The integration of ecosystems from different manufacturers often raises questions among users, especially when it comes to the mix of Android smartphones and Wear OS gadgets. Owners of Xiaomi devices often wonder whether it is possible to fully use the functionality of the Samsung Galaxy Watch 4 without a Samsung phone. The answer is yes, but the process requires attention to detail, since the standard configuration algorithm will not work here.
The main difficulty is that the Galaxy Watch 4 is powered by the Wear OS operating system, which requires specific services and plugins that are usually preinstalled in Samsung smartphones. On Xiaomi devices, these components are absent by default, which leads to errors when trying to initially register the watch through a standard application.
In this article, we will take a look at all the preparation, installation of hidden components and final configuration steps, learn exactly what apps you need, how to avoid cyclical reboots and how to ensure that notifications work consistently. Follow the instructions Step-by-step to turn your watch into a powerful tool that works in tandem with your Xiaomi smartphone.
Preparation of Xiaomi smartphone for the installation of Wear OS
Before you start the pairing process, it is critical to prepare your Xiaomi software environment. Standard MIUI or HyperOS power saving settings can aggressively restrict the background operation of applications, which will lead to permanent breaks in the Bluetooth connection, so the first step is to change the security settings and permissions.
You need to go to the security settings and allow the installation of applications from unknown sources, as some necessary components may not appear in the regional Google Play store or require installation of applications. APK-File settings. → Annexes → Install unknown applications and select your browser or file manager, giving them full rights.
It is also worth disabling battery optimization for all applications that will be involved in the process: Google Play Services, Wear OS and Samsung Plugins. this will prevent the system from killing processes during the initial synchronization, which can take up to 15-20 minutes.
⚠️ Warning: Before setting up, make sure that both devices are at least 60% charged.The process of initial plug-ins and watch firmware updates can be energy intensive and a sudden shutdown will result in pairing error.
Don’t forget to enable Bluetooth and GPS (geolocation) on your smartphone. Without active geolocation, modern versions of Android won’t allow you to search for Bluetooth devices to pair. Make sure you’re in a Wi-Fi confident area, as the watch may require you to download updates during the setup process.
Necessary applications and system plugins
The key thing that makes connecting the Samsung Galaxy Watch 4 to Xiaomi impossible is to install three specific plugins. Google’s regular Wear OS app isn’t enough here. You’ll need to find and install three components that are usually hidden from users of non-Samsung devices.
The first and most important component is the Galaxy Wearable plugin, which tells the system that the phone is compatible with the clock and allows you to complete the registration process, without which the setup process will go on forever in the "Search for Updates" or "Connection interrupted".
Where to download the secure version of plugins?
The second element is Samsung Accessory Service, which is responsible for data transfer between the phone and the clock, including contact synchronization, call history and dial settings. The third component is the Galaxy Wearable app itself, which is the watch control center.
The order of installation matters. System plugins are installed first, and only after their successful installation can the main application be launched. If this sequence is broken, Galaxy Wearable may not see the previously installed components and require them to be rebooted, which may not be successful.
- 📱 Galaxy Wearable – the main application for managing the clock, setting up dials and installing applications.
- 🔌 Samsung Accessory Service – background service for stable communication and data transmission.
- ⚙️ Galaxy Watch 4 Plugin – a critical module emulating the presence of a Samsung smartphone for successful watch registration.
Step-by-step instructions for pairing devices
Once all three apps are installed, you can switch to direct pairing. Turn on the clock if it's turned off, or reset to factory settings if previous connection attempts left configuration errors. On the watch screen, select the language and click "Start."
Launch the Galaxy Wearable app on a Xiaomi smartphone. Press Start or Connect New Device. The system will ask for permission to access contacts, microphone and location — agree with all queries. Search for Bluetooth devices will begin.
When the Samsung Galaxy Watch 4 appears on the list, click on it. The confirmation code will appear on the watch and phone screen. Make sure the codes match and confirm the action. Then the "Setting up the Galaxy Watch" process begins, which is where most users experience errors if the plugins are installed incorrectly.
☑️ Checklist before the start of the pairing
The system will offer a software update to the watch, a must-have for non-Samsung phones, as newer versions of Wear OS contain compatibility patches. Wait until you complete the download and install the updates without interrupting the process.
