If you have an iPhone or iPad with Face ID, you can enable or disable the “Attention” setting to enable or disable devices. In the “Attention!” Functions, an iPhone or iPad camera is used to check whether you are looking at the device before dimming the screen or reducing the volume of alerts on the device.
For example, if you have the Attention features enabled, you may notice that the volume of the iPhone XS, XR, X call is low when you pick up the phone or look at it, and this happens automatically. If you do not want this to happen, you can disable this feature. Similarly, if you previously disabled this feature, you can re-enable face recognition features in Face ID to re-enable these features.
How to enable or disable features that require attention on the iPhone and iPad
Open the Settings app in iOS
Go to “General” and then go to “Accessibility”
Click on “Face Id and Attention”
Toggle the “Functions with Attention” setting to ON to enable this feature, or to OFF to disable it.
The description below this particular attention parameter Face ID looks like this:
“The iPhone / iPad will check attention before dimming the display and lowering the warning volume”
As mentioned earlier, one of the most common examples of users noticing this feature is if they have an iPhone with a Face ID, and they notice that the volume of the call decreases, seemingly from nowhere. Similarly, many iPad users may notice this feature if they find that their screen doesn’t dim or turn off automatically, as expected, because they are looking at the device.
You can choose any setting for this function, so if you like it, leave it turned on, and if not, turn it off. It is easy to change at any time.
The default setting on iPhone and iPad models equipped with Face ID is to enable Attention Aware features, and these features work even if you don’t use Face ID on your device to unlock and authenticate your iPhone or iPad.
