How to Block Spam Calls on Android in 2026
Blocking spam calls on Android in 2026 has become more streamlined thanks to advanced AI, carrier-level protections, and built-in OS features. Here’s how to stop unwanted calls for good.
Step-by-Step Guide to Block Spam Calls on Android (2026)
1. Enable Google Phone App’s Built-In Spam Protection
Google’s Phone app (pre-installed on most Pixel and many other Android devices) now uses on-device AI to identify and block spam calls in real time.
Steps:
- Open the Phone app (green icon with a white phone).
- Tap the three-dot menu (⋮) in the top-right corner.
- Select Settings → Spam and Call Screen.
- Toggle See caller & spam ID to On.
- Toggle Filter spam calls to On (this automatically silences and sends spam calls to voicemail – or blocks them entirely, depending on your Android version).
- Under Call Screen, choose Protection level: select Maximum (new in Android 16/17) to have the AI ask the caller to state their name before the call even rings your phone. Spam callers usually hang up at this prompt.
Note: In 2026, Google’s on-device AI can detect newer spam tactics like voice cloning. Ensure your Google Phone app is updated via the Play Store.
2. Activate Carrier-Level Call Filtering
Every major U.S. carrier now offers free or premium spam blocking baked into the network. These filters work before the call reaches your phone.
For T-Mobile / Metro:
- Open the T-Mobile app or dial #632#.
- Follow prompts to enable Scam Shield (free tier automatically blocks known scammers).
- For extra control, install the Scam Shield app and set blocking to Block All Scam Calls.
For Verizon:
- Open the Verizon Call Filter app (pre-installed on most Verizon phones).
- Tap Get Started → enable Spam Filter (free). The paid version adds caller ID and risk-level icons.
- Alternatively, go to Settings → Phone → Call Blocking & Identification and check Verizon Call Filter to enable network-level blocking.
For AT&T:
- Install the ActiveArmor app from the Play Store.
- Sign in with your AT&T account and turn on Call Protection (free) – it blocks high-risk spam calls and labels lower-risk ones.
- In the app’s settings, enable Automatic Fraud Blocking – this will stop calls flagged as fraud before they ring.
For smaller carriers (Mint, Visible, etc.):
- Check your carrier’s app or dial a short code (e.g., #662# for Mint, #ONESTEP for Cricket). Most now offer a free spam-blocking tier.
3. Block Unknown Numbers Directly from Android’s Do Not Disturb
Android 16 and 17 include a refined “Silence Unknown Callers” feature that sends any number not in your contacts straight to voicemail without ringing.
Steps:
- Open Settings → Phone (or search “Silence Unknown Callers” in Settings).
- Tap Silence Unknown Callers.
- Toggle the switch to On.
- (Optional) Go to Do Not Disturb → Calls → Allow calls from and select Contacts only. This ensures only saved numbers ring through even when DND is off.
Important: This method blocks legitimate calls from new people (delivery drivers, doctors) – they should leave a voicemail. If you’re expecting an important call from an unknown number, temporarily disable this setting.
4. Report Spam Calls to Google and Your Carrier
Reporting spam calls helps improve the blocking database for everyone and can trigger automatic blocking for your number.
How to report via Google Phone app:
- After a spam call rings (or appears in your call log), tap the call entry.
- Scroll down and tap Block / Report spam.
- Check the box Report call as spam (Google will anonymize the data and share it with carriers).
- Tap Block.
How to report via carrier app:
- In T-Mobile Scam Shield, swipe left on any call entry and tap Report.
- In Verizon Call Filter, tap the call entry, then Report Spam.
- In AT&T ActiveArmor, open the call log, tap the call, and select Report as Spam.
5. Use Third-Party Call Blockers (If Needed)
If built-in tools aren’t enough, a single third-party app can add an extra layer. Hiya (free) and Truecaller (free with ads) remain the most reliable in 2026, with on-device AI that works offline.
Steps for Hiya (recommended for 2026):
- Install Hiya from the Play Store.
- Open the app and grant Phone and Contacts permissions.
- Tap Enable Caller ID & Spam Blocking. The app will configure itself as your default call screen.
- Inside Hiya, go to Settings → Blocking → toggle Block Spam Calls.
- (Optional) Enable Community Blocking – this uses crowd-sourced data to block new spam numbers within seconds.
Caution: Avoid apps that require “read all calls” or “access to your SMS” unless you trust the developer. Stick to Hiya or Truecaller’s free tier.
6. Leverage Android 16/17’s Enhanced Scam Detection
Android 16 (released in 2025) and Android 17 (2026) introduced Live Scam Detection – an AI that listens to the call in real time and warns you if the conversation sounds like a scam.
To enable (Pixel 8 and newer, plus select Samsung Galaxy S25+):
- Open Settings → Safety & emergency → Scam Detection.
- Toggle Scam call alerts to On.
- When a call comes in, the system can also show a “Potential scam” pop-up mid-conversation, with an option to hang up and block immediately.
For Samsung phones (One UI 7.x):
- Open Phone app → three dots → Settings → Block numbers → Smart Call → enable Auto block spam and Identify scam calls.
- Under Call settings, toggle Block unknown callers if you want.
Conclusion
Blocking spam calls on Android in 2026 requires a layered approach. Start by turning on Google’s spam filter and the built-in silence-unknown-callers feature. Then activate your carrier’s free call-blocking tool – this stops calls at the network level. For persistent spam, add a trusted third-party app like Hiya. Finally, keep your phone’s AI-powered scam detection enabled. With these steps, you can reduce spam calls to nearly zero and only hear from people you actually want to talk to.
FAQ
Q1: Does blocking a number also block text messages from that number?
No – call blocking only affects voice calls. To block SMS spam, use the Messages app and tap Block on any spam text, or enable Spam Protection in Messages settings.
Q2: Will enabling spam filters prevent emergency calls from reaching me?
No. Emergency calls (from hospitals, police, or public safety numbers) are never blocked by any spam filter or “silence unknown callers” feature.
Q3: I’m still getting spam calls after following all steps – what now?
Make sure all your apps (Phone, carrier app, and any third-party blocker) are updated to the latest version. If spam persists, submit a report to the FCC’s Do Not Call Registry (donotcall.gov) – repeat offenders may face fines.
Q4: Is it safe to give a third-party call blocker access to my call log?
Reputable apps like Hiya and Truecaller process data on-device and do not upload your call log. However, read the privacy policy carefully. If you’re uncomfortable, stick to built-in Android and carrier tools.
Q5: How do I unblock a number I accidentally blocked?
Open the Phone app → three-dot menu → Settings → Blocked numbers. Find the number and tap the X or Unblock next to it.
Q6: Does Android’s Live Scam Detection record my calls?
No. The AI processes the audio in real time on your device and never stores or sends recordings. The feature can be disabled at any time in Settings.
