The compass is installed on the mobile phone.

Compass is a tool to indicate the direction, which can help us determine the direction when we are outdoors. Now, with the popularity of smart phones, we can install a compass application on our mobile phones, making it a necessary tool when we travel.

Install compass application

To use the compass on your mobile phone, you need to search for the compass application in the app store and download and install it. At present, there are many compass applications to choose from in the market, and users can choose different applications according to their own needs. After installation, users are usually asked to calibrate the compass when opening the application. The usual way to calibrate the compass is to rotate the mobile phone several times, then put it on a horizontal plane and wait for the application of automatic calibration.

Use a compass

After installing the compass application, we can use it to determine the direction at any time on our mobile phone. First, you need to make sure the phone is flat, then open the compass application and wait for the compass pointer to stabilize, so that you can see the current direction. When using the compass, you need to pay attention to avoid touching metal objects, because metal objects will interfere with the instructions of the compass.

Precautions for compass

Although the compass can help us determine the direction, we also need to pay attention to some matters when using it. First of all, the indication of the compass will be influenced by the surrounding environment, such as electronic equipment and buildings. Secondly, the compass also needs to be calibrated during use, otherwise there may be indication errors. Finally, the compass can only be used to determine the direction, but not to measure the distance or height.
