SpamBlocker

Block spam calls & SMS on Android 10+. Works alongside your existing dialer & SMS app.

Calls: Caller ID + call blocker. Identify, silence, or reject unwanted calls.

SMS - two modes:

1) Standalone (default): Intercepts notifications, filters spam, but messages stay in your SMS app. Custom notifications (sound, icon, LED, copy OTP).

2) Screening provider (advanced): Filters in real-time. Spam never appears in your SMS app. ONLY works with SMS apps that support screening protocol (e.g., Google Messages). Fewer permissions, limited RCS/MMS support.

After setup, system may kill the app. Disable battery optimization to keep it working 24/7.

Filters: Contacts, groups, prefixes, STIR/SHAKEN, repeated calls, dialed/answered numbers, emergency mode, Push Alert (notifications from other apps), SMS Alert, Recent Apps (e.g., pizza delivery), Meeting Mode, Off Time, offline spam database (DNC), geolocation, carrier, CNAP, Instant Query (real-time online lookup), Report Spam.

Regex (regular expressions) supported. Examples: .* (any number), .{0} (unknown/private), 789.* (starts with 789), .*123 (ends with 123), .{7} (7 digits), .*verification.* (contains word), .*(police|hospital).* (any of multiple words).

Limitations: No RCS/MMS, no auto SMS deletion, no local AI (planned), Android 10+ only.

Permissions (all optional): Internet, answer calls, notifications, read contacts, receive SMS/MMS, read call log/SMS, usage stats, ignore battery optimization, notification access, floating window, write settings, read logs.

Privacy: Offline = zero data. Online = IP, TLS/TCP fingerprint (Android version), reported number only. Disable internet or use offline APK.
