The Xiaomi Redmi Pro runs a stable version of the latest MIUI 8, which is built on top of an Android 6.0 core. That's as new as it gets for Xiaomi, which is yet to out a smartphone running Android 7.0 Nougat core.
MIUI 8 doesn't bring a lot of new eye candy to the picture, but comes with better text rendering, enhanced Power saving mode, new Notes app and Enhanced video editing tools.
As usual Xiaomi's customizations run very deep and replace everything including all Google services. In fact, the Mi phones sold in China don't have access to Google's services and those need to be sideloaded one way or the other (some resellers may even do that for you). The models sold officially on markets outside of China come with a preloaded Play Store app.
The lockscreen is unchanged from MIUI7 and has a clock in the top left corner - gone are the lockscreen widgets. To unlock the phone you swipe upwards and if you want a quick access to the camera - just swipe from the right side.
Fingerprint unlock is available and the sensor is built inside the Home button under the screen (a first for the Redmi series). Unlike other Xiaomi phones which have the sensor on the back, this one is not always on and you have to press the button for it to scan your finger and unlock the phone - just like a Samsung phone.
Beyond the lockscreen is the Android homescreen with four customizable shortcuts docked at the bottom by default, but you can dock up to five items. You can have any app there or even folders with multiple items if you will.
There is no app drawer - anything you install pops up on your homescreen, which can have unlimited panes. There're no shortcuts and the usual routine of removing icons (dragging them up to a recycle bin at the top of the screen) will uninstall the corresponding app. There is a pop-up for confirming the action though, so you can't accidentally uninstall apps.
Homescreen widgets are available, too - tap and hold on the homescreen, then choose Widgets. There are few options available, but of course, you can get even more from the Play Store.
Homescreen effects are available and you can change themes, too. A theme will change your homescreen wallpaper, lockscreen style, system icons, system font and the sound profile (you can disable changing the sound profile from settings).
The notification area has two semi-transparent tabs - the first one hosts all notifications, while the second one (swipe left to access) offers customizable quick toggles and a Settings shortcut.
An enhanced task switcher with Clear All option is available, too.
The Do Not Disturb mode has been enhanced too - it supports better customization and scheduling options.
We did get our review unit with pre-installed Google Play Store plus Google sync for app data, contacts, and browser data but perhaps they've been sideloaded by the reseller providing this review unit. Of course, you can sideload them yourself one way or the other if they don't come pre-installed on your unit. And once you have those, you can easily download all other Google apps such as Google Now straight from the Play Store.
