In this case, please check whether the ringtone in the setting menu of the watch or the local music on the watch plays normally to confirm the normal function of the speaker. If the Bluetooth is disconnected or unstable during the call with the watch, the call will be transferred to the mobile phone. If there is no sound in the watch, please confirm whether the call is automatically switched to the mobile phone.
