Number blocking is temporarily removed by Samsung

How to block a subscriber

How to add to the blacklist in Viber? You can block a contact in Viber in different ways. The implementation of each of them will take literally a few seconds. Let’s step by step analyze separately the options for weeding out annoying people for users of iPhones and Android platforms.

The main reasons for blocking a user

Some people may simply not accept rejection and send messages even after being asked not to. Everyone has their own reasons for blocking, and how to implement it in several ways, we will describe in detail below.

In chat

You can ban an enemy directly from the dialog box with him:

  • Open the chat, click on “Settings” (gear located in the upper right corner of the display).
  • Scroll down the menu that opens to the item “Block this contact”.
  • We confirm our intentions by clicking “Ok”.

Block unwanted messages and calls on Samsung Galaxy S3

number, blocking, temporarily, removed, samsung

Today, are we going to try again to expand the already huge capabilities of the flagship Samsung Galaxy S3? And we will add to the standard options for an incoming call “Add to blacklist” and “Do not answer” additional options for sorting these unwanted calls and messages. New options will allow you to live peacefully without constant spam from the operator or any other annoying numbers, as well as avoid calls from unpleasant people.

In general, we need the Netqin Mobile manager application, which can greatly facilitate receiving calls and not get into unpleasant conversations. To get additional options, you just need to install this application and add unwanted contacts and numbers to the black list of Netqin application. After that, just no one will be able to get through to you, if by accident or on purpose they got into the “black list”, and spoil your mood for the whole day.

Complete setup of Netqin Mobile manager app consists of easy 8 steps.

Step In order not to search for this application in other resources or in the Google Play store, we suggest downloading it from us. Don’t forget to connect to Wi-Fi internet to save bandwidth.

Step Here, in theory, you need to describe how to install Android applications correctly, but I doubt that there are people who cannot just press a couple of buttons. Step After installing this application, launch it from the shortcut on the working window or from the list of installed applications. On the screen you will see a splash screen window describing all the features of the Netqin Mobile manager application.

Step Once you read the description of the program (we advise you to actually read it), you can go directly to the application. The Galaxy S3 will display the Program Menu, which is a dashboard with intuitive icons. So far, of all the options, we are interested in the “Blacklist” icon.

Step I think that even a school’s stock of English is enough to guess that this is a list of unwanted numbers. It can be replenished from time to time with numbers that you are tired of. Or you can add service numbers here, from which spam is constantly pouring in.

Step If before that you have experience with rather complex applications that also carried the main function of filtering incoming calls and messages, then this time we were lucky. Netqin Mobile manager is even too simple and all functions are intuitive to work with. You need to open a blacklist for numbers. There is an item “Add number”, which opens a small submenu with several options, that is, you can add an unwanted number from the phone book, message log, call log, or just enter it manually. All inscriptions are in English, however, this is unlikely to cause inconvenience.

Step If the wrong number is accidentally blacklisted, or if you suddenly want to read a blocked SMS (or view the logs of missed blocked calls), then Netqin Mobile manager has a special option that will allow you to store both SMS and phone numbers that have not passed application filter. All available information is stored in the main application menu under the Dashboard item.

Step To get a detailed report on blocked calls and SMS, go to the Netqin Mobile manager submenu named “Blocked SMS” or “Blocked Calls”. And by the way, you will not even be bothered by the mention of missed calls from unwanted people (as well as SMS notifications), although if you wish, you can enable this option in the Netqin Mobile manager settings.

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).

READ  How to properly set up the camera on Samsung

I would like to 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.

Using the service of a mobile operator

Most mobile operators have in the personal account there is a special. services to help limit “annoying” numbers. For example, Megafon has Blacklist and Super-Caller ID services.

For a small fee per month, you can activate such “things” and significantly relieve your fishing line.

This method (in my opinion) is more relevant for those devices on which you cannot install third-party applications.

For Huawei (Honor)

One of the most popular devices on our market (along with Samsung). Their software already has built-in functions for solving such a task (which is good news ).

  • first you need to open the call log (just click on the “tube” icon);
  • then select the icon with “three dots” in the top menu and go to the “Blocked” menu;
  • then go to the section “Call blocking rules”.

In this section, you can enable blocking of all unknown and hidden numbers. After that, all calls from numbers that are not in your phone book will be dropped (they will receive a line busy signal).

Thus, these calls will not distract you, and no one will occupy the line.

For Xiaomi

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

  • first you need to open “Settings” and open the “Applications” section;
  • then go to the subsection “System applications / Call settings / Antispam settings / Call blocking”. See screenshot below;
  • then activate the block from unknown and hidden numbers (example below).

Block calls from strangers (Xiaomi)

Blocking options

Pure Android (Bright Quick, Google Pixel / Nexus, LG, etc.). Black and white lists

If you do not have a device from Samsung, Xiaomi or Huawei, most likely it does not have built-in functions for blocking calls. But you can turn off all unwanted things using the “Do not disturb” function on “pure” Android (in addition, there is a way to install a special application, about it in the next section of the article).

