Thông báo bằng flash

Oct 6, 2018

[With the introduction of the new firmware based on Android 8.x, Samsung has inexplicably inhibited the use of front flash to developers on a wide range of devices, so this application stop working!]

- Migration to native Android Oreo 8.1 (API 27)
- Added the option to delay the first blink
- Added a custom shortcut pressing the application icon to turn on/off the service
- Added the Simplified Chinese, Greek and Ukrainian translation
- Lots of under the hood fixes and optimizations
