Why don't you hang up on the phone with iPhone 7 Plus?

Because the word "Call Hang Up" is not set in the factory settings of iPhone7Plus.

1. When Apple doesn't answer the phone and wants to hang up, you can directly press the "power" button on the top of the iPhone to achieve the effect of mute the ringtone. Press the power button twice in a row to hang up.

2. The second way for Apple to hang up is to try to click the "Remind me" option, and then click the "1 hour later" option.

3. The third way for Apple's mobile phone to hang up is to click the "Information" option and select a suitable short message. Then the system will hang up the phone and automatically send the selected SMS to the hung-up mobile phone number for us. That's all.
