        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.

          Start from find /sys -name brightness.

            @paulcarroty Allright, I see /sys/devices/platform/soc/4784000.sdhci/leds/mmc0\:\:/brightness and it has the value of 0. 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!

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

                @mihael on mine miatoll it seems to be
                /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

                root@uxesPhone:/home/phablet# echo 1 > /sys/devices/platform/soc/c440000.qcom,spmi/spmi-0/spmi0-05/c440000.qcom,spmi:qcom,pm6150l@5:qcom,wled@d800/backlight/backlight/brightness

                  Thank you both, I found it: echo 10 > /sys/devices/platform/soc/5e00000.qcom,mdss_mdp/backlight/panel0-backlight/brightness - this is how I can manually change the brightness...

                  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.
