The Galaxy S26 Ultra hasn't even been released yet, but the tech community has already started talking about the Galaxy S27 Ultra. And this time, all eyes are on a much-anticipated change: a major upgrade to the facial recognition system.

According to leaker @SPYGO19726 on the social network X, Samsung is testing a new technology called "Polar ID v1.0", which promises to bring a big step forward in biometric security. Specifically, Polar ID can go far beyond the traditional 2D scanning method currently used on Galaxy lines, which only relies on the selfie camera for facial recognition.

Leaked information said that Polar ID was discovered in early testing software of the Galaxy S27 Ultra, part of Samsung's biometric security framework. This technology is described as a polarized light authentication system, combined with the ISOCELL Vizion front sensor and a separate security core called BIO-Fusion Core.

If true, it would be a huge leap forward from current infrared recognition technology. Instead of projecting IR dots to create a facial map, Polar ID would use polarized light patterns to “read” the user’s unique skin texture, minimizing the possibility of being fooled by photos or 3D masks.

The source also revealed that Samsung is aiming for an unlock speed of around 180 milliseconds, fast enough to compete with today’s leading biometric systems. However, this is still just the initial testing phase and the Galaxy S27 Ultra is still at least a year away, so Samsung will likely continue to refine the hardware before finalizing the final solution.
