In the digital age, privacy has become critical. Owners of Xiaomi smartphones β especially the Redmi Note 12, POCO X5 or Mi 11 β often wonder whether you can quietly listen to your phone through a microphone, camera or network protocols? The answer is ambiguous: technically yes, but it requires either physical access to the device or vulnerabilities in the MIUI firmware.
Rumors of βembedded surveillanceβ on Xiaomi phones have been around for a long time, from the scandal of sending data to servers in China to accusations of cooperation with the government. However, the real threat often comes from third-party spyware installed through phishing links, APK hacked or Android vulnerabilities. In this article, we will examine the unique signs of wiretapping on Xiaomi, which differ from the common symptoms on other brands due to the features of MIUI firmware and integrated services (for example, Mi Cloud or GetApps).
1. Signs of wiretapping: what should alert
The Xiaomi wiretapping is rarely obvious, and the attackers use disguise techniques, but some symptoms reveal their presence:
- π Unexplained battery consumption (e.g., a drop from 100% to 30% in 2 hours in standby mode) is especially noticeable on Xiaomi due to aggressive optimization MIUI β If your phone is discharged faster than usual, check your settings. β Battery β Battery utilization.
- π‘ Increased network traffic in the background. Spyware often transmits data in small packets (5-50 KB), but constantly. β SIM-maps and mobile networks β Data traffic and compare with previous periods.
- π₯ Overheating of the case without loading. If the phone is heated in the processor area (top) or near the microphone (bottom edge), this may indicate that background recording processes are working.
- π€ Noise in the speaker during calls. Listening programs sometimes create echoes or interference due to conflict with Xiaomi's audio drivers.
Pay special attention to the behavior of the phone at night. Many spyware utilities are activated when the device is connected to charging and Wi-Fi, so they disguise themselves as standard MIUI upgrade processes.
Verification through MIUI settings: hidden processes
MIUI firmware contains tools to help identify suspicious activity.
- Analysis of running applications: Go to Settings β Applications β Application Management β Launched. Pay attention to programs with unusual names (e.g. com.android.system.update is a legitimate process, and com.service.secure can be a fake).
- Superuser Rights Check: If your Xiaomi has root access, open Settings β Additional β Developer β Root Rights. Unknown Su Apps β Red Flag
- Download monitoring: In Settings β Battery β Autorun disable all suspicious apps. Spyware is often masquerading as system services (e.g. Google Play Services, but with a typo in the name).
Some legitimate Xiaomi processes may seem suspicious, such as com.miui.analytics, a statistics collection service (which can be turned off in Settings β Privacy β Diagnostics).
βοΈ Quick check. MIUI surveillance
3.Technical methods: ADB, Logistics and Network Analysis
For advanced users, there are ways to do deep diagnostics, which require connecting your phone to a PC and using tools like ADB (Android Debug Bridge).
Step 1: Testing of active compounds
Connect Xiaomi to your computer, enable USB Debugging (Settings β About Phone β MIUI version β press 7 times, then return to Additional β For Developers) and execute the command:
adb shell netstat -tulnpLook for suspicious IP-Addresses (especially from China if you are not using Chinese services) or ports in the range 4444, 5555, 8080 β these are often used for remote management.
Step 2: Analyze the logs
Log unloading command:
adb logcat -d > xiaomi_logs.txtOpen the file. xiaomi_logs.txt And look for keywords: audio_record, On Xiaomi, legitimate microphone recordings (e.g. for Google Assistant) will be tagged com.google.android.googlequicksearchbox.

Step 3: Scanning for viruses
Use specialized antiviruses for Android:
- π‘οΈ Malwarebytes β detects spyware masquerading as system processes.
- π Kaspersky Mobile Antivirus β Checks for Vulnerabilities MIUI.
- π± Bitdefender Mobile Security β Analyzes Network Traffic for Data Leakage.
Important: Before scanning, disable Mi Optimizer (Settings β Special features β Optimization MIUI), as it can block the work of antiviruses.
