Connecting the Amazfit GTS to a smartphone: full instruction with solutions to problems

The Xiaomi Amazfit GTS is one of the most popular fitness trackers due to its stylish design, long-term autonomy and wide functionality. However, new users often have questions about how to connect the device to a smartphone, what applications are needed to sync, and what to do if the clock is not determined by the phone. In this article, we will analyze the step-by-step connection process for Android and iOS owners, and also look at typical errors and ways to fix them.

It is important to understand that the synchronization process may vary depending on the smartphone model and the firmware version of the watch. For example, the Amazfit GTS 2/3/4 requires a newer version of the Zepp app (formerly Mi Fit), and the first version of the GTS may require manual Bluetooth tuning. We have taken into account all the nuances to make the instruction suitable for most versions of the device.

If you've just unpacked your watch or experienced problems after resetting, this guide will help you avoid common errors, and for those who have tried to connect but failed, there's a section at the end of this article that addresses common problems, including sync errors and Bluetooth crashes.

1.What you need to connect the Amazfit GTS

Before you start syncing, make sure you have everything you need.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ (Older versions of the OS may not have enough support for Bluetooth 4.0)
• 🔋 Charged Amazfit watch GTS (Battery level not lower than 20%, otherwise synchronization may be interrupted)
• 📲 The Zepp app (formerly Mi Fit) is the official watch management software
• 🔄 Stable Internet connection (needed for firmware downloads and updates)
• 🔒 Bluetooth enabled on your smartphone (no Visible for All mode required)

If you use the Amazfit GTS 2/3/4, check that the watch has the latest firmware installed. Outdated versions of the software can cause problems connecting to new smartphones. You can update the firmware directly through the Zepp app after the first sync.

For iPhone owners, it’s important to consider that some features (like call notifications) may work in a limited way due to Apple’s policies, and it’s impossible to install third-party dials on iOS without additional manipulation.

2.Installation and configuration of the Zepp application

The official Amazfit GTS management app is called Zepp (formerly Mi Fit), which can be downloaded for free from Google Play or the App Store, and it is important to use this software because third-party apps (such as Notify & Fitness) do not support all the functions of the watch.

After installation, follow the following steps:

1. Open the Zepp app and click Register (you can use a Xiaomi, Google or Apple ID account).
2. In the menu, click Add Device (the + icon in the upper right corner).
3. Choose the Amazfit GTS model from the list. If your version is not available, select the nearest one (e.g. GTS 2 for GTS 2e).
4. Confirm permissions to access notifications, geolocation and contacts (this is necessary for the clock to work properly).

If the app requests access to phone calls, allow it, otherwise the watch will not be able to show incoming calls. On iPhone, this item may not be available due to iOS restrictions.

💡

If the Zepp app doesn’t find the watch, try restarting Bluetooth on your smartphone or restarting the watch itself (press the button for 10 seconds).

3. Step-by-step connection of the Amazfit GTS to the phone

Now, let's move directly to synchronization. Follow the instructions carefully to avoid errors:

1. Turn on the clock (if it is turned off, press the side button for 3 seconds).
2. On the watch screen, find the Settings → Bluetooth section and activate the device search.
3. In the Zepp app, click Connect and wait for the watch to appear in the list of available devices.
4. Select your Amazfit GTS from the list. If the watch doesn't show, update the list manually (update icon in the upper right corner).
5. Confirm the pairing on the clock (may require input) PIN-code - usually 0000 or 1234).
6. Wait for the synchronization to be completed (the inscription Connected will appear on the screen).

It can take anywhere from 30 seconds to 2 minutes, depending on your Internet connection speed and the firmware version of the watch, and don't interrupt the sync, even if it seems to be stuck.

If the Amazfit GTS 3/4 watch doesn’t connect to your iPhone, try disabling the Bluetooth Power Limit feature in iOS settings (Settings → Bluetooth → Power Limit).

4. Set up notifications and basic functions

Once the connection is successful, you need to configure notifications and basic clock settings.

1. In the Zepp app, go to Device Profile → Notifications.
2. Activate the switches for Calls, SMS and Applications (select the desired messengers manually).
3. In the section Screen settings, set Brightness, Backlight Time and Autoturn.
4. For fitness functions, go to Health Monitor and activate Heart Rate, Oxygen Level and Sleep.

Android notifications are more stable than iOS, where delays can occur due to operating system limitations. If notifications do not arrive, check the power saving settings on your smartphone – some manufacturers (for example, Xiaomi, Huawei) block the background operation of applications.

If you want to use a voice assistant (like Alice or Google Assistant), you need to set it up separately in the In-app Voice Assistant section. On iPhone, this feature is only available for Siri.

5. Typical connection errors and their solutions

Even if you follow the instructions correctly, there can be problems.

🔴 The watch is not in the Zepp app

• 🔄 Reboot Bluetooth on your smartphone and watch.
• 📱 Remove the watch from the list of associated devices in the phone settings and try to connect again.
• 🔋 Check the charge of the clock – at a battery level below 15%, the connection may be interrupted.
• 📲 Update the Zepp app to the latest version.

🔴 Synchronization is interrupted or suspended

• 📶 Connect to a more stable Wi-Fi network (if cloud sync is used).
• 🔄 Turn off power saving mode for Zepp app in phone settings.
• 📵 Make sure the watch is no more than 10 meters away from the smartphone.

🔴 Notifications don't come in on the clock.

• 🔔 Check if notifications for the Zepp app are allowed in your phone settings.
• 📱 On Android, add Zepp to the list of AutoRun and Secure Apps.
• 🔄 Reconnect the clock to your phone (forget the device in Bluetooth and reconnect it).

⚠️ Note: If you are using Amazfit GTS With iPhone, disable Battery Charging Optimization for Zepp in iOS settings. Otherwise, background sync may not work.

6. Additional settings and tips

After successful connection, it is recommended to perform several additional settings for maximum convenience:

• 🔊 Set up alarms right in the Zepp app – they will duplicate on the clock even if the phone is turned off.
• 🏃 Activate Auto Tracking Training (Running, Walking, Biking) in the Sports section.
• 🔋 Enable Low Charge Reminder (defaults at 20% and 10%).
• 🌙 Set up Do Not Disturb Mode for Sleep Time to Turn Off Notifications at Night.

If you are swimming, make sure that the watch is on Pool Mode (Settings → Sport → Swimming). For the Amazfit GTS 2/3/4, swimming style tracking and lap counting are available.

To extend the battery life, disable unnecessary functions:

• 🔍 Constant pulse (if no monitoring is required) 24/7).
• 📡 Auto-renewal of weather (you can manually update).
• 🔔 Vibration at notifications (if too frequent).

💡

For stable operation of the watch, update the firmware through the Zepp app at least 1 time every 2-3 months. New versions of the software fix errors and add features.

7. Resetting and reconnecting

If the watch has started to work incorrectly (for example, does not sync, freeze or do not respond to touch), you may need to reset to factory settings.

1. On the clock go to Settings → System → Reset.
2. Confirm the action (it may be necessary to enter) PIN-code).
3. After rebooting, reconnect the watch through the Zepp app.

Resets remove all data from the clock, including:

• 📊 Training and sleep statistics.
• ⏰ Set alarm clocks and reminders.
• 🎨 Installed dials (except standard dials).

To avoid data loss, sync your watch with the Zepp app before resetting – all information will be saved in the cloud and restored after reconnecting.

⚠️ Attention: On Amazfit GTS Version 1 resetting can cause firmware to fail if the battery is discharged below 50!
