Историческую версию Bright Screen Light можно получить на Android
Это очень простое приложение, чтобы показать белую полный экран на максимальной яркости.
This is a very simple app to show a white full screen at maximum brightness. This can be used as an external light source in case of emergency. That's it.
No permission required! No ads!
To avoid accidental launch, the 'keep screen on' option (disable screen timeout) is not turned on by default. The 'keep screen on' option can be toggled under the application's menu.
