Simple signs to detect a tracked phone

1. Unusual battery drain

If your phone suddenly experiences unusual and rapid battery drain, even when fully charged, and shuts down after a short period of use, this is the first way to detect if your phone is being tracked. Perform the following steps on your phone: Go to Settings > Device care > Select Battery to check which apps are consuming the most battery.

Put power-draining apps to sleep or uninstall them if they are unnecessary. If your phone still drains battery after uninstalling apps, then your phone is being tracked.

2. Rapid depletion of data

If your 3G/4G data or phone credit gets depleted quickly, it is a warning sign that there is malicious software running in the background when you are accessing the internet.

Check your data usage by using the following codes from major network providers:

  • MobiFone data check: Send KT DATA to 999 (200VND/SMS charge).
  • Vinaphone data check: Send DATA to 888 or TRACUU to 900 for free.
  • Viettel data check: Send KTTK to 191 or *098# on your phone’s keypad and follow the instructions.

3. Constant advertisements

If your phone suddenly starts displaying continuous advertisements, sensitive pop-ups, gambling content, and malicious codes, or if you encounter strange characters, this is a sign that your phone is being tracked or infected with malware.

4. Overheating and decreased performance

Continuous tracking apps can increase the temperature of your phone and decrease its performance. If you notice that your phone is hotter than usual or slower without a clear reason, it is also a sign that your phone is being tracked. These intrusive software applications drain the battery and memory. If not detected in time, they can damage your device.

5. Hearing unusual sounds frequently

Pay attention to any strange sounds coming from your phone, such as background noise or beeps at the start of a call. This is a way to detect if your phone is being tracked and calls are being recorded without your knowledge.

6. Receiving anonymous SMS messages

Continuous messages containing strange characters or numbers are sent to you at an increasing frequency. Do not be careless if your phone is being tracked; immediately delete these messages and block the numbers. Never click on any unusual links sent to you.

7. Sudden phone shutdowns

If your phone shuts down and restarts on its own while you are using it, it means that someone has accessed and controlled your phone.

Note: Exclude cases where phones automatically restart due to overload.

8. Check installed apps

One way to detect if your phone is being tracked is to check the management apps or security apps with access to sensitive features. If you find unfamiliar apps or do not remember installing them, it means that your phone has been installed with tracking or spy apps without your knowledge.

Actions to take when your phone is being tracked

After learning about the 8 ways to detect if your phone is being tracked and feeling concerned about your beloved smartphone, there is no need to worry because we will guide you on how to prevent tracking through the following methods:

1. Disable location services

The location function on your smartphone is a smart feature that allows people to share their locations with each other. However, it is also a vulnerability because the apps you install will track you. Disable location services when not in use. For example, only enable it when using certain apps such as ride-hailing or navigation apps, rather than having it enabled 24/7.

2. Change passwords and PIN

First, change the password and PIN of your phone. Choose a strong password that includes letters, numbers, and special characters. This will prevent attackers from accessing your device. Also, change your social media passwords to protect your accounts.

3. Check and remove suspicious apps

Check the list of installed apps on your phone and consider removing unfamiliar or suspicious apps. Uninstall these apps carefully. If you cannot remove a certain app, disable and revoke its access permissions.

4. Remove spyware

Search your phone for any spying software that may be secretly accessing and controlling your device. If found, immediately delete it, as it is the cause of abnormal sounds on your phone.

5. Use anti-tracking software

Some mobile apps are specifically designed to detect and block tracking activities on your phone. Search for and use these apps to protect your privacy.

6. Factory reset

If none of the above methods help you remove the tracker, the last resort is to perform a factory reset of your phone. This will erase all data and apps from your phone, ensuring that no tracking software exists.

Note: Remember to back up your important data before performing this process.

Perform a factory reset as follows:

  • For Android phones: Go to Settings > Tap on General management > Reset > Factory data reset > Reset device.
  • For iPhones: Go to Settings > General > Reset > Erase all content and settings.

7. Visit a reputable repair shop

If you are still unsure or unable to resolve the issue, contact a technology expert or mobile service provider for advice, support, and repairs.
