Hi all,

There are a number of apps on the Android App Store that enable you to lower the minimum backlight brightness (or claim to), but I'm looking for de-Googled FOSS options.

Any suggestions? Thanks

I'm driving the latest GrapheneOS and don't see it. I don't think they actively remove that option, but I might be wrong. Where are you seeing it, and are you sure it's not your OS that implemented it instead of upstream AOSP?

    I'm on graphene and see it. Your device may not support HDR.

    I'm on a Pixel 9a running Graphene and it's not an option on mine, it's probably not an option on the Pixel tablet either but I'm not at home to check. I'm guessing you've got a 10 series?

    It's this setting: https://github.com/aosp-mirror/platform_frameworks_base/blob/1cdfff555f4a21f71ccc978290e2e212e2f8b168/packages/SettingsProvider/src/android/provider/settings/backup/SecureSettings.java#L68. You can trace it in the source code. The general name is Reduce Bright Colors. Check Graphene's src for that. Woulda linked Google's AOSP web page but it's giving me 503 because that's how Google do these days.
