Modern smart watches have ceased to be just an addition to a smartphone and have turned into a full-fledged means of communication. The model X8 Pro from popular Chinese brands such as Lemfo or W26often arouses interest among users due to its stylish design and affordable price. However, one of the most popular functions remains the ability to make and receive calls directly from the wrist without removing the phone from your pocket.
The Watch Call function (or simply calls through the watch) is implemented in these devices via a direct Bluetooth connection to the main gadget. This means that the watch uses the microphone and speaker of the smartphone, broadcasting the sound to the wrist. For owners of Androiddevices, the setup process usually goes smoothly, but requires compliance with a certain sequence of actions in system menus and specialized applications.
In this article we will look in detail at how to activate the call mode, what applications are needed for synchronization and what to do if the device does not see the network. You will learn about the intricacies of Bluetooth protocols in budget wearable gadgets and how to avoid common mistakes when starting up for the first time. Correct setting will ensure a stable connection and allow you to stay in touch even when the phone is far away.
The principle of calls on the X8 Pro and system requirements
Before moving on to the technical part, it is important to understand the architecture of interaction between the watch and the phone. Smartwatches X8 Pro do not have their own SIM module (in basic versions) and do not support eSIM. All the magic Watch Call is built on Bluetooth Hands-Free Profile (HFP) technology. This is a profile that allows one Bluetooth device (watch) to control the voice communication of another device (smartphone).
When you receive a call on the watch, the signal goes from the telecom operator to your phone, and the phone, in turn, transmits the audio stream to the headset, which in this case is the watch. It is critical to understand that for the function to work, the phone must be within Bluetooth range, usually no more than 10 meters without obstacles. If the connection is interrupted, the call will also be interrupted or switched to phone speaker.
The system requirements for the smartphone are minimal, but they must be met. The operating system Android must be version 5.0 or higher, although for stable operation of modern synchronizer applications it is better to have Android 8.0+. A stable Bluetooth 4.0 or higher module is also required, as older versions may not support simultaneous data and voice transmission with low power consumption.
⚠️ Warning: Some custom Android skins (e.g. MIUI, EMUI, ColorOS) may aggressively save power and force the watch to close background processes. This may result in the watch not vibrating when there is an incoming call.
To ensure stable operation, you must grant the companion application all requested permissions. Without access to contacts, microphone and call log, the function Watch Call will not work. The Android security system strictly controls these accesses, so pop-ups asking for permissions cannot be ignored.
Preparing for synchronization: installing software and resetting settings
The first step towards activating calls is installing the correct software. Clock X8 Pro often come with a QR code in the menu or on the box that leads to downloading the application. The most common applications for this model are WearPro, WearFit Pro or Fundopro. The exact name depends on the specific batch and manufacturer of the board.
Do not try to connect the watch directly through the standard Bluetooth menu in the Android settings as a regular headset before installing the application. This is a common mistake that leads to conflicts. First you need to install the application, register in it (sometimes an email is required) and only then start searching for the device inside the app.
- 📱 Scan the QR code from the watch screen or find the application on Google Play by the name specified in the instructions.
- 🔌 Make sure that the watch has at least 50% charge so that it does not turn off during the pairing process.
- 🔍 Turn on geolocation (GPS) on your phone - without this, Android 6.0+ will not allow scanning of Bluetooth devices.
If you have previously tried to connect your watch and something went wrong, be sure to reset it. In the watch menu, find the item Settings → Bind & Reset or More Settings → Reset. On your phone, go to the Bluetooth settings, find the device with the name X8 Pro (or similar) and click “Forget device” or “Cancel pairing.”
☑️ Preparing to connect
Step-by-step guide: how to enable Watch Call through the app
After the preparatory work Let's move on to the main process. Open the installed application on your smartphone. The home screen usually displays a status of "No device" or "Device not connected." Click the add device button or the “+” icon in the corner of the screen.
The application will begin scanning available devices. The name should appear in the list X8 Pro or a combination of letters and numbers. Click on it to pair. A confirmation (pairing) request may appear on the watch screen; the code must match the code on the phone screen. Confirm the action on both devices.
After successful connection, the watch control interface will appear in the application. Here you need to find the section responsible for telephone functions. It may be called Device, Phone or have a handset icon. Inside this menu there should be a switch Sync Contacts (Contact synchronization) and Call Log (Call log). Activate them.
Important point: at this moment a system window requesting permissions will appear on the phone. Android will ask: "Allow the app to access your contacts and call history?" You must click “Allow” for all items. Without this, the watch will not be able to display the names of callers and history.
| Setting stage | Action in the application | Action in the Android system | Result |
|---|---|---|---|
| 1. Search | Click “Add Device” | Enable GPS and Bluetooth | Watch found in the list |
| 2. Pairing | Selecting X8 Pro device | Code confirmation | Device paired |
| 3. Permissions | Enabling Sync Contacts | Clicking “Allow” in the pop-up window | Access to the contact book |
| 4. Test | Dialing a number from the watch face | Automatic answer | Sound comes through the watch |
What to do if the application does not see the watch?
