The fake “your package is stuck” text. The call from “your bank’s fraud team.” The order confirmation for a TV you never bought. November and December bring all three, and they show up right when you’re expecting real deliveries and real charges.
Good news first. Your phone probably has more protection built in than you think. Bad news? Some of it ships switched off, some only works on certain models, and some only works in certain countries. So it’s worth ten minutes on a quiet evening before Black Friday to check.

Android: start with the Phone app
Most of Google’s call protection lives in the Phone by Google app. Catch: the smartest pieces are Pixel features, not Android ones. A Samsung or Motorola phone may have its own versions, or none.
Scam Detection for calls (Pixel only). This one listens for patterns common in scam calls while the call is happening, and if it spots one, your phone buzzes, beeps and shows an alert. It’s off by default. To turn it on: Phone app, then More, then Settings, then Scam Detection. Google’s help page says it works on Pixel 6 and later in the US, and on Pixel 9 and later in a list of other countries that includes Canada, the UK, Australia and India. You need a SIM from a listed country, and you need to be in that country.
The phone plays a beep at the start of the call and every few minutes after, so the other person knows the feature is on. And Google says the processing happens on the device, with no audio or transcript stored or sent to Google. It also says, plainly, that it won’t catch every scam call.
Call Screen (Pixel). Different tool. Call Screen answers suspicious calls for you and asks who’s calling, and on automatic mode it can hang up on spam. Automatic screening works on Pixel phones in the US, Canada, the UK, Ireland and Australia. Path: Phone app, More, Settings, Spam and Call Screen (or just Call Screen), then Call Screen. Calls from your contacts aren’t screened, and automatic screening doesn’t run while you’re roaming.
Caller ID and spam (Phone by Google on other Androids too). In the same settings menu, “See caller ID & spam” is on by default. No automatic Call Screen on your model? Look for “Filter spam calls.” Suspected spam stops ringing but still shows up in your call history.
Android: texts and chat apps
Google Messages spam protection. On by default, according to Google. Worth a peek anyway. In the app, tap your profile picture, then Messages settings, Protection & Safety, Spam protection; “Enable spam protection” should be on. Know the trade: to check links, Messages uploads the URL to Google.
Google added scam detection to Messages for conversations with people who aren’t in your contacts, starting in English in the US, UK and Canada. That’s the “package fee” and “wrong number, let’s be friends” crowd.
Coming soon, maybe. Google Messages is also rolling out an optional Enhanced protection mode. If it appears on your phone, it switches on stronger scam and link checks, with suspicious chats from unknown senders analyzed in Google’s Private AI Compute.
Scam Detection for chat notifications. Newer. It scans notifications from many popular messaging apps and flags a likely scam with a red warning. The feature launched on Pixel, but Google announced an expansion to hundreds of millions of additional Android users later in 2026, with makers like Motorola, OnePlus, Xiaomi, HONOR, OPPO and vivo. Availability varies by manufacturer, device, country and rollout status. On a Pixel it’s on by default: Settings, Security & privacy, More security & privacy, Scam Detection, then “Message scams.” One quirk: it reads new message notifications, so it won’t warn you while you’re already inside the app.
Android: the protections you don’t switch on
During a phone call, Android blocks a few moves scammers love. You can’t turn off Google Play Protect mid-call (Android 6 and up). On Android 16 devices you also can’t install an app for the first time from a browser or messaging app, or grant accessibility permissions, while you’re on a call. If a “tech support” caller asks you to do exactly that and your phone refuses? Good. That’s the point.
Then there are verified financial calls, announced in May 2026 for Android 11 and up. When a call claims to be from your bank, Android can ask that bank’s app (if it’s installed and you’re signed in) whether the bank is really calling, and end the call if it isn’t. Verified financial calls now works with participating financial institutions including Itaú, Banco do Brasil and Revolut, with additional partners being added. Nubank was named at launch, too. Since June, Google says, it has blocked more than 3 million spoofed calls from Banco do Brasil and Itaú alone. The catch for US readers? Availability still depends on the bank and device, and yours may not take part yet.
Google also said Live Threat Detection, which watches for apps acting suspiciously, gets new checks on Android 17 devices in the second half of 2026, on select devices.10:41

