The Spam and sales calls have become a real nightmare For anyone with a smartphone, aggressive offers, unclear promotions, or outright scam attempts disrupt daily life with unknown numbers that keep calling. If you're looking for how End spam and commercial callsThere are several combined strategies that work well.
Fortunately, Google has been incorporating a very powerful system into Android and, above all, into the Pixel. Google Phone app all with automatically detect, filter and block these types of callsWe're talking about the combination of caller ID, spam protection, and the Call Screen call filterwhich you can configure so that your mobile phone does almost all the work for you.
What is Google's caller ID and spam protection?
Google's caller ID and spam protection is a built-in feature of the Google Phone app that analyzes incoming and outgoing calls to show who's calling and warn you if the number is suspected of being spam. It also allows options for block calls specific ones from the history.
When you have it activated, the system can display on screen the name of a company or service that is calling you, even if it's not on your agenda, or warnings like "Suspected spam" or "Spam" so you know it's probably an unwanted call.
To provide this protection, your phone needs send Google basic information about the callsIf you call or receive a call from a number that isn't in your contacts, that number is compared against the company's databases and detection systems to determine if it might be spam or which company it belongs to. Google spam protection combines multiple sources to identify risks.
It is important to be clear that Google does not download or obtain the numbers from your contact listOnly unknown numbers involved in the calls are processed, and the company applies its privacy and data protection policies to this processing.
This system mixes lists of reported numbers, detection algorithms, and artificial intelligence which are constantly updated and allow you to distinguish between legitimate business calls, fraud attempts, robocalls, and normal communications. It's also advisable to review methods that actually work when you want to actively reduce discomfort.
How to turn caller ID and spam protection on or off
On most phones that use the Google Phone app, these features come pre-installed. factory activatedBut you can review and adjust it in seconds. The switch only affects spam detection and smart caller ID; it doesn't control whether your number is displayed or hidden when you call.
To manage it from the Google Phone app on Android, the general steps are very simple: open the application, enter the menu of settings related to “Caller ID and spam” and enable or disable the options you want. You'll usually see something like "View caller ID and spam ID" and another checkbox for “Filter spam calls”.
If you enable filtering, the system can automatically block or silence calls detected as spamIn that case, those calls don't usually ring the phone or generate normal missed call notifications, although they are recorded in the call history and, if applicable, in the voicemail box.
On devices that already have the Automatic call filter (Call Screen)This "Filter spam calls" option may not appear because automatic blocking is integrated as one of the protection levels of Call Screen itself.
On newer Pixel phones, such as the Pixel 6 and later, basic spam filtering is considered part of the standard protection level of the call filterIn previous models, this is equivalent to settings such as "Reject calls silently" within the spam calls section.
How Pixel Call Screen and call filtering work with Google Assistant
Pixel Call Screen is an evolution of conventional filtering that It's only available on Google Pixel phones. (and in a very limited way in some markets). Here we are no longer just talking about identifying spam, but about allowing it Google Assistant answers for you to the calls to find out who is calling and with what intention.
The idea is very simple but incredibly effective: when you receive a call from a private or unknown number, instead of answering or hanging up, a button will appear on the call screen. “Filter call”If you touch it, it's not you who answers, but the Google Assistant.
At that moment, the caller hears an automated message informing them that they are speaking to Google's call filter and is then instructed to... He asks her to state her name and the reason for the call.Meanwhile, on your mobile phone you see a real time transcription to what the other person is answering.
From that screen you can decide if you want Answer yourself, hang up, mark the number as spam, or let the assistant continue.Additionally, you have suggested quick responses so the assistant can ask further questions, clarify if the call is urgent, or ask you to repeat the information if it wasn't clear.
The interesting thing is that, as the months have passed, many users have found that Sales calls are drastically reducedCompanies that make mass calls often find that an automated filter always answers, requiring identification, and in many cases They choose to stop insisting in those numbers.
Where is Google's call filter available?
Google's call filter as such (Call Screen with answering assistant) is primarily intended for Google PixelHowever, there are several layers of availability depending on the country and the type of filtering.
