A forthcoming Pixel functionality may enhance Face Unlock usability during nighttime or dimly lit conditions. Code discovered in Android 17 QPR3 Beta 1 by Android Authority references a capability named "Face Active Illumination," designed to assist Pixel devices in recognizing facial features when ambient lighting is insufficient. The implementation reportedly includes a brightness adjustment control and options to enable the feature under specific scenarios, such as after designated bedtime hours or when the device is in "Do Not Disturb" mode. No official announcement from Google has been made regarding the feature's rollout timeline or availability.
