Are you tired of getting calls from unknown numbers that you’d rather not answer? Well, if you’re an Android user, there’s a simple solution to silence those unwanted calls. By following a few easy steps, you can set your phone to automatically silence calls from numbers not in your contacts list. Let’s dive in and find out how to get some peace from those pesky unknown callers.

How to Silence Unknown Callers on Android

Before we get into the nitty-gritty, let’s quickly overview what we’ll be doing. We’re going to adjust your Android phone’s settings so that any calls from numbers not saved in your contacts will be silenced. This means your phone won’t ring, but you’ll still see missed calls in your call log if an unknown number tries to reach you.

Step 1: Open the Phone App

Open the Phone app on your Android device.

The Phone app is typically located on the home screen or in the app drawer. It’s the app you use to make calls, and it usually has a phone or receiver icon.

Step 2: Access Settings

Tap on the three dots in the top-right corner of the app and select ‘Settings’ from the dropdown menu.

These three dots are often referred to as the “more options” button, and it’s your gateway to customizing your call experience.

Step 3: Select ‘Blocked Numbers’

Scroll down and tap on ‘Blocked numbers’.

This section allows you to control which numbers are allowed to call you and which aren’t.

Step 4: Enable ‘Unknown Callers’

Toggle on the option that says ‘Block calls from unidentified callers’.

By enabling this feature, you’re telling your phone to automatically silence calls from numbers that aren’t in your contacts.

After you complete these steps, any calls from unknown numbers will go straight to voicemail without ringing. You’ll still be able to see missed calls from these numbers in your call log, and you can always turn off this setting if you’re expecting a call from a new number.

Tips for Silencing Unknown Callers

  • Keep your contacts list updated, so important calls don’t get silenced by accident.
  • Check your voicemail regularly, in case a legitimate call gets blocked.
  • If you’re expecting an important call from an unknown number, temporarily disable this feature.
  • Remember that some legitimate calls, like from doctors’ offices or delivery services, may come from unknown numbers.
  • You can always block individual numbers if you continue to receive unwanted calls from the same number.
