Solution: bracelet not found or connected
The fact that the phone doesn't see the fitness bracelet is one of the most common. Often the reason is that the device has already been paired with another phone or the smartphone itself, but the connection was broken incorrectly. The Bluetooth cache may contain erroneous device profile data.
To solve the problem, do a full Bluetooth reset. Go to your phone's Bluetooth settings, find your M4 (or a name like MI Band 4, M4 Smart) in the list of previously connected devices, and click "Forget the device" or "Cancel pairing." After that, reboot the smartphone.
If that doesn't work, reset the bracelet to the factory settings, usually through the tracker's menu: find Settings or Reset and confirm the action, and after rebooting, the bracelet goes into search mode, and it can be re-tied through the app.
- 📱 Reboot modules: Turn on and off flight mode for 10 seconds to restart the phone's radio modules.

The accuracy of heart rate and sleep measurements depends on the density of the strap to the wrist, and a weakened strap causes data loss and false sensor readings.
You also need to set activity targets. Set realistic goals in steps like 8,000 or 10,000 a day to motivate yourself. The app will vibrate when you reach the goal, which is a great psychological stimulus. Sleep monitoring should be enabled in automatic mode so you don't forget to manually activate it before resting.
Updating the firmware and maintaining the device
Manufacturers regularly release software updates to improve stability and add new dials. When you first connect, the application usually offers to update the firmware. You are advised to agree, as new versions often correct synchronization errors and improve the performance of sensors.
The Firmware Update requires that the bracelet be near the phone and be charged at least 30%. Do not turn off the phone screen or turn off the app while booting, as interrupting the process can cause the device to break down. The entire process takes 2 to 5 minutes.
To extend the life of the battery and screen, follow simple maintenance rules: wipe the body and strap with a dry soft cloth after workouts to remove sweat that can cause charging contacts to corrosion. Avoid shampoos and soaps hitting sensors, as chemicals can damage the protective coating.

- 🧼 Cleaning: Use soft soap and water to clean the strap, but dry thoroughly before putting on.
- 🔌 Contacts: Regularly check the charging contacts on the back for oxidation.
