Integration of wearable electronics from Chinese giant Xiaomi with flagship smartphones of Korean company Samsung usually goes without a hitch, but recently users are faced with a number of software nuances. The main difficulty lies not in the hardware incompatibility of Bluetooth modules, but in the constant changes in the security policy of the Android operating system and aggressive optimization of power consumption by the One UI shell. These factors often prevent the stable operation of the background processes necessary for the transmission of pulse data and notifications.
Owners of Galaxy S or Galaxy A series devices need to understand that the standard "on and off" algorithm doesn't always work predictably here. The system can "sleep" the intermediary application by itself, breaking the connection to the activity tracker. So the right initial setup is critical for the long-term stability of the gadget, and we will analyze all the steps from choosing the right software to fine-tuning the system resolutions.
Modern bracelet models, such as the Mi Smart Band 7, 8 or 9, require the use of current versions of mobile applications, as support for old software gradually stops. If you try to use an outdated Mi Fit for a new device, synchronization may simply not begin.
Choosing the Right App for Interfacing
The first and most important step is to install the right software, as Xiaomi’s ecosystem is currently divided between the two main platforms.The latest models released in 2023-2026, including the Mi Band 8 and later, as well as the Watch S series, require the Mi Fitness app (formerly known as Xiaomi Wear), which has an updated interface and support for new data transfer protocols that are not compatible with older software.
If you have an older model, such as the Mi Band 6, 5 or 4, you can still use the classic Mi Fit app (now Zepp Life). However, it is worth noting that the company gradually migrates all users to the Mi Fitness platform, so even for older devices, it is recommended to try the new software if the old one stops supporting the account.
Download programs should be exclusively from official sources, such as Google Play Market or Galaxy Store, to avoid modified versions with malicious code.In the search box of the store, enter the name of the application and make sure that the developer is listed as Anhui Huami Information Technology or Xiaomi Inc. After installation, do not rush to open the program – first you need to prepare the phone itself.
- 📱 Mi Fitness is the main application for new devices and deep integration with the Xiaomi ecosystem.
- ⌚ Zepp Life – legacy application for old models of bracelets, the functionality of which is gradually limited.
- 🏃 Google Fit – a data aggregator that can sync with Xiaomi apps to combine statistics.
- 📲 Samsung Health is Samsung’s native app that unfortunately doesn’t have direct sync with Xiaomi without third-party plugins.
⚠️ Note: When installing the application through APK-file from a third party site you risk getting a version with an ad module or stripped down security functionality.Always use the official app stores on your Samsung.
Preparing Samsung smartphone for connection
Before you start the process of finding a device, you need to make sure that all system services on your Samsung Galaxy work correctly. Unlike older versions of Android, modern shells require explicit permission to use geolocation even for simple Bluetooth gadgets. This is due to the Bluetooth Low Energy protocol (BLE) It can theoretically be used to track the user’s location.
Open your phone's settings and go to the Connections section. Make sure the Bluetooth module is activated and visible to other devices. Next, check the location settings: they must be enabled globally, not just for specific maps. Without this permission, the intermediary app simply won't be able to detect the bracelet signal, even if it flashes in pairing mode.
It’s also worth checking for One UI operating system updates. Sometimes wearable device connection issues are solved with security patches that fix bugs in the Bluetooth stack. Go to Settings → Software Update → Download and Installation and make sure you have the latest available firmware version.
☑️ Checking before connection
The important thing is to clear the Bluetooth cache if you've had multiple devices on your phone before. Go to Settings → Apps, find the system app "Bluetooth" (click three dots in the corner and select "Show System") and click "Clear Cache." This action will not remove saved devices, but will reset temporary service errors.
Step-by-step instructions for pairing devices
The pairing process starts with the installed application. When you first sign in, you will need to create a Xiaomi Account or log in through an existing Google/Facebook profile. After authorization, go to the Profile tab or click the Add-on button, usually located in the upper right corner or in the center of the screen.
The app will ask for a number of permissions: Bluetooth access, geolocation, notifications and background work. Allow all requests, otherwise stable operation is impossible. Next click Add device and select the type of your gadget from the list. The app will start scanning the space.
At that point, you pick up the bracelet. If it's new, it automatically goes into pairing mode with the Mi logo or the Mi logo. QR-If the bracelet has been in use, you may need to reset it to factory settings through the tracker's menu. When the device name appears on the list on your phone screen, click on it.
