The question of how to track WhatsApp on another Android phone worries many users today. Most often, this need arises from parents who want to monitor the safety of their children on the Internet, or from employers who check corporate devices. However, there is also the other side of the coin - the desire to protect yourself from unauthorized access to personal correspondence. Understanding the technical aspects of the messenger's operation is critical to preserving digital sovereignty.
It is worth immediately defining the strict boundaries of reality. Hidden installation of spyware on someone else's smartphone without physical access to the device and an unlocking password is technically impossible in modern versions of Android. Google's security system is constantly being improved to block unauthorized access attempts. Any services on the Internet that promise to “find out correspondence by phone number” in five minutes are fraudulent schemes aimed at stealing your data or money.
In this article we will analyze exclusively legal and technically sound methods of monitoring activity. We will look at the built-in functions of the messenger itself, the capabilities of the operating system Android for parental controls, as well as methods for analyzing backup copies. In addition, you will learn how to detect if your own device is being tracked and what steps to take to protect your privacy.
Legal methods of monitoring through official functions
The most reliable and secure way to find out what is happening in your WhatsApp account is to use the built-in tools of the application itself. The developers have provided the “Linked Devices” function, which allows you to see all the gadgets that have access to correspondence. If someone tries to read messages from a computer or tablet, this information will be displayed in the profile settings.
To check, you need to go to the application settings menu on the target device. Navigation usually looks like this: Settings → Associated devices. This displays a list of all active sessions, including device model, last login time, and browser. If you detect an unfamiliar device, for example Google Chrome (Windows) or Safari (MacOS)that you did not connect, this is a direct signal of interference.
It is important to understand that connecting a new device requires physical access to the phone for scanning QR code. Without unlocking the screen, an attacker will not be able to authorize his gadget. However, if the phone was left unattended even for a couple of minutes, the risk of compromise increases many times over. Checking this section regularly should become a habit
⚠️ Attention: The Linked Devices feature only shows active sessions. If the spy has already completed the session and logged out, the traces in this menu will disappear. To permanently record events, other methods are needed.
In addition to active sessions, it is worth paying attention to privacy settings. In the Settings → Privacy section you can manage the visibility of the “Been recently” status, profile photo and message reading status. Limiting the visibility of these settings makes it more difficult for a potential observer trying to analyze your activity indirectly.
Enable two-factor authentication in WhatsApp settings. This will add a PIN code that will be required when trying to register your number on another device, which will significantly increase the level of protection.
Parental controls and family groups
For parents who want to ensure the safety of children online, there are specialized tools that do not require violation of privacy in a criminal sense. The Android operating system offers a native solution - Google Family Link. This application allows you to create a family group, where the adult is the organizer and the child is the participant.
By installing Family Link on the child’s phone, the parent is able to track the time they use applications, including WhatsApp. Although you will not be able to read the contents of messages directly for ethical and encryption reasons, you will see statistics: how much time is spent on correspondence, what time of day the child is most active and which contacts are most often used.
- 👨👩👧👦 Ability to set time limits for using the messenger.
- 📍 Tracking the geolocation of the device in real time.
- 🚫 Blocking the installation of third-party applications without permission.
- 📊 Viewing detailed activity statistics by day and week.
The use of such tools requires an open dialogue with the child. Hidden installation of such apps can undermine trust. It is better to explain that control is carried out for the sake of safety, and not out of a desire to invade personal space. In emergency situations, the ability to quickly determine the location of a child can save a life.
In addition, there are specialized applications from antivirus companies, such as Kaspersky Safe Kids or ESET Parental Control. They offer advanced functionality, including monitoring social networks and instant messengers for dangerous content. These solutions work legally and require installation on both devices with the consent of the owner.
Analysis of backups and cloud storage
One of the most technical ways to access correspondence history is to analyze backups. WhatsApp automatically creates backups of messages and media files to cloud storage: Google Drive for Android devices. If you have access to the Google account linked to your phone, you can see the date and size of the last backup.
Directly reading database files from Google Drive is not possible for the average user because they are encrypted. However, if you know your Google Account password, you can restore your backup to another device. To do this, you need to install WhatsApp on a new phone, enter the same phone number and, when prompted to restore data from the cloud, agree to this operation.
This method has significant limitations. Firstly, when restoring a copy on a new device, the session on the old phone may be terminated, which the owner will immediately notice. Secondly, you will only get access to the message history at the time the last backup was created. New messages received after this point will not be displayed.
| Parameter | Local copy | Google Drive | Third-party services |
|---|---|---|---|
| Accessibility | Only with the file system | Via Google account | Requires software installation |
| Encryption | High (key on the device) | High (binding to account) | Depends on the developer |
| Risk of detection | Low (with a competent approach) | High (notifications, session reset) | Medium (requires access) |
| Relevance | Until the copy is created | Until the copy is created | Real time |
It is worth noting that local backups are stored in the phone memory in a folder /Android/media/com.whatsapp/WhatsApp/Databases. The files have the extension .db.crypt14 (or other encryption version number). Without a special decryption key, which is stored in the system partition of the phone, these files are simply a set of encrypted data.
