What an Android Call Blocking App Needs to Work Well
Android call blocking works best when the app has the right permissions and the rules match your real life. Block Guard uses the permissions you grant during setup to screen calls and filter texts according to the controls you choose.
Permissions are part of the setup
Call and SMS permissions are what let a call blocker do its job. Block Guard asks for the access it needs during setup, then you decide which blocking rules should be active.
Rules should be practical
A useful Android blocker needs more than an on/off switch. Start with contacts and whitelists, then tune private-number rules, unknown-number handling, area-code rules, prefix rules, schedules, and profiles.
Logs help avoid mistakes
Blocked-call logs are how you catch rules that are too strict or too weak. Check them during the first week and make small adjustments instead of guessing.