First, the full automatic filteringThe feature, in which the assistant can answer and manage calls without your initial intervention, is available in the United States for all compatible Pixel phones. It's the most advanced level, with different levels of protection (basic, medium, and maximum).
Furthermore, there is the manual filteringwhere you choose to filter a specific call by pressing the "Filter call" button. This option is available on Pixel phones in several countries, such as Spain, Australia, Canada, France, Germany, Ireland, Italy, Japan, the United Kingdom and the United States.
On some non-Pixel Android devices in Canada and the United States, manual call filtering can also be used when the Google Phone app and the carrier allow it, but the full experience is usually reserved for Pixel devices.
It should be remembered that the Manual filtering only works with SIM cards from countries where the feature is officially supported.If you use a SIM card from another country, the call filter settings may not appear in the Phone app.
Configure automatic call filtering on your Pixel phone
Before activating automatic filtering, certain requirements must be met. Firstly, Call filter is not compatible with third-party apps that record the screen or callsTherefore, it is advisable to disable or uninstall those types of applications to avoid conflicts.
On the other hand, you must make sure that You have the latest version of the Google Phone app from the Play Store. If you see the "Update" button, do so before continuing with the setup.
Once a day, the basic adjustment is to enter the Phone app and, from the options menu, look for the section “Call and spam filter” or “Call filter”Within this menu you will have access to the Call Screen settings.
In the Call Filter section you can choose the protection levelOptions such as maximum, medium, or basic protection are usually available. Each one manages differently which types of calls are automatically filtered and which ones come through directly.
in models Pixel 6 and earlierYou will often see a subsection like "Unknown Calls Settings", where you can decide what types of numbers (e.g., potential spam, numbers not in contacts, private calls, etc.) you want to filter.
in models Pixel 7 and laterThe system organizes these options around the “Level of protection”with a switch to “Automatically filter calls” and lists to choose how to handle them spam, potential fake numbers, and first-time callsThis way you adapt the filtering to your risk tolerance.
Pixel Watch and call filter: how to take advantage of Call Screen on your wrist
If you have a Pixel WatchYou can also benefit from the call filter, although with conditions. Currently, the automatic filter for the watch is only available in United States and requires at least a paired Pixel 6 or later model.
In addition, you need to have the Google Phone app on your mobile and watch Updated to recent versions (around 116 or higher on the phone and 50 or higher on the watch, according to Google documentation). Both apps can be updated from Google Play.
The key to making it work is that the Pixel Watch is connected via Bluetooth to your Pixel phoneIn that scenario, when you receive a call, the automatic and manual filtering options will be coordinated between your mobile phone and watch so you can view the transcript or manage the call without taking your phone out of your pocket.
How to automatically filter calls with Call Screen
With automatic filtering enabled, your Pixel can intercept certain types of calls on its own. When this happens, you'll see a silent notification like this: “Filtering unknown number” or “Filtering suspicious call”, instead of the phone ringing normally.
If you tap that notification while the assistant is on the call, you'll access a real-time transcription of the conversation between the caller and Call Center. This way you can read what's happening without having to speak.
During this process, the assistant asks standard questions to find out who is calling and for what purposeBased on the responses and its detection systems, the mobile phone makes a decision: if it determines that it is spam, it hangs up automatically; if it seems like a legitimate call, it lets the phone ring and shows you what the other person replied.
Keep in mind that while the leak is occurring, the device may be affected. pause music or video playbackThis is normal behavior, as the call takes priority over the multimedia content.
There are some important limitations: if you are using Bluetooth headphones or the phone is connected to another device via BluetoothDepending on the model, automatic filtering may not be activated. Furthermore, It doesn't work when you're roamingAnd if you use call forwarding, it's not recommended to activate automatic filtering, as filtered calls are not forwarded correctly.
Filter calls manually from the call screen
Without having to leave everything in the hands of the system, you will always have the option to Manually filter out any incoming callsWhen the phone rings and you see the call screen, the "Filter call" button will appear next to the usual answer and hang-up buttons.
