Let's face it: inside each of us there is an EMO ... Yes, since the dark theme was "invented" we are constantly searching for apps and phones. Although the dark theme is definitely convenient and appreciable in its beauty on AMOLED screens, it is possible to exploit its potential on every Xiaomi smartphone provided it is provided with the MIUI 10 Stable version, waiting for the future MIUI 11 to integrate it by default.
How to enable the dark theme on Xiaomi smartphones

For disable it instead just send this other command:
If you prefer, yes alternate automatically to the clear one like day and night:
Theoretically with the arrival of Android Q and MIUI 11 you can benefit from this mode natively, without having to resort to ADB command lines, but if some devices fall behind with updates, I would say that this is a really simple procedure to be performed for each user. I remember once again that the Dark Theme finds its maximum expression with AMOLED display allowing you to save battery, but the curiosity I know prevails more than anything else, so give us below with the ADB commands and let us know how you are.
