    How to block numbers and messages on a Samsung smartphone using the program

    If you also want to manage your list of blocked calls, then try the free Blacklist app. It allows you to replenish the blacklist with a saved contact, number from the journal, or simply add it manually.

    By blocking, the phone stops informing you about an incoming call or message, but their history is stored in the application itself, so you will always know about an attempt to call or write to you.

    The main advantages of the Blacklist program:

    • Blocking all unknown numbers (which are not in contacts)
    • Blocking numbers that start with a specific digit
    • Notifications about numbers you have added to the blacklist
    • Export of the list of blocked numbers
    • Block all SMS
    • Blocking private, that is, hidden numbers.

    The application is very lightweight and doesn’t require a lot of resources to work in the background. If you use programs to speed up the smartphone system, then you need to add this tool to the exceptions, since they can conflict.

    How to block calls from unknown and hidden numbers on Android

    Good day!

    Lately, it’s 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.

    Honestly, it is a mystery to me why they still do not prohibit doing this (at least for all large companies), or block such dealers 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 a 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.

    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 and you will not be distracted, and no one will occupy the line.

    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 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, it should be noted that there are 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.

    How to remove the screen lock on Android if you forgot your password or is prohibited by the administrator

    In order to protect personal information, the screen of any Android smartphone can be locked. And this is done in different ways. This is necessary, for example, when you have lost your device. But sometimes there is absolutely no need for such protection and it only takes time when the device is turned on. In this article, we will tell you what kind of screen locks are on Android. We will also find out how to remove them or, on the contrary, install them.

    Samsung and TouchWiz

    This add-on or shell from the Korean manufacturer visually differs from the unmodified Android. Therefore, at work with her, it is also worth focusing attention. To remove protection here, do the following:

    • As in the case of Xiaomi, we lower the “curtain” and press the settings button.
    • Scroll down the contents of the window and tap on the item marked on the screen.
    • We see the item “Blocking type” and immediately observe the type of installed protection. In order to change it or remove it altogether, click on the line circled in red.
    • To confirm, enter the pattern.
    • Select the item “Swipe across the screen”. this is the disabling of the security check.
    • Here we will be warned that the previously saved data will be deleted (meaning the pattern itself). We confirm our intentions by tapping on the “DELETE” button.

    After that, the password will be reset and the phone’s power-on protection is canceled.

    An example is shown based on the Samsung Galaxy Grand Prime, but it is also suitable for other smartphones of this brand.

    What to do if prohibited by the administrator

    Sometimes a person knows his PIN-code, pattern or password, but still it is impossible to remove it. In order to solve this problem as well, we do this:

    • Go to the applications menu. In this case, this is Android 6, but in other versions of the OS, the sequence of actions is similar.
    samsung, lock
    • Next, we need the item “Device Administrators”.
    • Let’s see what applications are on this list. For example, remote shutdown and locking can affect the prohibition of changing the password. You may have other functions here, you can also disable them for testing. Click on the checkmark indicated in the screenshot.
    • Below is a list of powers. There is also a screen lock, perhaps it is she who interferes with us. Click “DISABLE”.

    In each specific case, the set of applications in the administration center may be different. Act according to your particular situation.

    Xiaomi and MIUI

    Let’s also consider disabling protection on a proprietary shell from the Chinese manufacturer Xiaomi, namely MIUI. In our case, this is its 9th version.

    • Move the notification bar down with a swipe and tap on the settings launch icon. It looks like a gear.
    • Since our phone supports fingerprint, we select the advisory section. We marked it in the screenshot.
    • Then we go directly to the lock itself.
    • We will need to enter the password that was set earlier. If this is not done, the settings cannot be changed. Therefore, we register the code and press the enter button.
    • Click on the line with the inscription “Disable blocking”.
    • The system will notify us that if we continue, the lock will be removed and we will no longer be able to use the fingerprint. If this does not scare you, then click “OK”.

    That’s all with Xiaomi, but not everything with a lock. Let’s consider how to remove it in Samsung’s notorious TouchWiz.

    Android 2.x

    We will review the OS editions from Google in the order of their appearance. Let’s skip only the very old Android 1.x and purely tablet 3.x.

    • To remove protection in Google Android 2.x, you must first go to the applications menu. Its icon is indicated in the screenshot below.
    • Next, we are interested in the settings. Tap on the gear icon or something similar.
    • At the next stage, click on “Location and protection”.
    • We pass to the item with the name “Change the blocking method”.
    • Since we had an active PIN-code, it will be necessary to enter a cipher to disable it. If you have other protection, for example, a pattern or password, respectively, specify them. What to do if you do not know this data is written at the very end of the article.
    • So, when verification is done, you can disable protection. To do this, we simply click on the item marked in the screenshot.

    Also below you can see the rest of the blocking methods supported on the second Android.

    We rise higher and pass to the consideration of the 4th version of OS.

    For security reasons, it is usually necessary to enter the current code, password or pattern to unlock the phone. if, of course, they are already installed.
