Hi, not sure if someone has already made the same suggestion but I would like to see better night light mode with more deeper intensity of nightlight from not noticable yellow coloration (as it is right now) to more visible pure red color of display as it has an iOS for example. Those red tones are used in OLED displays (fairphone has those type of display) for like astronomy or everytime if you just want to sleep better. I would be happy also for only deeper orange tone.
The problem of using 3rd party app like Red moon or Twilight is that its using a lot of battery because the apps just create only a red film over all blue content. OLED can turn off individual black pixel and can work with Red color only, Green and Blue are set to 0 and wont shine with blue background light as LCD. For best experience, this implementation needs to be done on the system side.
I have Fairphone 6 with e/os v3.3 currently
