LED Me Know addresses a specific gap in modern smartphone functionality by recreating the traditional notification LED experience through software-based animations on Samsung devices with Always-On Display support. Developed by Anker Technologies, this application specifically targets users who miss the visual notification cues that were commonplace on earlier Android devices before manufacturers began removing physical LED indicators. The application's core functionality revolves around displaying customizable animations when notifications arrive. Users can select from multiple animation styles including icon displays, glow effects, spinning animations, and notch-based indicators. The system allows configuration to show either only the latest notification or cycle through all pending alerts. Additional customization options include precise timing controls for LED duration, adjustable size and positioning of the animation display, and specialized charging indicator modifications. The application requires Android 11 or higher and specifically functions with Samsung's Always-On Display technology, making it compatible with recent flagship models including the S22 series. User experience centers around the straightforward configuration interface that organizes settings into logical categories. The animation preview function allows real-time testing of different effects before implementation. In practical usage scenarios, the application operates seamlessly alongside native notification systems without requiring excessive battery consumption, though performance may vary depending on device-specific Always-On Display implementations. The customization depth enables users to create distinct visual cues for different applications, making it possible to identify notification sources without activating the device's screen. No user reviews are currently available for detailed analysis of real-world implementation experiences. The absence of user feedback makes it challenging to assess potential issues or exceptional performance aspects that might emerge during extended usage periods across different device models and usage patterns. The application's primary strength lies in its focused approach to restoring a valued functionality that manufacturers have removed from modern devices. However, limitations include its exclusive compatibility with Samsung devices featuring Always-On Display technology and specific Android versions. The app serves users seeking visual notification indicators without constantly waking their device's full display, particularly those transitioning from older devices with physical notification LEDs who want to maintain similar functionality on modern hardware.
