This life-changing feature screens calls from any number that is not currently in your contacts. The caller is asked for their name and reason for calling, and their response is shown on your iPhone, along with the option to answer or decline the call.
To enable it go to: Settings > Apps > Phone
- Screen Unknown Callers > Select: Ask Reason for Calling
- Call Filtering: Enable both Unknown Callers & Spam
Missed calls from unknown numbers will be filtered out of your recent call history. To access these, you will need to tap the blue hamburger menu at the top and select Unknown Callers.
