Screen brightness set

An action block that sets the screen brightness settings.

The fiber will proceed immediately without pause.

Since Android 15 and possibly lower on some devices this block may not set a correct brightness level due an Android bug. A workaround is to use the System setting set block with category System, name Screen brightness and a unnormalized level value, that due to the bug may not be between 0 and 255 as documented.

Note! The adjustment value isn’t officially supported, may not work on all devices.

Input arguments

• Automatic — whether screen brightness should be automatically adjusted.
• Brightness — screen brightness in percent.
• Scale — screen brightness scale, use Logarithmic to match the Android 9 brightness slider, default is Linear.
• Adjustment — automatic adjustment limit in signed percent (-100—100%). (Android 4.1+)