iPhone: the Phone app settings
Apple folded a lot into one menu in iOS 26. Go to Settings, then Apps, then Phone, and scroll to Screen Unknown Callers. Three choices:
- Never: unknown numbers ring like normal.
- Ask Reason for Calling: your iPhone asks the caller why they’re calling before your phone rings. This is Call Screening.
- Silence: unknown numbers go straight to voicemail.
I’d pick Ask Reason for Calling for the holiday stretch. Delivery drivers and the pharmacy can still get through; a robocall usually has nothing to say.
Limits, per Apple. Call Screening only works in certain languages and regions; in the US, that’s English and Spanish. Calls aren’t screened while you’re roaming. If you call emergency services, screening turns off for 24 hours.
Same Phone settings page, under Call Filtering: you can turn on Unknown Callers (missed calls and voicemails from unknown numbers go to their own list) and the spam filter.
iPhone: Messages and the newer stuff
Screen Unknown Senders. In iOS 26, it’s off by default. (If you had Filter Unknown Senders on in iOS 18, it carried over.) Turn it on in Messages: tap Filters, then Manage Filtering. Or Settings, Apps, Messages, then Unknown Senders. Texts from numbers you don’t know go to a separate list. Verification codes still notify you by default, and in the US you can choose which other kinds of messages from unknown senders can notify you.
Impersonation Risk Detection (iOS 27). New, and easy to misread. No, it won’t read your texts. Apple says it never analyzes what’s in your Messages, Photos or Mail. The actual job: you start a payment or an account change inside a supported app, and your iPhone hands that app a risk level of Unknown, Medium or High. Then the app decides. Warn you, slow things down, ask for extra verification. To flip it on, go to Settings, Privacy & Security, Impersonation Risk Detection, and toggle Share with App Developers. And “Unknown” doesn’t mean safe.
Stolen Device Protection. Crowded malls, a phone in a back pocket. You see where this goes. On iOS 17.3 or newer, find it under Settings, Face ID & Passcode. Once you’re away from places your iPhone knows, sensitive changes want Face ID or Touch ID, and some sit behind a one-hour wait.
| iPhone feature | What it does | Where to find it | Availability (as of October 2026) |
|---|---|---|---|
| Screen Unknown Callers: Ask Reason for Calling | Asks unknown callers why they’re calling before your phone rings | Settings > Apps > Phone > Screen Unknown Callers | iOS 26+; select languages and regions (US: English, Spanish); not while roaming |
| Screen Unknown Callers: Silence | Sends unknown numbers to voicemail | Same menu | iOS 26+ |
| Call Filtering: Unknown Callers and spam | Moves unknown and spam calls to separate lists | Settings > Apps > Phone > Call Filtering | Current iOS |
| Screen Unknown Senders | Moves texts from unknown numbers to a separate list | Messages > Filters > Manage Filtering, or Settings > Apps > Messages | iOS 26+; off by default |
| Impersonation Risk Detection | Gives supported apps a scam risk level for risky actions | Settings > Privacy & Security > Impersonation Risk Detection | iOS 27+; supported apps only |
| Stolen Device Protection | Biometrics and a security delay for sensitive changes away from familiar places | Settings > Face ID & Passcode | iOS 17.3+ |
Don’t skip theft protection on Android
A snatched, unlocked phone is a scam waiting to happen. Settings, Google, All services, Theft protection. Inside: Theft Detection Lock (locks the screen if it senses someone grabbing the phone and running), Offline Device Lock, Remote Lock at android.com/lock, and on certain devices Identity Check. Google says support varies by model, and theft protection isn’t available on Android Go devices or tablets. If a toggle is grayed out or missing, your phone doesn’t support it.

Your carrier has a free layer too
All three major US carriers offer free spam call tools, with paid upgrades you don’t need for the basics.10:41
| Carrier | Free tool | Paid tier (as of October 2026) |
|---|---|---|
| AT&T | ActiveArmor: fraud and spam call blocking, free with AT&T wireless plans (app needs iOS 16.4+ or Android 10+) | ActiveArmor advanced, $7/month |
| Verizon | Call Filter: spam detection, spam filter, spam reporting, for standard monthly and prepaid plans on compatible devices | Call Filter Plus, $3.99/month |
| T-Mobile | ScamShield: Scam Likely labels, Scam Block (dial #662#), spam calls to voicemail | ScamShield Premium, $4/month per line |
10:41
AT&T and T-Mobile both warn that blocking can catch calls you want. So check voicemail.
What none of these do
They don’t stop you from calling a scammer back. They don’t verify a caller who uses a real, unspoofed number with a good story. And none is perfect. Google and AT&T say so outright.
The FTC’s advice still does the heavy lifting: caller ID can be faked, government agencies don’t call to demand payment, and anyone insisting on gift cards, wire transfers or crypto is a scammer. If “your bank” calls, I’d hang up and dial the number on the back of my card. Cloned voices are their own problem; our guide to AI voice cloning scams covers the family-emergency version, and gift card scams get their own breakdown.

Frequently Asked Questions
Does my Samsung phone get Pixel Scam Detection?
Not according to Google’s help pages, which list Pixel phones only for call Scam Detection. Samsung and other brands may have their own tools; Google Messages spam protection and the in-call protections aren’t Pixel-only. The chat notification version is expanding to other makers, though Samsung isn’t on Google’s list.
Will Call Screening on iPhone block calls from my doctor or a delivery driver?
It doesn’t block them. It asks unknown callers why they’re calling before your phone rings. Save numbers you care about in Contacts and they ring normally.
Is the Pixel listening to my calls?
Per Google, call Scam Detection runs on the device only. No audio or transcript gets stored or sent, and a beep tells both sides it’s on.
Do I need to pay for my carrier’s spam blocker?
No, for the basics. AT&T, Verizon and T-Mobile all have free tiers. Paid add-ons are extras; T-Mobile’s, for one, adds reverse number lookup.
My bank called and the Android check didn’t flag it. Is it real?
Maybe, maybe not. Verified financial calls only works with participating banks, and your bank may not be one of them yet. Hang up and call the number on your card.
