How to Stop Spam Calls on Android: A Complete Guide
Spam calls have become one of the most annoying problems smartphone users face today. Whether it’s telemarketers, robocalls, or fraud attempts, these unwanted calls waste time and can even pose security risks. If you’re an Android user, you’re not alone—millions of people deal with spam calls daily.
The good news is that Android devices provide several tools and settings to block, filter, and manage spam calls effectively. In this detailed guide, we’ll explore all the practical methods you can use to stop spam calls on Android and take back control of your phone.
Why You Keep Getting Spam Calls on Android
Before jumping into solutions, it’s important to understand why you’re receiving spam calls:
- Data Leaks – Your number may have been leaked through data breaches.
- Online Registrations – Signing up for services and apps without reading privacy policies can expose your number.
- Robocall Generators – Automated systems randomly dial numbers, and yours may have been included.
- Public Listings – Posting your phone number online (e.g., on social media or websites) makes it easier for scammers to find you.
Spam callers are persistent, but with the right measures, you can significantly reduce them.
1. Use the Built-in Spam Protection on Android
Most Android phones today come with built-in spam protection features. These features automatically identify suspected spam calls and warn you before you pick up.
How to Enable Spam Protection:
- Open the Phone app on your Android device.
- Tap the three-dot menu (top-right corner).
- Go to Settings > Caller ID & Spam.
- Toggle on See caller and spam ID.
- Toggle on Filter spam calls.
Once enabled, your phone will automatically block suspected spam calls or label them as “Spam” on the screen.
2. Block Specific Numbers Manually
If you keep receiving calls from the same number, the easiest solution is to block that number manually.
Steps to Block a Number:
- Open the Phone app.
- Go to Recents.
- Tap on the number you want to block.
- Select Block/Report Spam.
This prevents that number from calling or messaging you again.
3. Use Your Carrier’s Spam Call Protection
Many mobile carriers offer spam call filtering as part of their service. Depending on your carrier, you may get this for free or as a premium feature.
- T-Mobile – Scam Shield (free spam ID and blocking).
- Verizon – Call Filter (basic free plan, premium for advanced features).
- AT&T – Call Protect (free spam blocking).
- Google Fi – Built-in spam call blocking.
How to Activate:
Check your carrier’s official app (like My Verizon, My AT&T, or T-Mobile app) or dial their support number to enable spam protection.
4. Install Third-Party Spam Blocking Apps
If built-in tools aren’t enough, you can use third-party apps designed to stop spam calls. These apps use large databases and AI to detect spam numbers.
Best Spam Call Blocking Apps for Android:
- Truecaller – Popular for caller ID and spam blocking.
- Hiya – Identifies unknown numbers and blocks fraud.
- RoboKiller – Blocks robocalls and uses answer bots to waste scammers’ time.
- Call Control – Filters spam calls and text messages.
Tip: Make sure you download apps only from the Google Play Store for safety.
5. Enable “Do Not Disturb” Mode for Unknown Callers
If you only want to receive calls from people you know, you can use Android’s Do Not Disturb (DND) mode to silence unknown numbers.
How to Enable:
- Go to Settings > Notifications > Do Not Disturb.
- Customize Calls settings to allow calls only from Contacts or Favorites.
This way, unknown numbers won’t disturb you, but important contacts will still get through.
6. Register with the National Do Not Call Registry
If you’re in the United States, you can register your number with the National Do Not Call Registry. While it won’t block scammers completely, it helps reduce calls from legitimate telemarketers.
- Visit donotcall.gov to register for free.
- You can also call 1-888-382-1222 from the number you want to register.
7. Report Spam Calls
Reporting spam calls helps improve spam detection services.
Ways to Report:
- In the Phone app, tap Block/Report Spam after ending the call.
- Use third-party apps like Truecaller to report numbers.
- Contact your carrier and report the spam call.
The more users report, the better spam filtering gets.
8. Avoid Sharing Your Number Publicly
One of the best preventive measures is to protect your number.
- Don’t post your phone number on social media.
- Avoid giving your number on suspicious websites.
- Use a secondary number for online sign-ups.
Avoid Sharing Your Number Publicly
The fewer places your number appears, the harder it is for spammers to find you.
9. Block Spam Text Messages Too
Spam calls often come with spam text messages. Thankfully, Android lets you block those as well.
How to Block Spam Texts:
- Open the Messages app.
- Long-press the spam message.
- Tap Block/Report Spam.
You can also use apps like Google Messages or carrier-provided messaging apps to filter spam texts.
10. Reset Your Number (Last Resort)
If spam calls are overwhelming and nothing works, you may consider changing your number. While this is a last resort, it guarantees an end to current spam callers.
Be sure to:
- Notify important contacts about your new number.
- Avoid sharing your new number on unsafe platforms.
- Use Google Voice or a secondary number for public sign-ups.
FAQs About Stopping Spam Calls on Android
1. Can I stop spam calls permanently?
It’s nearly impossible to stop spam calls completely, but using multiple blocking methods can reduce them by 90%.
2. Are spam call blocking apps safe?
Yes, if downloaded from the Google Play Store. Avoid third-party APKs to protect your privacy.
3. Will blocking spam calls affect regular calls?
No, spam blocking only filters suspicious or unknown numbers. Your contacts can always reach you.
4. Why do spammers keep changing numbers?
Scammers use “spoofing” technology to create fake caller IDs, making it harder to track and block them.
5. Does airplane mode stop spam calls?
Yes, but it also blocks all calls and internet access, so it’s not a practical solution.
Final Thoughts
Spam calls on Android can be frustrating, but with the right combination of tools, settings, and apps, you can drastically reduce them. Start with your phone’s built-in spam protection, then add carrier services or third-party apps if needed. Always be cautious about sharing your number online, and report spam calls whenever possible.
By following these steps, you’ll enjoy a quieter phone experience with fewer interruptions from unwanted callers.
