Introducing Lumen 2.0 — a phone OS made of light and glass

Lumen is a complete phone operating system, designed around light and glass, running on an ordinary Samsung Galaxy A12. Underneath, Android 13 keeps the lights on: the drivers, the radios and every app on Google Play. Everything you see is Lumen: the lock screen, home screen, Control Center, Notification Center, keyboard, widgets, Settings and fourteen apps built from scratch. Designed by one person. Built together with AI (Claude).
