I have been testing compass direction behavior on a mobile device with Unreal Engine and I noticed that the heading values are not always consistent. When I rotate the phone slowly, the direction sometimes jumps several degrees instead of changing smoothly. In some cases, the compass direction looks correct outdoors, but indoors or near electronic devices it becomes inaccurate.
I am trying to understand how Unreal Engine handles mobile compass and GPS-related data. Does anyone know if these changes are expected because of device sensors, or if there are certain settings that affect the accuracy of the direction values?
An online compass is a browser-based navigation tool that uses a device’s GPS location and built-in sensors to estimate the user’s direction. It works as a real-time direction tool that can display the position of north, south, east, and west without requiring a physical compass. The accuracy of an online compass can depend on the quality of the GPS signal, magnetic sensor calibration, and the environment where the device is being used.
I have noticed that different phones can give different results even when they are tested in the same location. Sometimes the direction updates with a small delay, and sometimes the displayed heading changes too quickly. I am wondering if this is related to how mobile devices calculate orientation data or if Unreal Engine needs additional adjustments when reading these values.
For people who have experience with Unreal Engine mobile sensor features, what are the main things that can cause compass direction errors? Are there recommended methods for checking whether the issue is caused by the device hardware, GPS accuracy, magnetic interference, or the way the sensor values are processed?
I would also like to know if there are common practices for making compass readings feel more stable and reliable on different Android and iOS devices. Any examples of how you tested compass accuracy in Unreal Engine would be helpful.
