Modern wearable gadgets are becoming more and more accessible, and the brand Lefun occupies a strong position in the segment of budget devices. However, initial setup often causes difficulties for users, especially when trying to connect the device to the operating system Android. The synchronization process requires not only turning on Bluetooth, but also installing specialized software that acts as an intermediary between the phone and the watch.
In this article we will analyze in detail all the stages pairing, from finding the desired application to the intricacies of setting up notifications. It is important to understand that the standard Bluetooth menu of your smartphone in this case plays a secondary role. The main work of data transfer and time synchronization occurs through proprietary protocols inside proprietary software. Ignoring this rule is the most common mistake of beginners.
The correct sequence of actions guarantees stable operation of the activity tracker, correct display of calls and long battery life. If you have already encountered a situation where the watch is visible in the list of devices, but does not connect, or the application does not find the gadget, then the material below will help resolve these problems. We will look at the nuances of working with different OS versions and watch models.
Preparing the device and selecting an application
The first step before setting up is to fully charge the watch. Devices with a low charge level may not work correctly with the module Bluetooth, which will cause the connection to be broken during the initial handshake. Place the gadget on the magnetic charger for at least 30 minutes, even if the indicator shows the presence of energy.
Next, you need to determine which application is required for your model. The brand Lefun uses several different platforms depending on the year of manufacture and series of the device. Most often these are applications WearPro, Fundoo or Lefun Health. Exact information can be found in the paper instructions supplied with the kit or on the device box.
If the documentation is lost, try scanning the QR code that is usually displayed on the watch screen when you first turn it on or is hidden in the settings menu of the gadget itself. If there is no QR code, go to the official store Google Play and enter the model name in the search. Manufacturers often indicate the name of compatible software in the product description.
⚠️ Attention: Never download applications for controlling your watch from third-party sites or forums. APK files from unverified sources may contain malicious code or be an outdated version that does not support new encryption protocols.
After installing the application, launch it and grant all requested permissions. For trackers and notifications to work correctly, access to geolocation, contacts, call logs, and background work is critical. Without permission to use GPS (even if the watch does not have a navigator), many smartphones running Android 6.0 and higher block the search for Bluetooth devices.
If the application requires access to “Notifications” in Accessibility, be sure to enable this item in the phone settings. Without this, the function of reading messages on the watch will not work.
The pairing process via Bluetooth
Many users make the mistake of trying to connect the watch directly through the Bluetooth system menu of the smartphone. This is the wrong approach for series devices Lefun. First you need to pair within the interface of the installed application. Only after successful communication in the application, the device will appear in the system list as connected.
Open the downloaded application and go to the settings section or user profile. Find the button Add device or Bind Device. At this point, the watch screen may require confirmation of the action. Press the touch button or hold the side key to activate the search mode on the gadget itself.
The application will begin scanning available devices within range. When the name of your watch appears in the list (usually this is a model, for example Lefun L13 or Lefun Watch 2), click on it. The connection process may take from 5 to 15 seconds.
- 📱 Make sure Bluetooth is turned on on your phone and is visible to other devices.
- 📍 Check that location services (GPS) are activated in the notification shade.
- 🔋 The watch must have at least 20% charge for stable operation. connections.
- 🔄 Reboot your phone if searching for a device takes more than 2 minutes.
In some cases, the Android system may ask for a verification code (PIN-code). Typically these are four digits that appear on the clock screen. Enter them in the window that appears on your smartphone. After successful entry, you will see the “Connected” status in the application, and the broken ring icon will disappear on the watch dial or a connection icon will appear.
☑️ Checklist before pairing
Setting up synchronization and notifications
After successful connection, the fine-tuning stage begins. By default, the watch may not display notifications from social networks or instant messengers. To fix this, go to the Notification settings section inside the application. Here you will see a list of all apps installed on your phone.
Activate the switches next to those applications from which you want to receive notifications on your wrist. These can be WhatsApp, Telegram, Viber or system calls and SMS. Remember that the watch only duplicates the notification; It is often impossible to answer a message or take a call (if there is no speaker) with their help.
