open android terminal emulator and type these command

su
sh /sdcard/leds-test

It would be helpful to many people as its not a hardware limitations and I trust XDA _/\_"

Looks like (MiuiPro unofficial?) kernel support for color led is coming to Redmi 4X.
Dunno if it works at all in MiuiPro 7.9.14 rom. But I will try to use that boot.img for RR.

Cheers

The "REAL" solution is coming closer.

http://4pda.ru/forum/index.php?showtopic=841683&st=0#entry64978644

Two lib (Redmi 3S Light Module lights.msm8937.so 32/64bit) files need updating.
But still not all colors.
Dunno where these lib files came from (which ROM) but still not perfect.
The fact that owner need to be system is strange.

Beware that your /etc/init.qcom.post_boot.sh and /etc/device_features/santoni.xml
are overwritten by some zip files from 4pda. Better look into the zip file first.

Cheers

This is funny, testing the script does work for the colors cyan, purple, yellow and white.
Not for red, green and blue. They will show up as white!
I'm on LOS14.1.
(edit: it's still better than only 'black or white' )
(edit 2: I also noticed any value higher than 0 will be 'on', so 1 will be just as bright as 90 or 255 and no half brightness for 128)
