Spam call blocking
A Spam Call Blocker App That You Can Tune
Spam callers keep changing numbers. Some are automated, some are live, and some use local-looking caller IDs to get you to answer. Block Guard helps Android users reduce those interruptions with layered rules instead of relying on one blacklist.
Block more than one type of unwanted caller
Use Block Guard for spam calls, scam calls, robocalls, private numbers, unknown callers, suspicious area codes, repeat prefixes, and unwanted text messages. The app is strongest when you combine multiple signals.
Keep real callers reachable
Strict spam blocking can create problems if important unknown calls matter to you. That is why trusted contacts, whitelists, profiles, and blocked-call logs are important parts of the setup.
Improve the setup after a few days
Start with moderate protection, then review blocked activity. If unwanted calls repeat from similar numbers, create a targeted rule. If a real number gets caught, whitelist it.
