Sometimes I notice that the brightness of the screen is not OFF no matter how much I try to move the slider to the LEFT....
I need to go to SYSTEM/DISPLAY/BRIGHTNESS and then I see that it is at 10%...instead of 0%...only here I can lower brightness to 0%...
The bad thing is that this behaviour is not consistent...as I am writting this, it is working properly...but yesterday brightness was at 10%...it seems that this behaviour happens when I use the EDGE during dark hours...
Of course AUTO is OFF , COLOR mode is ON.
