---

## [1.0.4] - 2026-10-09
### Full Per-Device Data Isolation Architecture
- Physical per-phone directory structure inside mobilenetworks/cellphones/<imei>/:
  - Gallery and Photos: Each physical device maintains its own photo album without bleed or cross-contamination when swapping phones.
  - Gram Social Network: Sessions, accounts, and profiles are fully partitioned by device folder. Switching devices immediately switches active Gram account.
  - SMS & Chat History: Server message threads and texts are bound to the specific device identifier.
  - Notification Log: In-game notifications and history are stored individually per device.
  - Per-Phone App State: Installed and uninstalled app preferences persist per physical device.

### SIM System & Call Integration
- Simple Voice Chat and CallEngine call routing:
  - Phone calls are processed through the active SIM card's unique phone number.
  - Realistic privacy: Borrowing another player's phone dials using their inserted SIM number, without exposing the caller's real username.
  - Dual SIM support: Craftable SIM cards, secondary slot support, and in-settings primary line switching.
  - Quick-copy pill button on the call screen to copy phone numbers directly to clipboard.

### Unlocked App Store & Modder Engine
- Store unlock and custom application support:
  - Community JSON app loading via mobilenetworks/apps/*.json.
  - Native uninstallation support for all Store apps (including Gram, Maps, and Speedtest).
  - Built-in Calculator application featuring arithmetic engine, percentages, and history log.
  - Built-in Snake Classic retro arcade game.
  - Refined app icon visuals adhering to the minimalist style of Mobile Networks.
  - Expanded public developer API (MineStoreAPI) providing device info (DeviceInfo), hardware/SIM status queries, per-phone isolated app data persistence (saveAppData/loadAppData), and toast notification triggers.

### Mine UI Settings
- Modern settings interface:
  - Dynamic wallpapers and local gallery wallpaper picker.
  - 12-hour and 24-hour clock formatting.
  - Ringtone/sound toggles and notification detail preview switch.
  - Dual SIM slot management (eject, insert, switch active slot).
  - Cleaned up settings structure to prioritize hardware-level SIM identity.
