Erratic Ambient display / LiveDisplay on Samsung S10e

Hi there,
I use Ambient display and LiveDisplay on my S10e, mostly to prevent blue light. Hence my screen colours are supposed to have a red shift.
They do when I activate the option in dedicated menu.
But then they don’t after the screen went black… Basically, to get it work again, I can:

  • go to the dedicated menu again and re-enable it
  • switch to Airplane mode or turn battery saver on (??)

In any case, as my screen turns off many many times a day, this makes the LiveDisplay functionality a hassle in daily use.
I suppose this is a software bug (maybe upstream?). Any chance to get that fixed?
