This guide explains how language is chosen, how to fix wrong or unwanted languages on the band, how region affects units and formats, and how to avoid common problems after changing language or country settings on an Android device.

How Language and Region Work Together
There are three main layers that influence what you see on Xiaomi Mi Smart Band 4:
-
Android system
Controls the primary language of the phone interface, regional preferences such as date format, and basic locale (country/region). -
Mi Fit application on Android
Reads the system language and region, then decides which language pack and formats to push to the band.
Some versions let you explicitly choose units (metric or imperial) and time format. -
Xiaomi Mi Smart Band 4
Displays menus, workouts, notifications and data using the language and formats provided by Mi Fit.
Most of the time, you change language or region once on the Android phone and everything else falls into place after a short sync.
-
Band Language vs Phone Language
By design, Xiaomi Mi Smart Band 4 usually follows the phone language:
-
If Android is set to English, the band shows menus in English.
-
If Android is set to another supported language, the band switches to that language after syncing.
Key points:
-
The band does not have a separate, fully independent language menu like a smartphone; it relies heavily on what Mi Fit and the Android system tell it.
-
Some language changes take effect only after Mi Fit reconnects to the band and pushes the updated settings or firmware resources.
-
If a language is unsupported on the band, it may fall back to English or another default, even if the phone uses a different language.
-
Changing Band Language via Android System Settings
The most common and reliable way to change Xiaomi Mi Smart Band 4 language is to change the primary language of your Android phone, then let Mi Fit sync the new setting.
Typical steps on Android (exact menu names vary by device):
-
Open the system settings of the Android phone.
-
Go to the language and input section (for example, “Language & input” or “System > Languages & input”).
-
Change the device language to the desired option, such as English.
-
Once the phone language is updated, open Mi Fit.
-
Make sure Xiaomi Mi Smart Band 4 is connected and close to the phone.
-
Wait a moment for the band to sync; in many cases it will update its language automatically.
If the language does not change immediately, try:
-
Closing and reopening Mi Fit.
-
Turning Bluetooth off and on.
-
Restarting the band or the phone, then reconnecting.
-
Language Selection from Inside Mi Fit (When Available)
Depending on Mi Fit version and firmware, some users may see a language-related option directly inside the band’s settings:
-
Open Mi Fit on Android.
-
Go to the Profile tab.
-
Select Xiaomi Mi Smart Band 4 from the list of devices.
-
Look through the settings for an item related to language or region.
If such an option is present, it lets you pick from a list of supported band languages independent of the phone’s system language. If it is not present, language will strictly follow the Android system language as described earlier.
In either case, after adjusting language options, keep the band near the phone for a few seconds so Mi Fit can push any changes.
-
Fixing the “Band Shows Chinese” Problem

A common situation with Xiaomi Mi Smart Band 4 is that it may show Chinese characters right after unboxing or after a reset, especially in some regional versions.
To fix this and switch to English (or another language):
-
Make sure the Android phone is set to English as the system language.
-
Install and open Mi Fit on Android.
-
Log in with a Mi account and add Xiaomi Mi Smart Band 4 as a new device.
-
Allow the band to pair and update; in many cases, the band will automatically download a global firmware and switch to English after syncing.
If the band still shows Chinese text:
-
Ensure that Mi Fit is updated to a recent version.
-
Keep the band connected for several minutes; firmware and resource updates can take some time.
-
Restart the band after the update completes.
Once the global firmware and language resources are installed, language changes tend to follow the Android system more smoothly.
-
Region, Units and Time Format

