Where do I look for plugins?
Pay special attention to the operating system version. The Galaxy Watch 3 requires Android version 6.0 or higher, however, for stable performance of all health features and payments, it is better to use Android 10 and later. If your Xiaomi runs an older version of Android, some features may not be available.

Power saving settings in MIUI and HyperOS
This is the most important section of the instruction. Xiaomi shells are known for their aggressive work with background processes. The system seeks to kill any application that actively uses Bluetooth or network to save battery power. Unless you set exceptions, the connection between the phone and the clock will break every time the smartphone screen goes out.
You need to find the application section in the phone settings → All apps.Look for Galaxy Wearable, Samsung Accessory Service, Watch3 Plugin and Samsung Health. For each of these apps, follow the following steps:
- 🔋 Energy saving: Select the option "No restrictions" and this will prevent the system from disabling the application.
- 🚀 Autostart: Turn on the switchboard so that services run along with the phone.
- 🔒 Fixing in memory: Open the menu of running apps (bottom-up swipe and retention), find the Galaxy Wearable window, click on the lock or select “Place».

Solving Notification and Synchronization Problems
A common complaint of Xiaomi users is that there is no vibration or sound when messages are sent in messengers. The problem is that the watch does not have access to app notifications installed on the phone. In the Galaxy Wearable app, go to Settings of the watch → Notifications. Here you will see a list of all the apps.

If notifications are late, try finding your connected watch in your phone’s Bluetooth settings and enabling Media Sound or Contacts in their properties, even if you don’t plan on listening to music through the clock, which sometimes changes the connection’s priority.
Also check the settings of the messenger app itself. In some cases, Telegram or WhatsApp has its own notification settings, where you need to allow notifications to be displayed on wearable devices. Make sure that the phone itself does not turn off notifications in Do Not Disturb mode.
Samsung Health and Activity Monitoring
To fully work, the pedometer, pulse meter and sleep tracker need to install the Samsung Health app. On Xiaomi devices, it may not be installed directly due to a security certificate check. If the installation error occurs, “Device is not supported”, you will need to use special modified versions of the application or use the utility to change the region.
However, a simple workaround often helps: install the Samsung Health app, then in your phone settings (Settings → About Phone) quickly tap 7 times on the MIUI version to open the developer menu, and try changing the phone region to a country where Samsung services work without restrictions (for example, Kazakhstan or Germany), then reinstall the application.
