Enable Dark Mode in Mi Browser auf Xiaomi
Mi Browser has its own dark theme switch, separate from the general display settings on your Xiaomi phone. Turning on system-wide dark mode in Android does not always carry over to the browser, which is why pages can still look bright even after you have dimmed everything else.
The toggle sits inside your profile menu in the app itself. Open Tap on Mi Browser ➔ Tap on Profile ➔ Enable or disable Dark mode to switch the theme on or off.
Once active, the browser interface, menus, and many supported websites switch to a darker color palette. Not every website respects this setting, since some pages ignore dark theme requests and keep their own fixed colors regardless of what you choose here.
If you want every app on your phone to switch color themes together, use the system-wide dark mode in your display settings instead. That option changes the whole interface at once, while the Mi Browser toggle only affects browsing.
Switch it back off the same way if pages look too dark to read comfortably during the day.
