Daily calls from spammers, annoying advertising agents and scammers have become a real scourge for smartphone owners. This problem is especially acute for device users Samsung Galaxywho often become targets due to the popularity of the brand in the market. Extraneous calls not only distract you from important matters, but can also lead to financial losses if you accidentally answer a scammer.

Fortunately, the shell One UIinstalled on smartphones of the South Korean company offers powerful built-in tools for filtering incoming calls. You don't have to install third-party apps, which often require questionable permissions and overload the system. It is enough to correctly configure standard phone functions to forget about telephone terrorism forever.

In this article we will analyze in detail all available protection methods: from activating the built-in caller ID to creating strict blocking rules. You will learn how to set up automatic call rejection and use the capabilities of your telecom operator to create a reliable barrier between you and unwanted callers.

Built-in Smart Call protection and caller ID

The first and most effective line of defense is the function Smart Call. Developed by Hiya in partnership with Samsung, this service allows you to identify incoming calls in real time. The system checks the number against a global database of spam numbers and flags the call as “Spam”, “Fraud” or “Advertising” even before you pick up the phone.

To activate this feature, you need to go to the application Phone, click on the three dots in the upper right corner and select Settings. Next, find the item Caller ID and anti-spam protection. Make sure the switch is activated. If the system prompts you to accept the terms of use and privacy policy, agree to them for the full operation of the service.

After turning on Smart Call you will be able to not only see the tags suspicious numbers, but also automatically block them. In the same settings, find the item Anti-spam protection and enable the option Block spam and fraudulent calls. Now the phone will automatically reject calls from the database blacklist without even bothering you with a beep.

⚠️ Attention: The Smart Call function requires access to the Internet (mobile or Wi-Fi) for the database to work in real time. If you are in an area without network coverage, identifying unknown numbers may not work.

It is important to note that the database is constantly updated, but no system gives a 100% guarantee. Sometimes regular numbers from banks or delivery services can be mistakenly marked as spam, so it is worth checking your blocked call log periodically.

Periodically check your blocked call log in the Phone app to make sure you haven't missed an important call from a courier or doctor that the system has mistakenly identified as spam.

Manual blocking and blacklist management

If automatic filters miss specific annoying subscribers, the most reliable way is to manually add the number to Blacklist. This method allows you to block a specific person or organization forever, regardless of whether they change their calling tactics.

There are several ways to add a contact to the block list on Samsung. The fastest way is to open the call log, find the intruder’s number and click on it. In the menu that appears, select the option Block number. Confirm the action, and this subscriber will no longer be able to reach you.

For more detailed settings, go to Settings applications Phone and select item Blocking numbers. Here you will see a list of all blocked contacts. You can add numbers manually by entering them from the keyboard, or block entire categories, for example, "Unknown numbers" (hidden numbers) or "All other numbers" (except those in your phone book).

  • 🚫 Blocking hidden numbers: Activate the "Block unknown/hidden numbers" switch to block calls from those who hide their ID.
  • 📞 Blocking by mask: Some versions of One UI allow you to block numbers starting with certain numbers (for example, all numbers of a specific operator).
  • 📝 Import the list: You can load a list of spammers from a file or copy it from another device for mass blocking.

When a blocked subscriber tries to call you, he hears short beeps or a message that the subscriber is unavailable, while your phone is silent. A record of such a call can be saved in a separate log of blocked calls, but will not be displayed in the main feed of missed calls.

Do not disturb mode as a radical measure

In situations where the flow of calls becomes uncontrollable, or you need absolute silence for work and rest, the mode comes to the rescue Do not disturb (Do Not Disturb). This is not just a silent mode, but a powerful filter that can completely ignore incoming calls from all but selected contacts.

You can activate the mode through the notification curtain by clicking on the corresponding icon, or through the settings Sounds and vibration. However, the real power of this tool is revealed in its parameters. Go to the mode settings and find the section Calls and messages. Here you can choose who has the right to interrupt your peace of mind.

It is recommended to set the permission for calls only from Favorites or Contacts. In this case, any number that is not in your phone book will be automatically rejected by the phone. This is an ideal option for combating mass spam, when unknown numbers pour in like a cornucopia.

Permission parameter Who can call Effectiveness against spam
No one Calls are prohibited for everyone 100% (absolute silence)
Only selected ones Only contacts with an asterisk 99% (only your own will get through)
All contacts Any number from the phone book 90% (spam from unknown people is blocked)
All Any numbers 0% (the mode only mutes the sound)

You can also set up a schedule for the Do Not Disturb mode. For example, set it to turn on automatically from 22:00 to 08:00 or during business hours. This will save you from having to manually enable protection each time.

What will a caller see in Do Not Disturb mode?

A subscriber who has fallen under the Do Not Disturb mode filter will hear standard call tones, and then hang up. There will be no special notification on its screen that you have enabled this mode; for it you simply “don’t pick up the phone.”

