If your Xiaomi Smart Band is not showing incoming call alerts, please refer to the following troubleshooting methods:
1. Please ensure the Bluetooth calls function is enabled. Please open the Mi Fitness App >> [Device] >> [Notifications and calls] >> [Incoming calls].
2. Please check whether the "Notify only for calls from contacts" option is turned on in the band's incoming call settings, because if this is enabled, calls from unknown numbers will not be alerted.
3. Please verify that the band and phone are still properly connected via Bluetooth. Please ensure that the phone's Bluetooth is functioning normally, as calls will not be alerted if Bluetooth is not maintaining a stable connection.
4. Please ensure the band is not in Do Not Disturb or Sleep mode, which would silence or suppress incoming call alerts during the set period.
5. Ensure the app has been granted sufficient permissions for incoming calls and background operation to push incoming call notifications to the smart band.
6. Please ensure that the mobile phone itself can receive and display incoming calls.
If the problem persists, it is recommended to contact after-sales service.
