Overview

Nothing Dialer 1 is a custom dialer application designed exclusively for Nothing OS — the minimalist, glyph-accented Android skin powering the Nothing Phone series. Where the stock dialer treats the Glyph Interface as a notification-only feature, Nothing Dialer 1 extends it to active, in-progress call states.

When you place or receive a call, the phone's signature LED glyphs light up in choreographed patterns that convey call state — ringing, picked up, on hold, ended — making the back of your Nothing Phone a live, ambient call indicator.

Glyph Patterns

The app integrates with the nothing_glyph_interface to expose individual LED segments that can be addressed programmatically. It allows customizable animation styles right from the settings (e.g. "Breath & Progress", C1-C4 Intervals, and Custom Channels). Nothing Dialer 1 maps call lifecycle events to these animation sequences:

Features

• ▸Glyph-aware dialer — Custom glyph animations for outgoing AND ongoing calls (the stock app only supports incoming).
• ▸Minimal UI — Built in Flutter but heavily adheres to the Nothing OS design language: pure, minimal, and typography-focused.
• ▸Customizable Glyphs — Fine-tune parameters like Breath Progress duration, interval speed, and active LED channels directly in the dialer settings.
• ▸Cross-Sim Support — Picks appropriate SIM and native controls seamlessly.
• ▸Deep Android Integration — Uses Android's TelecomManager and InCallService to completely replace the system dialer workflow.

Technical Details

Nothing Dialer 1 is built as a cross-platform Flutter application, heavily relying on Kotlin Platform Channels for the deep Android integration required by TelecomManager and InCallService. The backend uses the nothing_glyph_interface Dart package (communicating over a MethodChannel) to manage LED sessions and bind animation sequences to call state callbacks broadcasted from the native GlyphInCallService.

// Example: Triggering Glyph lights from Flutter during an active call
void _triggerGlyphLights(String callState) async {
  if (callState == "DIALING") {
    // Start Outgoing call animation (e.g., Breath & Progress)
    await _glyphMethodChannel.invokeMethod('startGlyphAnimation', {
      'style': _glyphAnimationStyle,
      'duration': _glyphBreathProgressDuration,
    });
  } else if (callState == "ACTIVE") {
    // Switch to On-call Custom Channels
    await _glyphMethodChannel.invokeMethod('setCustomChannels', {
      'channels': _inCallCustomChannels,
    });
  }
}

Status

Active development on feature/mobile. Essential dialing, SIM selection, native InCallService integration, and Flutter MethodChannels are implemented. Refining ongoing call glyph synchronizations and the history log interface.