Also in this section you can set vibration and intervals of reminders about a sedentary lifestyle. The function Sedentary Reminder is useful for office workers. The watch will vibrate after a set period of time, prompting you to get up and stretch.
| Notification type | Operation description | OS requirements |
|---|---|---|
| Incoming call | Displays the number or contact name | Access to call log |
| SMS messages | Shows the text of the message in full | Access to SMS |
| Messengers | Duplicates phone push notification | Access notifications |
| Calendar events | Meeting reminder 15 minutes in advance | Calendar synchronization |
It is important to note that if you clear the notification on phone, it will also disappear from the watch screen. This is due to the fact that the device does not store message history locally, but only broadcasts the current system status.
Solving problems with connection and visibility
The situation when the phone does not see the clock or the connection constantly disappears is one of the most common complaints. Often the reason lies in the aggressive energy saving policy of modern Android shells (MIUI, EMUI, OneUI). The system may "kill" the application's background process, deeming it useless, which results in the connection being lost.
To prevent this, you need to add the clock management application to the battery exceptions. Go to Settings → Battery → Launch applications (the path may differ depending on the phone model). Find your application and allow it to autorun, run in the background and indirectly launch.
⚠️ Attention: On Xiaomi and Huawei phones, you must also pin the application in memory. Open the running tasks menu, find the watch application and pull it down (or press the lock) so that the system does not close it when clearing the memory.
Another cause of problems may be a Bluetooth address conflict. If you've previously connected this watch to another phone, it may try to connect to the old device. Go to the Bluetooth settings of your old phone, find the watch in the list and click Forget device or Cancel pairing.
As a last resort, a full reset of the watch to factory settings will help. Usually this option is located in the clock menu in the Settings → Resetsection. After the reset, you will need to go through the connection procedure again, as if you had just taken the device out of the box.
What to do if the watch connects, but the data is not synchronized?
Try to manually update the data in the application by pulling the screen down. If this doesn't help, uninstall the app, restart your phone, and install it again. Also check if the "Flight" mode is turned on on your phone.
Firmware update and sensor calibration
Manufacturers regularly release software updates to fix bugs and improve sensor accuracy. You can check for a new version in the About the device or Firmware Update inside the application. If an update is available, make sure your watch is charged to more than 50%.
The update process (OTA) occurs automatically. Do not touch your phone or watch during this time. Interrupting the process may cause the device to stop turning on (“bricked”), and it will be extremely difficult to restore it at home.
To improve the accuracy of the pedometer, it is recommended to calibrate it. Walk a known distance (for example, 100 meters) with your phone in your hand, comparing the pedometer readings of your smartphone and your watch. In the application settings, you can sometimes enter the length of your step manually, which will significantly improve the statistics.
The accuracy of heart rate measurement depends on the tightness of the strap to your wrist. If the sensor is not working correctly, try tightening the strap a little tighter or moving the watch 1-2 centimeters above your wrist bone. This will ensure better contact of the optical sensor with the skin.
Stable operation of the watch depends 80% on the correct energy saving settings of the smartphone. If the application is closed by the system, synchronization will not work.
Frequently asked questions and additional features
Users often wonder if it is possible to answer calls directly from the watch. It depends on the specific model Lefun. Low-cost versions only display the caller's number and allow you to reject the call. Models with support for SIM cards or a built-in speaker allow you to have a full conversation.
The question of changing dials is also relevant. Most apps offer a library of built-in designs. Select the style you like and click the install button. The image will be downloaded to the watch's memory, which may take some time depending on the speed of the Bluetooth connection.
Please remember that the watch is not completely waterproof. Even if they are marked IP67 or IP68, it is not recommended to take a hot shower with them or swim in salt water without subsequent rinsing with fresh water. Steam and salt can damage the seals.
Why doesn’t the watch show notifications from WhatsApp?
Make sure that the checkbox next to WhatsApp is enabled in the application settings. Also check if notifications for this messenger are not disabled in the Android settings themselves. Sometimes reinstalling the companion application helps.
How to reset your Lefun watch if it is frozen?
Try holding the side button for 10-15 seconds to force a reboot. If this does not help, put the watch on charge - this often causes a hardware restart. As a last resort, use the reset function in the application.
Is it possible to connect the watch to two phones at the same time?
No, most Lefun models only support connection to one active device. To switch to another phone, you must first turn off the clock in the application on the first device or reset the settings.
Why did the battery consumption on the phone increase after connecting?
Constant data exchange via Bluetooth and running the application in the background consume energy. This is a normal situation. To save money, you can disable the synchronization of unnecessary notifications and reduce the frequency of updating heart rate data.
