A smartphone should be a means of communication with loved ones and business partners, and not a source of constant irritation due to spam or annoying calls. Device owners Samsung Galaxy A50 often face a situation where you need to quickly limit a certain subscriber’s access to your personal space. Fortunately, the shell One UIinstalled on this device provides powerful and flexible tools for managing incoming calls without the need to install third-party software.
The locking procedure on this device is intuitive, but has its own nuances depending on the firmware version and the type of SIM card. We will look at all available methods: from instant blocking through the call log to creating complex ban lists. You'll learn how to use your provider's built-in caller ID and how to set up automatic screening of unknown callers so that your phone only rings when it's really needed.
Before you get started with the settings, it's worth noting that different methods are suitable for different scenarios. If you need to block one specific person, a quick method through call history will do. If you suffer from massive spam, you will need deeper filter settings. Let's look at each option in as much detail as possible so that you can choose the best solution for your situation.
Quick blocking via call log
The fastest way to stop calls from a specific person is to use call history. This action takes only a few seconds and does not require a deep dive into the system settings. Open the standard application Phone, which is usually located at the bottom of the screen on the quick access panel.
Find the number you want to block in the list of recent calls. Note that the contact's name may appear next to the number if it is saved in your address book. Click on that number or name to reveal more information about the call. In the menu that opens, you will see a button Block or a ban icon.
After clicking, the system may request confirmation of the action. This is done to protect against accidental blocking of important contacts. Confirm your intention and the number will be immediately blacklisted. Now the subscriber will not be able to reach you, and his messages will not be displayed in the standard messages application.
⚠️ Attention: When blocking through the call log, you can accidentally block a number that differs from the desired one by just one digit. Always carefully check the sequence of numbers before confirming the action, especially if the number is not saved in your contacts.
If you blocked a number by mistake, you can just as quickly unblock it by going to the blocking settings and deleting the entry from the list of blocked contacts.
Blocking through the contacts menu and address book
If the number is already saved in your phone book, the blocking process becomes even more clear. Open the application Contact or go to the contacts tab inside the application Phone. Find the person you need alphabetically or use the search bar at the top of the screen.
Open the contact card. At the top of the screen, next to your name and photo (if you have one), you will see three vertical dots. This is the additional actions menu. Click on it and select Blockfrom the drop-down list. The system will immediately apply restrictions to this contact.
An alternative method is to use the button More, which can be located at the bottom of the contact card screen. The logic of action remains the same: select the blocking function and confirm. It's important to understand that blocking a contact does not remove it from your memory. You will still be able to see his number and correspondence history, but he will not be able to initiate communication with you.
- 📞 Blocking through a contact works even if the subscriber changes the name in his address book, since the binding goes to the number.
- 📝 The blocked contact is marked with a special icon so that you do not forget about the restriction status.
- 🔄 You can unblock the subscriber at any time by simply repeating the procedure and selecting the unblock option.
Setting up global filters and black list
To fine-tune the rules for processing incoming calls, you need to go to the main application settings menu Phone. Click on the three dots in the upper right corner of the main dialing screen and select Settings. In the list that opens, find the section Blocking numbers.
Here you find yourself in the control center for your digital peace of mind. The interface may vary slightly depending on the version One UI, but the basic functions remain unchanged. You will see a list of already blocked numbers, which you can edit manually. The button Add number allows you to blacklist any phone, even if it has not called you before.
Switches for automatic filters are available in the same menu. For example, the function Block unknown numbers rejects calls from those who have hidden their caller ID. This is an extremely useful option for fighting fraudsters, but it should be used with caution so as not to miss an important call from a courier or doctor using a corporate PBX with a hidden number.
Settings → Blocking numbers → Add number⚠️ Attention: The function of blocking unknown numbers may not be available or work incorrectly if your mobile operator does not transmit correct caller information or uses specific voice protocols.
☑️ Checking the black list settings
Using the Smart Call function and anti-spam protection
Smartphones Samsung equipped with an advanced system Smart Callthat works in partnership with a database of spam numbers. This feature not only blocks calls, but also identifies potentially dangerous or advertising numbers before you even pick up the phone. A warning may appear on the call screen indicating that the caller is a spammer or scammer.
