A modern smartphone stores more personal information than the secret archives of the intelligence services twenty years ago. From geolocation to messaging in instant messengers, all this can become accessible to attackers or intrusive advertising algorithms. Users are increasingly wondering how to remove Android phone tracking in order to regain their digital privacy.
The problem is that surveillance methods are constantly evolving. If previously it was enough to simply turn off GPS, today there are complex Trojans, system backdoors and legal but aggressive marketing tools. In this article, we will look at how to identify hidden threats and completely secure your device.
Do not panic if you notice strange behavior of your gadget. In most cases, the situation can be corrected on your own, without resorting to the expensive services of service centers. The main thing is to act consistently and understand what type of surveillance is used in your case.
Diagnostics of hidden threats and spyware
The first step towards security is identifying the problem. Spyware Often disguised as system processes or harmless utilities. Pay attention to indirect signs: the battery discharges faster than usual, the device heats up in standby mode, and Internet traffic is consumed abnormally quickly even without actively using the browser.
Go to the settings and carefully study the list of installed applications. Look for apps with suspicious names, invisible icons, or ones you don't remember installing. Pay special attention to access rights. If a simple flashlight or calculator requires permission to read SMS, access to the microphone and geolocation is a clear alarm signal.
For a deeper scan, you can use specialized anti-virus software scanners. However, remember that some advanced viruses can hide even from them. In such cases, manual analysis through developer mode or viewing active device administrators helps.
⚠️ Attention: If you find an application that is not removed in the standard way (the "Delete" button is inactive), most likely it has received administrator rights. Do not try to remove it by force through third-party utilities, this may lead to a system lock.
Disabling system telemetry and advertising identifiers
Even without viruses, your smartphone collects a lot of data about you for Google and hardware manufacturers. This is called telemetry. To minimize this fee, you need to change the privacy settings in the system core itself.
Start with the advertising identifier. This is a unique code that allows advertising networks to track your interests and show targeted ads. To reset it, go to menu Settings → Google → Advertising. Here you need to select the option “Remove advertising identifier” or “Opt out of personalized advertising.”
Next you should disable location history. Google Maps and other company services often save your route with meter accuracy. You can disable this function via path Settings → Google → Privacy → Manage data in your Google account. Find the "Location History" section and pause recording.
Regularly clear your search and YouTube history in your Google account to prevent the algorithms from building an overly accurate profile of your interests.
Don't forget to check the permissions for the voice assistant. Often Google Assistant or Bixby have access to audio recording in the background. Limit their activity or disable the "Ok Google" feature when the screen is off.
Managing app permissions and sensor access
Controlling which apps have access to which phone features is fundamental to digital hygiene. Many users thoughtlessly click “Allow” during the first installation, allowing access to the camera, contacts and microphone.
Check the access rights. Go to Settings → Applications → Permission Manager. Go through each item, especially "Location", "Microphone" and "Camera". Make sure that only those apps that really need it to work have access.
Applications running in the background are especially dangerous. Even if you close the app, it can continue to transmettre data. In the battery settings, find a list of applications with high energy consumption in the background and limit their activity.
| Resolution type | Risk level | Who can be trusted | Recommendation |
|---|---|---|---|
| Geolocation | High | Navigators, Taxi | Allow only "During use" |
| Microphone | Critical | Voice recorder, Messengers | Check the list regularly |
| Contact | Average | Phone, Social networks | Prohibit for games and utilities |
| SMS | Critical | Banking applications | Block everyone except banks |
The principle of least privilege: the application should have access only to the data without which it physically cannot perform its main function.
Checking active device administrators
One of The most insidious way to secure surveillance is to obtain device administrator rights. Malicious software with such rights can block deletion, intercept passwords, and completely control the phone.
To check the list of administrators, go to the security section. The path may differ depending on the model: Settings → Security → Device Administrators or Settings → Biometrics and Security → Other security settings.
