The Stud Finder app can be used to find studs and metal in the wall. It uses your phone's magnetic sensor to detect any metal that is close to the phone. It will alert you if the level of the line or the magnetic field is high. The app can also be used to find wires and power cords. It is a great tool for anyone who needs to locate wires and power cords. It can also be used to detect metal.

If you have a phone that does not have a working magnetic sensor, or if your magnetic sensor is malfunctioning and providing faulty readings, you will not be able to use the Stud Finder app to find studs and metal.
