How to mute the Apple 13 custom ringtone after it rings twice?

The advantage of turning on Apple's gaze sensing function is that when the iPhone receives an incoming call, it will turn down the volume and vibration intensity of the ringtone at a glance, because at this time, the device will think that you already know that there is an incoming call, and there is no need for a larger ringtone to prompt.

First, turn on the phone. We can find the "Settings" icon on the phone desktop and click it to enter the settings page. Then, in the settings page, we can find the "Accessibility" option on the page and click it for the next operation. Find the "Face ID and Gaze" option on the interface, and click this option to enter the next step. Find the "Gaze Perception Function" option and click Open.
