How to recognize spam or scam calls on your phone

First: check which option you're looking for

In the app Google Phone, go into More options > Settings > Caller ID and spamIt should appear there. View caller ID and spam IDIf activated, the phone can display information about numbers you haven't saved and warn you of potential spam calls.

Google also describes a fake call detection which can alert you when someone is hiding their identity or trying to impersonate one of your contacts. However, its setup instructions don't indicate that you need to turn on another button with that exact name. Therefore, Not finding that name in the menu does not necessarily mean that a function is missing..

Don't confuse this protection with Filter spam callsThat second setting prevents certain calls classified as spam from interrupting you; it's not the name of the phishing detection system.

Check Android, installed apps, and RCS

To detect potential scam calls, Google lists stricter requirements than for basic spam identification. Let's review them one by one:

• System version: Your phone must have Android 12 or later. You can check this in Settings, under About phone, or the equivalent section on your manufacturer's website.
• Required apps: Google Phone, Google Contacts, and Google Messages must be installed.
• RCS Chats: They must be enabled in Google Messages. Open that app, tap your profile picture, go to Message Settings, and check the RCS Chats section.

If any of these elements are missing, your mobile phone may still display certain spam warnings, but failure to meet documented requirements for the detection of false callsMake sure your apps are updated from Google Play before checking again.

The fact that Google Contacts is required doesn't mean you have to enable special synchronization of your entire address book. Google notes that caller ID and spam are not included. It does not retrieve the numbers saved in your contactsYes, it can send you call numbers from people who are not on it to identify them or assess whether they are spam.

Check which is your default phone app

Some Android phones come with a manufacturer's default phone app. If you open its settings, you won't find the same menus shown in a user guide. Google PhoneFirst, check which app opens when you tap the icon you use to make calls.

If you've downloaded Google Phone and want to use its features, open it and accept the request to set it as your default phone. default phone appYou can also check the default apps in your Android settings; the exact path varies depending on the brand. Google warns that not all phones are compatible with its app, so if the Play Store won't let you install it, don't force an external version.

Once configured, return to Phone > Settings > Caller ID and Spam and check the status of View caller ID and spam ID.

Why doesn't "Filter spam calls" appear either?

You might see the identifier, but not the switch. Filter spam callsGoogle explains that, on devices with Automatic call filterThat separate button is not displayed because spam blocking is managed from the filter's protection levels.

Check if your phone has a section in Settings called Call filter o Call and spam filterAvailability varies by model and country. In Spain, Google documents the manual call filtering on compatible Pixel devicesIt's not advisable to promise that all Spanish Pixel phones will have automatic filtering.

If your app offers a spam filter switch and you choose to activate it, remember that filtered calls remain in your call history, even if you don't receive the usual missed call notification. Check it occasionally if you're expecting a new number.

Don't confuse it with Pixel's "Scam Detection".

There is a third option with a similar name: Scam detectionThis feature works during the conversation and alerts you if it detects patterns of potential fraud. It is not the general spam identification setting or the pre-reply warning of a possible fake identity.

Google limits it to certain Pixel and countries. According to their current requirements, in Spain it's available for Pixel 9 and later compatible models, with exceptions like Pixel 9a and Pixel 10a, whose availability is only listed for the United States. If your phone doesn't meet these conditions, it's normal that you don't see Phone > Settings > Scam detection.

Furthermore, this feature comes disabled by default And when in use, it emits audible alerts during the call. Do not install apps or purported patches that promise to add it to an unsupported device.

What to do if you meet the requirements and don't receive alerts

Update Android and the three required apps, confirm that RCS is active, check the default app, and verify the identifier switch. Then, keep in mind that Not all suspicious calls trigger an alertThe absence of a warning does not certify that the number is authentic.

If a legitimate call is marked as spam, open the call history, select the call, and tap It's not spam.If you had blocked the number, you will also need to press UnlockAnd if the caller claims to be from your bank or another entity and asks for passwords or codes, hang up and contact them using a number obtained from their official app or website.

The diagnosis can be summarized in one distinction: Not seeing a button called "Fake Call Detection" may be normalNot even seeing the Google Phone settings forces you to review the app, its compatibility, and its configuration. None of these systems replaces independently verifying a call that requests sensitive information.
