Night light gets disabled for a moment when set to be on from 00:00 to 23:59
I prefer to manually activate night light, so I set it to be active from 00:00 to 23:59 and manually deactivate it if needed.
The first nights using it under this modality I noticed that suddenly the screen went warmer at exactly 00:00. Later I realized that night light has been off for a moment and that was why I was seeing that sudden transition. Tonight, at 23:57, I noticed that night light was off. I manually disabled and enabled it to no avail. After 00:00 I disabled and successfully re-enabled it. Notice that the problem is not happening only during the last minute, as could be suggested by the gap between 23:59 and 00:00.
There are two different issues mixed here:
-
The first is about usability. There should be a more sensible way of manually toggling night light than setting a 00:00-23:59 or equivalent range. Also, it's not clear that the range is covering the entire day or missing the last minute.
-
The second one is the bug described above.
The subject of report #140 (closed) might suggest it is a duplicate of this one, but the description seems different to me. According to it night light "doesn't work" while here it's a tiny lapse of time after which it resumes working.
