I have a Moto G5+ running Oreo 8.1. All my widgets have slowly drifted towards using the dark theme. I vaguely recall once enabling dark theme, but I'm not quite sure, especially since I've read that the theme adjusts itself to your wallpaper.
I dislike the dark theme on a number of widgets, like Keep and Calendar. Is there any way to disable dark theme on those?
Or is the only way to use an app to fake a light wallpaper?
