Block Guard FAQ

Spam calls have evolved, but so have the tools to fight them. As we enter 2026, relying on basic blocking features isn't enough. Here are five effective strategies to reclaim your peace and quiet.

1. Use a Dedicated Blocking App

While Android's default dialer has improved, it lacks granular control. Apps like Block Guard offer advanced filtering that goes beyond simple blacklists. With features like Strict Mode, you can ensure only your contacts can reach you, silencing everyone else instantly.

2. Register on the Do Not Call Registry

It’s the first line of defense. Adding your number to your country's National Do Not Call Registry reduces legitimate telemarketing calls, though it won't stop illegal scammers.

3. Silence Unknown Callers

If you don't recognize the number, don't answer. Answering signals to spammers that your line is active, leading to more calls. Block Guard automates this by letting you choose to "Silence" or "Reject" unknown numbers automatically.

4. Block Entire Area Codes

If you constantly receive spam from a specific region where you have no friends or business, block the entire area code. Block Guard makes this easy with its Area Code filtering feature.

5. Enable Spam Database Integration

Leverage community power. Block Guard integrates with updated spam databases to identify and block known malicious numbers before your phone even rings.

Have you ever received a call from a number that looks eerily similar to your own? It shares your area code and the first three digits (the prefix), but the last four digits are different. This is called Neighbor Spoofing.

Why Scammers Do It

Scammers know you are more likely to answer a local call or one that looks familiar. They "spoof" their caller ID to mimic your number structure, hoping you'll pick up thinking it's a neighbor, a local business, or a doctor's office.

The Solution: Intelligent Pattern Matching

Standard blockers struggle with this because the numbers are always changing. However, Block Guard features specific Neighbor Spoofing Protection. It analyzes incoming calls to detect this specific pattern (matching area code + prefix) and cross-references it with your contacts.

If a number mimics yours but isn't in your address book, Block Guard blocks it automatically. It’s the most effective way to stop these deceptive calls cold.

Aggressive blocking is great for peace of mind, but you can't afford to miss emergencies or important calls from work or family. That's where "Whitelisting" comes in.

The Problem with Standard DND

Android's built-in Do Not Disturb mode can sometimes be too broad or confusing to configure exceptions for. You might miss a delivery driver or a doctor's appointment because they aren't saved in your "Favorites."

The Block Guard Way

Block Guard simplifies this process. Our dedicated Whitelist feature overrides all active blocking rules, including Do Not Disturb schedules and Strict Mode.

• Easy Access: Add numbers directly from your contacts or call log.
• Total Bypass: Whitelisted numbers will ring through even if you have "Block All Unknown" enabled.
• Peace of Mind: Ensure your partner, kids, or boss can always reach you, no matter how high your security settings are set.

Don't leave important connections to chance. Take control of your exceptions list with Block Guard.
