Modern wearable gadgets have become an integral part of the digital lifestyle, and budget models such as M4 Smart Watchare popular due to their price-to-functionality ratio. However, owners of devices based on Android often encounter difficulties during initial synchronization, since the process requires the installation of specific software, and not just pairing through the standard Bluetooth menu. Successful connection guarantees receiving notifications, activity tracking and health monitoring in real time.
Before you begin setup, it is important to make sure that your equipment is ready for interaction. Smart watch M4 work in pair with smartphones that support Bluetooth 4.0 and above, as well as the operating system Android 4.4 or newer. Errors most often occur at the stage of ignoring the proprietary application, since an attempt to pair exclusively through the phone’s system settings leads to unstable operation or a complete lack of communication.
In this guide, we will analyze in detail each step, from downloading the utility to fine-tuning notifications. You will learn how to correctly enter user data so that the activity tracker works correctly, and what to do if the gadget is not displayed in the list of available devices. Attention: the procedure may vary slightly depending on the firmware version of the watch and the shell of your smartphone.
Preparing devices and checking compatibility
The first stage is the physical preparation of gadgets. Charge M4 smartwatch to at least 50% to avoid shutting down during setup. Make sure that the module is turned on on your smartphone Bluetooth and geolocation (GPS) is activated, as many tracker applications require access to location in order to correctly search for peripheral devices.
Download the required application. For the model M4 the app most often used is WearPro, Fundoo or Yoho Sports (the exact name is indicated in the instructions or on the box). Do not try to find the device in the general list of Bluetooth headsets - this is a key error that causes the phone to see the watch, but cannot complete pairing.
⚠️ Attention: If you have custom Android firmware installed or an aggressive power-saving mode, the system may block the background operation of the watch application.
Check the list of installed updates for your smartphone. Sometimes outdated drivers Bluetooth prevent connection with new revisions of chips in watches. Reboot both devices before starting the procedure - this will clear the network settings cache and eliminate temporary software glitches.
Before downloading the application, disable VPN and proxy servers, as they can block the connection with data synchronization servers.
Installing and configuring a proprietary application
After downloading the installation file from Google Play Market or scan the QR code from the instructions, launch the application. The first time you log in, the system will ask for a number of permissions. It is critically important to provide access to notifications, contacts and geolocation, otherwise the functionality of the watch will be greatly reduced.
Create an account or log in as a guest, if such an option is provided. In the profile section, enter your anthropometric data: height, weight, date of birth and gender. These parameters are necessary for algorithms M4 to accurately calculate calories burned and step length. Without this data, statistics will be approximate and inaccurate.
Inside the application, find a section Devices or icon + to add a new gadget. Click the search button. Unlike system pairing, searching through an app initiates a special handshake protocol that exchanges encryption keys between the phone and the watch.
- 📱 Make sure the watch screen is unlocked and in the active menu during the search.
- 📡 Keep your smartphone and watch no more than 1 meter apart.
- 🔋 Disable power saving mode on your phone during setup.
| Parameter | Requirement | Note |
|---|---|---|
| Android version | 4.4 and higher | Android 8.0+ is recommended |
| Bluetooth | 4.0 LE | Low power consumption is required |
| Phone memory | Min. 100 MB | For data cache and logs |
| Internet | Wi-Fi or 4G | Needed during first synchronization |
☑️ Ready to connect
The pairing process via Bluetooth
When the application finds the device M4 Smart Watch, a request to confirm pairing will appear on the smartphone screen. At the same time, a confirmation code or button OK. Confirm the action on both devices within 30 seconds, otherwise the connection session will expire.
After successful pairing, the clock icon in the application will become active, and the watch face will display the current time synchronized with the phone. Automatic synchronization time occurs every few hours, but you can force it through the app menu. If the time is wrong, check the time zone settings in the application itself.
In some cases, especially on smartphones Xiaomi, Huawei or Samsung, the system may request pairing in the Bluetooth system menu after initiation through the app. If this happens, agree, but do not try to connect manually without the companion app running.
What should you do if the pairing request does not appear?
Sometimes the Bluetooth service freezes. Try clearing the Bluetooth app cache in your phone settings (Settings → Applications → Bluetooth → Storage → Clear cache) and reboot your device.
It is important to understand the difference between a call connection and a data connection. The model M4 often supports two communication channels: one for transmitting telemetry (steps, heart rate), the other for an audio stream (if there is a speaker). Make sure that both device profiles are checked in the Bluetooth settings.
Setting up notifications and health functions
The main value of a smartwatch is instant access to information. In the application, go to the section Notification settings and activate the necessary messengers: WhatsApp, Telegram, Viber or system calls. The watch will vibrate when a message arrives, displaying text on the screen.
For health monitoring to work correctly, the strap must fit tightly to your wrist. Sensor photoplethysmography (PPG), located on the rear panel M4, reads the pulse by passing light through the skin. If the strap is loosely tightened, the sensor will receive interference from external light, resulting in errors in readings or missing data.
⚠️ Attention: The function of measuring blood pressure and blood oxygen levels in budget models is an estimate and cannot be used for medical diagnoses.
Set up activity goals. You can set a daily step goal of 10,000, for example, and the watch will remind you to move if you sit still for a long time. The function Sleep automatically analyzes the rest phases if you wear the watch at night, but for this you need to turn on the corresponding switch in the application.
Solving problems with connection and synchronization
If a watch stopped syncing or the data is not updated, first check the application in the background. The operating system Android tends to “kill” background processes to save energy. Add the watch application to the exclusion list or “white list” of battery optimization.
A common problem is time desynchronization. If the clock shows the wrong time, go to the application settings and find the item Time synchronization. Turn on the automatic update option. In rare cases, a complete reset of the watch to factory settings through the menu of the gadget itself helps (item Reset).
If you cannot find the device, repeat the “forget the device” procedure in the phone’s Bluetooth settings, remove the device from the application, reboot both gadgets and start the process again. Make sure that the watch is not connected to another smartphone within a radius actions.
Path to reset Bluetooth settings (example for pure Android):
Settings → Connected devices → Paired devices → Click on the gear next to M4 → Unpair
Phone manufacturer interfaces may hide the options you need. For example, on MIUI you need to enable application autostart, and on OneUI you need to allow work in sleep mode. Ignoring these settings results in the watch operating autonomously, but not transmitting data to the phone.
Stable operation of the watch depends 90% on the correct energy saving settings of the smartphone, and not on the quality of the watch itself.
Additional features and personalization
Model M4 supports changing watch faces. The app has a cover store where you can download new designs. Select the style you like and click Apply. The image will be transferred to the watch via Bluetooth, which may take from 30 seconds to 2 minutes depending on the file size.
Use the phone search function. If you have lost your smartphone within the apartment, activate the command Find Phone on the watch. The smartphone will start beeping even if it is in silent mode (on some models). This is a handy feature for quickly finding your device.
- ⌚ Set your wrist to lift to turn on the screen (saves battery).
- 🌙 Turn on Do Not Disturb mode at night to prevent the screen from lighting up due to movements during sleep.
- 📸 Use the watch as a remote shutter for smartphone cameras.
Regularly update the watch firmware through the app. Developers are releasing patches that correct heart rate measurement errors and improve connection stability. Checking for updates is usually located in the section About the device or Firmware Upgrade.
⚠️ Attention: Do not interrupt the firmware update process and keep the watch on charge, otherwise the device may turn into a “brick.”
