Identify Unknown Bluetooth Devices

Fortunately, you can detect strange Bluetooth gadgets or accessories that may have been added to your device and protect yourself from them to make your device safe.

Read on as we explain the different ways to find strange Bluetooth accessories and how to keep your devices safe from them.

How to Find Hidden Bluetooth Devices? Precautions and Solutions

You can find hidden Bluetooth apps and tools by visually inspecting your phone or computer or using tools that can analyze the different apps on your smart device. In addition to that, if you believe the situation is serious, you can use spectrum analyzers or opt for reverse hacking.  

We’ve broken down the different methods below, so make sure to consider each method carefully.

– Visually Inspecting Your Device

The first and most obvious method to check if you have a hidden Bluetooth accessory or device on your phone or computer is by performing a visual inspection.

While it isn’t very reliable, you’ll be able to determine the devices you added yourself and those that are foreign on your device. You’ll need to scan through every accessory on your computer or phone for suspicious devices.

Visually Inspecting Your Device

If you’re checking on a computer, you’ll need to check the body of your PC as well because the malicious user may have attached a tiny device that’s capable of providing Bluetooth signals to your computer.

Keep in mind that these external devices can be so tiny to the point that you may not catch them even after inspecting every inch of your computer.

Some pointers you can consider include looking for devices that have lights or antennas on them or devices that blink when you’re using your computer.

When your computer, smartphone, or other smart devices clearly don’t use antennas or any suspicious device you know you don’t have and have never added to your computer.

– Using Apps that Check for Bluetooth Devices

If you’re looking for how to identify unknown Bluetooth device Android, iOS, or Windows, this method is more reliable than visually inspecting your device.

You can quickly find out if your computer or smartphone has its Bluetooth service turned on when it’s supposed to be off. Find hidden Bluetooth devices apps will search your device for hidden devices and provide you with a list of all the devices on your computer or smartphone.

Note that there are many different Bluetooth checker apps you can choose from. To make the right choice, read through the app reviews and download the one that seems reliable to you. Keep in mind that you may have to pay real money to use some apps or some functionalities in the app.


– Using Spectrum Analyzers

For those who are looking for a more technical way to do things, you can try using a spectrum analyzer to find hidden devices on your computer, smartphone, or in your home. Spectrum analyzers are used to determine radio frequencies and the devices emitting them.

If you use a spectrum analyzer and turn off your normal Bluetooth accessory or device, you can detect the radio frequencies of an active, hidden device as well as where the device is emitting its signal from.

– Using Bluetooth Scanners

While Bluetooth scanners work in the same way as spectrum analyzers, they are more precise as they only scan for Bluetooth signals.

If you’re worried about how to find hidden Bluetooth devices in homes, on your computer, or on your smartphone, getting a Bluetooth scanner may be all you need. The scanner will log onto the device via radio frequencies and show you where the frequencies are being emitted from.

Using Bluetooth Scanners

It’s also useful for those who are considering how to find a lost Bluetooth device that still has its Bluetooth connection turned on.

If you’re looking for how to find a Bluetooth device when it’s off, then you’re out of luck, as no app or tool can track an inactive Bluetooth device.  You can find Bluetooth scanners in different electronic stores, and you can even get them in online stores like Amazon.

– Using Reverse Hacking

This option is reserved for more technical users. While hacking may sound unethical, the person that hid a device on your computer or smartphone probably did it with malicious intent. You can perform a reverse hack using specialized software that’s mainly designed to resolve issues like this.

Once you’ve installed the software, it’ll scan for hidden devices on your computer and provide you with all information about the device, the data being transferred through the device, when it was installed, and other necessary information. You can then use the software to deactivate the device and intercept any data that’s being transmitted from your computer.

How to Remove Unknown Bluetooth Devices after Identification?

You can remove unknown Bluetooth devices after identification by restarting the Bluetooth service on your phone. Moreover, you can opt for ways like updating your operating system or choosing to forget all of the devices that are connected to your device.

– Turn off Your Bluetooth Service

Once you find out you’re connected to an unknown network, the first thing you want to do is turn off your device’s Bluetooth service to make sure that no data is transferred from or to your device.

For instance, if you connect to an unknown gadget or device in a café, you can leave your Bluetooth off until you get home and then try using your Bluetooth again.

– Updating Your Operating System

Keeping your operating system updated can help you flush out hidden devices on your computer. Also, if you choose to reinstall the OS entirely, it can help you remove any malicious device that may have been installed directly on your computer and phone.

Updating Operating System

  6. Your computer will start searching for driver updates and it’ll download one if there’s any available.
  7. After the update has been downloaded and installed, restart your PC and check to see if the problem has been resolved.

– Install an Antivirus or an Anti-Malware

If your Bluetooth service keeps turning itself on, connecting to an unknown network, or you’re unable to delete a suspicious driver on your computer, installing an antivirus or anti-malware may be what you need to do.

Install an Antivirus or an Anti-Malware

There are many different antivirus and anti-malware programs you can utilize, including Avast, Norton, McAfee, Malwarebyte, and more.

Windows also has the built-in Windows Defender, which is more than enough for most people. Once you’ve installed an antivirus or anti-malware program, run a scan on your computer to determine if you have a virus or malware installed.


That’s all on how to identify unknown Bluetooth devices on iPhone, Android, as well as your computer, and the solutions you can try to remove them or fix any related issues.

Here’s a quick recap to make sure you have all you need:

  • If you’re constantly getting unknown device errors, you may have a virus on your computer or an outdated Bluetooth driver.
  • Make sure to always turn your device’s Bluetooth off when you’re in public.
  • Install an antivirus on your device and perform a complete scan to determine whether or not your computer has been compromised.
  • Make sure you don’t connect to devices you’re not familiar with.

If you’ve tried the solutions listed above and none of them seem to work, you may want to consider reinstalling your entire operating system and giving your device a new start. Always turn off your Bluetooth functionality when it’s not in use.
