Samsung has yet to unveil its Galaxy S26 lineup. However, its Galaxy S27 series, which won't come out until early 2027, has already begun attracting rumors and tidbits, with the latest one focusing on the S27 Ultra's novel face authentication mechanism.
Samsung Galaxy S27 Ultra might sport a new "polarized-light" face authentication mechanism, sans dedicated infrared (IR) hardware
A tipster, who goes by the username @SPYGO19726 on X, has just posted that Galaxy S27 Ultra's early test firmware references "Polar ID v1.0" under the biometric security framework, with the accompanying internal logs describing the term as a "polarized-light authentication system."
If accurate, this appears to be Samsung's first serious pivot towards a face authentication mechanism that does not utilize hefty infrared (IR) hardware, which allows for detailed 3D scans of the face.
The tipster notes that the referenced module appears "tied to the front ISOCELL Vizion sensor and a new secure enclave routine labeled BIO-Fusion Core."
Critically, the new face authentication mechanism boasts an unlock latency of around 180ms and offers improved resistance to spoofing vs. the standard face unlock available on the Galaxy S-series, which uses a simple 2D image scan from the front-facing selfie camera.
Do note that a recent leak from the same tipster has quickly devolved into a mudslinging fest with another reputed tipster, Ice Universe.
As we detailed in a recent post, SPYGO19726 disclosed earlier this week the Exynos 2600's camera-related capabilities and Samsung's selective utilization of those abilities in the Galaxy S26 series.
As far as specific claims were concerned, SPYGO19726 tipped that the 3x telephoto lens on the upcoming Galaxy S26 Ultra would sport an upgraded 12-megapixel resolution. This was fiercely contested by Ice Universe, who declared that the Samsung Galaxy S26 Ultra will feature a 1/3.94-inch, 10-megapixel 3x telephoto lens, which would be smaller than the 1/3.52-inch, 10-megapixel 3x telephoto lens on the S25 Ultra.
