Turn Attention Aware features on or off
Even if you don’t enroll in Face ID, the TrueDepth camera on iPhone X or later intelligently activates to support attention aware features. For example,
- When you’re looking at your phone, your display will not dim until you stop looking at your device.
- If you're looking at your device, it will lower the volume sound of your alerts.
If you don’t want to use these features, go to Settings > Face ID & Passcode and turn off Attention Aware Features.