In the list that opens, you will see applications that have advanced rights. Usually there should only be “Find My Device” and corporate clients if the phone is working. If you see an unknown application with a check mark, uncheck it immediately.
⚠️ Attention: After removing administrator rights from a suspicious application, it may try to resist removal or display an error. In this case, reboot the phone into safe mode and remove it from there.
If the standard menu does not show all active profiles, you should use the command via USB debugging. Connect your phone to your computer and enter the command to display a list of active administrators.
adb shell dumpsys device_policy | grep "Active Admin"This command will display a technical list of all active components. If you see strange packages there with names like com.system.update.fake, this is a reason for immediate cleaning.

Reset settings and radical cleaning methods
If manual removal does not help, and the phone continues to behave suspiciously, the only guaranteed way remains is a full reset to factory settings. This will remove all data, including hidden viruses and Trojans.
Before starting the procedure, be sure to back up important contacts and photos, but do not save a backup copy of installed applications. Restoring from a full copy may return the virus back to the system.
Reset through the menu: Settings → System → Reset settings → Delete all data (factory reset). The process will take a few minutes, after which the phone will be like new.
What to do if the virus returns even after a reset?
If the malware survives after a full reset, then it is not located in the user partition, but in the system partition or even in the bootloader. This is only possible if you have root access in the past or if you installed custom firmware with a backdoor. In this case, you need to completely flash the device via a computer using official utilities (Odin for Samsung, Mi Flash for Xiaomi, etc.).
After the reset, set up the phone as a new device. Don't log into your old Google account right away if you suspect that synchronization is causing the leak. First, install a reliable antivirus and check the system in a “clean” state.
Protection against advanced network tracking
Even a clean phone can transmit data through network connections. Providers and owners of Wi-Fi points can see which sites you visit if the connection is not encrypted.
Use the "Private DNS" feature available in Android 9 and higher. This allows you to encrypt DNS queries, hiding the list of domains you are accessing from your ISP. In the network settings, select Private DNS and enter the address of a reliable provider, for example, dns.google or 1dot1dot1dot1.cloudflare-dns.com.
It is also recommended to use VPN services with the Kill Switch function. They create an encrypted tunnel for all traffic. However, choose only proven paid services, since free VPNs often collect and sell your data themselves.
⚠️ Warning: Enabling a VPN can slow down the Internet speed and increase battery consumption. Use it only when working with sensitive data or on public Wi-Fi networks.
Avoid connecting to open Wi-Fi networks in cafes and airports without protection. Attackers can create an access point with the same name as a legitimate network and intercept all your traffic (Man-in-the-Middle attack).
Frequently asked questions (FAQ)
Is it possible to track a switched off phone?
Technically, if the phone is completely switched off (not in sleep mode, but is de-energized), it cannot transmit a signal. However, modern smartphones with UWB chips or features like "Find My" from Apple/Google can transmit a Bluetooth signal even with a low battery for some time, using a network of other devices nearby to transmit coordinates.
Will a factory reset remove the virus?
In 99% of cases, yes. Resetting removes the user data partition, where regular applications and Trojans live. The exception is when malicious code is embedded in the system partition (which requires root access) or is in malicious firmware.
How can I find out who called my phone if I didn’t answer the phone?
It’s difficult to do this on your own without special caller ID applications that have access to databases. However, if the phone has spyware, an attacker can receive logs of all incoming and outgoing calls remotely.
Is it safe to use incognito mode to protect against surveillance?
Incognito mode only protects against saving browsing history and cookies on the device itself. It does not hide your IP address from websites, does not protect against tracking by your Internet provider, and does not protect you from keyloggers or network sniffing.
Do you need to seal the camera on your phone?
This is a mechanical method of protection that is effective against software hacking of the camera. If you're worried that malware might secretly turn on your camera, taping the lens is a simple and reliable solution, although not aesthetically pleasing.
