Dark grains of uncertainty loom over the iPhone 18 Pro: under-display Face ID is on the horizon, but the path to it is densely technical and controversial. In short, Apple aims to move Face ID beneath the display, not just shuffle parts around. Multiple supply-chain sources confirm active testing of under-display 3D facial recognition for the iPhone 18 Pro models, with engineers tackling how infrared light can pass through display areas without distorting image quality. The challenge isn’t only optical; it involves carefully removing subpixels in a way that users won’t notice, as suggested by patent filings.
What makes this so hard is the optics. Current prototypes rely on metalenses—ultra-thin flat lenses that shape light via surface etchings rather than traditional curved glass. These metalenses help infrared sensors function beneath active OLED pixels, avoiding the interference that plagues conventional lenses. Yet these advances introduce new concerns: optical interference, higher power consumption, and manufacturing complexity, all while trying to preserve Face ID’s rock-solid reliability.
Face ID isn’t a single gadget; it’s an ecosystem. A dot projector floods the face with thousands of invisible infrared points, and a suite of sensors reads the reflected pattern to map facial geometry. The goal is to keep Face ID’s precision (about 1 in a million for false positives) and its anti-spoofing strength (roughly 1 in 50,000 against hacks) even when the sensors sit behind a display. To hit those marks, Apple must ensure fast unlock speeds (millisecond-scale), robust performance under different lighting, and a resilient defense against spoofing attempts using photos, masks, or other tricks.
Manufacturing adds another layer of pressure. Matching the current performance and security levels means solving substantial engineering hurdles, including reliable operation through a display stack, consistent performance across lighting conditions, and scalable, high-quality production. The result is a delicate balance: keep the same user experience and security, but with the sensing hardware protected behind screen material.
What this means for Dynamic Island
Shifting Face ID under the display would alter iPhone design language at a fundamental level. Today, Face ID components nestle inside Dynamic Island. Hiding them under the screen could allow a single, smaller pinhole selfie camera while preserving the familiar Dynamic Island-style software interactions at the top of the display. In other words, hardware constraints could give way to a cleaner front face while software continues to orchestrate notifications and live activities—an approach that echoes trends seen in flagship Android devices.
Beyond hardware, Apple appears to be planning a broader reimagining of Dynamic Island itself. Leaks describe a “significant evolution” that makes Dynamic Island a core, enduring interface feature—more than just a hardware necessity—supporting contextual notifications, live activity, and cross-app workflows.
Even with under-display Face ID, the Dynamic Island may persist as a software layer, gradually shrinking the visible hardware footprint while expanding user interactions. This mirrors Apple’s history of evolving features rather than erasing them, much like the transition from physical home buttons to gesture navigation while maintaining familiar cues.
The iPhone 18 Pro is expected to debut with a much smaller physical cutout for the selfie camera, paired with Dynamic Island-style interactions across the top portion of the display. The outcome would be a cleaner hardware look without sacrificing the software-driven experience developers have already optimized for.
Timeline and reality checks
The road to under-display Face ID has faced repeated schedule shifts, underscoring the depth of the technical obstacles. Early predictions pegged the feature for the iPhone 17 Pro, but industry voices shifted that expectation to 2026, with others suggesting a window of 2026–2027. These delays reflect distinct hurdles: optical interference, power efficiency, supply-chain readiness, and tight quality control to meet Apple’s standards.
Encouraging signals point toward 2026 becoming feasible. Suppliers have publicly committed to under-panel Face ID materials shipping in 2026, a strong indicator that production planning has moved beyond prototypes. Analysts also anticipate cost reductions that would enable mass production and note that OLED advances are key enablers—since the display stack must support under-display sensing without inflating the price beyond a tolerable premium.
Ecosystem-wide implications
Under-display Face ID isn’t just a feature bump—it's part of a larger roadmap. Apple is testing related concepts in a foldable iPad Pro prototype with an 18.8-inch display, suggesting a cross-device approach to authentication improvements that could ripple through iPhones, iPads, and Macs. In practice, this could mean seamless authentication for content creation workflows, smoother large-screen multitasking, and deeper integration with upcoming spatial computing.
Apple’s method is deliberate and measured, prioritizing quality over speed. While Android devices have experimented with under-display cameras, real-world performance often lags behind expectations due to image quality and pixel-visibility trade-offs. Apple’s emphasis on preserving the existing 99.9% Face ID accuracy and sub-second unlock speeds through a display layer signals a careful, premium approach.
A broader, all-display future?
Looking ahead, the under-display Face ID breakthrough could be a stepping stone toward a truly seamless iPhone. Analysts forecast a future where both Face ID and the front camera reside under the screen, erasing visible cutouts and delivering uninterrupted content, akin to the long-envisioned all-screen design. The timing aligns intriguingly with the iPhone’s 20th anniversary, making the moment feel like a symbolic milestone in device evolution.
If realized, this technology would extend beyond aesthetics. Expect more usable screen real estate for immersive experiences, smoother video playback, and more seamless AR interactions, as Apple moves toward a fully integrated, uninterrupted display experience.
Bottom line: a measured leap toward seamless authentication
The iPhone 18 Pro’s under-display Face ID represents a strategic, foundational step in Apple’s broader device ecosystem ambitions. The path forward will likely involve gradual, thoughtful enhancements—balancing top-tier security, fast performance, and reliable operation across lighting and scenarios—rather than a rushed rollout. If successful, this move could redefine how authentication integrates with the entire Apple lineup, making the user experience feel more natural and less dependent on visible hardware while inviting discussion on whether the next leap should go further and be fully unobtrusive. Do you think under-display Face ID will change how you interact with your devices, or will it raise new concerns about reliability and privacy in daily use?