After the update, you will be prompted to set up health features, a Samsung account and backup.It is recommended to sign in to your Samsung account to be able to install apps from the Galaxy Store and use the Find My Device feature.
Permissions and MIUI/HyperOS optimization
Xiaomi shells are known for their aggressive memory management policy.To ensure that the Samsung Galaxy Watch 4 does not lose touch with the phone an hour after being removed from the wrist, you need to manually adjust the operation of background processes.
Go to your phone's settings, select the Apps section, and find Galaxy Wearable. Go to Activity Control (or Battery) and select No Limits mode, which will prevent the system from killing the app to save energy. The same procedure should be repeated for Samsung Accessory Service and Wear. OS».
It’s also important to check autorun. In the app settings menu, look for “Sunset” and make sure the switches for all Samsung and Google Wear OS components are activated, ensuring that services start immediately after the phone is turned on.
| Component | Auto-start permit | Activity monitoring | Additional permits |
|---|---|---|---|
| Galaxy Wearable | Included. | No restrictions. | Everything (Contacts, SMS, Phone) |
| Samsung Accessory Service | Included. | No restrictions. | Location, Bluetooth. |
| Wear OS | Included. | No restrictions. | Microphone, Camera |
| Google Play Services | Included. | No restrictions. | All systems. |
Another important aspect is working with notifications. In the Galaxy Wearable app, go to Notifications and make sure the Show Notifications switch is active. Then select the ones you want to see on your watch from in the app list (Telegram, WhatsApp, Viber, etc.).
⚠️ Note: If notifications don't come, try removing the messenger app from your watch and installing it again through the Galaxy Store or Play Market on the watch itself.
Solving common problems when connecting
Even if all instructions are followed, technical difficulties can arise, and one of the common problems is the “update cycle”, where the clock constantly requires software updates, but after downloading and installing the process begins again, often due to lack of cache space or conflicting versions of plugins.
To solve this problem, try clearing the cache and data of the Galaxy Wearable and Samsung Accessory Service app on your phone. Then reset the clock to factory settings (hour menu → Settings → General → Reset) and start the pairing process again. Make sure the plugin versions match each other.
Another common mistake is that you can’t install apps from the Galaxy Store on your watch, because the store requires certain Samsung system libraries, and in some cases, installing the Samsung Pay Plugin plugin (even if you don’t plan to use the payment) helps, as it tightens the missing dependencies.
💡
If the watch stops responding or freezes on the Samsung logo, perform a forced reboot by holding both side buttons simultaneously and holding them for about 7-10 seconds until the Android/Wear OS logo appears.
Bluetooth connection issues when the watch is plugged in and out are often solved by “forgetting” the device in the phone’s Bluetooth menu. Remove the watch profile from the list of paired Bluetooth devices in your Android settings, but don’t remove it from the Galaxy Wearable app.
Functional capabilities and limitations of the link
Using the Samsung Galaxy Watch 4 with Xiaomi will give you access to 90% of the functionality, but some exclusive features will remain unavailable.
First of all, non-Samsung phones do not have ECG and blood pressure recording features, which are software-locked and require Samsung Health Monitor, which is certified only for Samsung smartphones in most regions.
In addition, you won’t be able to respond to messages with voice or text directly from the clock (Quick Reply feature) if you use a standard Google keyboard. To fully work, you will need to install third-party keyboards that support Wear OS, such as Gboard, configured specifically for the watch.
- ✅ Working: Notifications, sleep tracking, step counting, SpO2, NFC-Payment (via Google Pay if supported by a bank), application installation.
- ❌ Not working: ECG removal, pressure measurement, Find My Phone (watch phone search), alarm clock synchronization in both directions.
- ⚠️ Works with limitations: Voice input (requires settings), Samsung Pay (unavailable, used by Google Pay).
Despite the limitations, the bundle remains very popular thanks to its excellent AMOLED screen, processor speed and rich dial selection. For Xiaomi users, it is often the only way to get a full Wear OS experience with a premium design.
💡
The main value of the Xiaomi + Galaxy Watch 4 bundle is access to the Wear OS ecosystem and Samsung’s high-quality hardware, despite software limitations in the field of health.
