Automatically Enabling Dark Mode is Not Working with Android [IONIC 5]

Hi There!

Tried implementing Automated Dark Mode referring this link, https://ionicframework.com/docs/theming/dark-mode#automatically-enable-dark-mode .It worked fine with IOS (13+ and Iphone XR) but while running the same on Android (V10 and OnePlus 7T) I couldn’t see this working (Toggling Logic does works).

Is this a know OS behavior or there is a way to automatically enable this for Android?

Any help is much needed!

Cheers
