How to Find Blacklist in HTC Desire 820 S Dual Sim

The blacklist is one of the most important functions of a smartphone. It allows you to block spammers and unwanted calls. There may come a moment when the user would need to remove one or more contacts from the block list. In this case, it is important to know where the blacklist is located on the HTC Desire 820 S Dual Sim phone.

How the Blacklist Works

To understand where the blacklist is located, you first need to understand how the feature works. After all, you can block a number by a variety of means. Here are some basic blocking options:

• via the standard Phone application;
• via a special app;
• by activating the service with your telecom operator;
• in a messenger.

Thus, each specified blocking method provides its own blacklist. Meaning that you can block a number via the regular phone app, but that person will still be able to call you in a messenger.

Ways to View the Blacklist

Now let’s look at how to view the blacklist on the HTC Desire 820 S Dual Sim phone depending on the method of blocking a number. To do this, let’s consider the main options for adding numbers to the blacklist.

Regular Phone App

Like any other smartphone with Android OS on board, HTC Desire 820 S Dual Sim has a built-in Phone application. The app has its own blacklist that automatically blocks calls from unwanted numbers. To view the blocked numbers, you need:

1. Open the standard application for making calls.
2. Go to settings by clicking on the icon with three dots.
3. Select "Block numbers".
4. Read the list and, if necessary, unblock the required number.

This setting also allows you to block people from the contact list. If the number was stored in the phone book, the person's name will be displayed next to it.

Personal Account with a Telecom Operator

The function of blocking unwanted numbers is available with almost all mobile operators as a paid service. In fact, it duplicates the capabilities of a standard dialer, but you won’t be able to get a list of blocked contacts through the Phone application. Generally, the block list is displayed in the proprietary application of the operator and in the client's personal account. Interaction with the numbers is also carried out here.

A Special App

With the help of the Play Market, a specialized app can be installed on the HTC Desire 820 S Dual Sim smartphone, which can be used to block unwanted callers. If you are using the Call Blacklist application, do the following to get acquainted with the blacklist:

1. Run the application.
2. Go to the Blacklist section.
3. See the list of blocked numbers.

As with a standard dialer app, Call Blacklist and other similar applications allow you to interact with callers in every possible way by blocking calls or SMS messages separately. It also provides the ability to add and exclude numbers from the blacklist.

Blacklist in a Messenger

As it was mentioned above, a person blocked through a standard dialer can contact the owner of HTC Desire 820 S Dual Sim using a messenger. This forces the user to block the number not only in the Phone application, but also in WhatsApp or Telegram, depending on which application is used for correspondence.

Let's look at a blacklist in a messenger using WhatsApp as an example:

1. Run the application.
2. Press the button with three dots.
3. Open up Settings.
4. Go to the Account section, and then to Privacy.
   
5. At the bottom of the page, open the Blocked tab.
6. Browse through the blocked numbers.

The list of blocked contacts can be checked via Telegram, Viber and other instant messengers in a similar fashion. However, the names of some of the menu items can differ.
