Stop robocalls on Android

Robocalls are automated spam calls that try to sell you something, steal information, or trick you into calling back. Android has a few built-in options, but most users still need a stronger layer of protection.

What actually works to stop robocalls

1. Block known spam numbers — add repeat offenders to your blocklist.
2. Use a call blocker that can handle spoofed and “local-looking” numbers (neighbor spoofing).
3. Whitelist important contacts so your family, doctor, and work calls always get through.
4. Silence unknown callers when you’re busy — but keep emergency/whitelisted numbers allowed.
5. Report and refine — the best systems learn from the calls you mark as spam.

Quick setup

1. Install Block Guard from Google Play.
2. Enable the permissions the app requests (needed to identify/block calls).
3. Add your must-allow contacts to the whitelist.
4. Turn on the protections you want (spam/scam, spoofing, unknown callers).
