In the era of digital communications, telephone calls have become not only a means of communication, but also a source of constant irritation due to intrusive marketing and fraudulent schemes. Users of Androiddevices are increasingly looking for effective ways to protect themselves from unwanted communication, and one of the most popular solutions is the application Kaspersky Who Calls. This tool, developed by a well-known antivirus development company, allows you not only to identify the caller, but also to block spam before you even pick up the phone.
Many smartphone owners are wondering where to find the official version of the app in order to download it for free and not fear for the security of their personal data. Unlike dubious caller IDs, which often trade on the user's contact database, Kaspersky guarantees a high level of confidentiality. In this article, we will go through in detail the process of installing, configuring and using all the functions of the application to ensure your peace of mind.
It is important to note that the basic version of the functionality is available to every user without the need for a paid subscription, which makes this product accessible to a wide audience. We will look at exactly what opportunities open up to you after installation, and how to properly set up filters to let through only really important calls from loved ones, colleagues or delivery services.
Key features of Kaspersky Caller ID
The application Who Calls is a powerful tool that integrates into your device’s phone book and works in the background. The main task of the app is to instantly identify an incoming call using a huge database of numbers, which is constantly updated by the users and company analysts themselves. If you receive a call from a bank, a taxi service, or, conversely, annoying advertisers, you will see it on the lock screen even before you answer.
One of the key features is the ability to not only see the name of the caller, but also categorize incoming connections. The system automatically tags the numbers with tags such as “Spam”, “Telemarketing”, “Finance” or “Delivery”. This allows the user Android to instantly make a decision: answer the call or ignore it, saving time and nerves.
- 🛡️ Spam blocking: Automatic shutdown of calls from numbers marked as fraudulent or advertising.
- 📞 Caller ID: Display the name of the organization or service type even if the contact is not saved in your book.
- 🔒 Confidentiality: All data is processed in compliance with strict security protocols specific to the products Kaspersky.
It is worth emphasizing that the application does not work in isolation, but in conjunction with system functions your smartphone. It requests the necessary permissions to control calls, which is standard for any quality caller. Without granting these rights, the app will not be able to intercept the incoming signal and display information on the screen.
⚠️ Attention: For the detector to work correctly, you must grant the application permission to access the contact list and call log. Without this, the identification function will not work, since the app will have nothing to check the incoming number with.
Where to download Kaspersky Who Calls for free and safely
The first and most important step is to obtain the installation file from a trusted source. For owners of devices based Android there are several boot paths, but security should come first. Downloading APK files from dubious sites can lead to infection of the device with malicious code that is disguised as a useful utility.
The official and most secure distribution channel is the store Google Play. This is where the current version of the application is located, which has passed all security checks. In the search bar of the store, just enter the query “Kaspersky Who Calls” or “Kaspersky Who Calls” to find the desired product from the developer Kaspersky Lab.
In some cases, for example, on devices without Google services or in certain regions, the application may not be available directly through the Play Market. In such a situation, you can use the official website of the developer or proven application catalogs, such as APKPure or Galaxy Store for Samsung devices. However, always check the digital signature of the developer before installation.
Before installing an application from a third-party source, be sure to enable file scanning in your antivirus, even if it is a product from the same manufacturer.
The installation process is standard for the operating system Android. After downloading the file, you must confirm the installation by allowing the browser or file manager to install applications from unknown sources if you do not use Google Play. The system will issue a security warning that you must accept in order to continue.
Step-by-step guide for installation and initial setup
After successfully downloading the application to your device, you must carry out the correct initial setup. This stage determines how effectively the protection against unwanted calls will work. Do not ignore the permission requests that will appear immediately after the first launch.
First, open the installed application. You will see a welcome screen asking you to enable basic features. Click the "Start" or "Activate" button. The system will redirect you to the call management menu of your smartphone, where you will need to select Kaspersky Who Calls as the default application for working with calls and SMS (if applicable).
☑️ Settings checklist
Next you will need to allow access to the contact book. This is necessary so that the application can check incoming numbers with your personal database and not mark familiar numbers as spam, as well as to download current databases from the server. The system pop-up window Android will require your confirmation.
An important step is to configure the display. Make sure that "Display on top of other apps" is enabled in your phone settings. This will allow a card with the caller's name and a spam warning to appear on top of the lock screen or running games and videos without interrupting their work.
| Settings parameter | Recommended value | Impact on operation |
|---|---|---|
| Access to contacts | Allowed | Necessary for the number database to work |
| Display on top of windows | Enabled | Display caller card on locked screen |
| Autostart | Allowed | Guarantees protection after reboot |
| Notifications | Enabled | Notification about blocked calls |
After completing all steps, the application will ask you to restart the device or simply complete the setup. It is recommended to immediately check the operation by asking someone you know to call you to make sure that the detector is working correctly.
