Samsung Galaxy S27 Ultra may debut ‘Polar ID’ polarized‑light face unlock without IR hardware
Published: November 7, 2025 TL;DR Early test firmware references suggest Samsung is exploring a new facial authentication system called Polar ID for the Galaxy S27 Ultra. The tech reportedly uses polarized light instead of a dedicated IR dot projector, targets ~180 ms unlock times, ties into an ISOCELL Vizion front sensor and a new “BIO‑Fusion Core” secure enclave routine, and is aimed at improving spoof resistance over today’s 2D face unlock. The S27 Ultra itself isn’t expected until early 2027, and Samsung has not confirmed any of this—so treat it as an informed rumor for now. Wccftech+2SamMobile+2 What was leaked
