“You can reduce the interruptions from unknown callers by sending them directly to voicemail. This cuts down on spam or robocalls and stops you from receiving alerts while on another call.” Call Silencing is enabled by default for most users but if it’s not, here’s how: On your device open Settings > Phone Info (or ringtone) & select “Censor Unknown Number” where available at bottom of page; tap/checkbox next too option (“Also,” decline)?
- Open your Settings app.
- Tap Phone.
- Tap Silence Unknown Callers.
- Tap the slider so it is ON/OFF.
