Using the Galaxy Wearable application
For owners of devices from the South Korean giant, the main management tool is the utility Galaxy Wearable. This is a central control panel that takes care of all the initial setup, updating the watch firmware and installing plugins. You can download the application for free from the official application store by entering the appropriate query in the search bar.
After installation and launch, the app will automatically start scanning the surrounding area in search of available devices. If your watch is in pairing mode (usually it goes into it immediately after turning on or resetting the settings), it will appear in the list of available gadgets on the screen Samsung A51.
The connection process requires confirmation of the code, which will be displayed on both screens. This is a security measure to ensure that you are connecting to your device and not your neighbor's watch. After entering or confirming that the codes match, the process of registering the device in the system will begin.
If the automatic search does not produce results, try clicking the "Search for devices" button manually in the Galaxy Wearable application or restarting Bluetooth on your phone.
It is important to note that for some functions to fully work, for example, receiving calls or installing third-party applications on the watch, you may need to install additional plug-ins, which Galaxy Wearable will offer to download automatically. Failure to install these components may limit the functionality of the wearable gadget.
Pairing via the standard Bluetooth menu
Not all wearable gadgets require complex proprietary software for basic synchronization. Simple fitness bracelets or watches with minimalist functionality can often be connected directly through the standard wireless connection menu Android. This method is especially relevant if you do not want to clog up your phone memory with unnecessary applications.
To do this, you need to open your phone settings and go to the Connections → Bluetoothsection. Make sure the slider is enabled and click Search for Devices or Scan. The phone will begin searching for all available signals within a radius of several meters.

| Device type | Connection method | Required application | Functional |
|---|---|---|---|
| Samsung Galaxy Watch | Galaxy Wearable | Galaxy Wearable + Plugins | Full (calls, NFC, applications) |
| Xiaomi Mi Band | Bluetooth + Mi Fitness | Mi Fitness / Zepp Life | Fitness, notifications, time synchronization |
| Huawei Watch | Bluetooth + Health | Huawei Health | Health, notifications, music control |
| Generic Smartwatch | Bluetooth (direct) | Depends on the model (often BTNotification) | Basic notifications, time, pedometer |
It is worth considering that when connecting through the standard Bluetooth menu without using functionality of a proprietary application may be limited. You will be able to see the time and possibly receive notifications, but detailed settings for watch faces or export of health data will not be available.
Setting access rights and permissions
Modern versions Android, including skins One UI based on Samsung A51, pay increased attention to data privacy. After connecting the watch, the system may limit background work of the companion application to save power, which will lead to a disconnection or lack of notifications.
To avoid this, you need to go to the application settings, find the installed watch manager and check the permissions granted. Critical are access to location (needed for the operation of the Bluetooth scanner), contacts, call log and notifications. Without these permissions, the smartwatch turns into a regular digital timer.
⚠️ Attention: The permission settings interface may differ depending on the Android security update version. If you don't find the item you need, use the search inside the phone's settings menu.
It is also recommended to disable aggressive battery optimization for the clock management application. This can be done in the Applications → [Your application] → Battery → Optimizationsection by selecting “Do not optimize”. This will allow the application to constantly communicate with the watch, even if the phone screen is off.
