A constant stream of advertising notifications and messages from scammers turns using a smartphone into real stress. Device owners Samsung Galaxy often encounter intrusive mailings that not only take up memory, but may also contain malicious links. Fortunately, the ecosystem Android and the proprietary One UI shell provide powerful tools for filtering incoming traffic.
In this material we will analyze in detail all the available methods: from built-in functions to installing specialized software. You will learn how to create black lists, set up automatic filters by keywords and block entire groups of numbers. This will help you regain control over your device and personal space.
Using the built-in spam filter in the Messages application
Modern versions of the One UI shell installed on smartphones Samsungalready have a pre-installed protection mechanism against unwanted content. This feature works at the system level and does not require the installation of third-party apps. To activate protection, you need to go to the settings of the messaging application itself.
Open the application Messages and click on the three vertical dots in the upper right corner of the screen. In the drop-down menu, select Settings, and then go to the Spam and fraud protectionsection. Here you will see a switch that needs to be switched to the active position. Once turned on, the system will begin to automatically analyze incoming texts.
The function uses a database of known fraudulent numbers and machine learning algorithms to identify suspicious patterns. If a message is recognized as spam, it will not appear in the general list of chats, but will be moved to a special folder Spam and Blocked. You can check this folder at any time to make sure that important notifications from banks or delivery services do not end up there.
Check the Spam and Blocked folder periodically, as automatic filters can sometimes misclassify legitimate messages from new contacts.
It is worth noting that that the effectiveness of the built-in filter may vary depending on the region and telecom operator. Algorithms are constantly updated, but for maximum protection it is recommended to combine this method with manual blocking of specific subscribers.
Manual blocking of specific numbers through the call log
Sometimes automatic systems miss annoying advertisers who use new numbers. In such cases, manual blocking is the most effective solution. This method ensures that a specific subscriber will no longer be able to call or send you an SMS message. The blocking procedure is simplified as much as possible in the interface. You don't need to look for complex menus; all actions are performed in a few touches directly from the call log or correspondence list. This is an ideal option for dealing with personal harassment or annoying couriers. SMS message.
The blocking procedure is simplified as much as possible in the interface Samsung. You don't need to look for complex menus; all actions are performed in a few touches directly from the call log or correspondence list. This is ideal for dealing with personal harassment or annoying couriers.

- ⚙️ Select the option
BlockorBlock numberin the action menu (often indicated by a ban icon). - ✅ Confirm the action in the pop-up window.
After completing these steps, all communication attempts from this number will be interrupted at the device level. The subscriber will receive a standard busy tone or unavailable message, while you will not receive any notifications.
☑️ Checking the number blocking
Setting up a black list and managing blocked contacts
The list of unwanted contacts is managed through a single phone settings center. Here you can not only add new numbers, but also view your blocking history, and, if necessary, unblock someone by accident. This is especially true if you changed your decision or the number was transferred to a new owner.
To access the full list, go to Settings smartphone, then select section Applications. Find Messages or Phone in the list (depending on what you want to configure) and open their settings. In the blocking menu you will see the item Blocked numbers. By clicking on it, you will be taken to the access control table.
In this section the following options are available:
- ➕ Manually adding a number through the button
Add number. - 🗑️ Removing a number from the black list by clicking on the trash can or cross icon.
- 📋 Importing a list of contacts from the phone book for mass blocking.
The management interface allows you to quickly edit the list. If you blocked a number by mistake, it will only take a couple of seconds to restore it. Here you can also see the date and time of the last communication attempt from a blocked subscriber, which helps track the activity of scammers.
| Action | Location in the menu | Result |
|---|---|---|
| Blocking unknowns | Settings → Messages → Spam protection | Hiding messages from numbers outside the contact book |
| Manual blocking | Call log → Details → Block | Complete ban on communication with a specific number |
| Filter by words | Settings → Messages → Filter by keywords | Sifting messages with certain vocabulary |
| View log | Settings → Blocked numbers | Viewing the history of rejected calls and SMS |
⚠️ Attention! Blocking a number does not delete messages already received from it. You will have to manually delete them from the Spam and Blocked folder if you want to completely clear your chat history.
