Why do widgets show Black background in Light Mode
If the Dumb Phone widgets display a black background when Light Mode is turned on, and/or the Home Screen Customize is set to Default / Light, it's likely the App Launcher's background has been explicitly set to Black.
Change the Background and Text Color to a lighter color
- Open Dumb Phone → Launcher Style
- Under the Background section, select the Light Gray color
You can also alternatively select Auto Dark / Light Gray
- Under the Text section, select the White color
You can also alternatively select Auto Black / White
