Hi Helmut, thanks again for reporting this. We investigated the issue and tested the direction fan around the current location marker separately from the recent compass widget changes.
The recent changes affect how compass direction is updated in widgets, but we could not find any connection between them and the direction fan on the map. The fan is updated from the device's compass/orientation sensor data even while the position and map remain stationary. One setting that can noticeably affect its responsiveness is the **Kalman filter**. OsmAnd uses it to smooth compass readings and reduce small sensor fluctuations, but on some devices this smoothing can also make direction changes appear delayed or sluggish. You can try disabling it here: *Menu → Settings → Configure profile (e.g. Browse map) → General settings → Other → Use Kalman filter → Off* More details about this profile setting are available in the OsmAnd documentation <https://osmand.net/docs/user/personal/profiles/#other>. We also compared OsmAnd with a standalone compass app on a test device. With the Kalman filter disabled, both reacted similarly to rotation and showed only small settling corrections after the device stopped rotating. This suggests that any remaining small delay or correction may come from the device sensors or Android's orientation processing rather than from OsmAnd's map rendering. Could you please try disabling the Kalman filter in the OsmAnd settings and let us know whether the direction fan becomes more responsive? пʼятниця, 21 серпня 2026 р. о 16:25:30 UTC+3 Hobbit пише: > If by "fan" you mean that little blue shadow that swings around the > position marker, I never understood what that was for and it seems to > only vaguely follow the magnetometer orientation (if "sensors" are > enabled, which is a setting in newer android).
