It’s possible that a phone’s electromagnetic signals may interfere with a spy device detector’s accuracy. This is because most detectors use similar frequency ranges as mobile phones, which can cause interference. However, this interference is usually minimal and doesn’t affect the device’s overall functionality.
Some detectors are designed to ignore common signals like those from phones, ensuring more accurate results. Additionally, it’s recommended to keep your phone away from the detector while scanning to minimize interference. Overall, while a phone’s signals may cause interference, it’s not a significant concern for most users. If interference occurs you can also temporarily put your phone into flight mode to prevent it from emitting any signals.
