June 2025 highlights include delivering congestion and pet charges handling in the Mobility App and stabilizing the location heartbeat mechanism. The heartbeat timer in LocationUpdateServiceV2 was fixed to initialize only when absent, eliminating redundant schedulers and simplifying logs (commit 844074ba1827643fb243766866237356fe4a66b9). The Mobility App now displays and processes congestion and pet charges, with updates to the notification utility and overlay sheet service (commit 6a2858c393a835811a46175b2ed1d4b95e210403). These changes reduce battery and CPU churn, improve billing transparency for users, and enhance end-to-end reliability. Logging was refactored to use Android's built-in logging functions for better traceability across location updates and charges UI.
