Owners of the popular Samsung Galaxy A51 often face the desire to expand the functionality of their device by adding wearable electronics. Xiaomi fitness bracelets remain one of the most popular gadgets on the market due to their autonomy and affordable price. However, the process of initial synchronization may raise questions for those who are first using the ecosystem of the Chinese manufacturer in conjunction with the Android smartphone of the Korean brand.
Successful pairing of devices gives you access to heart rate, steps, sleep quality, and notifications right on your wrist. It is important to understand that the connection procedure requires certain sequential actions that can lead to errors. In this article, we will discuss each stage of the setup in detail so that you can quickly start taking advantage of the full capabilities of your activity tracker.
Preparatory stage before synchronization
Before you go into action on the smartphone menu, make sure both devices are ready to go. Charge the Xiaomi Mi Band to a level of at least 20-30%, as at low charge, the Bluetooth module can work unstable or go into power saving mode, hiding the device from search. Also check that your Samsung A51 has geolocation (GPS) enabled, since modern versions of Android require access to location for proper Bluetooth scanning.
Note the operating system version of your phone. Android 6.0 or higher is required for stable connector applications, which is a standard situation for the A51 model, but it is still worth checking for the latest security updates. Make sure that the smartphone screen is unlocked during the search process, as the security system can block incoming pairing requests on the locked device.
⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu in Android settings.This will lead to a pairing error, and in the future the application will not be able to find the device until you remove it from the list of paired devices in the system.
You will need special software to manage the device. Mi Fit was the main attraction before, but now the company is actively promoting a new application Mi Fitness (formerly Zepp Life).The choice of the specific application depends on the model of your bracelet: for older versions (Mi Band 4 and below), Zepp Life is often recommended, and for new ones (Mi Band 6, 7, 8 and Smart Band Pro) Mi Fitness.
Installation and configuration of the connector application
The first step is to download the required software from the official Google Play Market Store.In the search, type the name of the corresponding application: Zepp Life or Mi Fitness. Avoid downloading installation files from third-party sources, as this may lead to the installation of malware or a non-working version of the program that is not compatible with your regional servers.
Once installed, launch the app and create a new account or log in to an existing one using a Xiaomi Account, Google or Facebook. Registration is mandatory, as it is on the manufacturer's servers that your activity statistics and user profile are stored. The first time you log in, the app will request a number of permissions, among which access to Bluetooth, geolocation and notifications are critical.
In the application interface, go to the Profile or Mine tab, usually located at the bottom right of the screen, and here is the add button for a new device. Click on the plus or add device button, and the program will start scanning the surrounding space, at which point the system will look for compatible gadgets that are in pairing mode.
- 📱 Make sure the application has permission to work in the background, otherwise the data synchronization will be interrupted.
- 🔒 When requesting access rights to contacts and calls, agree if you want to see the name of the caller on the screen of the bracelet.
- 📍 The geolocation permit must be set to Always or When using the App for proper route tracking.
💡
If the app is looking for a device for a long time, try restarting the smartphone and running the search again - this clears the Bluetooth stack cache.
The process of pairing devices
When the app goes into search mode, a list of available devices will appear on the smartphone screen, and if your bracelet is new, it will automatically go into pairing mode when you first turn on. On the tracker screen, a vibration or Bluetooth icon may appear, as well as a request for confirmation of pairing (check).Click on the name of your device in the list on the Samsung screen A51.
When you connect to your wristband and smartphone, you may have confirmation codes on your screen, make sure the numbers match, and confirm the action on both devices, and this security mechanism protects you from connecting to other devices nearby, and once you've successfully confirmed, you'll start synchronizing the time and basic settings.
It is important to stay close to the phone at this point and keep the app screen active. If the connection is interrupted at the progress percentage stage, the procedure will have to be repeated. Sometimes the Android system may request confirmation to create a pair through the system pop-up - be sure to click "Connect" or "OK".
☑️ Checklist of successful connection
Once the communication is complete, the app will suggest adjusting the basic parameters: select the hand (left or right), set goals by steps, and adjust the display of the dial. These settings can be changed at any time, but the initial calibration is important for correct counting of the accelerometer data.
Set up notifications and permissions for Samsung A51
Samsung’s One UI shell is known for aggressive battery optimization that can kill application background processes, including a fitness bracelet app. To keep messenger and call notifications steady, you need to manually configure exceptions. Go to Settings → Apps, find your app (Mi Fitness or Zepp Life) and select Battery.
Select Unrestricted from the battery menu, which will prevent the system from restricting the application from running in the background, then allow auto-start. In some firmware versions, this option is located in the Auto-Start section of the general application settings or through the device optimization menu.
| Setup parameter | Where to find in the Samsung menu | Recommended value |
|---|---|---|
| Energy consumption | Settings → Applications → [Application Name] → Battery | No restrictions. |
| Auto-start | Settings → Applications → [Application Name] → AutoRun | Included. |
| Working in the background | Settings → Device Care → Battery → Restrictions in the background | Application is unlimited |
You also need to activate notifications. In the fitness bracelet app itself, go to the device profile and find the "App Notifications" section, where you will see a list of all the programs on your phone, activate the switches opposite the apps you want to see messages from on your wrist (Telegram, WhatsApp, Viber, calls, SMS).
⚠️ Warning: If notifications don’t come after all the settings, check if the phone has either “Do Not Disturb” or “Sleep” mode on it, which can block the vibration of the bracelet.
Solving Common Connection Problems
Despite the simplicity of the procedure, users may encounter technical difficulties. One of the common problems is that the phone sees the device but does not connect, or the connection immediately breaks. In this case, you need to perform a full reset of Bluetooth settings on the smartphone. To do this, go to Settings → General Settings → Reset → Network settings. Note that this action will delete stored Wi-Fi passwords and associated Bluetooth devices, but will not affect personal data.
Another common reason is the application version conflict: If you used the bracelet with another phone before, it might have been attached to an old account or app, you need to remove the device from the old application through Unbind, rather than just remove it from Bluetooth, and only after untieing the bracelet will become visible again for new connections.
- 🔄 Reboot both devices – it solves 80% of problems with software failures.
- 🗑️ Remove the device from the Bluetooth list in Android settings if it is “hanging” there».
- 📲 Reinstall the connector app by pre-clearing its cache in your phone settings.
If the bracelet has stopped responding to buttons and is not displayed in the search, it may have gone into deep sleep or hung.Put it on charge for 10-15 minutes.Plug into the power supply often forcefully wakes the device and restarts its software module.
What if the bracelet shows the wrong time?
Additional features and fine tuning
Once you've successfully connected, you've got a lot of customization options, you can download new dials that dramatically change the look of the device, and there's thousands of options available in the Cloud store, from minimalist handhelds to complex informational dials with lots of widgets.
An important function is to adjust the wrist lift. The wristband can turn on the screen when you raise your hand to see the time. The sensitivity of this sensor can be adjusted, as well as set time intervals when this function is not needed (for example, at night during sleep, so that the light does not interfere).
Samsung A51 users will benefit from a phone search feature, which is that if you lose your smartphone in your apartment, start this feature on your bracelet and your phone will ring loudly, and vice versa, you can make the bracelet vibrate if you lose it.
💡
Properly configuring the application’s power consumption in the Android system is the key to stable notifications and data synchronization without communication breaks.
