🚨 Why Secure Incoming Calls?
Even if your phone is locked, your calls may still be exposed in ways like:
- Others answering your calls when your phone rings unattended
- Spam & scam calls faking familiar numbers (spoofing)
- Call popups showing private names/details on lock screen
- Unsecured third-party call apps leaking metadata
In 2025, AI call bots and scam networks are smarter—they can trick users into answering by mimicking real contacts. So call security is no longer optional—it’s essential.
✅ How to Secure Incoming Calls on Android (2025)
🔐 1. Disable Call Popup on Lock Screen
- Go to Settings → Notifications → Lock Screen
- Set to “Don’t show sensitive content”
- Or go to Phone App > Notifications → Turn off Lock Screen Popups
This hides the caller’s name and number when your phone is locked.
🔐 2. Use App Lock for Phone Dialer
Protect the Phone app with a password or fingerprint.
Best Apps for This in 2025:
- Norton App Lock (Free)
- Smart AppLock
- AppLock by DoMobile
Steps:
- Install AppLock from Play Store
- Add Phone or Dialer app to the lock list
- Choose PIN, pattern, or fingerprint
Now no one can answer or view your call log without your permission.
🔐 3. Enable Caller ID & Spam Protection
- Open Phone app
- Tap ⋮ > Settings > Caller ID & Spam
- Enable:
- Filter spam calls
- Verified Calls (Google)
This reduces spam and shows business caller verification badges for legit numbers.
📲 Secure Incoming Calls on iPhone (iOS 17+)
🔐 1. Hide Caller Info on Lock Screen
- Go to Settings → Notifications → Phone
- Tap Show Previews → Select “When Unlocked”
- Caller ID will now be hidden unless you unlock the phone
🔐 2. Use Screen Time to Lock the Phone App
- Settings → Screen Time → App Limits
- Set limit for the Phone app (e.g., 1 min/day)
- Enable Passcode on Screen Time
This restricts access to calls unless you enter your Screen Time PIN.
🔐 3. Silence Unknown Callers
- Settings → Phone → Silence Unknown Callers
- Enables AI filtering:
- Rings silently
- Sends directly to voicemail
- Still shows in Recents
Perfect to block unknown numbers, spoofed calls, or scammers.
