In the modern digital world, instant messengers have become an integral part of our lives, but along with convenience they also bring unwanted attention. Spam, intrusive advertising, or simply communicating with people that you want to stop are common reasons for searching for a solution. Users of the operating system Android often wonder how to effectively limit access to their data or completely block unwanted contacts in a popular application Viber.
The blocking process can imply two completely different scenarios: protecting your own device from strangers or blacklisting a specific subscriber within the application. In the first case, we are talking about the security of the smartphone itself, in the second, about digital etiquette and personal space. Understanding the differences between these procedures is critical to properly setting up your gadget.
In this article we will analyze in detail all the available access restriction methods. You will learn how to set up a password code for logging into the messenger itself, how to add an annoying interlocutor to your ignore list, and what hidden privacy features the developer offers. We will also look at the nuances of how these functions work on different versions of the operating system.
Setting a password and fingerprint to enter the application
The first level of protection, which is available to every owner of a smartphone based on Android, is setting an additional barrier when entering the messenger itself. This function does not completely block the phone, but makes it impossible for anyone who picks up your unlocked device to read correspondence and view calls. Activation Viber Passcode is a basic security measure.
To enable this function, you must go to the settings of the application itself. The interface may differ slightly depending on the firmware version of your device, but the logic remains the same. You will need to find the section responsible for privacy and activate the requirement to enter a code every time you start the app.
Modern smartphones have biometric sensors that greatly simplify the authorization process. Instead of entering numbers, you can use your fingerprint or facial recognition technology if supported by your device. This not only speeds up access, but also increases the level of security, since biometric data is more difficult to fake than a simple PIN code.
⚠️ Attention: Do not use simple combinations like 1234 or 0000 as a password. Attackers often check these obvious options first when attempting unauthorized access.
Remember that if you forget the set password code, restoring access to correspondence within the application may become impossible without a complete reinstallation Viberwhich will lead to the loss of the history of messages not saved in the backup copy. Therefore, write down complex combinations in a safe place.

How to add a contact to the blacklist inside Viber
The most common situation requiring user intervention is the need to stop communicating with a specific person. The messenger Viber implements the “Black List” function, which allows you to completely isolate an unwanted subscriber. After adding a number to this list, the user will not be able to call you or send a message through the app.
The procedure for blocking a specific contact is performed directly from the interlocutor’s card. This is an intuitive process that takes a few seconds. Just open a dialog or user profile, find the menu of additional options and select the appropriate action. The system will immediately stop delivering any notifications from this number.
It is important to understand the technical side of this process: the blocked subscriber still sees your “online” status and profile photo if you have not hidden them in your privacy settings. However, his messages will not be delivered and calls will be dropped automatically without ringing for him. For you, his activity will become completely invisible.
- 📱 Open the application and go to the “Calls” or “Chats” tab.
- 👤 Find the contact you want to block and click on his name.
- ⚙️ Click on the three dots in the upper corner of the screen to open menu.
- 🚫 Select “Block” and confirm the action.
It is also possible to block directly from the list of recent calls. If you receive a spam call, you can click on the number in the call log, go to the contact information and immediately send it to the ignore list. This is especially useful for fighting phone scammers.
If the number is not saved in your phone book, you can still block it. Just open a chat with this number or find it in the call log inside the application.
Managing a list of blocked numbers
Sometimes users lose control over who exactly they blocked, especially if this function has been used for a long time or in a state of passion. It Viber provides a convenient interface for viewing and managing the entire list of ignored contacts. This allows you to quickly check whether someone got there by mistake.
To access this list, you must return to your privacy settings. There you will find a separate item displaying the number of blocked numbers. By clicking on it, you will see a complete list of subscribers who cannot contact you. From here you can easily restore communication by simply deleting the contact from the list.
