The problem of covert surveillance of a smartphone is becoming increasingly important for owners of devices based on Android. Many users Huawei notice strange behavior of the gadget: rapid battery drain, heating of the case in standby mode, or sudden pop-ups. These symptoms often indicate the presence of malicious software designed to intercept data.
Phone owners Honor and Huawei are at particular risk due to the popularity of the brand and the specifics of working with the app store AppGallery. The lack of Google services on new models forces users to download software from third-party sources, which increases the likelihood of infection. It is urgent to diagnose the system if you suspect something is wrong.
Next we will look at a comprehensive approach to identifying and removing spyware. We will analyze both built-in protection EMUIand radical methods for completely clearing the device’s memory. Remember that the speed of reaction directly affects the safety of your personal data and financial information.
Primary diagnosis of suspicious activity
The first step in the fight against espionage is a careful analysis of the behavior of your smartphone. Malware rarely runs without a trace, leaving digital traces in the form of abnormal resource consumption. If you notice that the phone discharged is much faster than usual even with minimal use, this is the first alarm signal.
Pay attention to the temperature conditions of the case. If the phone Huawei gets noticeably warm in standby mode or when performing light tasks, it means that some process is actively using the processor in the background. Often this indicates that recorded conversations or geolocation are being transferred to a remote server.
Check mobile traffic usage statistics. Spyware requires a constant connection to the Internet to send data. Go to the settings and see which application consumes the most gigabytes, especially if it is a service unknown to you or a system utility with a suspiciously high consumption.
⚠️ Attention: A sharp increase in traffic consumption at night, when the phone is idle, is an almost guaranteed sign of the work of a hidden miner or spy.
It is also worth listening to the quality of communication. Extraneous noises, clicks, or echoes during a call may indicate third-party interference with the audio stream. Although modern digital networks make such listening difficult, the presence of specialized Software on the device itself can create such interference programmatically.
Using engineering codes to check forwarding
One of the most effective and A quick way to check whether your calls and messages are being redirected to someone else's number is to use special USSD codes. These commands work at the network equipment level and do not require the installation of additional software. For phones Huawei they are standard and supported by most telecom operators.
Enter the code in dialing mode *#21# and press the call button. A window will appear on the screen with information about the status of all types of forwarding: voice calls, SMS, faxes and data. If the status next to any item is “Not forwarded,” then everything is fine with this setting.
If you see a specified phone number that is not familiar to you, this means that your calls or messages are duplicated to this device. In this case, you must immediately disable this feature. To reset all types of forwarding, use a universal command ##002#.
##002#After entering this command, you should receive a notification from the operator that all forwarding conditions have been successfully deleted. This action blocks the ability to intercept incoming calls through network settings, but does not remove viruses installed directly in the phone's memory.
Save a screenshot of the screen with the results of the scan with the code *#21# before resetting. This may be useful as evidence of interference when contacting law enforcement agencies.
Searching for and removing hidden spyware applications
Most wiretapping apps are disguised as legitimate system processes or have plain-looking icons without a name. To find them, you need to go to the application management section. On devices Huawei with a shell EMUI or HarmonyOS the path looks like this: Settings → Applications → Applications.
Carefully scroll through the entire list of installed software. Look for apps with empty icons, strange names like "System Service", "Update Helper" or "Wi-Fi Tool" that you did not knowingly install. Pay special attention to apps that don't have an icon in the app store or that require suspicious permissions.
- 🕵️♂️ Check apps with device administrator rights, as they may be blocking themselves from being removed.
- 🔍 Sort the list by installation date to find the most recent suspicious ones software.
- 🚫 Pay attention to applications that cannot be removed with the standard "Delete" button.
If you find a suspicious element, try deleting it. If the button is inactive, it means that the malicious app has gained rights Administrator. You need to go to Settings → Security → Device Administrators and uncheck the found application. Only after this can it be uninstalled.
⚠️ Attention: Some viruses disguise themselves as system processes with names like “Android System” or “Google Services Framework”. Do not delete files with such names unless you are 100% sure that they are fake, otherwise the phone will stop working.
☑️ Checking installed applications
System scanning with built-in antivirus
Smartphones Huawei equipped with a built-in security module, which is based on engines from leading anti-virus laboratories, such as Avast or AVL. This tool is often overlooked as not being powerful enough, but it works well against known spyware signatures.
