Q：The compass is shaking.
A：1. A compass requires a clean magnetic field environment. Please ensure your environment is free from strong magnetic field interference. Before each use, draw an 8-shaped calibration diagram, drawing it as many times as possible to ensure its reliability.
2. This compass app incorporates advanced optimization and compensation algorithms, greatly improving its stability. However, many third-party compass apps on the market exhibit varying degrees of jitter due to algorithm limitations. It is recommended to use a compass app with a high number of positive reviews and a high approval rating.
