Samsung Rumored to Test Polarized-Light 'Polar ID' Face Unlock for Galaxy S27 Ultra

Early firmware mentions come from a little-known leaker, leaving the feature unconfirmed well ahead of the S27 Ultra's launch.

Overview

Multiple outlets report early test firmware references to “Polar ID” for the S27 Ultra, described as a polarized-light face authentication system.
The rumored setup is tied to Samsung’s front ISOCELL Vizion sensor and a new secure enclave routine labeled “BIO-Fusion Core.”
The leak claims unlock latency of about 180 milliseconds with improved spoofing resistance compared with current implementations.
Reports suggest the approach could lessen reliance on infrared hardware and may help recognition in challenging lighting or with masks and sunglasses.
Coverage urges caution because the claims stem from a single, little-known source and the S27 Ultra remains many months from release, so plans could change or be dropped.
