How to disable wiretapping on Xiaomi Redmi Note: the full guide

Owners of Xiaomi Redmi Note smartphones often face suspicions of covert surveillance of the device. Modern Android operating systems, especially in the shell of MIUI, collect a huge amount of telemetry, and installing third-party applications can lead to the emergence of real spyware. Understanding how digital surveillance works is the first step to regain control over personal data.

Don't panic if the battery starts to run out faster or the phone gets hotter. These symptoms may indicate background processes, but they're not always a sign of a virus. However, you can't ignore potential privacy threats on a device with access to a microphone and camera. In this article, we'll look at technical ways to detect and block unwanted access to your gadget.

Protection methods range from simple permission checks to complete system resets. It is important to understand that Xiaomi’s default settings are set to be convenient and stats collected, not as anonymous as possible. You will have to revisit many settings yourself to close vulnerabilities.

Analysis of Application Activity and Hidden Processes

The first thing you need to do to check the security of your device is to look at the list of installed programs in detail. Often malware masquerades as system processes or has names similar to legitimate services from Google or Xiaomi. Go to the settings and carefully review all applications, including those that do not have an icon on the desktop.

Pay special attention to applications with device administrator rights. This is the level of access that allows programs to block deletion, track location, and read messages without the user's knowledge. On Redmi Note devices, such rights are often required for antivirus, but can also be used by spies.

You can use developer mode to do deep analysis, activate it, you can access running services, find Working Services in the menu, sort out the memory consumption processes, and abnormally high resource consumption by an unknown process is a direct indicator of a possible threat that requires immediate intervention.

• 🔍 Check the list of applications with administrator rights in the section "Security and privacy».
• 📉 Analyze battery consumption: unusually active app in the background - suspicious.
• 📂 Check the App Manager folder for programs without a name or icon.
• 🛡️ Disable the installation of applications from unknown sources in the security settings.

Verification and restriction of access rights

Android provides granular control over application rights. On Xiaomi smartphones, this functionality is enhanced with its own security system. It is critical to check which applications have access to the microphone, camera and geolocation. Often, ordinary flashlights or calculators request access to contacts, which is a clear sign of data collection.

Recent versions of MIUI have introduced a privacy protection feature that shows the timeline of sensor usage, so you can see when the app turned on the microphone or the camera. If the messenger or game accessed the camera when you weren't using it, that's a cause for concern.

Pay particular attention to Overlay Over Other Windows permissions, which are often used by legitimate pop-up programs, but it is through which phishing forms are embedded and clicks are intercepted, and disable this feature for all applications where it is not vital, such as navigators or voice recorders.

• 🎙️ Go through the list of applications with microphone access and remove the extra.
• 📍 Restrict access to geolocation to “Only when used” mode».
• 📱 Disable access to the call list for all apps except your phone.
• 👁️ Disable file access for applications that do not need to save data.

Privacy settings in MIUI

MIUI is known for its aggressive telemetry collection to improve user experience, and to minimize data leakage, you need to turn off a number of services in your Mi Account and system settings, which won’t take away the virus, but will significantly reduce the amount of information you transmit about your habits.

In the Password and Security section, you'll find Privacy, where you'll need to disable the use and diagnostic data, and you'll need to go to the ad settings and disable personalized recommendations, and that will stop you from creating your digital profile on the company's servers.

⚠️ Note: A complete shutdown of Xiaomi system services may cause some features to malfunction, such as Find Device or automatic theme updates.

Don't forget the service. MSA (MIUI System Ads. Although it's responsible for advertising, it also collects data about your activities. Trying to shut it down will take several attempts, because the system will convince you to leave it on. Patience here is a key factor in successful privacy protection.

• 🚫 Shut down the service. MSA in the menu "Authorization and feedback».
• 📊 Disable the transfer of diagnostic data to the cloud.
• 🔒 Set a complex screen lock password by abandoning simple graphic keys.
• 🌐 Disable automatic connection to open Wi-Fi networks in the wireless network settings.

Use of security modes and antiviruses

The antivirus built into Xiaomi, based on Avast or AVL engines, is able to detect known spyware signatures. Regular system scanning is basic security hygiene. However, it is worth remembering that embedded tools can miss new, unknown threats, so periodic verification by third-party solutions is recommended.

For deep cleaning, you can use specialized utilities such as Malwarebytes or Kaspersky. They have more extensive databases and can find hidden miners or Trojans that masquerade as Android system files. Once you install such an application, conduct a full scan of internal memory.

There's also a Guest or Second Space mode that can be used to isolate suspicious activity. If there's any weirdness in the main profile, create a clean second space and move important data there by deleting the old profile, which is an effective way to break the malware's connection to your primary account.

Radical measures: Resetting and reflashing

If software methods fail and suspicions of wiretapping remain, the only reliable solution is a complete factory reset, which deletes all user data, applications and, most importantly, hides any embedded malware that does not have superuser rights at the system level.

Before you reset, make sure to back up important files, but be careful: don’t save the apps themselves, as you can inadvertently save the virus. Save only photos, contacts and documents. After the reset, do not restore the applications immediately, but install them again from a trusted Google Play store.

⚠️ Before resetting, make sure you remember your Google and Mi Account data. Without them, your device may lock after rebooting due to activation of the theft protection feature (FRP).

For advanced users, there is a method of flashing the device through Fastboot to clean all partitions, which ensures that even threats that may have been entrenched in the system partition are removed, but this method requires technical skills and carries the risk of turning the phone into a brick if executed incorrectly.

• 💾 Backup only personal files, excluding applications and their data.
• 🔄 Reset via the Recovery Menu (Wipe Data/Factory Reset).
• 🔑 Prepare passwords from Google and Mi accounts to unlock after reset.
• 📲 Do not install applications from unknown sources immediately after resetting.

Prevention and safe use

Once the device is cleaned, it is important to follow digital hygiene rules to prevent re-infection, the main reason for the emergence of “wiretapping” is the installation of applications from third-party sources or clicking on phishing links, always check the site’s security certificates and application ratings before installing.

Regularly update your Android operating system and MIUI shell. In security updates, Xiaomi closes vulnerabilities that hackers can access your device. Ignoring updates leaves your Redmi Note open to known exploits.

💡

Use the “Stealth Protection” feature and regularly check the list of trusted devices in your Google account. If you see an unfamiliar gadget there, delete it immediately and change your password.

It is also recommended to periodically check if the forwarding of calls is activated, attackers can set up the forwarding of your calls and SMS to another number, to check the universal code ##002# - it cancels all types of forwarding if they were installed without your knowledge.

💡

The most reliable way to remove wiretaps is a complete reset (Wipe Data) followed by installing only verified applications from the official store.
