This is a personalized compass utility tool, which can set the type of pointer according to personal preference, set the background color, and hide the display of off-angle. The red arrow of the compass points north, the white arrow points south, N on the dial is north, and S is south. When the red arrow of the pointer coincides with the red mark N on the dial, the phone points north. Try to keep the phone level when using it. If the pointer fluctuates greatly, please shake the phone in a figure of eight. If the deviation angle of the display is not required, you can cancel the display in the setting interface to make the interface more concise.