Managing this list is especially important when life circumstances change. For example, after resolving a conflict with a colleague or relative, you will want to remove the block. The system allows you to do this in one click, after which the user will again be able to write and call you as if nothing had happened.
| Action | Where to find | Result |
|---|---|---|
| View list | Settings → Confidentiality → Blacklist | Displaying all blocked numbers |
| Unblocking | Clicking on the cross next to the name | The contact can write and call again |
| Blocking unknown | From chat or call log | Instant spammer isolation |
| Clearing history | Deleting a chat after blocking | Complete removal of traces of communication |
Please note that deleting a contact from the phone book of your Androidsmartphone does not automatically unlock it in the messenger. If you've added a number to your blacklist inside the app, it will remain there even if you erase it from your phone's contacts. Deletion must be done manually through the interface Viber.
Hiding status and photos from strangers
Blocking a specific number is a radical measure, but sometimes more fine-tuning of privacy is required. You can remain available for communication, but hide your activity from a wide range of people. In the settings Viber on Android you can flexibly configure who sees the time of your last visit, online status and profile photo.
The function of hiding the “Online” status works in one-way mode. If you hide your status from everyone, you won't be able to see other users' status either. This is an important limitation that you should be aware of before changing settings. You will only see those who have not hidden their status from you, but you yourself will become “invisible” to everyone.
Setting the visibility of your profile photo also plays an important role in protecting against unwanted attention. You can make sure that only contacts from your address book see your photo. This effectively protects against the creation of fake profiles with your photo by unknown people who found your number in open sources.
⚠️ Attention: Changes in privacy settings may not take effect immediately. If the other person has already loaded your photo into his phone's cache, he can still see it for some time even after you have hidden it in the settings.
To configure these settings, go to the Privacysection. There you will find the items “Online Status” and “Profile Photo”. Select the “Nobody” or “My Contacts” option, depending on how strictly you want to limit the visibility of your information.
What a blocked user sees
Many users are concerned about the anonymity of the blocking procedure. I would like to know if the blocked person will receive any notification that he has been blacklisted. The developers Viber tried to make this process as invisible as possible for both parties in order to avoid unnecessary conflicts.
A blocked subscriber does not receive any system notifications, push messages or letters indicating that he is blocked. For him, the situation looks like your phone is simply turned off, there is no Internet, or you are ignoring messages. However, there are indirect signs by which an attentive user can guess about blocking.
The main indicator is the message delivery status. If messages remain in the "sent" status (one check mark) for a long time, and previously they were delivered instantly, this is a wake-up call. Also, the lack of updating the “was online” time for weeks may indicate that you have hidden the status or blocked the person.
Technical details of message delivery
When blocked, the Viber server receives a message from the sender, but does not forward it to the recipient’s device. That is why the sender has one tick. The server does not inform the sender about the reason for the non-delivery, simulating technical problems on the recipient's side.
Calls also do not go through. The blocked user will hear a beep or immediately be reset, depending on the version of the application and the telecom operator, but no special signal “the subscriber has blocked you” will follow. This allows you to maintain diplomacy in difficult social situations.
Alternative methods of protection and archiving chats
In addition to direct blocking, there are less radical ways to protect yourself from information noise. For example, the chat archiving feature allows you to remove the dialogue out of sight without completely interrupting the connection. This is useful if you want to take a break from communication, but are not ready to completely break the contact.
An archived chat disappears from the main list of conversations and is moved to a special “Archive” folder. You will not receive pop-up notifications for new messages from this chat until you access the archive yourself. However, if a blocked user writes to you, the message will not arrive, and in the case of an archive, it will simply quietly wait for you to read it.
Another method is to turn off notifications for a specific contact. You can keep a person in your contacts list, but prevent the phone from alerting you with sound or light about their calls and messages. This is done through the settings of a specific chat: Information → Notifications → Off.
- 📂 Archiving hides the chat, but does not block incoming ones.
- 🔇 Disabling notifications leaves the chat visible, but makes it “silent.”
- 🚫 Complete blocking prevents any communication through the app.
Using a combination of these methods allows you to build layered defense of your personal space. You can archive work chats for the weekend, mute notifications from noisy groups and block outright spammers, using different tools for different tasks.
Combine privacy tools: use archive for a temporary pause, mute for intrusive acquaintances and blacklist for aggressive spammers.