1) first go to the “Settings” section and open the “Sounds and notifications / Alert modes” section.

Sounds and notifications. alert modes

2) After we transfer the notification mode to “Only important notifications” and indicate that only your “contacts” apply to them. How it looks is shown in the example below.

In newer versions of Android (8.0 / 9.0), this menu may look slightly different. It is necessary to open the “Sounds” section of the settings and turn on the “Do not disturb” mode (moreover, put “Contacts” among the priority calls. Example below).

3) In addition, there are black and white lists in the Android settings. Their compilation can be somewhat tedious, but nevertheless, the method is quite workable in some cases.

To use it: go to the dialing menu (just click on ✆), then you need to click on three points and go to “Settings”.

  • or “Black List”. everyone who is listed in it will not be able to get through to you;
  • or “Permitted numbers”. everyone who is not on this list will not be able to disturb you.

How to block calls from unknown and hidden numbers on Android

Good day!

Recently, there has been just some kind of epidemic of voice spam: they constantly call with an offer to take a credit card, connect to another Internet provider, some polls, and sometimes just silence in the phone.

To be honest, it’s a mystery to me why it is still not forbidden to do this (at least to all large companies), or such dealers are not blocked at the operator level. Although, “If the stars are lit, then somebody needs it.”.

In general, one of the solutions to this problem can be setting up the phone in special mode: it will drop all calls from unknown numbers. that is, those that are not in your address book (that are not entered in contacts).

All the necessary settings can be set quite quickly: everything will take about 2-3 minutes to complete. Actually, in this article I will give several ways how you can do all this.

For Samsung

I’ll start with Samsung. one of the leaders in the mobile gadgets market (if I may say so.). over, their modern smartphones (after 2019 release) already have a built-in function in their software.

How to use it: first you need to open the phone book (see example below ).

Then click on the “three points” in the corner and open the call settings.

In the section “Blocking numbers” there is a special. option to restrict unknown and hidden numbers. it must be switched to on mode.

How to make a hidden number for yourself?

Everyone who at least once saw a call on a smartphone with the inscription “Unknown”, at first fell into a stupor, and then began to look for ways to become invisible himself. The function on the Galaxy will be useful if you need to call somewhere and at the same time maintain anonymity.

Almost all Samsung models allow owners to make the call hidden through the settings. For this:

  • Go to the menu.
  • Switch to “Settings”.
  • Tap “Call settings”.
  • Click “Additional parameters”.
  • Click “Determinant”.
  • We put a tick next to “Hide number“.

After updating the parameters, the new settings will take effect, and the subscriber you are calling will see the inscription “Unknown” instead of your name or numbers. Please note that all calls will now be anonymous; to return to normal mode, you will have to dig into the settings again.

You can become hidden at a time by simply entering the combination # in front of the subscriber’s phone and all codes. This code is valid for all Android devices.

The AntiAon service is provided by all operators, but, as a rule, it is paid. There are also applications in the Playmarket, the most popular is Hide Caller ID, but it should be noted that additional programs will significantly slow down the smartphone. For the sake of a couple of anonymous calls, spending money or clogging up the device’s memory is inappropriate, especially if there are available and free methods.

Hidden Caller Blocker on Android

There are several ways how to block hidden number on Samsung phone. The function is available on most modern models, in addition, smartphone owners can download applications that allow you to manage incoming calls and block unwanted calls.

The standard method involves changing the settings in the phone itself without additional downloading any programs:

  • We go to the “Phone” menu.
  • On the page with the last calls, open the properties through the “three dots” icon.
  • Go to “Settings”.
  • We tap on “Blocking numbers”.
  • If you know the caller, enter the numbers with the operator code in the designated field. Otherwise, activate the switch “Block unknown numbers”.

Also, free applications are available for users, which can be easily downloaded from the Playmarket. One of the popular programs is Calls Blacklist, which blocks both hidden calls and calls from unknown subscribers. The only drawback of the application is that it starts automatically and constantly runs in the background, which will negatively affect the speed of the device and the rate of battery consumption.

After downloading, open the application and configure the available functionality to fit your needs:

  • In the top panel, switch to the “Black List”.
  • Activate the sliders “Calls” and “SMS”.
  • We tap on the arrow next to “Calls” and put a tick next to “Hidden numbers”.
  • We do the same with the “SMS” section.

If you do not want to receive calls from all sorts of banks with annoying applications and various offices that collect statistics, in the settings we put a tick next to the item “Unknown numbers”. Now, if a person is not in the contact list of the smartphone, he will hear long beeps, and the smartphone will not bother you with anything. The only downside is that if a loved one tries to call you from someone else’s phone, he will also be ignored, so decide for yourself whether you really need a complete lock on Android.

How to block hidden number on Samsung

How to block hidden number on Samsung if you are tired of calls from an unknown subscriber? It is quite simple to do this, and in the material we will additionally consider ways of how to become invisible yourself.

