However, since using the compass function of my mobile phone, I will never get lost again. However, some friends still don’t understand how to use the compass function. Let me tell you now!

1. First you open the compass software on your mobile phone, such as androits compass!

2. Shake the phone vigorously every time after opening it! Calibrate your compass like this! As shown in the figure, true south and true north are accurate after calibration.

　　
Shake your phone

3. Of course, after calibration, you must hold or place the phone on a horizontal surface to ensure accuracy.

Isn't it very simple? I believe that those friends who complain that the compass function is too bad either forget to shake the phone or do not hold the phone level. Only by doing these two things can the compass work properly.
