How to Screen Unknown Callers on Your Phone Today

Receiving calls from unknown numbers can be a nuisance, often leading to unwanted interruptions or potential scams. Fortunately, both iPhone and Android devices offer built-in features to help you manage these calls effectively.

How Can I Screen Unknown Callers on My iPhone?

Apple provides several options to handle calls from unknown numbers:

1. Silence Unknown Callers

This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions, sending them directly to voicemail. To enable it:

  • Open Settings.
  • Tap Phone.
  • Toggle on Silence Unknown Callers.

This method is effective but may cause you to miss important calls from numbers not saved in your contacts. (support.apple.com)

2. Screen Unknown Callers

Introduced in iOS 26, this feature prompts unknown callers to state their name and the reason for calling before your phone rings. To activate it:

  • Go to Settings.
  • Tap Phone.
  • Under Screen Unknown Callers, select Ask Reason for Calling.

When an unknown number calls, your iPhone will ask them to state their name and purpose. Their response is transcribed and displayed on your screen, allowing you to decide whether to accept, decline, or send the call to voicemail. This feature helps filter out robocalls and scammers effectively. (techradar.com)

3. Call Filtering

You can also filter calls from unknown numbers by moving them to a separate list:

  • Open Settings.
  • Tap Phone.
  • Under Call Filtering, enable Unknown Callers.

Missed calls and voicemails from unknown numbers will be moved to your Unknown Callers list, which you can access in the Phone app. (support.apple.com)

How Can I Screen Unknown Callers on My Android Phone?

Android devices offer various methods to manage calls from unknown numbers:

1. Block Calls from Unknown Numbers

This option blocks calls from numbers that do not display a caller ID. To enable it:

  • Open the Phone app.
  • Tap the three-dot menu (⋮) and select Settings.
  • Tap Blocked Numbers.
  • Toggle on Unknown.

This will block calls from private or unidentified numbers. (howtogeek.com)

2. Use Call Screening Features

Some Android devices, like Google Pixel, offer call screening features:

  • Open the Phone app.
  • Tap the three-dot menu (⋮) and select Settings.
  • Tap Call Screen.
  • Choose your preferred option:
  • Ring Phone: Default setting.
  • Automatically Screen: Declines robocalls.
  • Silently Decline: Silently declines calls from unknown numbers.

When Automatically Screen is enabled, Google Assistant answers the call and determines if it's a robocall or spam, hanging up if it is. (makeuseof.com)

3. Use Third-Party Apps

For enhanced call screening, consider third-party apps like Robokiller. Robokiller identifies and blocks spam calls, providing real-time alerts and detailed reports. It offers a comprehensive solution to manage unwanted calls effectively.