If scanning does not give results, try restarting Bluetooth on phone (turn it off and on). Also make sure your watch is not connected to another phone nearby. Sometimes rebooting the watch itself through the Reset menu helps.
Setting system permissions and power saving
Even after successful synchronization, the function Watch Call may be unstable due to Android security settings. The operating system strives to extend battery life, so it may kill the background process of the watch application. To avoid this, you need to add the application to the exclusion list.
Go to Settings → Applications → [Your watch app] → Battery. Select "No restrictions" or "Do not save battery" mode. This will allow the application to constantly communicate with the watch and instantly transmit a signal about an incoming call. Without this setting, the watch call may sound late or not sound at all.
Also check autorun. On smartphones from Xiaomi, Huawei, Honor and other brands with aggressive optimization, you need to manually allow the application to autorun. Find the “Autostart” section in your phone settings and make sure that the switch opposite the watch application is active.
- 🔋 Allow work in the background for a stable connection.
- 🛡️ Disable energy saving specifically for this application.
- 🚀 Add the application to memory (Recent Apps) and secure it (lock) so that the system does not unload it from RAM.
Particular attention should be paid to microphone permissions. If you want to not only hear your interlocutor, but also talk through your watch, the application must have access to the microphone. Check this in the section Settings → Applications → Permissions → Microphone.
⚠️ Attention: The interface of the “Battery” and “Permissions” menu may differ depending on the version of Android and the manufacturer’s shell (MIUI, OneUI, ColorOS). Look for items that are similar in meaning if the exact names do not match.
Using the calling function in everyday life
When everything is set up, using the function becomes intuitive. When you receive a call, your watch vibrates and the contact's name or phone number appears on the screen. To answer, just press the green handset on the screen or, in some modifications, double-click the side button.
During a call, basic functions are available on the watch screen: muting the microphone, ending the call and, sometimes, volume control. You should speak with your wrist raised closer to your face, since the built-in microphone in the watch X8 Pro has a directional range and is sensitive to ambient noise.
For an outgoing call, open the application menu on the watch (swipe or button) and select the phone icon. You will see a list of recently dialed numbers or Favorites. If synchronization of contacts was successful, you will be able to find the subscriber by letters of the alphabet, although search by letters is not implemented in all firmware versions.
The quality of communication directly depends on the distance to the phone and the presence of interference. Walls, metal structures, and operating microwave ovens can degrade the Bluetooth signal. In such cases, your voice may sound choppy or metallic.
Speak clearly and raise your wrist toward your face. The microphone in the watch is small and located on the body, so it may be difficult to hear you at arm's length.
Solving common problems and malfunctions
Despite the ease of setup, users often encounter problems. The most common one is lack of sound. You see the ringing, the watch vibrates, but the audio comes through the phone. This means that the HFP profile is not activated. Go to your phone's Bluetooth settings, find X8 Pro and click on the gear or information icon. Make sure the Media Sound and Call Sound sliders are turned on.
Another problem is contact desynchronization. Names are not displayed, only numbers. Try turning off contact synchronization in the app on your phone, wait 10 seconds and turn it on again. Sometimes it is necessary to completely remove the application and reinstall it, since the contact database may have become corrupted.
If the watch stops responding to commands, restart both devices. Turn off your phone and watch, turn on your phone first, wait for the system to boot, then turn on your watch. This resets the Bluetooth stack errors.
⚠️ Attention: If after all the manipulations the sound still does not appear, the watch speaker may be damaged or there is a software failure in the firmware. In this case, you may need to flash the device using specialized software.
FAQ: Frequently asked questions
Is it possible to insert a SIM card into the X8 Pro for calls without a phone?
No, in the classic model X8 Pro there is no slot for a SIM card and LTE/3G support. The watch only works as a headset paired with a smartphone. There are Pro Max or Ultra versions with SIM support, but they differ in design.
Why can the interlocutor hear me poorly?
The microphone in a budget watch does not have noise cancellation. If you are in the wind or in a noisy place, the voice will be drowned out. Also make sure that the microphone hole (usually a small hole on the case) is not blocked by a strap or dirt.
Is the X8 Pro compatible with iPhone (iOS)?
Partially. With iOS (iPhone), the watch connects, notifications arrive, but the function Watch Call (talk through the watch) on the iPhone often does not work or is unstable due to limitations of the Apple operating system for third-party Bluetooth devices.
How to increase the speaker volume during a call?
On the watch itself, the speaker (conversation) volume control is often missing or limited. The volume depends on the phone’s media sound level or is fixed at the watch firmware level. Make sure that the volume on your phone is turned up to maximum.
The clock shows “Bluetooth disconnected”, although the phone is nearby. What to do?
Check whether the phone’s Bluetooth module has fallen asleep to save energy. Also try pressing the “Reconnect” or “Refresh” button in your watch app. If that doesn't help, reboot the watch through the menu.
The main idea: Stable operation of Watch Call on the X8 Pro depends not so much on the watch itself, but on the correct settings for permissions and energy saving in Android.