  • Select “Identifier” and uncheck the “Hide” item.

How to block SMS from the Ministry of Emergency Situations on Android

Messages from the Ministry of Emergency Situations are of a warning nature and are generally useful, because in this way a warning about possible cataclysms and emergencies is received. At the same time, many subscribers began to complain about excessive “attention” from the Ministry of Emergencies, when messages are received several times a week and are similar to synoptic forecasts.

It is impossible to block such contacts in the usual way, and mobile operators do not make concessions. To add such information to the “black list”, you can use the following hint.

How to add a number to the blacklist:

  • Select a contact from the phone book.
  • Click the “edit” sign. It is usually represented as a pencil in the upper right corner.
  • Next, you need to open the menu. It is defined differently in different versions of smartphones. Usually as three vertical dots in the upper right corner.
  • A list will appear in which you need to find the line “only voice mail” and check the confirmation box.

After such simple manipulations, an unwanted caller will not be able to bother you with calls. After dialing your number, he will hear an equally annoying offer to leave a message on his voicemail. Of course, you will not receive notifications and saved recordings from your voicemail.

If you have any questions. let us know Ask a question

How to block messages from the Ministry of Emergencies:

  • In the call log, you need to find the settings menu. To do this, select vertically located three points in the upper right corner.
  • In the proposed list, select “settings”.
  • Next, you need to find the line “block messages”.
  • From the proposed options (usually they offer blocking of numbers or message phrases), we select the last.
  • Next, it remains to select the most frequent words in messages and enter in the specified field. It is best to use specific terms here so as not to accidentally block important SMS.
  • New phrases are added by clicking on the “” icon. You can remove blocking phrases from the list in the same way by clicking on “-“.
  • Similarly, you can block annoying contacts and advertising mailings.
  • In the future, you can view incoming messages in the blocked SMS settings. You can also restore the availability of mailing, or delete messages permanently.

On Samsung

Blocking SMS on Android is very easy to explain using the example of popular Samsung phone models. To do this, there is no need to download applications or special programs, as well as generally connect to the Internet. Depending on the model of your device, two algorithms of actions can be distinguished.

When is it more appropriate to use the following function:

  • To stop contact with unwanted people.
  • To protect the child’s phone from incorrect intrusion.
  • To block potentially dangerous contacts.

It should be noted that such protection is purely conditional, because the blacklist applies only to certain, pre-specified numbers. It will be easy for your opponent to find another SIM-card, or temporarily borrow a phone from another person.

That is why, in order to radically resolve this issue, you can use the ability to block all contacts not recorded in the telephone directory. In this case, there is still a risk of missing really necessary or important information, so it is recommended to periodically check the pop with blocked messages and sort the incoming “letters” manually according to the degree of importance.

Your tablet or smartphone will delete contacts, saved records, messages, music and media content, photos, and any settings you have changed. But you can protect at least the data that is stored on flash memory. Therefore, before doing a hard reset, do not forget to remove the MicroSD.

Important information! It is recommended to do a hard reset only when the mobile device is charged at least 65%, preferably more. If you do not follow this advice, you will not be able to turn on your smartphone. It will not necessarily happen, but there is such a danger.

Example of Factory Reset on Samsung Phones

Since we cannot simply enter the phone menu when locked, we will need to reset it with a combination of buttons. This combination is different for each mobile phone or tablet model. To find out it, go to the official website of the manufacturer or find information on the Internet.

Samsung phones also use different keyboard shortcuts. But the general instructions for resetting the settings to the original, factory parameters are as follows:

The only difference is in the key combination used to load device recovery mode. Again, the information can be found on the official websites of the manufacturers.

So, you have learned how to remove the unlock pattern from an android if it is impossible to use the standard operating system tools. Yes, the method is tough, but in some cases the only possible, and most importantly safe.

Discharging the device

In this case, we need to wait for the battery to discharge. When the battery charge reaches a certain minimum, a warning will be triggered. You need to enter the battery status menu and from there go to “Settings”, where you can turn off the graphic password.

Using a Google account

To unlock your mobile device, follow these instructions exactly:

  • Make several attempts (usually five is enough) to enter the pattern. Since the figure is drawn incorrectly by you, the gadget will be blocked. In this case, a notification will appear on the screen about the opportunity to repeat attempts after a while (usually 30-60 seconds).
  • As a rule, after incorrectly entering the pattern, the HOME button appears on the screen. If your mobile device doesn’t have it, try a few more password attempts. You can use this method only if you have an active Internet connection. Otherwise, use other options.
  • The essence of the solution lies in the fact that you can remove a forgotten pattern from an Android device using a personal Google account. By pressing the “Home” button, you get the opportunity to log into your account and change the “picture”. For authorization, use your personal password and e-mail address. After specifying the identification data, click “OK”. If the information you entered is correct, authorization will occur. The system will offer to “draw” a new key.
