Samsung Galaxy Watch 3 and Xiaomi: full instructions for connecting

Xiaomi smartphone owners who choose to use Samsung smartwatches often face the unobvious difficulties of initial setup. Despite the fact that the Galaxy Watch 3 runs on Tizen OS, and Mi phones use Android with a MIUI shell or HyperOS, their collaboration is quite possible. However, the standard “found-connect” algorithm will not work here due to the aggressive policy of power saving Xiaomi system.

The main problem is that background processes on Xiaomi devices are tightly controlled, which leads to constant breaks in the Bluetooth connection and no notifications. To work consistently, you will need not only to install the application, but also to set up the system permissions correctly. The key is to install the Watch 3 Plugin plugin, which does not appear in the Play Market search without first activating through the main Samsung applications.

In this article, we’ll break down the full setup cycle, including hidden steps that beginners often miss. You’ll learn to bypass MIUI system constraints to make your Samsung gadget work as smoothly as it does when paired with your native smartphone.

Preparation for interface and installation of components

Before starting the procedure, make sure your Xiaomi has Bluetooth and geolocation enabled. GPS-The process of finding the watch can be delayed or error-prone. Also check the charge of both devices: to start the setup, it is recommended to have at least 50% of the energy in the battery of the Galaxy Watch 3.

The first step is to download the required software from the Google Play store, and you will need to find and install two main apps from the watch manufacturer. Don't try to search for them through third-party resources, as this can lead to the installation of modified and insecure versions.

• 📲 Galaxy Wearable – the central application for managing all watch settings.
• ⌚ Watch 3 Plugin – a specific plugin, necessary for the model Watch 3.
• 🔌 Samsung Accessory Service – a service component for data exchange between devices.

It's important to follow the sequence of installation. First download the Galaxy Wearable, launch it, and start searching for the device. At some point, the system itself will suggest downloading the Watch 3 Plugin. Attention: if the plugin did not download automatically, interrupt the process, manually search it in the Play Market, install and run the search again.

⚠️ Note: On some versions MIUI When installing the plugin, a muncul message about an “unknown source” may be allowed, as the file is downloaded through an official store, but Xiaomi’s security system is reinsurable.

The pairing process and initial setup

Once you have installed all the components, open the Galaxy Wearable app and click Start. The phone will start scanning the available devices. Once your Galaxy Watch 3 shows up on the screen, select them from the list. The watch and smartphone screen will have confirmation codes — check them out and click Confirm on both devices.

This is followed by a software update to the watch, which can take 10 to 30 minutes depending on the firmware version originally installed on the watch, and don't interrupt the process and keep the phone next to the watch, and interrupting the update can cause a software failure, after which the watch will have to be reflashed through the PC.

In the initial setup process, the system will prompt you to sign in to your Samsung Account, a requirement for the app store and some health features, and if you don’t have an account, create it in advance or during the setup process.

Critical MIUI setup for stable operation

This is the most important section of the instruction. Without doing the following, Xiaomi will kill the Galaxy Wearable process a few minutes after the screen is turned off, and you will stop receiving notifications.

Go to Settings → Apps → All apps. Search in the Galaxy Wearable list, click on it and select Battery. Set “No Limits.” Repeat the same procedure for the Watch 3 Plugin and Samsung Accessory Service, which will allow apps to run in the background without restrictions.

Then you need to configure autorun. In the same app settings menu, find Autorun and activate it. Also go to Permissions and grant the app all the rights you request, especially access to location, contacts, phone and notifications. Failure to any of these will result in incorrect operation.

To ensure full stability, it is recommended to fix the applications in memory. Open the menu of running applications (square or swipe at the bottom), find the Galaxy Wearable window, pinch it or press the lock in the corner to lock. Now, even if you clear the memory with the “clean all” button, Samsung services will remain in RAM.

Set up notifications and health features

Once you have successfully paired and configured the power saving, you need to activate notifications. In the Galaxy Wearable app, go to Notifications. Here you will see a list of all the apps on your Xiaomi. Turn on the switches for the programs you want to see messages from on your wrist: Telegram, WhatsApp, Viber, SMS and others.

For health-watchers, it’s important to know that certain features can work with limitations, such as ECG and pressure measurements officially only available in conjunction with Samsung smartphones. However, basic heart rate, sleep and footstep monitoring works well, and the data is synchronized with Samsung Health, which will also need to be installed and configured on Xiaomi.

If notifications are late, try restarting both devices after you have completed all the power saving settings, often shaking the system and forcing MIUI rules to apply correctly.

Personalization of dials and interface

One of the strengths of the Galaxy Watch 3 is the ability to fine-tune the look. The Galaxy Wearable app has a Dial section available. You can choose from a variety of free options or download new ones from the Watch Faces store.

For advanced users, the Always On Display setting is available, and you can choose whether the screen will burn constantly, turn on on on schedule, or only when you raise your wrist, which significantly affects the autonomy of the device.

💡

Use dark dials with minimal parts for Always On Display mode – this reduces the risk of AMOLED matrix burnout and saves battery life.

You can also change the behavior of the buttons in the watch settings menu, so you can double-press the top button to run a specific application, such as a pulse monitor or alarm clock, which makes it easier to control your gadget in everyday life.

Troubleshooting and troubleshooting

Even when you set up correctly, there can be situations where communication is lost. If the watch stops responding or notifications are gone, the first thing you do is check if Bluetooth is asleep. Go to the Bluetooth settings on your phone, find your watch, click on the gear next to it and select "Unpair" and then reconnect.

Time desynchronization is a common problem. If the clock is out of sync, check the date and time settings on the Xiaomi phone itself. Make sure you automatically determine the time over the network. Also, in the Galaxy Wearable app, in the About Watch section, you can find the Reset option, which often solves software glitches without completely flashing.

⚠️ Warning: If the watch stops charging or is warming, immediately stop using.The problem may be a cable or power supply.Use only original or certified chargers with a current of no more than 1A.
