To enable the proximity sensor during a call on the latest iPhone models, such as the iPhone 14, iPhone 14 Pro, or iPhone 14 Plus running iOS 16, simply follow these steps:
1. During an active call, ensure that the call screen is visible on your device.
2. Position your iPhone near your ear as you would typically do for making a call.
3. The proximity sensor, which is located near the front-facing camera at the top of your iPhone's screen, should automatically detect your proximity and turn off the display to prevent accidental taps or button presses.
4. This is done to conserve power and minimize unintended actions while the device is in close proximity to your face.
5. As soon as you move your iPhone away from your ear, the proximity sensor detects the change and turns on the display again, allowing you to interact with the call controls.
By enabling the proximity sensor during a call, you can prevent unintentional touch inputs on your iPhone's screen during conversations, which enhances the user experience and avoids accidental call drops or mishaps.
