Changelog
-
v1.1.02026-10-18Latest
- Runtime log now follows the interface language (English / 简体中文 / 繁體中文) — no longer always Simplified Chinese.
-
v1.0.92026-10-17
- Fix: editing carrier name (SIM display name) sometimes did not take effect — save failures no longer falsely report "saved"; read-back verification after write; explicit error + runtime log when not applied.
- Improved: after saving/resetting display name, the actual system name is refreshed automatically.
- Fix: adapted to systems without ISub.setDisplayName (Android 16 / OPPO etc.) — multi-channel reflection fallback (HiddenApiBypass / ISubExt).
-
v1.0.82026-10-16
- New "Personalize" tab: 4 color themes (dark green / ocean blue / warm orange / rose), light & dark modes, custom background image.
- SIM personalization: edit each SIM's display name (status bar card name), one-tap restore to default.
- Trilingual UI: English / Simplified / Traditional Chinese, fully localized.
- Quick presets, country code list & carrier names all follow the app language.
- Language picker on first launch (after Shizuku grant), auto-matches system language, switchable anytime in Personalize tab.
-
v1.0.72026-10-16
- Fix: restored config still showed old overridden carrier name (e.g. 3HK / au by KDDI).
- Carrier name now resolved from real SIM MCC/MNC via Shizuku (46015=China Broadnet, 46002=China Mobile, etc.).
-
v1.0.42026-10-15
- Update check now uses a fast domestic server first (GitHub API as fallback).
-
v1.0.22026-10-15
- Fix: "covered" misjudgment after config restored — now reads the real system state.
- Fix: empty runtime log after errors — all operation errors are now logged.
- New: one-tap copy / export log as file.
- Page auto-refreshes after restore/save, no stale data.
-
v1.0.12026-10-15
- One-tap restore much faster: dual SIM in parallel, removed duplicate blocking sync.
- Save/read speed: service instance cache, timeout protection.
- New: force-clear task for stuck operations.
- Interaction polish: page transitions, button press feedback.
