WhatsApp, one of the world's most popular messaging apps, is constantly evolving to meet the needs of its diverse user base. To enhance the user experience and promote multilingual communication, I conducted a thorough user research on the challenges faced by users and I aimed to gain a deep understanding of their global user base's language preferences and needs when communicating in group chats and did a case study introducing a Preferred Language feature. This feature allows users to select their preferred language for the app's interface, making it more accessible and intuitive. In the case study, I outlined the process of designing the Preferred Language feature on WhatsApp, focusing on the user-centric approach that will guide its development.

During usability testing the new design feature proved to be a game-changer in promoting inclusivity, cultural exchange and enabling effective communication for WhatsApp users. During the design process I recognized that users may need to switch languages on the go, especially in multilingual environments or while communicating with friends who speak different languages. I incorporated a dynamic language switching feature, allowing users to change the app's language within the chat interface. This feature enables users to seamlessly switch between languages without navigating back to the settings menu.

Throughout the design process, I actively sought user feedback on the Preferred Language feature. I released prototypes of the app to a selected group of users with a diverse background and encouraged them to provide feedback on the usability and effectiveness of the feature. This feedback was crucial in identifying any issues or areas for improvement. I iterated on the feature based on user feedback, making necessary adjustments to enhance the user experience further.

Designing the Preferred Language feature on WhatsApp involved a user-centric approach, starting with comprehensive user research and incorporating localization efforts to accommodate diverse language preferences. By providing language selection options, dynamic language switching, and actively seeking user feedback, I prioritized the needs of WhatsApp's global user base. The Preferred Language feature exemplifies how user-centric design can enhance inclusivity and improve the overall messaging experience for millions of WhatsApp users worldwide.
