Now Dark Theme is available on Google Play Store
Android 10 has many new features including the Dark Theme feature that’s ideal for low light and help to save battery. Users can activate system-wide dark theme by going to Settings or turning on Battery Saver. This changes the system UI to dark and enables dark theme on apps that support it. You can also opt in for new Force Dark feature that lets the system dynamically creating a dark version from your existing theme.
But this Dark Theme feature was not on Google Play Store until today. On many Pixel smartphones the entire UI showed a dark grey background color.
