6 Best Spam Call Blocker App for Android

We’ve all received annoying calls from telemarketers or scammers, and we all know how frustrating they can be. Sadly, while certain Android phones have a blocking capability as a built-in feature, most Android phones do not. As a result, we have compiled a list of the most reliable and efficient call blocker apps for Android, which can be found below. Now, let’s look at the list of the best free call blocker apps for Android. Indeed, there are not too many, but we’ve done our best to compile a list of some of the most useful apps you can check out right now.

Truecaller – Caller ID & Block

---

Truecaller is an app for smartphones that will show you who’s calling, even if the person isn’t on your contact list. What the app is able to provide is the information of callers who are not among your contacts, like marketers or spam callers. It also has the ability to block unwanted calls such as the above, allowing you to be less interrupted, or not interrupted at all. The Truecaller app is available on both Android and iOS platforms, and it will require an active Internet connection (Wi-Fi or mobile data) to work.

Features

• Record Phone Calls: Truecaller allows all Android users to record incoming and outgoing calls seamlessly.
• Back Up Your Contacts and Call Lists: Truecaller now has its own backup feature to store everything about your contact book by setting up automatic backups on your phone.
• Integrate with Other Apps: Truecaller integrates with your device’s Phone and Message apps, so you can use both of them in Truecaller without having to close it.
• Look Up Numbers with Your Camera: One of the coolest unheralded features of Truecaller is its camera lookup. When you come across any number, whether on a piece of paper or a giant sign somewhere, simply open the Truecaller app and tap the QR scan symbol at the edge of the Search bar.
• Call Alerts: Truecaller also sends call alerts that notify you of an incoming call even before your phone rings. A Truecaller popup appears on your phone seconds before the call drops, stating the name of the caller. This feature is pretty cool because it ensures that no call takes you by surprise.

Pros

• Extensive spam listings.
• Report numbers as spam.
• Block SMS and calls.
• Crowdsourced spam blocking.

Cons

• Wonky activation process.
• Cannot block prefixes or whole area codes.

Hiya – Call Blocker, Fraud Detection & Caller ID

---

Hiya (previously White Pages Caller ID and Call Blocker) was once just a reverse-number lookup service. Now the app also blocks calls and offers a caller ID service. Hiya is good at identifying numbers because it analyzes more than 3 billion calls each month to give users context around their incoming calls. Like Truecaller, once you register, your calls are among those analyzed.

Features

• Phone spam protection: Hiya identifies and blocks robocalls, telemarketers, debt collectors, and fraud calls like neighbor spoofed call scams.
• Call blocker: Hiya automatically blocks scam and fraud calls and stops the “neighbor spoofing” calls from numbers that look similar to yours.
• Caller ID: turn an unknown caller into a name. Whether it’s a call from a business, friend or potential spammer, our global database of caller names gives you real-time context on who’s calling.
• Reverse search: look up the phone number of a call from an unsaved contact to find out the true caller name and whether it is likely a robocall.
• Manage contacts: add names and addresses from Hiya to your phone book contacts to keep them accurate, complete, and current.

Pros

• Free with no ads
• Large contact database
• Easy-to-use
• Reliable call and SMS blocking

Cons

• Occasional speed issues

T-Mobile Scam Shield

---

T-Mobile’s Scam Shield is a mobile app that helps to prevent scammers from reaching us through our mobile numbers. The app is a tripartite development between the National Crime Prevention Council (NCPC), the Open Government Products team from the Government Technology Agency and Singapore Police Force (SPF). The app focuses on two main functions – blocking scam numbers and filtering scam messages into junk. The scam messages are identified and filtered using artificial intelligence by the application.

Features

• Scam ID and Blocking: suspicious calls are flagged, and you have the option to block those numbers completely.
• Enhanced Caller ID: a sophisticated tool that verifies numbers coming from real people or businesses.
• Second Number: another way for those you love to reach you, on a more private line.
• Number Change: the option to change your number completely if the robocalls become too intense.
• Be ID Aware: a program designed by McAfee to help ward off identity theft. Get 12 months for free when downloading the app.
• Scam Shield App: the nucleus, where the above features can be monitored or tweaked and offers additional features for a fee.

Pros

• The app is available for both iOS and Android and, thanks to some massive mergers, for clients using T-Mobile, Metro by T-Mobile, and, eventually, Sprint. It even works for landlines.
• Scam Shield comes with more protection options than those offered by other major service providers.
• Most of the main features are free, and those who were previously paying for T-Mobile’s Name ID will no longer be charged for the service.
• Easy to use. The Scam Shield app centralizes all functions, making it a one-stop-shop for everything from adding blocked numbers to changing your number.

Cons

• While a majority of the features are free, not all of them are. T-Mobile charges $4/month for premium features such as creating “always block” lists and sending specific telemarketer categories directly to voicemail.
• T-Mobile’s scam-identifying tech is good but imperfect, and the Scam Shield may accidentally block some legitimate phone calls.
