If the mobile phone compass fails to work, it is recommended that you:
1. Confirm whether mobile GPS satellite positioning is enabled;
2. Whether there is strong magnetic field interference at the location. For example, the use of protective sleeves, protective shells and dustproof plugs made of metal materials will have a certain impact on positioning;
3. Enter Mobile Settings - Apps- App Management - Compass - Clear Data - Clear All Data;
4. If the problem still persists, it is recommend that you apply for after-sales testing.
