Automatic Night Mode Schedule auf OnePlus
Night mode on OnePlus phones warms up the display colors to reduce eye strain in low light. Left on manual, it only activates when you remember to tap the toggle, which is why many users see it either running during the day or missing at night.
A schedule fixes that by handing control to the system. You get two trigger options: a rule that follows local sunset and sunrise times, or a custom time range you set yourself. The sunset-to-sunrise rule adjusts automatically as days get longer or shorter, while a custom range stays fixed no matter the season.
To set it up, open Settings ➔ Display ➔ Night mode ➔ Turn on automatically. From there choose either Automatically enable from sunset to sunrise or Custom time range and enter your preferred start and end times.
Once a schedule is active, the manual toggle still works for quick overrides, but it reverts to the schedule at the next trigger point. If Night mode does not switch as expected, check that the correct rule is still selected and that your device location or time zone is accurate, since the sunset-to-sunrise rule depends on both.
