1. Watch answer calls: When the phone is normally connected to the watch, the incoming call reminder of the phone will be synchronized and prompted in the watch, and the watch side can answer/reject the call by taping the answer button or hanging up button (synchronized operation of the phone);
2. Watch dialing: When the cell phone is normally connected to the watch, the phone call can be initiated through the frequently used contacts, emergency contacts, call records and missed call reminders (cell phone synchronization initiates the dialing);
3. Calls from cell phone to watch: When the cell phone is normally connected to the watch, calls being made on the cell phone side can be made using the watch by switching the calling device to the watch.
