The Xiaomi Mi 4i comes with the feature-rich MIUI Browser, now with new flatter looks. It does a great job browsing, it syncs with your Google account and supports downloads, there is a night mode, too. It is as almost fast as Chrome, but does not support Find on Page.
On the positive side, it has a built-in Reading mode, which isn't available in Chrome. It enlarges the text font and strips away unneeded elements, leaving only the article you are reading in focus.
The aforementioned Night Mode, which is something we really miss in Chrome. It inverts the background and font colors and is easier on the eyes at dark rooms.
Unfortunately, the MIUI Browser, even though updated, still had issues with some pages and our battery-test browsing script. That's why we suggest you install Chrome, at least as a backup, just in case you need to avoid crashes or you need to find something on a page. Plus it can sync with your Google account easily.
The Xiaomi Mi 4i offers a great file managing app called Explorer, which lets you browse the files in its internal storage and groups them by type.
The MIUI v6 also offers a Security app. It can scan your phone for malware, manage your blocklist, manage or restrict your data usage, configure battery behavior, clean some RAM, it can also manage the permissions of your installed apps.
The custom and now flat Calendar looks good, syncs with your accounts including Google, and offers Day and Month views.
Xiaomi Mi 4i features the WPS Office suite, which supports creating, viewing and editing office files (docs, xls, ppt).
There are also the standard sound recorder, notes, flashlight, calculator, clock, and weather apps, among others, that are a given in any self-respecting Android package nowadays.
We really liked the new Compass app. It has very nice and clean interface, shows the directions and doubles as level. If you lift the phone up then you'll get a nice augmented reality view with real-time directions.
Once again, if Google Maps, Drive, or any other Google-related app isn't installed on your unit, you can get it for free from the Play Store.
