## Inferred data model

The phone app owns almost no data: call history is the system `CallLog`, people are the system `ContactsContract`, voicemail number comes from the SIM.

```
CallEntry   (system CallLog) number, name, type (incoming|outgoing|missed|rejected|blocked|voicemail), date, duration, numberLabel
            confidence: high
Contact     (system Contacts) id, lookupKey, name, photoUri, starred, phones[label, number]
            confidence: high
QuickReply  own: id, text, position (default set, editable)          confidence: high
Settings    own: theme                                                confidence: high
```

## Feature matrix

See `features.csv`.

## Out of scope

- Spam detection, caller ID from Google's database, "Non-Spam/Spam" filters: Google service.
- Call screening, hold for me, direct my call, call recording, live translation (ref-03): Google AI services; recording is also blocked for normal apps since Android 10.
- Visual voicemail transcription: carrier/Google service; we only dial voicemail.
- Wi-Fi calling, RTT, video calls: carrier/IMS features the system handles.
- Editing contacts: done by a contacts app; we open it.

## Size

Screens 9, flows 8, entities 2 own. Hard parts: (1) becoming the default dialer and implementing an `InCallService` correctly (call states, audio routing, hold, multiple calls), (2) the incoming call UI over the lock screen with full-screen intent and ringtone handled by the system, (3) fast call log + contacts merging and T9 search. Size: M.
