Yesterday I did a 100km ride with many sharp turns.
I can confirm the observation from @Tom, that in some situations map rotation lags behind reality. Maybe 3 seconds or more. Especially after sharp turns at crossroads with subsequent rapid acceleration.
My settings:
- Kalman filter: on
- Smooth movement: on
- Location service: Google
- Samsung Galaxy S7, Android 8
I switched Kalman filter off → no visible difference.
Then I changed location service from Google to Android.
Remaining test time was to short for a final conclusion, but my impression was, that map rotation was now way faster.
My observation so far, leads me to the conclusion that Google location service lags behind reality.
