Samsung Galaxy S27 Ultra may debut ‘Polar ID’ polarized‑light face unlock without IR hardware
Test firmware for Samsung’s upcoming Galaxy S27 Ultra reportedly references a new “Polar ID” facial authentication system using polarized light and an ISOCELL Vizion front sensor. Internal logs suggest the system aims for 180 ms unlock times and improved spoof resistance, tied to a new BIO-Fusion Core secure enclave. Samsung has not confirmed the feature. The S27 Ultra is expected in early 2027.
