What is call screening?

The first two are about you deciding. The third is the carrier deciding for you. Most people asking "what is call screening" have just seen the second kind for the first time, because it arrived on iPhone in 2025.

When a number that isn't in your contacts calls, the phone picks up before you hear anything. A synthetic voice says something like "Please tell me your name and the reason for your call." The caller answers, the phone transcribes what they said, and then it rings you, with the transcript on the lock screen.

You can pick up, decline, or on Pixel tap canned replies ("I'll call you back", "Report as spam"). If the caller hangs up instead of answering, you never hear a ring at all, which is what happens to most robocalls, since an autodialer can't answer a question.

The important detail is who gets screened. On both platforms it's unknown numbers only: anyone in your contacts, and on iPhone anyone you've recently called or texted, rings through normally. Screening doesn't touch the people you already know.

• iPhone (iOS 26 and later): Settings, then Apps, then Phone, then Screen Unknown Callers, and choose Ask Reason for Calling. The other options are Never (ring everything) and Silence (straight to voicemail, the old iOS 13 behavior). Step-by-step in how to turn on call screening on iPhone.
• Google Pixel: open the Phone app, tap the three-dot menu, then Settings, then Spam and Call Screen, then Call Screen, and pick a protection level for unknown callers. Step-by-step in how to turn on call screening on Android.
• Other Android phones: most don't have automatic screening built in. The Phone app's caller ID and spam protection plus your carrier's filtering app is the equivalent. Samsung has added comparable screening on some recent Galaxy models; check the Phone app's settings for a screening or call-assist option.
• Google Voice: Settings, then Calls, then Call screening.

"I'm screening my calls" means the person is looking at who's calling and choosing not to answer some of them, usually because they're avoiding someone or avoiding spam. "Your call was screened" from an assistant or receptionist means they asked who you were and what it was about before deciding whether to put you through. The phrase is the same whether a person or a phone is doing it.

On a screened call you may hear a short recorded prompt asking for your name. Answer it plainly, with your name and one sentence on why you're calling. A caller who hangs up at the prompt is treated as spam; a caller who answers gets through.

Screening is built for personal phones, where an unanswered unknown number costs nothing. On a business line, every unknown number might be a customer, and the screening prompt is the first thing they hear.

Some will answer it. Many won't. A homeowner calling three plumbers, or a patient calling two dentists, is not going to explain themselves to a robot before a human picks up; they'll hang up and dial the next listing. You'll never see those calls, because screening logs them as a caller who didn't respond, indistinguishable from a robocall.

The better shape for a business is the opposite of screening: answer everything, then sort. An AI receptionist picks up every call, greets the caller like a receptionist would, finds out what they need, books the appointment or takes the message, and sends you a summary. Robocalls get nowhere because there's no human to press 1 for; real callers get helped. You get the filtering that screening promises without the hang-ups it causes. Our guide to blocking spam calls covers the carrier-level filtering that pairs with it.
