Apple is reportedly doubling down on a revolutionary screen technology to eliminate the dreaded hinge crease found on rival foldable phones. Leaks suggest the tech giant is testing varied glass thickness to ensure durability while firmly targeting a late 2026 release date.
The smartphone industry has been waiting years for Apple to enter the foldable market. New reports indicate that the company is refusing to launch a device until the screen surface is visually perfect.
Innovative Glass Technology To Solve The Crease
The biggest complaint regarding current foldable smartphones is the visible line where the screen bends.
A new leak from the reliable tipster Digital Chat Station on Weibo indicates Apple is testing a solution called Ultra-Thin Flexible Glass (UFG). This is different from the standard Ultra-Thin Glass (UTG) used by competitors like Samsung. The goal is to create a panel that does not show a valley or ridge after thousands of folds.
Apple is reportedly evaluating UFG panels that feature uneven thickness. This engineering trick involves using thinner glass specifically in the folding area to maximize flexibility. The rest of the panel retains thicker glass to ensure the screen remains durable against drops and scratches.
This uneven distribution allows the display to bend without creating permanent stress marks along the hinge.
Current market leaders use glass that is uniform in thickness. This often results in a deformation that users can feel when they swipe their finger across the center of the screen. Apple appears to be prioritizing the tactile experience above being first to market.

“Apple is transitioning from design validation to early production validation. Big hardware decisions are being locked in now.”
The manufacturing process for this type of glass is incredibly complex. It requires precise chemical etching to create the necessary variations in thickness without making the glass brittle. If successful, this could set a new standard for the entire mobile industry.
Design Dimensions And Form Factor Rumors
The wait for the iPhone Fold involves more than just the screen material.
Fresh reports have shed light on the potential physical dimensions of the device. The leaks point toward a book-style foldable rather than a clamshell flip phone. This aligns with Apple’s tendency to position “Pro” devices as productivity powerhouses.
The outer cover display is expected to measure between 5.3 and 5.5 inches. This would make the phone relatively compact when closed compared to some massive Android alternatives. It suggests a focus on one-handed usability for quick tasks.
When unfolded the inner screen will reportedly expand to a massive 7.8 inches.
This size effectively turns the iPhone into an iPad Mini replacement. The user can view full-sized apps, multitask with ease and consume media on a canvas that fits in a pocket.
Here is a breakdown of the leaked dimensions currently being tested:
- Folded Size: 120.6mm x 83.8mm
- Unfolded Size: 167.6mm x 120.6mm
- Open Thickness: 4.8mm
- Outer Screen: 5.5 inches (approx)
- Inner Screen: 7.8 inches (approx)
The thickness figure is particularly impressive. At just 4.8mm when open, the device would be one of the thinnest gadgets Apple has ever produced. This engineering feat requires shrinking the battery and logic board components significantly.
High Risks And Even Higher Prices
Innovative technology always comes with a steep price tag during the early adoption phase.
Industry analysts predict that the iPhone Fold will be the most expensive phone in Apple’s lineup. Estimates place the retail price somewhere between $2,000 and $2,500. This places it well above the current iPhone Pro Max pricing structure.
The high cost is attributed to the low yield rates of the specialized UFG panels.
If the glass breaks during the manufacturing process, the entire panel must be scrapped. Apple is reportedly working with two different Chinese display manufacturers to test these solutions. This competition between suppliers helps Apple secure better pricing and quality assurance.
The 2026 launch window suggests that Apple is not in a rush to compete with the Samsung Galaxy Z Fold series or the Google Pixel 9 Pro Fold. The company historically waits until a technology matures before releasing its own polished version.
The timeline implies that we are currently in the critical “validation” phase. This is where engineers stress-test the components to ensure they can survive years of daily abuse.
Key Challenges Apple Must Overcome:
- Hinge Durability: Preventing dust and debris from entering the mechanism.
- Battery Life: Powering two high-resolution screens with a thin battery cell.
- Software Optimization: Adapting iOS to transition seamlessly between open and closed states.
- Crease Visibility: Ensuring the UFG panel stays smooth after 200,000 folds.
The Future Of The Smartphone Market
The introduction of an iPhone Fold will likely legitimize the foldable category for the general public.
While Android manufacturers have been iterating on this form factor for five years, adoption has remained a niche. App developers often neglect to optimize their software for square aspect ratios.
An entry from Apple forces the entire developer ecosystem to adapt.
Once an iPhone Fold exists, popular apps like Instagram, TikTok and Microsoft Office will likely update their interfaces to support large inner screens. This benefits the entire industry including Android users who have suffered from poor app optimization.
The stakes are incredibly high for Apple. A device that costs over $2,000 cannot afford to have the screen failures that plagued early Samsung devices. The “uneven thickness” glass strategy proves that Apple is looking for a physics-based solution to a mechanical problem.
We will likely see more leaks regarding the hinge mechanism in the coming months. If Apple manages to kill the crease, it will have solved the single biggest hardware objection to foldable phones.
Summary:
Apple is actively developing an iPhone Fold slated for a 2026 release with a focus on eliminating the screen crease. The company is testing a new Ultra-Thin Flexible Glass (UFG) with uneven thickness to distribute stress and prevent ridges. Leaked specs suggest a 7.8-inch inner display and an ultra-thin 4.8mm profile when unfolded. However, this premium technology will come at a cost, with price estimates reaching up to $2,500.
