FAQs about Device Detector
Browse the most frequently asked questions that you may interested in.
What does the Device Detector app do?
Device Detector is a Bluetooth device finder and metal detector app. It can help you locate nearby Bluetooth devices by estimating distance from the Bluetooth signal, and it can detect nearby metal objects (e.g., keys, small screws, or wires in a wall) using your phone’s sensors.
How does Device Detector find devices or metal objects?
The Bluetooth finder estimates how close a Bluetooth device is based on Bluetooth signal strength. The metal detector feature uses your phone’s built-in magnetic sensor (magnetometer) to measure magnetic field changes that may indicate nearby metal.
