Apple is working to reduce the size of the Dynamic Island on iPhone 18, but the limits of Face ID hardware continue to dictate how far it can go.
The company is testing a smaller Dynamic Island design for a future iPhone Pro, based on a new supply chain leak. The effort centers on moving more Face ID hardware under the display without hurting security or usability.
Chinese leaker Digital Chat Station said in an April 9 Weibo post that Apple is running A/B tests on two front-panel designs. One keeps the current layout, while the other shrinks the cutout by placing part of Face ID beneath the screen.
The claim lines up with Apple's long-term display roadmap, but it doesn't confirm a shipping product. Apple introduced the Dynamic Island with iPhone 14 Pro on September 7, 2022.
The company said the redesigned TrueDepth camera reduced how much display space the sensors used. Apple also framed it as a blend of hardware and software for alerts, activities, and Face ID authentication.
Why a smaller Dynamic Island is harder than it sounds
Shrinking the Dynamic Island isn't just about looks. Face ID depends on Apple's TrueDepth system, which projects and analyzes thousands of invisible dots. It captures an infrared image and compares the data in the Secure Enclave to authenticate users.
Apple's cautious approach to under-display camera systems is understandable. These systems have been available on Android phones for years, but they often come with a trade-off in image quality.
Early versions of these cameras produce results that are clearly inferior to those from traditional camera cutouts. Apple's challenge is more complex than simply concealing a selfie camera.
While a front camera can afford to be a bit softer if the rest of the phone excels, Face ID is crucial for iPhone security. It plays a vital role in payments, app logins, and system authentication.
A design that prioritizes aesthetics over the speed and consistency of Face ID recognition would be a poor decision for Apple. Ultimately, Apple must balance a sleek look with the essential functionality of its devices.
What the rumor likely means for Apple's roadmap
The most likely explanation for the leak is that Apple is planning a partial under-display Face ID for the iPhone 18 Pro models. Previous rumors claimed that some components of the Face ID system would be hidden beneath the display, while others would still be visible.
Apple is known for its stepwise transitions. For example, it moved from the notch to the Dynamic Island instead of immediately adopting an invisible sensor array.
Similarly, a smaller cutout would likely follow a gradual reduction pattern rather than a risky redesign. Apple prefers to wait until a component is truly ready to blend seamlessly into the product, not just ready for a demonstration.
When it comes to Apple's supply chain, it's always good to be a bit skeptical. A/B testing is a regular part of their hardware development process, particularly for things like display stacks, sensor placements, and manufacturing methods.
Cutaway of the iPhone 14 Pro Dynamic Island
Suppliers often get their hands on prototypes that never make it to the final product stage. This leak is interesting because it hints that Apple is still figuring out how much they can shrink the front cutout.
However, it doesn't necessarily mean they've cracked the tougher engineering challenges yet. So, while it's exciting, we should take it with a grain of salt.
A smaller Dynamic Island could still be significant if Apple manages to make it work. Visual changes are one of the simplest ways to indicate a new iPhone generation, even in a mature market.
However, a reduced cutout alone probably won't drive an upgrade cycle by itself. To truly make it a selling point, Apple would need to combine this cleaner design with more substantial improvements in the camera, chip, or Apple Intelligence.
Digital Chat Station's leak suggests Apple hasn't abandoned that goal. The person behind the account has a mixed track record, with some accurate calls on camera and display details but less consistency than established analysts.
