How to Stop Spam Calls on Android: Settings Your Parents Need Turned On

Your father's Samsung has become a magnet for scam calls. He answers every one because he doesn't know how to tell the difference between a real call and a robocall. Last month, he spent 20 minutes on the phone with someone claiming to be from "the tax department" before your mother overheard and grabbed the phone.

Android phones actually have excellent built-in tools to filter spam calls — but they're buried in settings menus that most seniors will never find on their own. Here's how to set everything up in about five minutes.

Turn on Google's Caller ID and Spam Protection

Google has built a spam detection system directly into the Phone app on most Android devices. It screens calls against a database of known spam numbers and flags them before your parent ever sees the phone ring.

1. Open the Phone app (the green phone icon)
2. Tap the three dots (menu) in the top right
3. Tap Settings
4. Tap Caller ID & spam
5. Toggle on See caller and spam ID
6. Toggle on Filter spam calls

When "Filter spam calls" is enabled, calls identified as spam won't ring at all. They'll be sent to voicemail silently. Your parent won't see a missed call notification — the spam call just disappears.

This feature works on Google Pixel phones, most Samsung devices, and most other Android phones that use the Google Phone app. If your parent's phone uses a different dialer (some older Samsung models use their own), see the Samsung-specific instructions below.

Samsung-specific: turn on Smart Call and Block Unknown Numbers

Samsung phones have their own caller ID system alongside Google's:

1. Open the Phone app
2. Tap the three dots > Settings
3. Tap Caller ID and spam protection and toggle it on
4. Go back to Settings and tap Block numbers
5. Toggle on Block unknown/private numbers

The "Block unknown/private numbers" setting is Samsung's equivalent of Apple's "Silence Unknown Callers." It sends calls from numbers not in your parent's contact list to voicemail without ringing.

If your parent has a newer Samsung (Galaxy S24 or later), they may also have access to Samsung's AI-powered call screening, which can answer suspected spam calls and ask the caller to identify themselves before the phone rings.

Block specific repeat callers

When a scam number calls more than once:

1. Open the Phone app
2. Tap Recents (or Call Log)
3. Long-press the scam number
4. Tap Block number (or Block/report spam)

On Samsung devices, you can also tap the number, then tap Details > Block.

Blocked callers can't ring, text, or leave a voicemail. If you want them to still be able to leave a voicemail (useful if you're worried about blocking a legitimate caller by mistake), use the "Filter spam calls" method above instead — it silences the ring but lets voicemail through.

Set up Do Not Disturb with contact exceptions

For parents who get anxious about missing calls, Do Not Disturb mode offers a middle ground. It lets calls from saved contacts through while silencing everything else:

1. Go to Settings > Notifications (or Sound & vibration)
2. Tap Do Not Disturb
3. Under Calls, select Contacts only (or Starred contacts only for an even tighter filter)
4. Turn on Do Not Disturb

You can also schedule Do Not Disturb to turn on automatically during certain hours — for example, from 6 PM to 8 AM, when evening scam calls are most common and most distressing.

Use Google's Call Screening (Pixel phones)

If your parent has a Google Pixel phone, they have access to Google's Call Screen feature — one of the best spam defenses available on any phone. When an unknown number calls:

1. Your parent sees a "Screen call" button on the incoming call screen
2. Tapping it makes Google Assistant answer the call and ask who's calling and why
3. Your parent sees a real-time transcript of the caller's response on screen
4. They can then choose to answer, hang up, or mark as spam — without ever speaking to the caller

This is particularly powerful for seniors because it removes the social pressure of being on the line with a stranger. They never have to talk to the scammer at all.

To make sure it's enabled: Open Phone > three dots > Settings > Call Screen and follow the setup prompts.

Add important contacts before enabling blocking

Before you turn on any call-blocking features, spend 10 minutes updating your parent's contact list. Make sure it includes:

• Doctor's offices and specialists
• Pharmacy
• Bank (use the number on the back of their card)
• Insurance companies
• Close friends and neighbors
• All family members
• Home repair and service providers they use regularly

Any caller not saved as a contact will be silenced or blocked, depending on which settings you enable. A complete contact list ensures that the people your parent actually wants to hear from can always get through.

The 5-minute Android setup checklist

Here's the quick-reference version to run through next time you have your parent's phone:

• [ ] Turn on Caller ID and Spam Protection in Phone settings
• [ ] Turn on Filter Spam Calls (Google) or Block Unknown Numbers (Samsung)
• [ ] Block any recent scam numbers in the call log
• [ ] Add all important contacts (doctors, bank, pharmacy, family)
• [ ] Set up Do Not Disturb with contacts-only exceptions
• [ ] If Pixel: enable Call Screen

These settings work together to create multiple layers of protection. Even if a scammer gets past Google's spam filter, Do Not Disturb ensures the phone doesn't ring unless the caller is someone your parent knows.

Phone settings are your first line of defense

Configuring your parent's Android phone to block spam calls is one of the highest-impact, lowest-effort things you can do to protect them from phone scams. Most scam calls are volume operations — they call thousands of numbers hoping a few people answer. When your parent's phone doesn't ring, the scammer moves on to the next target.

But phone settings can't stop every threat. Scammers also use text messages, email, and social media. And some calls do get through — spoofed numbers that look like they're from the local area code, or calls that appear to come from a bank or government agency.
