Turn on camera flash LED, tap notification OR THE ICON to turn off.
It needs file read and write permissions to accomplish this. A folder is used to indicate the state of the flashlight, acting like a global variable. However, you may see errors in the log.

The folder used: /sdcard/Automate/ownsFlashlight
The parent folder isn't deleted.