Using the services of mobile operators

In addition to the settings of the smartphone itself, mobile operators provide significant assistance in the fight against spam. Each major provider in Russia and the CIS has its own anti-spam services that work at the network level, even before the signal reaches yours. Services such as Antispam from MTS, Antispam from Beeline or Call Intercept from MegaFon analyze traffic and block calls from numbers blacklisted by the operator. Often these services are paid, but their cost is symbolic compared to the nerves saved. Samsung Galaxy.

Services such as Antispam from MTS, Antispam from Beeline or Call Intercept from MegaFon analyze traffic and block calls from numbers blacklisted by the operator. Often these services are paid, but their cost is symbolic compared to the nerves saved.

To activate the service, it is usually enough to send a USSD command or activate the option in the operator’s personal account. The advantage of a network blocker is that it does not drain your phone's battery and does not require the installation of additional applications. Blocking occurs “in the cloud.”

⚠️ Attention: The terms and conditions for the provision of anti-spam services, their cost and functionality may be changed by telecom operators without prior notice. Always check the latest information about tariffs and connection commands in the official application of your operator or on the website.

Some operators offer the “White List” function, when only those numbers that you have specifically included in the allowed list can be reached. This is the most rigid filter that completely cuts off the entire outside world, except for close people.

💡

Combining Samsung's built-in protection and operator services gives a double effect: the operator cuts off massive robospam at the network level, and the phone filters the remaining suspicious calls locally.

Third-party applications for filtering calls

If standard tools are not enough for you, the market offers many specialized applications to combat unwanted calls calls. The leaders in this niche are Yandex.Caller Identifier, Kaspersky Who Calls i Call Blocker. These apps have huge databases generated by the users themselves.

The principle of operation of such applications is that when there is an incoming call, the app checks the number with its database. If a number is flagged by thousands of users as “Taxi”, “Food Delivery” or “Scammers”, the application will show this information on the screen or automatically drop the call.

However, using third-party software has its own nuances. First, such apps require access to your contacts and call logs, which raises questions about data privacy. Secondly, they can consume more energy than Samsung’s built-in solutions.

  • 🛡️ Yandex.Identifier: Knows the numbers of Russian delivery services, taxis and government agencies very well.
  • 🔒 Kaspersky Who Calls: Emphasizes security and identifying fraudulent schemes, rather than just advertising calls.
  • ⚙️ Call Blocker: Offers flexible blocking rules, for example, by area code or the first digit of the number.

When installing such an application, the Android system will ask for permission to use it as a caller ID assistant. You will need to go to the call settings and select the installed application instead of the standard Samsung ID so that it can intercept calls.

Prevention: how to avoid becoming a victim of spammers

The best protection is prevention. We often hand over our numbers to spammers' databases by registering on dubious sites, participating in online surveys, or leaving our contacts publicly available. Digital hygiene will help reduce unwanted calls in the long run.

Try not to list your main phone number on message boards or social media. For such purposes, it is better to get a second SIM card or use a virtual number. If the call comes from an unknown number and you are not expecting an important call, it is better not to call back.

Calling back to a spam number confirms to scammers that your number is active and is owned by a real person. After this, the intensity of calls can increase significantly. Also, you should not press buttons in robot voice menus, for example, “press 1 to unsubscribe.” This is often a trick to mark you as a compliant victim.

⚠️ Attention: Never give SMS codes, bank card details or passport details over the phone, even if the caller claims to be a bank or police officer. Real employees never ask for such information during an incoming call.

Regularly check where your number is used. There are services that allow you to see data leaks, but the best way is to be careful when filling out questionnaires and registration forms on the Internet.

Frequently asked questions (FAQ)

Will the blocked subscriber know that I have blacklisted him?

No, directly he won't know about it. When a call is made, he will hear the usual beeps and then the call will be dropped. There will be no special blocking notification on his phone. However, if he rings many times and always hears a reset after the first ring, he may guess that he is blocked.

Is it possible to block calls only at certain times of the day without Do Not Disturb mode?

You cannot set up a schedule for the blacklist using the standard means of the Phone application on Samsung. For this purpose, it is best to use the Do Not Disturb mode, setting a schedule and allowing calls only from contacts. Third-party applications may also offer this feature.

What should you do if an important number (for example, from a doctor) is in the spam database and is blocked?

You need to go to the blocked call log in the Phone application, find this number and remove it from the blacklist. You can also add this number to your contacts and assign it the “Favorites” category so that it passes through any filters.

Does blocking numbers affect the operation of SMS from these subscribers?

Usually adding a number to the blacklist in the Phone application only blocks voice calls. SMS messages from this number may continue to arrive. To block messages, you need to use the settings of the Messages application or the anti-spam functions in the messages section.

Are blocking settings reset when updating the Android system?

No, your blacklist and caller ID settings are stored in the device’s memory and linked to your account or local database. When you update the firmware or One UI system, these settings are saved, and you do not have to configure them again.
