Bug Fix                                                                                                                           
                                                                                                                                    
  - Fixed an issue where Chinese text appeared on some screens when the app language was set to English. All UI elements now correctly
   display in the selected language.

### 1.0.1 — 2026-03-01

**Bug Fixes & Performance Improvements**

- **First Launch Fix**: Fixed an issue where WiFi information was not detected during the first diagnosis after a fresh install. The app now properly waits for location permission before proceeding.
- **Diagnosis Speed**: Significantly reduced diagnosis time. Gateway and internet connectivity checks are now 3-5x faster.
- **Speed Test Accuracy**: Completely reworked the speed test engine with multi-connection parallel testing (4 simultaneous connections), matching industry-standard tools like Speedtest by Ookla. Results are now within 10-15% of other speed test apps.
- **Speed Test Reliability**: Fixed a critical issue where download and upload speeds could show 0.0 Mbps. Replaced the HTTP session with a cache-free configuration to ensure accurate measurements every time.
