The notch may finally be running out of excuses.

Metalenz says its Polar ID face-scanning technology can work even when the camera sits beneath the display, a claim that strikes at one of the most stubborn design compromises in modern smartphones. If the system performs as described, device makers could keep secure facial authentication while stripping away one of the most visible pieces of front-facing hardware. That would mark a meaningful shift for an industry that has spent years chasing truly uninterrupted screens.

Key Facts

  • Metalenz says its Polar ID face-scanning system works with the camera hidden under the display.
  • The development targets a major smartphone design problem: visible front-facing authentication hardware.
  • Reports indicate the approach could preserve face authentication while reducing screen cutouts.
  • The announcement points to potential applications in future consumer devices, though rollout details remain unclear.

The significance goes beyond aesthetics. Face-scanning systems demand reliable sensing, and under-display components have often struggled when screen layers interfere with light and image quality. Metalenz appears to argue that Polar ID can get around that barrier, opening a path for phone makers that want both cleaner industrial design and advanced biometric security. The appeal is obvious: more screen, fewer distractions, and no need to sacrifice a feature users already rely on.

If Metalenz delivers at scale, the next leap in phone design may come from the sensors you can’t see.

The announcement also lands in a broader push to make core device technology disappear from view. Manufacturers have already shrunk bezels, tucked fingerprint readers under glass, and experimented with under-display cameras, often with mixed results. Metalenz now positions face authentication as the next frontier. Sources suggest the real test will not come in a demo, but in mass-market performance across different lighting conditions, display types, and price tiers.

What happens next matters because smartphone design changes rarely stay cosmetic for long. If under-display face scanning proves dependable, it could influence how companies build premium handsets, how they balance security with design, and what users begin to expect from the front of every screen. For now, Metalenz has put a provocative idea on the table: the best way to improve Face ID may be to make it disappear.
