How to Enable and Configure Spam Protection on Xiaomi

Owners of smartphones Xiaomi, Redmi and POCO They often encounter intrusive advertising and unwanted calls that can disrupt productivity. MIUI HyperOS offers powerful tools to combat this, but they are not always activated by default. Effective spam protection requires the correct initial configuration of the built-in filters.

Ignoring these settings can lead to personal data leakage or malware infection through phishing links. In this article, we will detail the algorithms for maximum protection of your gadget from information debris. You will learn how to manage blacklists and configure smart message filters.

A systematic approach to security starts with understanding how the standard Security application works, and it's this system component that monitors incoming traffic and analyzes caller behaviors, and when you set up properly, you can forget about annoying service offers.

Analysis of built-in antivirus and application Security

The central element of protection in the Xiaomi ecosystem is the pre-installed Security app, which combines the functionality of antivirus, memory cleaner and, most importantly for our theme, a smart call blocker. Antivirus databases are regularly updated through the company’s servers, allowing you to identify new threats in real time.

To get started, you need to make sure that all components of the application are updated to the current version. Often users neglect this step, relying on factory settings, which may be suboptimal.

⚠️ Note: Do not disable the system application Security even if there are third-party antiviruses, as it has deep permissions to access the system of calls that third-party software cannot get.

There are many useful features hidden inside the app that you can't see on the home screen, such as setting up scans of installed apps for ad modules, which prevents pop-up ads from appearing in unexpected places on the interface.

Setting up a call blocker and SMS

To activate full protection, go to the Security → Antivirus → Settings (cog icon) menu. Here is the Antispam section that needs your attention. This is the menu that sets the logic for processing incoming connections.

Turn on the Spam Block switcher if it is turned off. After activation, an extended menu will open where you can select the level of filtration severity. For most users, the best choice is the Smart Block mode, which analyzes the complaint base of other users.

Special attention should be paid to the filtration setting SMS. In the same section, you can activate blocking messages containing keywords such as "credit", "win" or "promotion" and this will significantly clear your notification panel of visual noise.

Remember to check the lock log periodically, sometimes important notifications from delivery services or courier services using short numbers can be received, and the system allows you to quickly unlock the number directly from the call log.

Managing a blacklist of contacts

Manual contact management is a method that gives the user full control over who can reach them, and you can add a specific number to the Blacklist through the standard Phone or Messages app.

To add a number, open your call history, click on the contact information icon, and select the "Block" option, and then all calls from that number will be automatically reset, and the caller will hear the signal busy or beeping, depending on the operator's settings.

It also has a feature that locks all unknown numbers, which are not in your phone book, a radical but effective method that is often used by people who expect to call only from a particular circle of people.

Advertising filtering in system applications

One of the features of MIUI is that it has ads in system applications like Explorer, Music or Themes, and although it's not exactly spam in the classical sense, these banners are annoying to many users, and you can turn them off through special settings.

You will need to go to the settings of each application separately or use the global switch in the Settings menu → Passwords and Security → Access to personal data. However, a more effective method is to disable the msa service (MIUI System Ads).

Find msa in the application list and turn it off. The system will try to dissuade you by showing you a 10 second countdown timer, which is standard behavior, you just have to wait until the end and confirm the action, and then the number of advertising integrations in the interface will be significantly reduced.

Protection against phishing and malicious sites

Spam is often only the first stage of an attack, followed by a redirect to phishing resources.The built-in Mi Browser browser and the standard Chrome on Android have their own security mechanisms that need to be activated.

In your browser settings, look for the Privacy and Security section and make sure that the option "Safe browsing" is enabled. URL-Google and Xiaomi database addresses, warning of danger before page loads.

Also, avoid installing apps from unknown sources.Even if the link came from a supposedly familiar person, always double-check the source.The Android operating system on Xiaomi smartphones blocks installation by default APK-files from the outside, and to remove this block is only with complete confidence in the file.

💡

Use DNS with ad filtering, such as dns.adguard.com, in the settings of the private DNS (Settings → Connection and Sharing → Private DNS).

Use of third-party solutions and additions

If built-in facilities are not enough, the market offers a plethora of third-party applications, such as Truecaller or Kaspersky Who Calls. They use their own huge number databases, which are often updated by the user community.

When installing such applications, Xiaomi will request extended permissions, you will need to give access to contacts, call logs and SMS. Without these rights, the application will not be able to analyze incoming traffic and verify numbers with the spammer database.

⚠️ Note: By installing third-party number detectors, you agree to transfer your contacts to the developer servers.

For maximum efficiency, you can combine methods: use the built-in Xiaomi blocker for SMS and basic protection, and a third-party application – only to determine numbers, without saving your call history in the cloud.
