Rosmi worked on enhancing the rdkcentral/rdk-halif-device_settings repository by updating the documentation for the dsSetSecondaryLanguage API. Focusing on API development and documentation, Rosmi clarified the language selection logic to specify that the primary language takes precedence, and the secondary language is used only if configured and the primary is unavailable. This update, implemented in C, aimed to improve developer understanding and reduce configuration errors in downstream integrations. The work addressed a common source of misconfiguration by providing clearer guidance, but was limited in scope to documentation rather than code changes, reflecting a focused but shallow technical contribution for the period.
