In order to ensure privacy and avoid unnecessary damage from being wiretapped, it is advisable to use multiple methods to detect hidden listening devices in a room.
Methods to detect hidden listening devices in a room
Here are some effective and accurate methods to detect hidden listening devices in a room.
Using a smartphone
One popular method to detect hidden listening devices in a room is by using a smartphone.
You can detect hidden listening devices by making a phone call. If there is no abnormal sound while the phone is ringing, it means there are no hidden listening devices in the vicinity. However, this method is not always accurate as there can be other factors causing interference with the phone signal.
You can also use the video recording mode to scan the room. If you see a blinking light spot on the screen, it might indicate the presence of a hidden listening device.

Additionally, there are many free smartphone applications available that can detect hidden listening devices. However, the security of these applications is not highly rated, as you need to accept their terms and conditions, which may result in your personal information being stolen. Therefore, it is advisable to consider the risks before installing such applications.
Using a specialized device
You can also use a specialized device to accurately detect hidden listening devices. These devices are also known as signal detectors and are modern technological products. However, this method requires a relatively high cost, depending on the user’s financial conditions.
Observing carefully with the naked eye
Observing every corner of the room carefully is also one of the methods to detect hidden listening devices. Some audio recorders will have a flashing light when they are activated. You need to turn off the lights and search for any glowing LED lights in the room. Additionally, do not overlook objects or corners that could be hiding places for sophisticated listening devices.
Using “white noise”
If you are still concerned about the presence of hidden listening devices in the room, you can play “white noise” on your computer or mobile phone to prevent the eavesdropper from listening.
Signs that your phone may have spyware installed
Spyware installed on a mobile phone allows someone to remotely monitor and listen to your conversations without your knowledge. Below are some signs that indicate your phone may have spyware installed.
Sudden drop in battery life
Over time, you will notice that the battery of your phone does not last as long as when you first purchased it, which is normal. However, if you observe a sudden drop in battery life, you need to consider the possibility of spyware.
Spyware on a phone can consume a considerable amount of resources, as it operates in the background, runs GPS, and performs other tasks. Therefore, if you notice a rapid decrease in battery power without using your phone, it may indicate that your phone has spyware installed.

Check mobile data usage
Spyware on a phone usually consumes a significant amount of mobile data to perform its functions. If you notice any unusual data usage, you should check if it is due to spyware.
Sudden increase in phone temperature
There can be many reasons for this, such as using the phone for an extended period, charging the device with a poor charger, or background applications running. However, if your phone becomes excessively hot, you should consider the possibility of spyware.
Strange sounds during phone calls
In some cases, poor call quality, signal loss, or other factors can create strange sounds. However, if you frequently hear beeps, echoes, or white noise during phone calls, it is advisable to check for spyware on your phone. It is better to be cautious.
Automatic phone power on/off
If your phone powers on or off suddenly without any manual input or control, it may indicate the presence of spyware on your phone.
Receiving strange text messages
If you receive strange text messages consisting of a series of incomprehensible letters and numbers, similar to a code, it may indicate that someone is using them to communicate with the hidden listening device.
