In this tutorial, you will learn how to:
• Block or unblock recent callers
• Manage blocked numbers through Settings
Â
You cannot block an Unknown Caller (No Caller ID), but you can turn on Do Not Disturb manually and set it to "Only allow calls from your contacts list." The call blocking feature may not affect phone calls made or received via third-party apps installed on your device. Please contact third-party app developers for assistance with such applications.