If you choose to filter, Call Support will handle the answering for you and ask who is calling and whyFrom there, a transcription of the interlocutor's responses is generated on the fly.
Once the other person has answered, you decide the next step: You can choose a suggested response, answer the call yourself, or hang up.The caller will hear a message tailored to the option you select.
Common suggested responses include messages such as “Is it urgent?”, to clarify if the call is a priority, options for Mark the number as spam and ask them to stop calling, or phrases like "I'll call you later" so that the assistant informs that you cannot answer now but will return the call later.
You can also use a message to indicate that You haven't understood what was said correctly, and I'd like you to repeat the information.All this without you having to speak directly, since the assistant plays the answer while you just read the transcript and press the button that suits you best.
AI responses on Call Screen: more natural and flexible
Google is taking call filtering a step further with the addition of responses generated by artificial intelligence on Call Screen. These responses are created directly on the device based on what the caller is saying.
Unlike predefined answers, these AI-powered options are more contextual and natural, adapting better to the specific situation of the call, whether to clarify doubts, ask for more details or end the conversation politely.
References to internal names such as “dobby_AI“or “dobby_LLM”, which point precisely to the use of language models to generate these new intelligent responses based on what is being transcribed.
Even so, Google warns that the The generated responses may not be perfect. These tools do not represent our official position; they are simply an additional resource to help you manage calls more efficiently. By using them, you agree to the terms of service applicable to the use of AI in these products.
What to do if you can't find the option to filter calls
On some phones you might enter the Phone app and I don't see any clear "Call Filter" sectionIn these cases, it's advisable to follow some basic steps to confirm if your device is compatible or if any configuration is missing.
Open the Phone app and go to Settings. There you should find a section called “Call and spam filter” or simply “Call filter”If it appears, tap it and follow any on-screen instructions to activate the feature.
If no guide is displayed or No filter-related settings appearThat feature is most likely not available for your phone model, your region, or the specific version of the Phone app you're using.
In the case of many non-Pixel Android devices, you can continue using the part of Google's standard caller ID and antispam or resort to the solutions offered by the manufacturer itself, such as Samsung's spam filter or similar tools in layers like MIUI.
Transcripts and recordings of the leaked calls
One of the key advantages of Call Screen is that All filtered calls generate a transcript. which is saved on your phone, so you can check it later even if you didn't answer the call in real time.
In the call filter settings, you can enable the option (if your model allows it) to Also save the filter audioThis way, in addition to the text, you'll have a recording of how the interaction with the assistant unfolded.
To view these transcripts, simply open the Phone app, go to the main "Home" or History tab, and tap the filtered call you want to reviewThe call details will include options such as "Transcription" or "Transcription and audio".
If you don't see those buttons immediately, there's usually a "History" or "View Transcript" section within the call details. From there, you can read the full transcript and, when available, play the audio generated by the call filter.
If at any point you want to delete that information, simply Press and hold the filtered call and tap deleteThis deletes both the transcript and the recording associated with that specific call from the device's storage.
How it's decided which calls are filtered: behavior and limits
The call filter primarily uses the contacts you have saved on your phone to decide whether a call should be filtered or not. As a general rule, if you don't want a number to go through the filter, saving it as a contact is a good idea.
However, no system is infallible: Not all automated or spam calls are always detectedSome attempts may slip through if they use new numbers or techniques that are not yet included in Google's databases and algorithms.
Filtered calls are not stored in your Google account Nor are they displayed in sections such as Call Support Activity or Web and App Activity. The information is stored locally on the phone, except for the minimum data necessary to improve spam detection overall.
In addition to the roaming and call forwarding problems we've already discussed, it's worth assuming that The transcription system will not always understand perfectly What the caller says: accents, background noise, or a bad connection can cause occasional errors in the text.
Therefore, although Google's spam filter is very effective, it is still advisable to use common sense and not provide sensitive personal data to any suspicious number, although it apparently has not been marked as spam.
