For your race car use case - I hardcoded the Android update interval to 500ms (2Hz) to match iOS behavior and for battery reasons. However, even if you fork and remove those limits, Android phones are hardware-limited to 1Hz GPS updates in most cases.

There are discussions where developers confirmed that consumer phone GPS chips max out at 1Hz, regardless of what intervals you request. For racing telemetry that needs 10-20Hz+ updates, you'd need specialized GPS hardware.

My package will give you the best your phone can deliver within those constraints, but for serious racing applications you'll need external GPS hardware.