To activate this protection, go to Settings applications Phone and find Caller ID and anti-spam protection. Activate the switch. Now the smartphone will check incoming numbers with the online database and mark suspicious calls in red or with the words “Probably spam.”
You can configure the level of filtering aggression. In the anti-spam menu, there is often an option to automatically block numbers marked as "High Risk". This allows you to completely get rid of most advertising calls without your participation. The database is updated regularly, so the protection remains up to date.
| Filtering type | Description of action | Recommendation |
|---|---|---|
| Blocking hidden | Rejects calls without identification numbers | Enable only in case of strong spam |
| Smart Call | Warns about known spammers | Recommended to keep enabled |
| Automatic spam | Drops calls from the database scammers | Ideal for complete silence |
| Manual list | Blocking specific contacts | For resolving personal conflicts |
What happens to the call when blocked?
When a blocked subscriber calls you, he hears beeps or a message that the subscriber is unavailable, depending on the operator settings. On your screen, the phone may blink or not respond at all, and the call immediately goes to the missed log with a blocking mark.
Blocking messages and multimedia content
It is important to understand that blocking a number in the application Phone does not always automatically apply to the application Messages. In some firmware versions, these settings are synchronized, but to fully guarantee digital hygiene, it is better to check the messenger settings separately. Open the messages application and go to its settings through the menu.
Find the section Blocking and filtering. Here you can add numbers to the blacklist specifically for SMS and MMS. This is relevant if you are not harassed by calls, but by advertising mailings or offensive messages. The mechanism of operation is similar to the telephone one: adding a number to the list of prohibited ones.
On Samsung devices with One UI 3.0 shell and higher, blocking is often the same for calls and messages, but older versions of the software may require separate settings. Check for messages from a blocked contact in the "Spam and blocked" folder, which is located in the messages menu. All rejected messages go there.
- 💬 Blocked messages are not deleted, but are moved to a special folder for scanning.
- 🚫 You can set up automatic cleaning of the spam folder after a certain time.
- 📩 The message filter can work by keywords, and not just by sender numbers.
⚠️ Attention: Blocking a number does not guarantee 100% protection from all types of messages, especially if spam mailing is carried out through Internet messengers (WhatsApp, Telegram, Viber). For them, you need to set up blocking within the applications themselves.
Comprehensive protection requires setting up blocking both in the Phone application and in the Messages application, as well as inside third-party instant messengers.
Solving common problems and questions
Sometimes users are faced with a situation where the setting does not work as expected. The number can still be called, or the blocking is reset after a reboot. Most often this is due to the fact that the number is stored in two different places: in the phone memory and on the SIM card. Make sure that you are blocking exactly the contact that is currently active.
It is also worth considering the peculiarities of mobile operators. Some "Anti-spam" services from the operator may conflict with the built-in functions of the smartphone. If you use an operator's paid call filtering service, try disabling it or, conversely, using only it to avoid duplication of functions and glitches in operation Samsung A50.
If the list of blocked numbers is full, the system may start to work slower or ignore new additions. Periodically clear the black list of numbers that are no longer relevant. This will help maintain the performance of the call processing system at a high level.
Periodically check the "Spam and blocked" folder in your messages. Sometimes important confirmation codes from banks or notifications from delivery services get there by mistake.
Will the blocked subscriber see that I blocked him?
The subscriber will not receive a direct notification about the blocking. However, he can guess this from indirect signs: the call will be dropped after one ring or immediately, and messages will not have the “Delivered” status.
Is it possible to block the entire range of numbers or only specific ones?
Using standard Android and One UI tools, you can block only specific numbers or categories (hidden, unknown). Blocking by number mask (for example, all numbers starting with +7999) requires the installation of third-party applications from Google Play.
What to do if the "Block" button is inactive?
This can happen if the number is a service or emergency number. Also check if you have any third-party calling apps installed that could intercept control. Try using the standard Samsung application.
Is call history from a blocked contact saved?
Yes, information about dialing attempts is saved in the call log. You will see the missed call with a note that it was automatically rejected or blocked, depending on the display settings.
How to unblock a number if I forgot which one it was?
Go to the number blocking settings. A complete list of all contacts included in the black lijst is displayed there. You can view it, find the one you need and click on the trash can icon or the cross next to the number to unblock.
