1. Check whether the compass function is turned on. Go to the "Program List" on the watch, and then select the "Compass" program to try to turn on the compass function.
2. Check the position information of the watch. Enter the "Settings" interface on the watch, and then select "Location" to ensure that the location service is turned on and the location information is accurate.
3. Check whether there is magnetic field interference around the watch. If there is a strong magnetic field around the watch, it may affect the accuracy of the compass function.
4. Try to recalibrate the compass. Enter the "Settings" interface on the watch, find the "Calibrate Compass" option, and then follow the prompts to calibrate.
If the above steps can't solve the problem, I suggest you contact Samsung customer service or go to the official customer service center for consultation and maintenance.