Region settings affect more than just language. For Xiaomi Mi Smart Band 4, the important region-related aspects are:
-
Distance units: kilometres vs miles
-
Weight units: kilograms vs pounds (used for profile and calorie calculations)
-
Temperature units: Celsius vs Fahrenheit (for weather on the band, if enabled)
-
Time format: 24-hour vs 12-hour clock
-
Date format: the order of day, month and year
These settings are typically configured in two places:
-
Android system region and language
-
Mi Fit app settings on Android
Inside Mi Fit, you may find options like:
-
Units: choose metric (km, kg, Celsius) or imperial (miles, lb, Fahrenheit).
-
Time format: sometimes selectable; otherwise it may follow the phone’s 24-hour or 12-hour setting.
After making changes, sync the band so that Xiaomi Mi Smart Band 4 displays the new units and formats consistently across screens.
-
Weather and Location Region Settings
If weather is enabled on Xiaomi Mi Smart Band 4, region also plays a role in:
-
Which city is used for the weather forecast.
-
Temperature units (Celsius or Fahrenheit).
-
Possibly the language of weather descriptions, depending on how Mi Fit is configured.
To adjust weather settings:
-
Open Mi Fit on the Android phone.
-
Go to the Profile tab and select Xiaomi Mi Smart Band 4.
-
Look for Weather settings.
-
Set your city or choose “current location” if available and permitted by Android.
-
Ensure units (Celsius vs Fahrenheit) match your preference in the app’s unit settings.
Once synced, the band will show forecasts in the chosen unit and for the selected location, aligned with your regional preferences.
-
Multilingual Notifications and Character Display
Xiaomi Mi Smart Band 4 can display notifications from multiple languages based on the phone’s input and the app sending the message. However, display quality depends on available fonts in the band’s firmware.
Typical behaviour:
-
Latin-based alphabets (English, many European languages) generally display correctly.
-
Some special characters, accented letters or scripts like Arabic, Cyrillic or others may show partially, depending on firmware version and font support.
-
If a character is unsupported, it may appear as a square or a placeholder symbol on the band.
What helps:
-
Using a global firmware version that supports more languages.
-
Keeping Mi Fit and the band’s firmware updated.
-
Ensuring the phone’s language and Mi Fit region are set to a combination that the band supports well.
Even when some characters do not show perfectly, basic notification content is usually still understandable, especially if the main language uses supported scripts.
-
Behaviour After Changing Language or Region
After changing language or region on the Android phone or inside Mi Fit:
-
Mi Fit may restart or briefly reconnect to Xiaomi Mi Smart Band 4.
-
The band could receive new language resources or unit settings.
-
During updates, the band might show reboot screens or update progress bars.
If something looks strange (for example, wrong units, mismatched date format, or partially updated language):
-
Confirm the new system language and region on Android.
-
Open Mi Fit and leave it running for a short time with the band nearby.
-
Trigger a manual sync by swiping down on the band’s device screen in Mi Fit (if supported).
-
Restart the band if necessary from its Settings menu.
Typically, after this sequence, all menus, units and formats align with the new language and region.
-
Common Problems and Simple Fixes
Problem: Band language does not change after phone language update
-
Make sure Mi Fit is open and the band is connected.
-
Force a sync by refreshing the device page in Mi Fit.
-
Restart Bluetooth or reboot the phone.
-
Update Mi Fit to the latest version.
Problem: Units on band do not match units in app
-
Check unit settings inside Mi Fit (metric vs imperial).
-
Toggle the unit setting, sync the band, then toggle it back if needed.
-
Ensure that Android itself is using a compatible region (for example, a country that typically uses metric or imperial units, depending on your choice).
Problem: Date format and time format look wrong
-
Adjust 12-hour vs 24-hour format in Android system time settings.
-
Ensure the phone’s region matches your expectations for date order (day/month/year vs month/day/year).
-
Open Mi Fit and resync; the band usually follows what the phone uses.
Problem: Mixed languages on the band (some menus in one language, some in another)
-
This can occur right after updates.
-
Restart Xiaomi Mi Smart Band 4 from its Settings.
-
Keep the band connected to Mi Fit for a while to complete any resource updates.
-
Best Practices for Stable Language and Region Settings
To avoid confusion and keep Xiaomi Mi Smart Band 4 consistent:
-
Decide on a primary language and region for your Android phone and keep it stable.
-
Use Mi Fit on Android as your main place to adjust units, time format and weather preferences.
-
After any important change, give the band time to sync and update before assuming something is broken.
-
Avoid frequently switching between very different language-region combinations unless necessary; repeated changes can sometimes cause temporary display quirks.
-
Keep Mi Fit and the band’s firmware updated so you get the latest language packs and character support.
With a clear understanding of how Android, Mi Fit and Xiaomi Mi Smart Band 4 share language and region information, it becomes easy to control how your data looks on the small screen: in the right language, with the right units and in a format that matches the way you read time, dates and weather every day.
