We're seeing odometer distance spikes on Android in production.
Actual routes of ~100–200 km are reporting odometer values in the thousands of km — one journey reported 9,397 km on a ~195 km drive. Attached are the map views of the recorded routes; the GPS trail itself is correct, only the odometer is wrong.
Looking at consecutive onLocation events, the odometer jumps forward by 5+ km thousands of times and goes negative an almost equal number of times, so it seems to oscillate rather than drift. Affected devices are realme RMX5250, realme RMX3842, samsung SM-M127G, iQOO I2126 and OnePlus CPH2793 (Android 13–16) — all manufacturers with aggressive background process management.
Our config:
{
reset: true,
geolocation: {
desiredAccuracy: DesiredAccuracy.High,
distanceFilter: 10,
stopTimeout: 1,
stationaryRadius: 15,
filter: {
policy: LocationFilterPolicy.Conservative,
useKalman: true,
kalmanProfile: KalmanProfile.Conservative,
trackingAccuracyThreshold: 50,
odometerAccuracyThreshold: 40,
maxImpliedSpeed: 40,
},
},
persistence: { persistMode: PersistMode.Location },
app: {
stopOnTerminate: false,
startOnBoot: true,
enableHeadless: true,
},
http: {
autoSync: true,
batchSync: true,
maxBatchSize: 50,
},
}
Start sequence is start() → changePace(true) → resetOdometer().
Can you help identify what would cause this? Happy to share raw event logs.
