Apple iPhone 20th Anniversary All-Screen Test Begins With iPhone 18 Pro 2026

Apple is reportedly using the iPhone 18 Pro and iPhone Duo as test beds for an all-screen iPhone 20th anniversary model, according to recent leaks. The company is said to be experimenting with design elements that will culminate in a special edition iPhone in 2027, marking two decades since the original iPhone launched.

The rumor suggests that Apple plans to release the iPhone 19 next year and then a commemorative iPhone XX in 2027. This strategy mirrors the 10th-anniversary approach when Apple launched the iPhone 8 and iPhone X simultaneously. The iPhone X introduced Face ID and an edge-to-edge display, setting a new direction for the company.

Why the iPhone 20th Anniversary Matters

The iPhone 20th anniversary is more than just a milestone; it represents a potential turning point in Apple's design philosophy. According to leaks, the iPhone XX will be a completely glass-built device with minimal metal and a completely clean front. This would be a significant departure from current models, which still rely on metal frames and have a visible camera cutout.

This aspirational design could redefine what users expect from a premium smartphone. It's not just about specifications but about setting a new standard for aesthetics and functionality. The iPhone X did exactly that by removing the home button and introducing gestures, and the iPhone XX could do the same by eliminating the notch entirely.

How the iPhone 18 Pro and iPhone Duo Fit In

To achieve the all-screen design, Apple is reportedly using the iPhone 18 Pro and iPhone Duo as testing grounds. These devices are expected to feature under-display camera technology and other innovations that will eventually make their way into the anniversary model. The iPhone Duo, in particular, is rumored to be a foldable device, which could provide valuable insights into flexible display technology.

The iPhone 18 Pro might introduce a smaller notch or a different sensor arrangement, serving as a stepping stone toward a completely notch-free design. By iterating on these models, Apple can refine the technology and ensure reliability before the big launch.

The Evolution from Notch to All-Screen

The notch was first introduced with the iPhone X in 2017 as a necessary compromise to house the TrueDepth camera system for Face ID. While Android manufacturers quickly moved to smaller holes and under-display cameras, Apple stuck with the notch for several generations before introducing the Dynamic Island with the iPhone 14 Pro in 2022.

The Dynamic Island is a software-driven feature that expands and contracts to show alerts and activities, effectively turning the cutout into a functional element. However, it's still a compromise. The ultimate goal is a completely uninterrupted display, which requires hiding the front-facing camera and sensors beneath the screen.

Challenges of an All-Screen iPhone

Creating a truly all-screen iPhone involves several technical hurdles. Under-display cameras currently struggle with image quality because the pixels above the lens reduce light transmission. Apple would need to develop a solution that maintains the high standards of its front-facing camera, which is crucial for Face ID and selfies.

Additionally, the glass body rumored for the iPhone XX would need to be durable and support wireless charging. Apple has been using glass backs since the iPhone 8, but a full-glass design would require advancements in materials to prevent cracking and scratches.

• Under-display camera: Hiding the front camera without sacrificing photo quality.
• Glass body: A durable all-glass design that supports wireless charging.
• Sensor integration: Embedding Face ID and other sensors beneath the display.
• Manufacturing yield: Ensuring mass production is feasible and cost-effective.
• Battery and thermal management: Fitting components into a slimmer chassis without overheating.

What to Expect from the iPhone 18 Pro and iPhone Duo

If the leaks are accurate, the iPhone 18 Pro will likely showcase incremental improvements that hint at the future design. We might see a smaller camera cutout or improved under-display technology. The iPhone Duo, on the other hand, could be Apple's first foldable iPhone, testing flexible display and hinge mechanisms.

Both devices are expected to launch before the 20th-anniversary model, giving Apple time to gather data and refine the technology. The iPhone 18 Pro is rumored to arrive in 2026, while the iPhone Duo might also launch around the same time or later.

How This Affects Buyers and the Market

For consumers, the iPhone 20th anniversary model could be a compelling upgrade, especially for those who value design. However, it's likely to come at a premium price, similar to the iPhone X. The iPhone 18 Pro and iPhone Duo will serve as more affordable options with some of the same innovations. The longer history behind the story is traced in iPhone 20th Anniversary: What We Know About Apple's Special Edition.

For the market, Apple's move toward an all-screen design could pressure Android manufacturers to innovate further. Samsung, for example, has already been experimenting with under-display cameras, but Apple's adoption could accelerate the trend. The iPhone XX might also influence the development of foldable phones if the iPhone Duo proves successful.
