Constant calls from spammers, collectors or scammers from unknown numbers can irritate even the calmest smartphone owner. For device users Samsung this problem is especially acute, given the popularity of the brand and, as a result, the frequency of leaks of customer databases. Fortunately, the ecosystem Android and the proprietary shell One UI provide powerful tools for filtering unwanted calls without the need to install third-party software.
In this guide, we will take a closer look at the standard blocking functions built directly into the Samsung phone application, as well as look at more advanced protection methods. You will learn how to set up automatic rejection of calls from subscribers who hide their number, and what settings of telecom operators can help in the fight against telephone terrorism.
The problem cannot be ignored, since every missed call from a scammer is a risk of losing money or personal data. Modern spam detection algorithms work quite effectively, but require correct initial configuration on the part of the user. Let's move on to specific steps that will help you regain peace and tranquility.
Using Samsung's built-in anti-spam protection
The company has integrated a feature into its devices Samsung has integrated the function into its devices Smart Callthat works in partnership with the Hiya database. This system automatically identifies suspicious numbers and marks them as spam before you even pick up the phone. To activate this protection, you need to go to the phone application settings.
Open the application Phone and click on the three dots in the upper right corner of the screen. In the drop-down menu, select Settings, and then find the section Number identification and spam blocking. Move the slider to the active position. Now the system will check incoming calls against the global database of fraudulent numbers.
For maximum efficiency, it is also recommended to enable the automatic blocking function. In the same menu, find the option Block spam and suspicious numbers. Activating this option ensures that calls from numbers marked by the community as dangerous will be automatically rejected, and your phone will not even ring.
⚠️ Attention: The Smart Call feature requires an Internet connection to update the databases. If you are roaming or in an area of poor coverage, the effectiveness of spam detection may be reduced.
The menu interface may vary slightly depending on the version One UI and model of your smartphone. If you do not find the specified item, check the section
Security and privacyin the general settings of the device.
Turn on displaying the spam call category in the Smart Call settings to see the “Advertising” or “Fraud” mark on the screen before answering the call.
Blocking calls from hidden and unknown numbers
A separate category of annoying calls comes from subscribers who deliberately hide their number (defined as "Unknown number" or "Private number"). Standard blocking lists based on specific numbers will not help here, since the number is different each time or is missing altogether. There is a special function in Samsung settings to solve this problem.
Go to Settings applications Phone and select Block numbers. Here you will see a switch Block unknown/hidden numbers. Activate it. Once enabled, all calls where the subscriber ID is not transmitted to the network will be automatically rejected.
Keep in mind, that this setting is quite radical. It can cut off not only spammers, but also important calls from doctors, couriers or government employees who sometimes use secure communication lines. Use this function only if the flow of hidden calls has become unbearable.
- 📞 Calls from hidden numbers are often used by debt collectors to put pressure on the debtor.
- 🕵️♂️ Fraudsters hide the number to avoid feedback and blocking by the victim.
- 🏥 Some government services and banks use gateways with a hidden number for outgoing calls.
Blocking hidden numbers is a “nuclear button”. Use it only in extreme cases when other filtering methods fail.
Manual management of the contact blacklist
If automatic filters miss specific annoying callers, you can always add them to the blacklist manually. This is a reliable way to get rid of being harassed by a specific number. Managing the Blocked numbers list is located in the same call settings menu.
To add a number, click on the icon + or select Add number. You can enter the number manually or select it from your call and contact history. After adding this subscriber will no longer be able to reach you; it will hear beeps or a busy message, depending on the operator's settings.
It is also convenient to block numbers directly from the call log. Click on a specific number in the list of recent calls, then select the Block/Send spamicon. The system will offer not only to block a contact, but also to send a spam report to the database, helping to protect other users.
| Action | Where to find | Result |
|---|---|---|
| Blocking a specific numbers | Call log → Block | The subscriber cannot get through |
| Blocking hidden numbers | Settings → Block numbers | All calls without ID |
| Spam complaint | Settings → Smart Call | The number is included in the Hiya database |
| Removal from the black list | Settings → Block numbers | Resuming communication with a subscriber |
Third-party applications for enhanced protection
Samsung's built-in tools are often sufficient, but if you encounter aggressive spam, specialized applications from Google Play can offer more in-depth analysis. The market leaders are Truecaller, Kaspersky Who Calls and Yandex.Caller ID.
These applications use their own, often more extensive databases than standard solutions. They can identify not only known scammers, but also annoying marketers, delivery services and courier services that have not yet been included in global blacklists. Installing such an application requires granting permissions to access the call log and contacts.
After installation, the application is integrated into the Android calling system. When you receive an incoming call, the caller's name will be displayed on the screen, even if it is not in your phone book, as well as the category (for example, "Taxi" or "Food Delivery"). You can set up automatic blocking for certain categories of numbers.
Impact on battery
Third-party caller IDs work in the background and may slightly increase battery consumption as they constantly monitor incoming calls and check them against online databases.
⚠️ Attention: When installing third-party caller ID, carefully read the privacy policy. Some services can upload your phone book to their servers to replenish the database.
Mobile operator services for blocking spam
Do not forget that large mobile operators (the "Big Four" in the Russian Federation and analogues in other countries) offer their own anti-spam services. These solutions work at the network level, that is, the call is blocked even before it reaches your smartphone Samsung.
For example, MTS has an Antispam service, Beeline has an Antispam service, and MegaFon has a similar service. The connection is usually made through the operator’s personal application or USSD command. The advantage of this method is that it does not consume the processor and memory resources of your phone.
Often such services are provided free of charge or for a nominal fee as part of the tariff. They are especially effective against robocallers, since the operator can analyze call patterns and block mass mailings at the switch level.
- 📡 Blocking occurs on the operator’s side, saving smartphone battery power.
- ⚙️ Does not require installing additional applications or setting up the phone.
- 💰 Some advanced features (for example, SMS messages about blocked calls) may be paid.
☑️ Checking the operator's protection
Do Not Disturb mode as a radical measure
In situations where none of the above methods helps, or you need absolute silence for a short period, you can use the Do not disturb (Do Not Disturb) mode. This mode allows you to configure your phone so that it receives calls only from selected contacts.
Activate the mode through the notification shade or in settings Sounds and vibration. In the mode parameters, find the section Calls and messages and select the option Favorites only or Contacts only. All calls from numbers that are not in your address book will be muted.
This ideal for weekends or nighttime, when the likelihood of an important call from a stranger tends to zero, and the risk of disturbing sleep is high. Don't forget to turn off the mode when it's no longer relevant so you don't miss really important calls.
How to quickly add a contact to your favorites for Do Not Disturb mode?
Open the Contacts application, find the person you want and tap on the star icon. Or go to the Do Not Disturb settings, select Favorite Contacts and manually add the numbers you need there. Such calls will go through even in the strictest silence mode.
Is it possible to block spam calls if the number changes every time?
Yes, for this it is best to use a combination of the built-in Smart Call function and telecom operator services. They analyze not only the number, but also behavioral factors (call frequency, complaints from other users), which allows them to block entire pools of numbers used by spammers.
Will the caller see that he is blocked on Samsung?
As a rule, the blocked subscriber hears regular beeps, which are then interrupted, or immediately goes to voicemail. It does not receive a special message about blocking, which allows you to maintain your anonymity and avoid conflicts.
Does blocking a number affect the ability to send me SMS?
In standard Samsung settings, call blocking does not always block SMS messages from the same number. To stop text spam, you need to add a number to the blacklist in the application Messages or use comprehensive solutions from operators.
