  • Step 2: Navigate to the 'Recents' tab to view your call history. Find the number you wish to block.
  • Step 3: Tap on the number or contact name to open the call details. Look for the 'i' icon (information icon) next to the number.
  • Step 4: Tap on the 'i' icon, and then select 'Block number' or 'Block/report spam' from the options presented.
  • Step 5: Confirm the action by tapping 'Block' when prompted. You should see a confirmation message indicating that the number has been blocked.
  • Step 6: To verify, return to the 'Recents' tab and check if the number is no longer able to call you.

  • Step 3: Tap on the number, then tap 'More' (three dots) and select 'Block number'.
  • Step 4: Confirm the blocking action.

Method 2: Blocking a Number via Settings

Use this method if you prefer to block numbers through the settings menu, which allows you to manage blocked numbers more comprehensively.
  • Step 1: Open the Settings app on your device.
  • Step 2: Scroll down and select 'Network & internet' or 'Connections', depending on your device.
  • Step 3: Tap on 'Call' or 'Phone' settings.
  • Step 4: Look for 'Blocked numbers' or 'Call blocking' and tap on it.
  • Step 5: Tap on 'Add a number' or the '+' icon, then enter the number you wish to block.
  • Step 6: Confirm by tapping 'Block' or 'OK'. You should see the number listed under blocked numbers.

  • Error: 'Unable to block number' - Solution: Ensure you have the latest version of your Phone app and that your device is updated.