Marking calls and numbers as spam or as "not spam"
In addition to automatic filtering, you can also do it yourself. manually report nuisance callsThis not only stops you from receiving them from that number, but also helps Google's global system detect new spam sources more quickly.
If you want to mark a number as spam, open the Phone app, go to the recent calls section and Tap the call you want to blockYou will usually see a "Block/Mark as spam" option to indicate that it is unwanted.
On many mobile phones, that's all you need to do. press and hold the call in the list Then select the block and report option. From that moment on, calls from that number will be blocked, and Google will consider it a potential spam sender for other users.
If, however, the system has marked a legitimate call as spam (for example, from an acquaintance or a company you want to deal with), you can Report the errorIn the list of recent calls, tap the call in question and select "Not spam".
By doing this, Future calls from that number will no longer be shown as spam.And you can unblock the number if you had previously blocked it. It's a way to train the protection system to better suit your actual contacts.
Verify and suggest caller IDs for businesses
Another feature added to the Google Phone app is the ability to Verify or share information about companies that call you.This way, you help other users see on their screen the name and category of the company behind that number.
This information may appear in incoming calls and give clear clues as to why that number is calling you: it could be a bank, an educational center, an NGO, a technical service or a specific marketing campaign.
If you want to collaborate, open the Phone app, go to the Home or History tab and Tap on options like “Was it a business?” or “Caller ID comments”Next, follow the instructions to verify or suggest the name and type of business.
Once you have completed the form, click “Submit”. If you indicated that the number does not belong to a company, That information will not be sent to GoogleEverything you send is processed without including your personal data, focusing solely on identifying the number.
If you later want to change your mind about a number, you can do so on the home tab. Press and hold the call and select “Send feedback” again to update what you had said.
Manufacturer phone apps: alternatives and add-ons
The Google Phone app comes pre-installed not only on Pixel phones, but also on many phones from brands like Xiaomi or MotorolaAnd in all of them you can take advantage of basic anti-spam protection and, in some cases, advanced filtering.
If your phone doesn't come with it as standard, you can download it for free from Google Play and use it as your main phone app. When you set it up, you can enable the "View caller ID and spam" and "Filter spam calls" options, which greatly reduces the number of annoying calls.
In the app settings you also have the section for “Blocked numbers”Ideal for managing numbers you want to completely block. From there you can manually block specific phone numbers or, if you prefer, block any calls from unsaved numbers.
However, if you decide to block all calls from unknown numbers, keep in mind that You could miss important communications from courier companies, doctors, public services, or people you haven't yet added to your address book.
Aside from Google, many manufacturers integrate their own anti-spam solution. For example, Samsung Galaxy offers a "Caller ID and Anti-spam" option in its native phone app, powered by Hiya's database. From there, you can activate detection and decide whether to block only high-risk calls or everything that looks like spam.
Other methods to reduce spam: laws, lists, and additional blocking
In countries like Spain, the reform of the General Telecommunications Law It has tightened the rules for marketing calls. Companies need prior consent and must respect users' preferences regarding advertising contact.
Even so, unwanted calls still come in, so it's advisable to combine Google's technology with other measures. One of the best-known is... sign up to advertising exclusion lists, such as the Robinson List, which tells companies that you do not want to receive offers by phone.
It's also useful to continue blocking manually. the numbers that are repeated insistently From your phone app, you can also use "Do Not Disturb" mode during certain times so that only calls from your contacts or favorites can ring.
Devices with interfaces like MIUI include dialer apps that They automatically mark in red the calls detected as commercial.making them easy to identify at a glance. On iPhone, you can activate spam filters and unwanted call detection using Apple's tools in Settings > Security.
When faced with suspicious fraudulent calls, the basic recommendation remains to not give out personal or banking information. not even if the call seems legitimateIf in doubt, hang up and contact the entity yourself through official channels before providing any information.
By combining Google's caller ID and filtering features with manual blocking, spam reporting, and available legal tools, it's possible to achieve Let the phone become a useful tool again and not a constant source of annoyance, letting Call Screen and the rest of the systems do most of the dirty work for you.
