How to disable wiretapping on Xiaomi: Expert guide

Owning a modern Xiaomi smartphone provides access to powerful technologies, but at the same time creates risks of leaking confidential information. Device owners often face intrusive advertising, strange calls or simply feel that their personal data can be compromised. The concept of “wiretapping” in the context of Android smartphones covers a wide range of threats, from the banal collection of statistics by advertising trackers to the introduction of malware that transmits audio and video from the camera.

Before panicking, you need to make an objective assessment of the situation. Often users confuse aggressive personalization of advertising with real espionage. However, you can not ignore potential threats. In this article, we will discuss in detail how to diagnose the presence of covert surveillance on your Redmi or Poco, and provide step-by-step instructions for blocking unwanted access to the microphone, camera and geolocation.

Effective protection requires a comprehensive approach that includes setting system parameters, analyzing installed applications and, in extreme cases, completely resetting the device. Data security is a continuous process, not a one-time action. Below are proven methods to help you regain control of your gadget.

Diagnosis: Signs of Hidden Surveillance

The first step to fixing the problem is accurate diagnosis. Modern versions of the MIUI shell and HyperOS have built-in indicators that signal background processes. If you notice that the activity indicator (green or orange dot in the corner of the screen) lights up when you are not using the camera or voice recorder, this is a direct signal to action.

In addition to visual markers, there are indirect signs of system compromise, and anomalous power consumption often indicates that an application is constantly using CPU and network resources to transmit data, and you should also pay attention to the heating of the case in idle mode and a sharp increase in mobile traffic consumption.

⚠️ Note: If your smartphone suddenly starts to issue quiet clicks during a conversation or the screen flashes strangely when incoming calls, immediately check the list of installed applications for unknown programs.

You can use an engineering menu or third-party utilities to analyze it more deeply, but even basic battery statistics can detect suspicious activity. Pay attention to applications that consume energy in the background, especially if they are not navigators or messengers.

Configure access rights to MIUI and HyperOS

The main attack vector for data collection is excessive permissions, which users often give to applications thoughtlessly. In the shells of Xiaomi, there is a detailed permission manager to limit access to sensitive modules. Go to Settings → Privacy Protection → Permissions Management.

Here, you need to check three critical parameters: microphone, camera and location. Make sure that only the applications that really need it to work have access to these functions, for example, a flashlight does not need access to the Internet, and a calculator does not need access to your geolocation.

• 🔍 Check the list of apps with microphone access and disable all the extra ones.
• 📍 For geolocation, select the "Only in use" mode so that tracking is conducted only in the active window.
• 🚫 Disable access to contacts for games and simple utilities.

Special Rights: This section contains settings that allow applications to block other windows or operate without restrictions in the background. Malware is often disguised as system processes, so carefully study the names of packages.

Analysis and removal of suspicious applications

Often, third-party applications or even legitimate programs with embedded ad code are the source of data leaks. Xiaomi owners should regularly audit installed software. Go to Settings → Applications → All applications and carefully review the list.

Look for programs without an icon, with an empty name, or those you don't remember installing, and these applications are often disguised as system services, such as System Service, Update Center, or using a standard calculator icon, and removing these objects is a top priority.

If the standard methods of removing the application fail (the "Delete" button is inactive), then it has the administrator rights of the device. To fix this, go to Settings → Passwords and Security → Privacy → Special Rights → Device administrators. Uncheck the suspicious application, after which it can be uninstalled.

Remember that even popular apps can collect redundant data. Use the Permission Manager feature in the GetApps store or Google Play to see what data the program requests before installing.

Use of built-in antivirus and scanner

Xiaomi has a powerful security tool, developed by Avast or AVL (depending on the firmware version), which you should not ignore, since it has access to deep layers of the system. Launch the Security app and press the Security Check button.

The scanner not only checks for known virus signatures, but also analyzes application behavior; it can detect Trojans, miners, and spyware that masquerade as legitimate software; and regularly updating antivirus databases is critical to detecting new threats.

In addition to full check, use the Scan on Installation feature, which automatically checks all downloads. APK-This creates an additional barrier to malware from entering your system.

Blocking Ads and Trackers Through DNS

A significant part of the “wiretapping” in Xiaomi smartphones is associated with advertising identifiers and trackers that track your actions for targeted advertising. The most effective way to do this channel is to use a private DNS. This method does not require root rights and works at the system level.

To set up, go to Settings → Connection & Sharing → Private DNS. Select the option “Host Name of the DNS provider” and enter the address of a trusted server that blocks ads, such as dns.adguard.com. Once you save the connection, many advertising requests will simply cease to pass.

This method also helps prevent the smartphone from communicating with malware management servers (C&C servers).If the virus attempts to send stolen data, the request will be blocked at the DNS level.

• 🛡️ Entering dns.adguard.com blocks most advertising trackers.
• 🚀 Accelerates page loading by weeding out advertising debris.
• 🔒 Increases privacy by hiding your visit history from your provider.

⚠️ Note: When using a third party DNS Make sure you enter the address correctly. An error in one character can result in a complete lack of Internet access on the device.

💡

Use DNS services that support DNS-over-TLS so that your traffic can’t be intercepted or spoofed on the way to the server.

Radical measures: Resetting and protecting your account

If the software methods didn't work and you're sure there's a deep systemic infection, you're just going to have a full factory reset, and this action will delete all the data, applications and settings, and put the phone back out of the box. Resetting is a guarantee that any bookmarks will be removed.

Before the procedure, be sure to save important photos and contacts, but do not restore the backup of applications immediately, as the virus can return with them. perform a reset via the Settings menu → About the phone → Reset settings → Erase all data.

Once reset, it is critical to change passwords from all important accounts: Google, Mi Account, social networks and banking applications. The password from the Mi Account is especially important, as it gives access to the cloud and the search function of the device.

💡

Full data formatting reset is the only 100% way to remove the complex ransomware viruses and rootkits that are hidden in the system partition.

Remember to update your operating system regularly. Xiaomi engineers are constantly releasing security patches that close vulnerabilities through which attackers can access the device. Activate an automatic update in the Settings → About Phone menu.
