Call Shield: Spam Call Blocker

Call Shield: Block Unwanted Calls and Safeguard Your Privacy Take control of incoming calls with Call Shield — a powerful app that blocks known robocallers, telemarketers, and other unwanted callers using a secure, local blocklist that operates entirely on your device. Key Features: - Block Unwanted Calls: Block specific numbers or entire number ranges (prefixes) to reduce spam and robocalls. Supports up to 200 million blocked numbers across multiple extensions. - Offline Functionality: Fully offline operation. No login required, and no data is transmitted — your privacy stays protected. - Easy to Use: Simple setup and intuitive interface for quickly managing your blocklist. Important Notes: - Voicemail Handling: Blocked calls may still be forwarded to voicemail, depending on your mobile carrier’s policies. Contact your carrier for details. - Do Not Disturb Mode: If Do Not Disturb mode is active, blocked calls may still appear silently on your Home screen or in Recents. Disable Do Not Disturb for full blocking functionality. - Extension Setup: If Call Shield extensions don't appear immediately after updating prefixes, open Settings > Phone > Call Blocking & Identification to verify they are enabled. Privacy Policy: Call Shield does not collect, store, or transmit any personal data or call history. All blocking is handled locally on your device.
