How to block unknown numbers on Samsung

Highly dangerous calls

Also, I think everyone has heard about this kind of fraud as the “investigator’s call” when they tell you “your son made an accident where a person died. If you want to resolve the issue. transfer money “

I tell all this to the fact that calls from unfamiliar numbers are often distracting, annoying, and sometimes lead to extremely unpleasant consequences. If you are a modern sane person, you can easily distinguish a normal call from a “divorce”. However, children or elderly family members who have personal mobile phones are best protected from such contacts. Even if it is better for calls from subscribers who are not in contacts, their devices simply “silently drop” the call.

If there are no such settings in the phone (Samsung Galaxy, bare Android)

If you have a Samsung Galaxy or Google Pixel / Nexus, then you don’t have the same out-of-the-box feature as Xiaomi or Huawei. Therefore, you have two options:

  • Use a third party call manager. However, here it should be remembered that high-quality applications are often paid.
  • Use do not disturb mode built into Android. In this case, the phone will be able, if not to block (drop) such calls, then at least not to give a call signal and not distract you about an incomprehensible call from an unfamiliar number.

Block voice calls in messengers on Android

The first thing to say about voice calls in messengers on Android. this is that they are not affected in any way by the presence of a number in the blacklist, nor by the activated blocking mode of all subscribers who are not included in contacts.

Those. if you have blocked some number on the phone (in the dialer), then this does not mean at all that the same person will not be able to call you by voice communication via WhatsApp, Viber or any other application.

The most popular applications in Russia. Votsape and Viber. do not have the ability to block calls from people who are not included in the contact list. Here you can only block a single number, i.e. ban a specific user.

If strangers call you on Whatsapp or Viber, then in Android you will have to block every unfamiliar number in every application.

To block an unfamiliar number in WhatsApp on Android, we do this:

  • Go to the “Calls” tab;
  • select the subscriber you want to ban.
    You need to touch the left side of the entry where the name or phone number is displayed, but not on the handset!
  • tap on the “menu” icon (three dots);
  • select “Block”;
  • on the next screen, confirm your intentions by clicking “Block” again:

And here’s how to block individual users in the Viber Android app:

  • go to the “Calls” section;
  • select the user from whom you do not want to receive Viber calls;
  • click three dots in the corner of the screen;
  • click “Block”:

block, unknown, numbers, samsung

You can also click on the missed call and in the Chats section and select Block. Do it the way it is easier for you.


  • Open Settings scroll to the Applications section select System applications Call settings Antispam Call blocking.
  • Activate 2 functions: Block calls from strangers and Block calls from hidden numbers:

Now you can only get through to those people whose numbers are entered in Contacts. The rest of the calls will be blocked.

Confusion in function names

And once again we want to emphasize what we wrote about at the beginning of the article: in phones with the Android operating system, there is a confusion in the names of functions. The fact is that both in the Russian interface language and when switching the smartphone to English, the names “Blocking unknown subscribers”, “Unknown numbers” or “Unknown” are misleading (which is translated into Russian in exactly the same way).

The user may think that when the function of barring calls from “Unknown” numbers is turned on, the phone will block calls from people who are not recorded in the phone and are not known to you personally. However, in reality, this option means something else. blocking calls from subscribers with a hidden number (when instead of 7 (123) 4567890 it says “Unknown”, “Number is hidden”, “Unknown” or “Private number” on the screen). There is a separate instruction about this, the link to which we gave at the very beginning of this article.

Universal version (using special applications)

If using the built-in functions (presented above) you did not manage to solve the problem, you can resort to special. applications. Their arsenal of functions is much richer than simple blocking. I will give a couple of them below.

Block SMS and calls from unknown numbers

The “Blacklist” application is designed to quickly and easily block any unwanted calls and SMS (both from unknown numbers and your created lists).

I note that calls are blocked quietly and without any notifications on the phone screen (i.e. you can not be distracted and calmly work at the device at this time).

Also, one cannot fail to note the presence of filters that allow you to block all calls from numbers starting with certain numbers (sometimes this is also necessary).

Do not call me. call blocker

Blocking all suspicious numbers

This application is distinguished primarily by the fact that in its arsenal there is a database of “bad” numbers (including it is formed by other users when they rate (however, you can do this too)). Thanks to this kind of “social protection”, all bad numbers very quickly get into the stop list, and you are protected from them.

With regard to locks, an application can:

  • block all unknown and hidden calls;
  • block outgoing calls to paid and foreign numbers;
  • block work with numbers that have a low rating from other users;
  • use and operate on your own blacklists.

Important: the application does not block numbers on your contact list.

For Xiaomi

Another very famous Chinese brand. Their software also has a similar option, however, it is set somewhat differently:
