<![CDATA[Range for manually adjusting brightness]]>Is there any way to manually adjust brightness to an even lower value than the minimum brightness achieved when moving the slider in the top menu to its most left position?

  • maybe from command line?
  • or maybe the minimum that can be achieved by moving the slider can be edited somewhere to be set to an even lower value?

Thank you for any input!

Context: I keep my phone unlocked during the night in order to display the time but the screen backlight bleed bothers me.

Next I'll see if I can modify somewhere the minimum value that the slider can adjust so that I will use the slider in the brightness menu and not the command line.

/sys/devices/platform/soc/c440000.qcom,spmi/spmi-0/spmi0-05/c440000.qcom,spmi:qcom,pm6150l@5:qcom,wled@d800/backlight/backlight/brightness

and minimal value is 161, maximal is 4095

when i set from root to zero, it seems to be just black, that is fine 😄 i shall test minimal value at night

I change its value to let's say 100

100 it's overkill, try 2 or 4. Also check '*brightness*' with the find command.

If I change its value to let's say 100, there's no change on the device's brightness though...

What else could I try?

Thank you!
