S24 Ultra One UI 6.1.1 Dark Mode

[RuiAlves66]

Since last update on my S24 Ultra, One UI 6.1.1, dark mode setting is not working with custom schedule. It is set to change to dark mode at 7pm, and it works, but to change to light mode at 07am doesn't work. Already clear the cache, stoped to have the phone charging at that time, tried to change the hour for changing the dark mode, nothing is working. This situation started to occur after the 6.1.1 update and even after the latest one this week with the September security patch still doesn't work. Any possible solution someone might know? Appreciate your comments.

Press and hold the Power and Volume down buttons simultaneously for more than 7 seconds

When your phone resets, you will feel it vibrate 
A soft reset can be useful for fixing simple problems

Nope. Already did it...

Solution found: when the phone's battery is in Power Saving mode, it does not allow Dark Mode to turn off automatically as scheduled. Just needed to switch off the Power Saving mode and now it's working!
