To install the magnetic sensor, first open your phone’s Settings menu. From here, select Security and then Magnetic Sensor. You’ll see a list of compatible devices and a button to install the sensor. Once the sensor is installed, open your app drawer and find the Magnetic Sensor app. Tap on it to start using it. The first time you use it, you’ll need to set up your device’s location by following the on-screen instructions. The Magnetic Sensor app can be used to track the location of your phone in real time or history mode. In history mode, you can see how far your phone has travelled and when it stopped moving for a certain amount of time.
