Device: Lenovo K5 Pro L38041 Treble-enabled: Yes Support: Arm64 a Vendor: stock 8.1 / 9.0 vendor LEDs doesnt work in charging.

I have /sys/class/leds :

/sys/class/leds

init.rc contains:

Turning on / off LED indicator manually works:

echo 255 > /sys/class/leds/red/brightness
echo 255 > /sys/class/leds/green/brightness
echo 255 > /sys/class/leds/blue/brightness

echo 0 > /sys/class/leds/red/brightness

Does the led as notification led?

Please give ls -lZ /sys/class/leds/blue/brightness /sys/class/leds/green/brightness /sys/class/leds/red/brightness

Yes, the blue LED only works on notification

Thanks! After installation, I was able to correctly adjust colors using app - Light Flow Legacy: Led Control I noticed that minimum brightness level is higher than it used to be. Maximum brightness level reaches already at 40% adjustment.
