Settings dark background in Android 8 The upgrade to Android 8 changed the background of the settings and the roll down menus to white. This makes it harder for me to read (partially colourblind); how can I change the background again to black?
Google has added a dark theme to many of dev previews of Android, but they always remove it at the last minute :(

So, unless the OEM skin on your device provides this option, it looks like your only course of action would be to follow XDA's guide on installing a dark theme without root.
