5. Solving common connection problems

Even with proper configuration, users X8 Pro sometimes encounter errors. Let's look at the most common of them and how to fix them.

Problem 1: The watch connects, but the application does not see it

This happens if:

• The application Da Fit is not updated (check the version on Google Play).
• The phone has power saving mode enabled for Da Fit.
• The watch was previously connected to another phone (you need to reset it to factory settings).

Solution:

1. Remove the watch from the list of Bluetooth devices on the phone.
2. Reset your watch: Settings → System → Reset.
3. Reinstall the application Da Fit.

Problem 2: The connection keeps dropping

Culprits:

• Weak Bluetooth signal (maximum distance - 10 meters without obstacles).
• Conflict with other connected devices (headphones, fitness bracelets).
• Background optimization of Android (especially on Xiaomi, Huawei, Samsung).

Solution:

• Disable other Bluetooth devices.
• In the phone settings, add Da Fit to startup and optimization exceptions.
• Reboot both devices.

Problem 3: Notifications do not arrive

Check:

• Is notification access allowed for Da Fit in Android settings.
• Are notifications for specific applications (WhatsApp, SMS, etc.) disabled in Da Fit.
• Is the Do Not Disturb mode on the watch blocking them.

Problem 4: The watch does not charge

Possible reasons:

• 🔌 Faulty cable or adapter (try another).
• 🔋 Dirty contacts on the watch (wipe them with an alcohol wipe).
• 📱 Non-original charger (use 5V/1A adapter).

⚠️ Attention: If after all the manipulations the watch X8 Pro still does not connect, check its firmware. Some batches come with outdated software that is not compatible with Android 12+. Update the firmware through the official application or contact manufacturer support. The contacts are usually indicated in the instructions or on the box.

6. Firmware update and factory reset

If the watch is unstable (freezes, does not synchronize, discharges quickly), a firmware update or reset to factory settings may be required.

Firmware update

The manufacturer periodically releases updates for X8 Pro, fixing bugs and adding new features. To update the software:

1. Connect the watch to the phone via Da Fit.
2. Open the section in the application Profile → About device → Software update.
3. If a new version is available, press Update and wait for the process to complete (do not turn off the watch!).

Factory reset

This procedure will delete all data from the watch (steps, settings, profiles). Use it if:

• The watch freezes or does not respond to touches.
• You cannot connect to the phone after several attempts.
• The application Da Fit does not recognize the device.

For reset:

1. On your watch, go to Settings → System → Reset.
2. Confirm the action (usually you need to hold the button for 5 seconds).
3. After rebooting, repeat the connection process from scratch.

If after resetting the watch does not turn on or is stuck on the logo, try:

• 🔌 Connect it to the charger for 30 minutes (sometimes a dead battery blocks booting).
• 📱 Reset the settings again by holding the side button for 15-20 seconds.

⚠️ Attention: Flashing and resetting are extreme measures. If the watch is working stably, do not update the software unless necessary. An incorrect update can lead to the device being “bricked” (completely inoperable).

7. Alternative connection methods (without the official application)

If the application Da Fit does not suit you or does not work on your phone, you can try alternative connection methods. They will provide limited functionality, but will allow you to use the watch as a Bluetooth headset or fitness tracker.

Method 1: Connect as a Bluetooth device

This method will allow you to receive calls through the watch, but without notifications and health monitoring:

1. On your phone, open Settings → Bluetooth.
2. Find X8 Pro in the list and connect as if to a headset.
3. In call settings (Settings → Calls → Audio route) select X8 Pro as audio output device.

Method 2: Third-party applications

Some universal applications for smartwatches support X8 Pro:

• Notify & Fitness —for notifications and basic tracking.
• Tools & Mi Band —an alternative for activity monitoring.

However, please note:

• 🚫 These applications may not support all functions X8 Pro (for example, measurement SpO₂).
• 🔄 Data synchronization will be less stable.
• 🛡️ There is a risk of data leakage (third-party applications are not always safe).

Method 3: Connection via Wear OS (for advanced users)

Some firmware for X8 Pro allow you to connect the watch to Wear OS (Google), but this requires manual installation of custom software and may void the warranty. This method is only suitable for experienced users, since:

• ⚠️ Risk of turning the watch into a "brick".
• 🔧 Requires bootloader unlocking and firmware via PC.
• 📱 Not all functions will work correctly.
