Google Tests Pixel Face Unlock Brightness Boost in Android 17 QPR3 Beta 2

Q: Will Google's new screen-brightening trick make Pixel Face Unlock as reliable in the dark as Apple's Face ID?

No. Google’s screen-brightening feature should make Pixel Face Unlock more usable in dark rooms, but it is unlikely to match Apple’s Face ID for dark-condition reliability. The key reason is hardware. Apple’s Face ID uses a dedicated TrueDepth system with infrared illumination, an infrared camera, and depth mapping, so it is designed to work in total darkness without relying on visible light. Google’s reported Pixel feature appears to use the screen itself as a light source, helping the standard front camera see your face better. That can improve performance, but it is still a software-assisted workaround for a camera-based system. The leaked Android 17 QPR3 Beta 2 strings suggest Google knows the tradeoff. Options such as “Reliable” versus “Comfortable,” along with controls for Bedtime mode, Do Not Disturb, and driving, imply brighter light may improve recognition but could also be unpleasant, especially in a dark bedroom. That is very different from Apple’s invisible infrared approach. Pixel Face Unlock on Pixel 8 and newer is already strong enough for banking apps and password managers, which means security is not the main issue here. The weakness has been low-light usability. This feature could reduce failed unlocks and make Pixels noticeably better at night. But unless Google adds dedicated infrared depth-sensing hardware again, as it did on the Pixel 4, Pixel Face Unlock is still unlikely to be as seamless or as consistently reliable in darkness as Apple’s Face ID.

Android 17 QPR3 Beta 2 includes a new “Brighten screen in low light” option that would raise Pixel screen brightness so Face Unlock can work in dim rooms.
Pixel 8 and newer phones use camera-based Face Unlock strong enough for banking and password-manager apps, but the feature currently struggles once ambient light drops.
Code strings point to adjustable brightness modes such as “Reliable” and “Comfortable,” plus controls for complete darkness and limits on how bright the screen can get.
The feature also appears to account for Bedtime mode, Do Not Disturb and driving detection, while temporarily affecting accessibility settings such as Extra Dim, color inversion and reduced animations.
Google has not said when the option will ship, but the beta discovery suggests the company is trying a simple software fix instead of new Face Unlock hardware.
