I’ve rooted my device to get an acceptable blue light filter on my phone (1500K), I really don’t like the idea of having to root just for that and play the cat and mouse game to hide the root. Any other way to do it? I’ve looked everywhere and nothing is close to what I want. The default night light in the settings barely goes below something like 2500K and the LiveDisplay feature in lineageOS and Calyx mess up the colors and there is a lot of blue that is not filtered at all. Anything you guys found?

    Twilight app. Ranges from 1000k to 5000k with adjustable intensity and additional screen dim even below typical system minimum.

        I don’t understand the difference. It’s still changing the color of light emitted by your phone, so the distinction doesn’t make sense.

          filter overlays reduce contrast, and wash out colours darker than the filter colour - quick mock-up:

          colour tester image with normal and multiply blend mode orange overlays

          (notice how dark greys and black are actually brighter than without the filter)


          in answer to the original question, op, i’m not sure there is one. i don’t think android allows changing display properties such as temperature without root unfortunately

    I’ve been using twilight for a long time across phones and tablets. I thought you could get hold of it through the aurora store front as I had it on an older pixel with grapheneOS.

    Currently run it on a android 11 tablet and android 13 phone, stock ROMs, unrooted, unmodded.

    If I understand the technical side of things properly, a proper filter (not just an overlay) has to be implemented at the system level, so I think your only options are going to be an overlay, or something that works via low level access like changing ROMs or root access :/

    EMUI from Huawei has an Eye Comfort setting. I assume other brands have an equivalent feature, if you have a preference in term of UI

      They’re actual filters but they just go to about maybe 2500K and I’m looking for as low as 1500K. Something similar to CF.Lumen but without the root.
