How To Enable Dark Mode on Google App Android 2020
On many Android devices, Google Assistant should follow your system-wide dark mode preferences by default. If your device doesn’t support a system dark mode, you can also toggle it manually or let it adapt based on your device’s battery saver mode. The Discover page found on the left-hand side of many Android devices’ home screens should abide by your system light/dark preferences regardless of your Google Assistant app settings.
In any event, here’s how to manually enable dark mode in Google Assistant.
1. Open the Google Assistant app.
2. Tap the More button with three dots on the bottom right.
3. Tap Settings.
4. Then select General.
5. Scroll down, and tap Theme.
Depending on the device, select Dark, System Default, or Set by Battery Saver.
