Spy Hidden Camera Detector App is a tool that can be used to detect hidden cameras and microphones. It uses the phone's built-in magnetic sensor to detect any magnetic field that might indicate a camera or microphone is present. It scans every part of your room, including the walls, the ceiling, the floor, and even the lights and switches.

It works by analyzing the magnetic field strength and detecting any objects that have a magnetic field. Once it finds one of these devices, it will alert you and allow you to check it out. You will get a notification when a device is detected.
