There are the following reasons:
The current mobile phone cannot be connected back, the old mobile phone has unbound the device, and the new mobile phone has not synchronized the account, so the device cannot be connected back;
Confirm which interface the content displayed on the band screen is on. If it is on the QR code interface or language selection interface, go to the Mi Fitness App on your mobile phone. Unpair this device and re-scan for pairing;
Confirm whether the Bluetooth icon on the band is always on. If it is always on, use "Find Phone" to confirm whether it is connected to the current phone. If not, unpair the device on the App and use the current phone to repair the band.
If there is no such device on the Mi Fitness App device management page of the old mobile phone, it means that the old mobile phone has unbound this device, and the new mobile phone will not display the band after logging in to the same account for synchronization; if the band is on the QR code interface or language selection interface, Rescan pairing;
Two mobile phones with the same Mi account in the APP are connected to the band. After the band is restored to factory settings, use the new mobile phone to re-pair and turn off the Bluetooth of the old mobile phone. If the new mobile phone cannot be connected, it may be that the new mobile phone has not automatically pulled the new login and pairing information.
suggestion:
Please try to avoid logging into multiple mobile phones with one account;
If you are unable to connect back, please turn off the Bluetooth function of other devices logged into the account and try again;
Please keep the network status in good condition, clear the app and reopen it to trigger the cloud to re-issue login and pairing information to ensure that the band can be reconnected.