To run the scan, find the application Optimizer (Optimizer) on your desktop or in the Tools folder. Inside, select the "Security" or "Antivirus" section. Click the "Scan" button to run a full scan of the file system and installed applications.
The built-in scanner checks not only files, but also behavioral factors. If it detects a app that is trying to secretly record your screen or microphone, it will suggest removing it or quarantining it. Regular use of this tool helps keep the system clean without installing heavy third-party solutions.
| Threat type | Risk to data | Detection method | System action |
|---|---|---|---|
| Trojan spy | High (password theft) | Signature analysis | Blocking and deletion |
| Adware | Medium (spam) | Permission analysis | Cache clearing |
| Rootkit | Critical (full access) | Integrity check | Isolation process |
| Phishing site | High (card theft) | Analysis of URLs in the browser | Access blocking |
It is important to regularly update the anti-virus databases inside the "Optimizer" application. Without fresh virus definitions, the system may miss new modifications of malicious code that appeared just the other day. The update usually occurs automatically when connected to Wi-Fi.
Huawei's built-in antivirus is effective against mass threats, but to protect against targeted attacks (stalker software), it is better to use specialized solutions paired with manual control.
Analysis of extended permissions and special features
Modern spyware often uses legal ones Android features to operate while bypassing standard security checks. The key mechanism here is Accessibility Services. Attackers use this section to intercept keystrokes and read screen contents.
Go to the menu Settings → Accessibility. Carefully review the list of services that have permission to manage the interface. If you see an app there that is not an official accessibility tool (such as a voice assistant or screen reader), disable it immediately.
Also check the "Manage your device externally" or "Access notifications" section. Spyware often requests access to notifications in order to read codes from SMS messages from banks and instant messengers. Having an unfamiliar application in the list of those who can read your notifications is a critical vulnerability.
Another hidden leak channel is the “Display on top of other applications” feature. Malware can use this to create an invisible layer on top of the screen that intercepts your clicks. Check this list in application settings and revoke rights from all suspicious elements.
Why do viruses ask for access to accessibility features?
This section gives the application full control over the screen and keyboard. Attackers use it to record everything you type, including passwords and card numbers, as well as to automatically press the "Allow" buttons when installing other viruses.
Radical method: full reset to factory settings
If manual removal does not bring results, or you want to be sure to get rid of any possibility of wiretapping, the only reliable solution is a complete reset (Hard Reset). This procedure completely erases all data from the internal memory of the phone, returning it to its out-of-the-box state.
Before starting the procedure, be sure to back up important contacts, photos and documents to external media or cloud storage Huawei Cloud. However, do not restore the backup of your applications immediately after resetting them, as the virus may come back with them. Reinstall apps only from trusted sources.
To perform a reset on a switched off phone Huawei press the volume up and power buttons simultaneously. Hold them until the logo appears, then release the Power button, continuing to hold the volume until you get to the menu Recovery. Select "Wipe data/factory reset" and confirm the action.
⚠️ Attention: The Recovery menu interface may differ depending on the EMUI version. If the touch screen does not work in this mode, use the Volume buttons to navigate and the Power button to select.
Once the process is complete, the phone will reboot and begin the initial setup. This will take a few minutes. Upon completion, you will receive a clean system in which, with a 99.9% probability, no traces of malicious interference will remain. This is the most effective way to remove wiretapping on an Android Huawei phone.
After the reset, do not immediately log into your Google or Huawei account with a password if you suspect that it may have been compromised. First, change the password from another, secure device.
Can wiretapping remain after resetting the settings?
In the vast majority of cases, a full reset deletes all user applications and data, including viruses. The exception is when malicious code has penetrated the system partition (rootkit) or is located on the SIM card/SD card. If the virus was on the memory card, format it too.
Do you need to change the SIM card after removing the spy?
It is not necessary to change the SIM card, since modern spyware lives in the phone's memory, and not on the operator's chip. However, changing the password from the operator’s personal account and the PIN code of the SIM card itself is highly recommended.
How to protect your phone from re-infection?
Do not install applications from unknown sources (APK files from instant messengers or websites). Always keep your Huawei Security Scanner turned on. Update the system regularly through official channels and do not follow suspicious links in SMS.
Will codes like *#06# help you find a wiretap?
Code #06# shows only the IMEI of the device and has nothing to do with diagnosing viruses or wiretapping. To check redirection, use codes #21# and ##002#, described at the beginning of the article.
