Dot 137 - Nothing Glyph Matrix

137 LEDs. Yours to control.

Dot 137 turns the circular Glyph Matrix on the back of your Nothing Phone (4a) Pro into a canvas — for scrolling text, pixel art, and silent notification signals you design yourself.

— TEXT —
Type a message and watch it scroll across the matrix as a marquee. Tune the tick interval and scroll step with precise, mechanical controls. What you see in the in-app preview is exactly what the hardware does — the preview mirrors the LED layout dot for dot, tick for tick.

— DRAW —
Tap or drag directly on the 137-dot grid to draw. Every dot in the editor corresponds to a physical LED on the back of your phone. Save your drawing and set it as your Glyph Toy — it stays visible with Always-on Glyph support.

— NOTIFY —
The quiet flagship feature: assign a drawing to any app. When that app sends a notification while your phone is locked, your drawing lights up the Glyph Matrix — and stays lit until you unlock. Phone face down on the desk, you still know exactly who's calling for your attention. A glance, not a grab.

Per-app, fully yours: a heart for your favorite person, a bolt for your bank, anything you can draw on 137 dots.

— DESIGNED LIKE IT BELONGS —
Pure OLED black. Dot-matrix typography. Instrument-style segmented controls. No clutter, no gradients, no noise. Dot 137 is built to feel native to your phone, not bolted on.

— HOW IT WORKS —
• Activate the "Canvas" toy from Settings > Glyph Interface to show your text or drawing
• Set it as your Always-on Glyph Toy to keep it visible on the AOD
• For notification drawings, grant Notification Access when prompted — this is required to detect which app posted a notification. Notification content is never read beyond the app's package name, and nothing leaves your device.
