Modern wearable gadgets from Huami, working under the brand Amazfit, often chosen by owners of Xiaomi smartphones because of the optimal ratio of price and functionality. However, the process of initial synchronization of these devices sometimes raises questions, especially given the aggressive optimization of the battery in the shell MIUI and HyperOS. Proper configuration at the start is the key to stable operation of the Bluetooth connection and the correct arrival of notifications in the future.
Unlike simple fitness bracelets, the GTS 2 model requires not only standard pairing through the system menu, but also mandatory authorization in a proprietary app to activate all functions. Ignoring even one step can lead to the watch displaying time, but not transmitting health data to the phone. We will analyze the entire process in detail to exclude any connection errors.
Preparation for interconnection of devices
Before starting the procedure, you need to make sure that both devices are ready to work. On the Amazfit GTS 2 watch, the battery must be charged at least 20-30% so that the process of installing updates or synchronizing data does not stop suddenly.
Xiaomi smartphone should activate Bluetooth module and geolocation. Android system requires access to location for scanning BLE-Low Energy, which includes smartwatches, without switching on GPS Searching for a gadget may simply not give results, and the phone won’t see the watch in the list of available.
It is also critical to download the official Zepp app (formerly known as Amazfit), which is the software that provides the basic setup, watch firmware and profile management, and is best downloaded from the official Google Play store or App Store to avoid modified versions that may not work properly with new versions of Android.
💡
Make sure your phone is Bluetooth enabled, but don’t try to connect the clock directly through the Bluetooth system menu until you have completed the setup in the Zepp app.
Installation and configuration of the Zepp application
Once you download and install Zepp on your Xiaomi, launch the app, you need to create an account or log in to an existing one using email, phone number or social media accounts, and this is necessary to save your activity history in the cloud. Without registration, the functionality of the watch will be severely limited.
In the main menu of the application, click on the Profile tab, and then select the Add Device button. In the list of available gadgets, find Amazfit GTS 2. The application will automatically go to search mode. At this point, a request for confirmation of pairing may appear on the watch screen - agree with it by clicking the tick.
MIUI can request a number of permissions for the Zepp app. Be sure to provide access to contacts, calls, SMS, location and notifications. If you deny access at this stage, the watch will not be able to display incoming calls or messages from messengers. This is standard Android security procedure.
⚠️ Attention: Don’t ignore permission request pop-ups. Xiaomi’s shell often requires double confirmation: first system, then inside the app itself.
☑️ Access rights verification
Synchronization process via Bluetooth
When the app finds your watch, a digital code will appear on your smartphone screen and on the GTS 2 display. Check the numbers carefully: they must match. If the codes are identical, confirm the action on both devices. This is protection against connecting to other devices nearby.
Once confirmed, the initial synchronization process will begin, at which time the clock may display the Amazfit logo or boot indicator, do not move the smartphone far from the clock and do not lock the phone screen so that the system does not interrupt data transmission, usually this step takes 1 to 3 minutes.
The important thing is to update the firmware of the watch itself. The Zepp app will immediately check the version of the installed software. If a new version is available, it is recommended to update immediately. This fixes known connection bugs and improves the operation of the sensors. The process will take about 5-10 minutes, and the watch can be restarted.
What to do if the code does not appear?
Configure notifications and permissions in MIUI
Xiaomi owners need to do an additional setup, as the aggressively system manages background processes. To ensure that notifications come in stable, go to Settings → Apps → All apps. Find in the Zepp list and go to the Other Permissions section.
You need to activate all the items, especially Autostart and Background Display. Without autostart permission, the system can kill the sync process a few hours after use, and the clock will stop vibrating when you call, a common problem that is often forgotten.
Then, in the Zepp app itself, go to the watch profile and select "Application Notifications." Turn on the switches for the programs you want to see on your wrist: Telegram, WhatsApp, Viber, etc. You can also set the vibration when you call.
| Setup parameter | Where to find out. | Recommended value |
|---|---|---|
| Auto-start | Phone settings → Applications | Permitted. |
| Working in the background | Phone settings → Battery | No restrictions. |
| Bluetooth | System settings | Included. |
| Geolocation | System settings | Included (for search) |
💡
Without setting “No Limits” in the battery section, Xiaomi’s system will block the Zepp app from running in the background.
Connection problems and their solution
Sometimes the installation process is not smooth. If a Xiaomi phone can't see the watch, the first thing you do is check if it's already paired with another phone. The Amazfit GTS 2 can only store a connection to one active device. Break the connection in the app on the old phone or reset the settings on the watch itself.
Another common reason is the Bluetooth cache. Try finding the Bluetooth partition in your phone's settings, searching for the Amazfit GTS 2 list (if there is one), and clicking "Forget the device" or "Cancel pairing." After that, restart your smartphone and repeat the search procedure through the Zepp app.
If the problem persists, check the Android version and the app itself.The outdated version of Zepp may not work properly with the new security protocols. Update the app through the store, and check for system updates for MIUI.
⚠️ Warning: If you reset your watch to factory settings, all the accumulated statistics on it will be deleted. Make sure the data is synced to the cloud before this action.
Hidden Functions of the Developer Menu
Use of Call and Music Functions
The GTS 2 has a microphone and speaker that allows you to take calls from the clock, and for this to work, the Zepp app must have microphone and phone access rights on it, and when you call in, the response interface will appear on the watch screen.
To control music, you need to run any player on your smartphone, and the watch automatically detects the track you're running and lets you switch songs or adjust the volume, which is convenient when you're training when your phone is in your pocket or on your belt.
The sound quality of a conversation depends on the level of ambient noise and the distance between the phone and the clock. Bluetooth connection provides stable voice transmission at a distance of up to 10 meters without obstacles. In a room with concrete walls, the range can be reduced.
💡
For better sound quality during a conversation, try not to close the microphone area located on the side of the watch body with your palm.
