I have to manual adjust BACKLIGHT after screen dimming for a minute

sorry, I’m new to this…

Where in sys.py do I put those new lines of code?

This was fixed and merged in.
What version of the launcher are you on?

version 1.2.1.

Ive run the update, I guess thats the most up to date.

Ok, this bug is no longer present in that version.
The brightness will reset when you restart the device, though. But previously it would dim if the device was left in performance mode.

can you see that there are new “power options” in settings after update ?. .
