu, then select Settings.
Tap on Caller ID & Spam: In the settings menu, find and tap Caller ID & Spam.
Enable Spam Call Blocking: Toggle on the options to both See Caller ID & Spam and Filter Spam Calls. This will automatically block numbers that Google identifies as spam.

Once this is enabled, your phone will automatically block spam calls, sending them straight to voicemail without even ringing your phone. This is one of the easiest ways to keep those pesky robocalls away without the need for any additional apps.

Method 2: Using Third-Party Apps to Block Spam Calls

If your Android device doesn’t come with Google’s built-in spam detection, or if you want more control over blocking spam calls, you can use third-party apps. These apps provide advanced call blocking features that can identify and block spam calls automatically.

1. Truecaller

Truecaller is one of the most popular call-blocking apps available on Android. It has a massive database of spam numbers and uses community-based reporting to keep the list up-to-date. It automatically identifies spam calls and can block them without your intervention.

Steps:

Download Truecaller from the Google Play Store.
Open the app and go through the setup process, granting permissions to access your contacts and call logs.
Enable Spam Call Blocking: Once the app is set up, go to Settings and enable the Block Spam Calls option.
Customize Settings: You can choose to block all unknown numbers, only high-risk spam, or any number not in your contacts.

Truecaller also allows you to report spam numbers, helping other users avoid the same spam calls you received.

2. Hiya

Hiya is another great app for blocking spam calls on Android. It works similarly to Truecaller by identifying incoming spam calls and blocking them automatically. Hiya uses a large database of known spam numbers and updates frequently to keep you protected.

Steps:

Download Hiya from the Google Play Store.
Open the app and follow the instructions to set up spam protection.
Enable Auto Block: Go into the Settings and toggle on Auto Block Spam Calls.
Customize Blocking Preferences: You can set Hiya to block only confirmed spam numbers or be more aggressive by blocking all unknown numbers.

Both Truecaller and Hiya offer free versions with basic spam blocking features, but they also provide premium versions with extra tools and more detailed call analytics.

Method 3: Blocking Calls Using Your Phone’s Built-In Settings

Many Android devices come with basic call blocking features built into the phone app itself. While these might not be as advanced as Google’s spam protection or third-party apps, they still provide a simple way to block specific numbers or unknown callers.

This method is great if you only need basic call blocking and want to block specific numbers or unknown callers without downloading extra apps.

Method 4: Using Carrier Services for Spam Blocking