Sequence of action:
1. Open the Mi Fitness/Zepp Life app
2. Press "+" or "Add device"
3. Select a model from the list (e.g. Mi Smart Band 8)
4. wait for the request to pair on the bracelet screen
5. Press the confirmation button (check) on the trackerThe same verification code should appear on the screen and on the wristband screen. Verify the numbers and confirm the pairing on both devices. Then the process of synchronizing the time and adjusting the user profile will begin. Don't put the phone far from the wristband at this point, the process can take from 1 to 3 minutes.
| Model bracelet | Recommended annex | Android version (min) | Features of connection |
|---|---|---|---|
| Mi Band 9 | Mi Fitness | Android 10+ | Requires a firmware update at the first entry |
| Mi Band 8 | Mi Fitness | Android 10+ | Fast pairing, support NFC-model |
| Mi Band 7 | Mi Fitness / Zepp | Android 6+ | It works with both applications, but the functionality is different. |
| Mi Band 6 | Zepp Life | Android 6+ | Best stability in Zepp Life, Mi Fitness could be bugs |
What to do if the code does not appear?
Setting up access rights and energy saving
This is the most critical stage for Samsung owners: One UI shell is known for its aggressive energy saving policy, which can "kill" the process of the Mi Fitness application when the phone screen goes out, as a result, you will stop receiving notifications, and heart rate data will be collected with tears. To avoid this, you need to manually configure exceptions.
Go to Settings → Applications, search Mi Fitness (or Zepp Life) and go to Battery. Select Unrestricted mode, which will prevent the system from forcibly closing the application. Next, in the same application menu, find the Mobile Data section and turn on the Allow Background Data option.
The next step is auto-run. Some versions of Samsung firmware have a separate auto-run menu. Make sure the switch opposite your fitness app is activated. It's also recommended to stick the app in memory: open the menu of running apps (swipe from the bottom up and hold), click on the app icon from the top and select "Secure".
- 🔋 Battery – set the “No Limits” mode for the tracker application.
- 📡 Data – allow background data transfer and roaming use (if relevant).
- 🔔 Notifications – Allow all categories of notifications, including audible and pop-up notifications.
- 🔒 Blocking – Allow display over other windows and work with a locked screen.
⚠️ Note: If you use the "Energy Saving" mode on the phone itself, all exception settings can be ignored by the system. For stable bracelet operation, this mode is better to disable or add a fitness application to the list of saving exceptions.
💡
For maximum reliability, once you have access rights set, completely close the application (click from the task menu) and run it again, ensuring that you have new power saving settings.
Solving Notification and Synchronization Problems
A common complaint of users is the lack of vibration when calling or texting Telegram and WhatsApp. The problem is often not in the bracelet itself, but in the settings for accessing notifications on the phone. In the Mi Fitness app, go to the device profile and find the "App Notifications" section. Here you need to manually turn on the switches for all messengers that you want to see on your wrist.
However, just turn on the switchboard in the application is not enough. Android requires confirmation of access. When you first turn on a notification for a specific application (for example, Viber), the system can issue a system window requesting permission. If you missed it or banned it, the bracelet will not vibrate. Check the notification settings in the intermediary application itself: there should be an "Access is allowed" status.
If the notifications are late or not coming at all, check whether the phone is on "Do Not Disturb" or "Sleep." In these modes, the system blocks unnecessary signals. It is also worth checking whether the bracelet is too far from the phone - the radius of confident reception over Bluetooth is about 10 meters without obstacles, but through the wall the signal can be lost.
To diagnose step synchronization problems, try this: open the app, pull the screen down for a forced update. If the steps don't show up, check the date and time on the phone -- time dissynchronization can lead to errors in writing data to the database. The time difference between the phone and the bracelet should not exceed 1 minute for the alarm clocks to work properly.
Additional features and widgets
Once you've set up successfully, you can set up dials, change the order of the widgets on your wristband screen, adjust your goals by steps and calories. Mi Fitness offers a rich selection of dials that you can download directly to your device.
An important feature is setting up the wrist lift to turn on the screen. The app can adjust sensitivity and time intervals when this function works (for example, only during the day or at night), and settings for periodic warm-up reminders are also available, which is useful for office workers.
Remember to update the firmware of the bracelet itself periodically. Notification of the new version appears in the device profile. Updates often contain corrections for heart rate errors and new features. The upgrade process requires a charge of at least 20% of the bracelet and a close location to the phone.
💡
The right setup of access rights in One UI is 90% of the success. Without excluding the application from the power saving mode, the stable operation of notifications on Samsung is impossible.
