Two fresh lock screen clock faces join the customization party, alongside redesigned Nothing app icons and intuitive status bar updates. Smoother transition animations make scrolling and switching feel fluid, elevating the dot-matrix aesthetic Nothing fans adore.
Glyph Interface Evolution

Glyph Progress taps Android 16’s Live Update notifications, expanding support to apps like Spotify, Uber, and Zomato for real-time progress rings on deliveries or tracks. This breathes new life into the Phone (3a’s rear LEDs, turning them into practical notification hubs rather than mere gimmicks. With third-party compatibility surging, Glyph becomes a productivity ally, lighting up rideshares or playlists without screen wakes.