Blocking messages from unknown numbers and hidden contacts
One of the most annoying problems is messages from numbers that are not saved in your phone book. These can be either random erroneous sendings or targeted attacks by scammers. In the settings Samsung there is a function that allows you to automatically hide such messages.
To activate this mode, go to the application settings Messages and find the item Protection against spam and fraud. Within this section there is often an option Block messages from unknown numbers or similar wording. When you enable this feature, all SMS from contacts that are not in your list will be automatically redirected to the spam folder.
This method is extremely effective for users who do not expect important messages from strangers. However, be careful: if you are waiting for a confirmation code from a new service, courier or doctor, the message may not arrive in your main inbox. In this case, you will need to temporarily disable the filter or check your spam folder.
What happens to messages from hidden numbers?
The system marks them as spam and hides the notification. The text of the message is saved in the archive, but sound and vibration do not work. You can restore a message to the main mailbox if it was mistakenly filtered.
Using this setting significantly reduces information noise. Most advertising mailings are carried out from new or temporary numbers that do not have time to get into global spammer databases, but are easily cut off by this local filter.
Filtering SMS by keywords and phrases
Advanced users have access to a filtering tool based on text content. This allows you to block messages even if they come from different numbers but contain the same advertising slogans or names of suspicious services. The function works as an intelligent barrier to unwanted content.
To configure, go to the menu Protection against spam and fraud in message settings. Select an item Keyword filter. Here you can create your own list of phrases, the presence of which in the text of a message will lead to its automatic blocking. The system will scan each incoming SMS for matches.
It is recommended to add to the list the following common terms often used by scammers and spammers:
- 🎁"Win","Prize","Lottery"
- 💰"Credit","Loan","Payday Money"
- 🔗 Domain abbreviations of popular phishing sites
- 📢 Names dubious bookmakers
After adding a keyword, all messages containing this phrase will be instantly moved to an isolated folder. This is a powerful tool, but it must be used wisely so as not to block legitimate notifications that may accidentally contain these words in another context.
Keyword filtering is a proactive defense that even works against new numbers that have not yet been added to spam databases.
⚠️ Attention! Don't add too general words to the filter (for example, "code" or "bank"), otherwise you may miss important notifications from financial institutions or authentication services.
Third-party applications for maximum anti-spam protection
If the built-in tools Samsung are not enough for you, the market offers many specialized applications that use global databases to identify spam. The leaders in this niche are solutions from Truecaller, Mr. Number i Kaspersky. They are able to identify not only known spam numbers, but also flag suspicious calls in real time.
Installing such an application gives access to large communities of users who jointly flag scammers. When you receive a call or text from a number that has already been flagged as "Scam" or "Advertising" by thousands of other people, the app will alert you before you open the message. This creates the effect of herd immunity.
However, the use of third-party software has its own nuances. Such applications often require broad permissions to access your contacts and call logs in order to function correctly. Before installation, carefully review the developer's privacy policy. In addition, some features may only be available in the paid version.
To install, go to Google Play Market, enter the application name in the search and click Install. Once launched, follow the setup wizard, granting the necessary permissions. Typically, the application automatically integrates into the system and begins filtering incoming traffic in parallel with built-in tools.
⚠️ Attention! Application interfaces and menu names may vary slightly depending on the version of Android and your Samsung device model. If you do not find this option, use the search inside the settings menu.
Frequently asked questions (FAQ)
Will the sender see that I have blocked their number?
No, the sender will not receive any special notification about the blocking. For him, the message will look like it was sent successfully. However, he will not receive a delivery report if this feature is enabled, which may indirectly hint at blocking.
Is it possible to recover messages from the "Spam and blocked" folder?
Yes, it is possible. Go to the folder Spam and blocked in the Messages application, long press the desired message, then select the option Recover or move it to the main inbox manually.
Does the blacklist block calls or just SMS?
When blocking a number through the standard menu Samsung usually both calls and SMS messages are blocked simultaneously. This is comprehensive protection from a specific subscriber.
What to do if scammers change numbers and continue to send spam?
In this case, the solution would be to enable filtering "from unknown numbers" or use a third-party application with a cloud database that automatically updates lists of scammers.
Does blocking affect numbers per battery charge?
Built-in filters consume a minimum amount of resources. Third-party applications may consume a little more energy due to constant background checking of databases, but on modern models Samsung Galaxy this impact is almost invisible.
