Worked on the organicmaps/organicmaps repository to enhance the stability and consistency of the Android navigation user interface. Focused on resolving a critical bug related to fullscreen handling during Route From navigation, ensuring that fullscreen mode exits correctly at the start of navigation and matches the behavior of Route To navigation. Utilized Java and Android development skills to deliver a targeted fix that resets the fullscreen state, improving user experience and reducing potential confusion. The solution addressed UI consistency by aligning navigation states across different routes, ultimately streamlining the navigation flow and minimizing the likelihood of user support issues related to fullscreen behavior.
