Mi Band 4: Pair First – The Connection Problem

Owners of Xiaomi fitness bracelets often face a situation when the device stops syncing with the smartphone, and the intrusive Pair First message appears on the screen. This inscription translates as "First create a pair" and indicates that the bracelet has either severed communication with the phone or lost authorization keys. Instead of the usual display of time or pedometer, the user sees only a call to action, ignoring which makes the tracker useless.

The problem is not only relevant for the Mi Band 4 model, but also occurs on other generations of smart watches from the Chinese manufacturer, which can be caused by a software failure in the Mi Fit application (now Zepp Life), and a banal overflow of Bluetooth module memory in the phone. In this article, we will analyze the algorithms for restoring the functionality of the gadget, starting from simple actions to a complete reset.

Don't panic if your tracker suddenly stops responding. Pair First is a regular data protection situation that requires re-authorization. Restore functionality usually takes no more than 10-15 minutes if you act consistently. It's important to understand that forced pairing without first cleaning old profiles can lead to cyclical failure.

The reasons for the Pair First error on Mi Band 4

Before you start taking action, you need to understand the nature of the error. The Bluetooth Low Energy system used in the Mi Band 4 is sensitive to changes in network configuration. Often, a Pair First message occurs after a smartphone operating system update, when security protocols change and the old encryption keys become invalid.

Another common cause is an application conflict: If the phone has Mi Fit, Zepp Life and third-party utilities like Notify for Mi Band installed simultaneously, they can pull the connection onto themselves, receive conflicting commands and, for security reasons, break the connection, requiring a new binding, and an error can signal battery discharge below a critical level when the communication module is unstable.

Failures in the Bluetooth module of the phone also play a role: a crowded cache of Google Play services or the system Bluetooth stack can block the correct handshake of devices. In such cases, the phone “sees” the bracelet, but can not transmit data for authorization, which leads to the appearance of the Pair First inscription on the tracker display.

• 🔋 Low charge: Bracelet battery is discharged so that the communication module is intermittent.
• 📱 Multiple applications attempt to control one device at the same time.
• 🔄 System Update: Change of security protocols after Android or iOS update.

⚠️ Note: If the Pair First message appears after the bracelet hits the water or hits the water, it may damage the internal contacts.

Basic reboot and Bluetooth verification

The easiest and often most effective way to solve the problem is to reboot both devices in a full cycle, not just to turn off the smartphone screen; you need to restart the operating system completely, which allows you to clear RAM and reset the suspended processes of the Bluetooth service, which could block the connection to the Mi Band 4.

Once you turn on your phone, go to Bluetooth settings. Find your bracelet (usually denoted as Mi Band 4 or Mi Smart Band 4) in the list of previously paired devices. Click on the gear icon or information next to the name and select Forget the device or Unpair. This is a critical step, as old access keys can interfere with the new connection.

Now turn on Bluetooth again and hold the bracelet to the phone. If the tracker screen still has a Pair First, try pressing the touch button (if the model allows) or plugging it into the charger for 1-2 minutes. Sometimes a short power supply restarts the microcontroller bracelet, resetting temporary errors.

Check to see if the phone is power-saving mode for the Zepp Life app. Android often kills the tracker background processes to save energy, causing communication to break and requiring re-pairing. Allow the app to run in the background without restrictions.

Resetting the bracelet to factory settings

If simple methods don’t work, a more radical approach is needed — resetting the Mi Band 4 to factory settings — which will remove all the accumulated data about steps and dreams that haven’t been synchronized yet, but it’s needed to fix firmware bugs, a feature often hidden in deep menus on the wristband itself, or unavailable if the device is getting stuck on the Pair First screen.

To reset via the tracker menu itself (if available): swipe across the screen to the left or right to find the "Additional" section (an icon with a tether or gear). Find the "Reset" item and confirm the action. The bracelet vibrates and reboots, after which the animation of the greeting and the rest of the screen should appear. QR-new-conjugation.

However, if the menu is unavailable due to an error, use the charger. Connect the Mi Band 4 to charge and wait for the battery icon to appear. Immediately after that, before the device has gone into sleep, try to find it in the application. In some cases, connecting to the power source will force the detection mode.

Remember, once reset, the bracelet becomes a blank slate. You have to reconfigure the language, the time format (12/24 hours) and raise your wrists to activate the screen. All these settings are stored in the device's memory and erased when you completely reset, unlike the activity history that remains in the cloud akka.

The application Zepp Life (Mi Fit)

A key element of the ecosystem is the intermediary app. At the moment, the main application for the Mi Band 4 is Zepp Life (formerly Mi Fit). If you have an old app installed, it is recommended to update it to the latest version through Google Play or the App Store. Older versions may not properly handle requests for reconnection of new batches of devices.

Inside the app, delete the bracelet profile. Go to Profile (bottom right), select My Devices (or just the name of your bracelet). Scroll down and hit the red Unbind button. Only then you can try to add the device again through the + button in your profile.

When you add again, make sure you choose the right model. Mi Band 4 has several modifications, including the NFC version. If you choose the wrong model, the search process can go endlessly or end in error immediately after detection. Carefully read the names: Mi Band 4 NFC and Mi Band 4 (without NFC) are different connection profiles.

⚠️ Note: Do not try to connect the bracelet directly through the Bluetooth settings of the phone, ignoring the application. Mi Band 4 will not transmit data to the application if (pairing) is not made through the official Zepp Life interface.

Solving Access Rights and Geolocation Problems

Modern versions of Android (starting with 6.0 and up) require geolocation to enable Bluetooth scanners, a system restriction Google has introduced for privacy. MAC-Bluetooth addresses can be used to determine the user's location. GPS It is turned off, the app simply won’t see the bracelet or will not be able to complete the Pair First process.

Also, permissions are critical for the app itself. Go to Settings → Applications → Zepp Life → Permissions. Make sure you are allowed: location (GPS), Bluetooth, notifications and, preferably, a phone book (to display callers’ names). Without the right to geolocate, the device search process will give an error or endlessly rotate the boot indicator.

Some smartphones (Xiaomi, Huawei, Samsung) have aggressive power saving settings, you need to go to the battery settings and set the "No Limits" or "Start Automatic" mode for the Zepp Life application, otherwise the system will block background synchronization, and the bracelet will constantly require re-pairing.

Complete reinstallation of the application and cleaning the cache

When nothing works, the "nuclear option" is the complete reinstallation of the software on the phone. First, uninstall the Zepp Life app (or Mi Fit.) Then go to Settings → Apps → Show system processes (if available), find "Bluetooth" and click "Clear Cache" and "Clean Data." This will return the Bluetooth module to its original state.

Once you clear the Bluetooth cache, reboot your phone. Download the latest version of the app from the official store (Play Market or App Store). When you first start, re-register or log in to your Mi Account. Important: don't try to search for the bracelet right away, first make sure that the app doesn't have old device profiles.

Now you can initiate the search process. Click on the plus, select Mi Band 4 and wait for the vibration. The bracelet screen will show a vibration signal and possibly a phone icon. Click on the touch area of the bracelet to confirm. If it went well, the Pair First will change to the boot screen or the main dial.

• 🗑️ Delete: Completely remove the Zepp Life app from your device.
• 🧹 Cleanup: Reset data and cache of the Bluetooth system service.
• 📥 Installation: Install the latest version of the application from a trusted source.
• 🔗 Bundle: Creating a new pair from scratch through the application interface.