How to set up blocking of unwanted calls
The main value of the application lies in its ability to filter incoming traffic. In the settings menu Who Calls you will find the “Blocking” or “Filters” section. Here you can flexibly configure which categories of numbers should be automatically rejected.
You can enable blocking of all numbers with a hidden identifier, which is often used by scammers. The "Silent Mode" function is also available, when calls from certain categories (for example, telemarketing) will not make sound or vibration, but will simply be dropped or sent to voicemail, if supported by the operator.
- 🚫 Black list: Ability to manually add specific numbers that you want to block forever.
- ✅ White list: Section for numbers, calls from which they will always pass, even if they are marked as spam (for example, numbers of courier services that you are waiting for).
- 📅 Schedule: Configuring time intervals when blocking is in enhanced mode (for example, at night or on weekends).
Setting up filters allows you to create personalized protection. For example, if you are waiting for an important call from an unknown number (doctor, technician), you can temporarily disable aggressive filtering. To do this, the application interface has a convenient mode switch.
⚠️ Attention: The application interface and menu item names may vary slightly depending on the version of the operating system Android and the model of your smartphone (Samsung, Xiaomi, Huawei, etc.).
What to do if important was the call blocked?
If you find a missed call from an important subscriber in the blocking log, simply add this number to the White List. To do this, open the call log inside the Who Calls application, find the number and select the "Always Allow" option.
Personal data protection and privacy
The issue of data security when using caller ID is especially acute, since such applications theoretically have access to your entire phone book. The company Kaspersky declares strict adherence to the privacy policy. Unlike many free analogues, this product does not sell your data to third parties.
When the application is running, the hash sums of the numbers are checked against the cloud database. This means that your contacts are not transferred in clear text to the company's servers for analysis, but are used only locally for comparison. Data encryption ensures the protection of information during transmission.
Users can see what permissions the application uses at any time through the system settings Android. Transparency of work is one of the key principles on which trust in the brand is based. You are always in control of what data is processed.
It is important to regularly update the application through the official store. Updates often contain not only new features, but also security patches that close vulnerabilities that can be used by attackers to gain access to the device.
Using official applications from well-known security vendors reduces the risk of personal data leakage compared to free analogues from unknown developers.
Solving problems when the detector works
Despite high reliability, users may encounter situations where the application stops identifying numbers or blocking spam. This is most often due to the aggressive power saving built into modern shells Android (MIUI, OneUI, EMUI).
The system can automatically “kill” the detector process to save battery power. To avoid this, you need to find the application in the list of installed apps, go to the "Battery" or "Energy Consumption" section and select the "No restrictions" or "Do not save battery" mode.
Problems may also arise after a major update to the operating system. In this case, it is recommended to clear the application cache through the phone settings. To do this, go to Settings → Applications → Kaspersky Who Calls → Memory → Clear cache. This will not delete your settings, but will help eliminate software errors.
- 🔄 Reboot: The first step in case of any failures is a complete reboot of the smartphone.
- 🔋 Energy saving: Disable the "Super-saving" mode for the detector to work in the background.
- 📲 Update: Make sure that the latest version of the application from Google Play is installed.
If the problem persists, it makes sense to uninstall and install the application again. When re-installing, go through all the steps of setting permissions again, paying special attention to the “Display on top of other applications” item.
Why does the application not see numbers from instant messengers?
Kaspersky Who Calls works with regular telephone communications (GSM/LTE). Calls via WhatsApp, Telegram, Viber and other instant messengers use Internet protocol and do not go through the standard Android calling module, so classic caller ID cannot track them. To protect yourself in instant messengers, use the built-in functions of blocking the applications themselves.
Can I use the application on a tablet?
Yes, the application is compatible with Android tablets, but its functionality will be limited if the tablet does not have a SIM card or voice communication module. Caller ID only works on devices capable of receiving regular phone calls.
Does caller ID affect the speed of a smartphone?
Modern versions are optimized and consume a minimum amount of resources. However, on very old devices with a small amount of RAM (less than 2 GB), the background operation of any additional service may slightly affect performance.
Do you need the Internet for the blocker to work?
A constant Internet connection is not required to block numbers from the blacklist, since this database is stored locally. However, to identify unknown numbers and update spam databases, a periodic connection to the network is necessary.