Physical features: microphone, camera, sensors
Some spyware activates the hardware components of the phone, and here's how to detect them:
| Component | Sign of wiretapping. | How to check |
|---|---|---|
| Microphone | LED near front camera flashes for no reason | Call your phone from another device β if you hear a noise even when youβre not talking, the microphone can be activated. |
| Camera. | The camera lens is slightly heated without using | Close the camera with your finger and illuminate with a flashlight β if dim light is visible, it can work. |
| Gyroscope/accelerometer | The phone spontaneously turns the screen or vibrates | Install the Sensor Box app and check sensor activity in the background |
| Wi-Fi/Bluetooth | The phone is connected to unknown networks | Check Settings β Wi-Fi β Save networks and Bluetooth for unfamiliar devices |
Unique feature for Xiaomi: if in Settings β Privacy β Application Permissions β Microphone you see applications with Chinese characters in the title (for example, βsecurity serviceβ), it can be built-in monitoring software (often found on global firmware for the Chinese market).
π‘
On Xiaomi models with an IR port (like the Redmi Note 11), check if it activates spontaneously. Some spyware uses IR to transmit data over short distances.
5. Verification through the engineering menu and test codes
Xiaomi's hidden menus allow you to diagnose hardware components. Here are the most useful commands:
- π Microphone check: type ##36446337## (for audio test) If the microphone indicator is green without you, it is used by the background process.
- π‘ Network test: ##4636## β Select Usage statistics. Look for unknowns. IP-Addresses in the Network Use section.
- π Battery diagnostics: ##4636## β Battery information: If Awake time is significantly higher than Screen on time, the phone wakes up for background tasks.
β οΈ Not all codes work on new Xiaomi models (e.g. Xiaomi 13 or Xiaomi) POCO F5). On the firmware MIUI 14+ The engineering menu can be blocked. In this case, use the app. MTK Engineering Mode (for MediaTek processors) or Qualcomm Service Menu (for Snapdragon).
6. How to remove spyware: step-by-step instructions
If you find evidence of surveillance, act quickly:
- Turn off the Internet: Put your phone in flight mode or turn off Wi-Fi/mobile data, which will prevent the data from being transmitted to an attacker.
- Remove suspicious apps: Go to Settings β Apps, sort by installation date, and remove anything unfamiliar. Pay attention to apps with administrator rights (Settings β Passwords and Security β Device Administrators).
- Reset: If you're not sure you've found all the software, do a hard reset: Settings β About Phone β Resetting β Erase all the data. Important! Pre-save the data to an external drive, after the reset, it will be deleted.
- Update your firmware: Install the latest version of MIUI through Settings β System Update. New firmware closes vulnerabilities that may have been used to install spyware.
β οΈ If the wiretapping symptoms persist after the reset, it could mean:
- π οΈ Hardware intervention (for example, flashing a bootloader or installing an interceptor chip).
- π‘ Remote management through IMEI (It is rare, but it is possible on phones with modified baseband).
In this case, contact the Xiaomi service center with the requirement to check the integrity of the hardware.
π‘
Setting resets only remove spyware if it was installed as a regular app. If an attacker gets root access, you will need to flash it through Fastboot.
7.Prevention: How to Protect Xiaomi from Eavesdropping
The best defense is prevention. Follow these rules.
- π Turn off unnecessary permissions: In Settings β Confidentiality β App permissions ban microphone, camera, and location access for all but the most essential apps (like WhatsApp or Google Maps).
- π‘οΈ Use strong passwords: Set up complex ones PIN-code or pattern lock (at least 8 points) You can turn on fingerprint protection on Xiaomi + PIN In Settings β Lock screen.
- π Set up. VPN: Install ProtonVPN or NordVPN and enable Always-on VPN (Settings β Additionally. β VPN). It's gonna make it harder to intercept traffic.
- π± Check your device regularly: Once a month, scan your phone for viruses and analyze active processes through the Internet. ADB NetGuard app.
β οΈ Warning: Do not install firmware from third-party developers (such as LineageOS or Pixel Experience) unless you are sure of its security. Modified firmware may contain backdoors for remote access.
