Navigation lights are off on Lumia 1520

[DCPaul]

After installing AU on my Lumia 1520 I notice that the navigation lights are always off. Although when phone is restarting all the navigation lights lit up then stays off....so it seems that my lights are working but turned off my OS.... Is there any way I can bring back to normal lit upon touch?

Have you try doing a soft re-set?

do the buttons still work? sometimes, the lights going out is a sign that the daughter board may be on the way out.

I think you have battery saver brightness turned on. This feature turns off the backlight of the capacitive buttons.

Go to Settings > Extras > Display and turn off the "Battery Saver Brightness"
