404+ is a Glyph Matrix controller for compatible Nothing phones — built for people who want more from the back of their device than a static logo.

Hardware that reads, reacts, and lights up.

404+ turns your LED matrix into context-aware glow: pick an animation, register as an official Glyph Toy, and let your phone’s back panel respond to what you’re actually doing.

━━━ GLYPH MATRIX MAXXING ━━━
• 47+ animations across Tech, Organic, Weather, Arcade, ASCII, System, and Utility
• Pixel-perfect preview matched to your device — 25×25 or 13×13 LED grid
• Master speed, brightness, and saver mode controls
• Audio-reactive visuals that respond to music on-device (optional mic permission)

━━━ OFFICIAL GLYPH TOY ━━━
• Register 404+ in Nothing OS Glyph Toy settings
• Output runs on the physical matrix when your toy is selected
• Always-On Display support — keep animations alive on AOD
• Built on the Nothing Glyph Developer Kit — respects system toy binding

━━━ CONTEXT-AWARE AUTOMATOR ━━━
Your back panel shouldn’t need a manual every time life changes. The Automator switches animations by context:
• Charging & battery level
• Incoming calls
• Media playback
• Shake events
• Custom default fallback

Set your rules once. The right glow follows.

━━━ CREATE YOUR OWN ━━━
• Canvas — draw directly on the LED grid with undo, redo, and fill
• Text Marquee — scroll custom text across the matrix

━━━ SUPPORTED DEVICES ━━━
Nothing Phone (3) and Nothing Phone (4a) Pro with Glyph Matrix support.

━━━ OPTIONAL PERMISSIONS ━━━
Microphone, phone state, and notification access power specific automator and audio-reactive features. All optional — deny any permission and the rest of the app still works. Audio is processed on-device and never uploaded.