How to decrypt the database?
Decrypting a local copy requires root access to the phone and extracting the key file. Without this file, messages cannot be read, even with the database itself. This is done to protect against phone theft.
Specialized monitoring software
There is a category of software on the market positioned as solutions for monitoring employees or protecting children. apps such as mSpy, FlexiSPY or Hoverwatchrequire full installation on the target device. They work in the background and can send screenshots, keystroke logs and copies of messages to the license owner’s server.
Installation of such software is not possible remotely. You will need physical access to your phone for 10-15 minutes to download the installer, disable Play Protect, and provide all necessary permissions. In modern versions of Android, the system will constantly warn that the application has access to special features, which makes hidden use extremely difficult.
Using such apps is associated with legal risks. In most countries, installing spyware on an adult's device without their knowledge is a criminal offense. Legal use is permitted only in relation to minor children under guardianship or corporate devices owned by the company, about which employees must be warned by a signature.
⚠️ Attention: Downloading “spyware” from unverified sites often leads to infection of your own device with stealth viruses. Fraudsters disguise malware as surveillance tools.
Technically, such applications use accessibility services (Accessibility Services) to intercept notifications and content on the screen. This is a powerful tool that gives the application complete control over the interface. This is why Android asks for confirmation every time a new application tries to obtain these rights.
☑️ Check for hidden software
How to understand that your WhatsApp is being watched
If you suspect that you have become a victim of surveillance, you need to conduct a thorough diagnosis of the device. The first sign of interference is often abnormal smartphone behavior. For example, rapid battery drain may indicate that there is a process running in the background that is transferring data. Overheating of the device at rest is another alarming symptom.
Pay attention to outgoing Internet traffic. Go to settings Connections → Data Usage and analyze the list of applications. If you see an unknown application that is consuming a lot of data, or if WhatsApp itself is using an abnormally large number of megabytes in the background without active correspondence on your part, this is a cause for concern.
It is also worth checking the list of applications that have device administrator rights. Go to Settings → Security → Device administrator applications. There should be nothing here other than standard Google services, Find My Device, and perhaps enterprise software if the phone is working. The presence of suspicious names or applications without an icon requires immediate removal.
- 🔋 Rapid battery drain and case heating.
- 📉 Unusually high consumption of mobile traffic.
- 📲 The appearance of unknown icons or processes in the task manager.
- 🔔 Strange behavior of the phone (self-rebooting, turning on the screen).
Another indicator may be strange messages in chats that you did not send, or notifications about logging into your account that come to your email. WhatsApp sometimes sends emails indicating that your number has been registered on a new device. You cannot ignore such letters - this is a direct sign that someone is trying to take over your account.
The most reliable way to remove surveillance is to completely reset the device to factory settings. This will remove all hidden applications and return the system to a clean state.
Protection against unauthorized access
To keep your account and device as secure as possible, you must maintain digital hygiene. Never leave an unlocked phone unattended, even for a short time. Set a secure screen lock method: your pattern is easy to spy, so it's best to use a complex PIN or biometrics.
Change your Google Account passwords regularly and enable two-step verification wherever possible. In WhatsApp itself, this function is located in the Settings → Account → Two-step verificationsection. Create a six-digit PIN that only you will remember. This will prevent your number from being registered on someone else's phone, even if an attacker intercepts an SMS with a verification code.
Be careful with public Wi-Fi networks. Connecting to open hotspots in cafes or airports makes your traffic vulnerable to interception. Although WhatsApp messages are end-to-end encrypted, the metadata and connection may be visible. Use a VPN to create a secure tunnel when working in public places.
Update your operating system and the WhatsApp application itself in a timely manner. Developers are constantly closing vulnerabilities that can be exploited by hackers. An outdated version of the software is an open door for exploits that allow you to inject malicious code without the user's knowledge.
⚠️ Warning: Do not install modified versions of WhatsApp (for example, WhatsApp Plus or GBWhatsApp). These applications do not have an official security certificate and may contain built-in mechanisms for mod developers to steal your data.
Frequently asked questions (FAQ)
Is it possible to read other people's WhatsApp messages without access to the phone?
No, it is technically impossible. WhatsApp uses end-to-end encryption and the decryption keys are stored only on the user's device. Without physical access to your phone or Google account to restore a backup, you cannot read the correspondence.
How to remove a linked device from WhatsApp?
Go to the menu Settings → Linked devices. Click on the suspicious device in the list and select the “Exit” option. This will immediately break the connection, and the user on the other device will lose access to the correspondence.
Is it safe to use parental control applications?
Yes, if you use official applications from well-known developers (Google, antivirus companies) and install them with the consent of the child. Avoid dubious apps from unverified sources that promise “total invisibility.”
What should I do if I received a message about a WhatsApp verification code that I did not request?
Never share this code with anyone. This means that someone is trying to log into your account. Immediately enable two-step verification in the app settings for added protection.
Can police or intelligence agencies track WhatsApp?
Due to end-to-end encryption, even intelligence agencies cannot read the contents of messages in real time. They can request metadata (call time, participant numbers) from Meta or gain access to the phone by physically removing the device.
