Core Viewpoint - The article emphasizes the need for a more efficient and integrated mobile experience, particularly through the use of the "negative one screen" feature, which aims to simplify user interactions with multiple apps and services [2][7][28]. Group 1: Current Mobile App Landscape - The average user has installed around 70 apps as of March 2024, with usage frequency reaching nearly 2500 times per month, translating to over 80 interactions daily [5][6]. - The increasing number of apps leads to fragmented user experiences, requiring users to switch between multiple applications for simple tasks, resulting in a "distributed efficiency" problem [6][9]. Group 2: Challenges with Current Solutions - The negative one screen has been underutilized, often becoming a "display area" rather than a functional service hub, leading to user frustration and inefficiency [24][23]. - Users face challenges with information overload, poor navigation, and the need to return to original apps for completing tasks, which diminishes the effectiveness of the negative one screen [24][9]. Group 3: Proposed Solutions with Huawei's HarmonyOS 5 - Huawei's HarmonyOS 5 aims to redefine the negative one screen by transforming it into a service center that provides timely and relevant information without requiring users to navigate through multiple apps [11][25]. - The introduction of "meta services" allows for lightweight, on-demand access to functionalities without the need for installation, enhancing user experience across devices [25][27]. - The new design philosophy focuses on user control, allowing for customizable layouts and minimizing distractions, thereby improving the overall interface and interaction quality [27][28]. Group 4: User Experience Enhancements - The negative one screen in HarmonyOS 5 allows users to view real-time updates on travel, health, and other services, streamlining daily tasks and reducing the need for app switching [12][16][22]. - Users can easily access frequently used tools and services, such as payment codes and travel information, enhancing convenience and efficiency in daily activities [19][21][15]. Group 5: Conclusion - The article concludes that the evolution of the negative one screen into a more intelligent and user-friendly interface represents a significant step towards a more seamless digital lifestyle, where essential services are readily accessible with minimal effort [28][29].
